text: An article in the Society's magazine, the "Vegetarian Messenger", in 1851 discussed alternatives to shoe leather, which suggests the presence of vegans within the membership who rejected animal use entirely, not only in diet. By the 1886 publication of Henry S. Salt's "A Plea for Vegetarianism and Other Essays", he asserts that, "It is quite true that most—not all—Food Reformers admit into their diet such animal food as milk, butter, cheese, and eggs..." Russell Thacher Trall's "The Hygeian Home Cook-Book" published in 1874 is the first known vegan cookbook in America. The book contains recipes "without the employment of milk, sugar, salt, yeast, acids, alkalies, grease, or condiments of any kind." An early vegan cookbook, Rupert H. Wheldon's "No Animal Food: Two Essays and 100 Recipes", was published by C. W. Daniel in 1910. The consumption of milk and eggs became a battleground over the following decades. There were regular discussions about it in the "Vegetarian Messenger"; it appears from the correspondence pages that many opponents of veganism came from vegetarians.

text: During a visit to London in 1931, Mahatma Gandhi—who had joined the Vegetarian Society's executive committee when he lived in London from 1888 to 1891—gave a speech to the Society arguing that it ought to promote a meat-free diet as a matter of morality, not health. Lacto-vegetarians acknowledged the ethical consistency of the vegan position but regarded a vegan diet as impracticable and were concerned that it might be an impediment to spreading vegetarianism if vegans found themselves unable to participate in social circles where no non-animal food was available. This became the predominant view of the Vegetarian Society, which in 1935 stated: "The lacto-vegetarians, on the whole, do not defend the practice of consuming the dairy products except on the ground of expediency."


title: Veganism

text: In August 1944, several members of the Vegetarian Society asked that a section of its newsletter be devoted to non-dairy vegetarianism. When the request was turned down, Donald Watson, secretary of the Leicester branch, set up a new quarterly newsletter in November 1944, priced tuppence. He called it "The Vegan News". The word "vegan" was invented by Watson and Dorothy Morgan, a schoolteacher he would later marry. The word is based on "the first three and last two letters of 'vegetarian because it marked, in Mr Watson's words, "the beginning and end of vegetarian". "The Vegan News" asked its readers if they could think of anything better than "vegan" to stand for "non-dairy vegetarian". They suggested "allvega", "neo-vegetarian", "dairyban", "vitan", "benevore", "sanivores", and "beaumangeur".


title: Veganism

text: The first edition attracted more than 100 letters, including from George Bernard Shaw, who resolved to give up eggs and dairy. The new Vegan Society held its first meeting in early November at the Attic Club, 144 High Holborn, London. Those in attendance were Donald Watson, Elsie B. Shrigley, Fay K. Henderson, Alfred Hy Haffenden, Paul Spencer and Bernard Drake, with Mme Pataleewa (Barbara Moore, a Russian-British engineer) observing. World Vegan Day is held every 1 November to mark the founding of the Society and the month of November is considered by the Society to be World Vegan Month.


title: Veganism

text: "The Vegan News" changed its name to "The Vegan" in November 1945, by which time it had 500 subscribers. It published recipes and a "vegan trade list" of animal-free products, such as toothpastes, shoe polishes, stationery and glue. Vegan books appeared, including "Vegan Recipes" by Fay K. Henderson (1946) and "Aids to a Vegan Diet for Children" by Kathleen V. Mayo (1948).


title: Veganism

text: The Vegan Society soon made clear that it rejected the use of animals for any purpose, not only in diet. In 1947, Watson wrote: "The vegan renounces it as superstitious that human life depends upon the exploitation of these creatures whose feelings are much the same as our own ...". From 1948, "The Vegan"s front page read: "Advocating living without exploitation", and in 1951, the Society published its definition of "veganism" as "the doctrine that man should live without exploiting animals". In 1956, its vice-president, Leslie Cross, founded the Plantmilk Society; and in 1965, as Plantmilk Ltd and later Plamil Foods, it began production of one of the first widely distributed soy milks in the Western world.


title: Veganism

text: The first vegan society in the United States was founded in 1948 by Catherine Nimmo and Rubin Abramowitz in California, who distributed Watson's newsletter. In 1960, H. Jay Dinshah founded the American Vegan Society (AVS), linking veganism to the concept of "ahimsa", "non-harming" in Sanskrit. According to Joanne Stepaniak, the word "vegan" was first published independently in 1962 by the "Oxford Illustrated Dictionary", defined as "a vegetarian who eats no butter, eggs, cheese, or milk".


title: Veganism

text: The European Commission was granted the power to adopt an implementing act on food information related to suitability of a food for vegans by the European Parliament and the Council of the European Union in article 36 of Regulation (EU) No 1169/2011. The German consumer protection minister conference approved a definition for food suitable for vegans on 22 April 2016. The European Vegetarian Union adopted this text for a proposal for a legally binding definition based on Regulation (EU) No 1169/2011 in July 2019.


title: Veganism

text: In 2021, the International Organization for Standardization published standard ISO 23662 on "definitions and technical criteria for foods and food ingredients suitable for vegetarians or vegans and for labelling and claims".


title: Veganism

text: In the 1960s and 1970s, a vegetarian food movement emerged as part of the counterculture in the United States that focused on concerns about diet, the environment, and a distrust of food producers, leading to increasing interest in organic gardening. One of the most influential vegetarian books of that time was Frances Moore Lappé's 1971 text, "Diet for a Small Planet". It sold more than three million copies and suggested "getting off the top of the food chain".


title: Veganism

text: The following decades saw research by a group of scientists and doctors in the United States, including physicians Dean Ornish, Caldwell Esselstyn, Neal D. Barnard, John A. McDougall, Michael Greger, and biochemist T. Colin Campbell, who argued that diets based on animal fat and animal protein, such as the Western pattern diet, were detrimental to health. They produced a series of books that recommend vegan or vegetarian diets, including McDougall's "The McDougall Plan" (1983), John Robbins's "Diet for a New America" (1987), which associated meat eating with environmental damage, and "Dr. Dean Ornish's Program for Reversing Heart Disease" (1990). In 2003 two major North American dietitians' associations indicated that well-planned vegan diets were suitable for all life stages. This was followed by the film "Earthlings" (2005), Campbell's "The China Study" (2005), Rory Freedman and Kim Barnouin's "Skinny Bitch" (2005), Jonathan Safran Foer's "Eating Animals" (2009), and the film "Forks over Knives" (2011).


title: Veganism

text: In the 1980s, veganism became associated with punk subculture and ideologies, particularly straight edge hardcore punk in the United States; and anarcho-punk in the United Kingdom. This association continues on into the 21st century, as evinced by the prominence of vegan punk events such as Fluff Fest in Europe.


title: Veganism

text: The vegan diet became increasingly mainstream in the 2010s, especially in the latter half. "The Economist" declared 2019 "the year of the vegan". Chain restaurants began marking vegan items on their menus and supermarkets improved their selection of vegan-processed food.


title: Veganism

text: The global mock-meat market increased by 18 percent between 2005 and 2010, and in the United States by eight percent between 2012 and 2015, to $553 million a year. The Vegetarian Butcher (), the first known vegetarian butcher shop, selling mock meats, opened in the Netherlands in 2010, while America's first vegan butcher, the Herbivorous Butcher, opened in Minneapolis in 2016. Since 2017, more than 12,500 chain restaurant locations have begun offering Beyond Meat and Impossible Foods products including Carl's Jr. outlets offering Beyond Burgers and Burger King outlets serving Impossible Whoppers. Plant-based meat sales in the U.S grew 37% between 2017 and 2019.


title: Veganism

text: In 2011, Europe's first vegan supermarkets appeared in Germany: Veganz in Berlin and Vegilicious in Dortmund. In 2013, the Oktoberfest in Munich (traditionally a meat-heavy event) offered vegan dishes for the first time in its 200-year history.


title: Veganism

text: By 2016, 49% of Americans were drinking plant milk, and 91% still drank dairy milk. In the United Kingdom, the plant milk market increased by 155 percent in two years, from 36 million litres (63 million imperial pints) in 2011 to 92 million (162 million imperial pints) in 2013. There was a 185% increase in new vegan products between 2012 and 2016 in the UK. In 2017, the United States School Nutrition Association found 14% of school districts across the country were serving vegan school meals compared to 11.5% of schools offering vegan lunch in 2016, reflecting a change happening in many parts of the world, including Brazil and England.


title: Veganism

text: In total, , the largest share of vegan consumers globally currently reside in Asia Pacific with nine percent of people following a vegan diet. In 2017, veganism rose in popularity in Hong Kong and China, particularly among millennials. China's vegan market was estimated to rise by more than 17% between 2015 and 2020, which is expected to be "the fastest growth rate internationally in that period". This exceeds the projected growth in the second and third fastest-growing vegan markets internationally in the same period, the United Arab Emirates (10.6%) and Australia (9.6%) respectively.


title: Veganism

text: In 2018, the book "The End of Animal Farming" by Jacy Reese Anthis argued that veganism will completely replace animal-based food by 2100. The book was featured in "The Guardian", "The New Republic", and "Forbes", among other newspapers and magazines.


title: Veganism

text: The growth of schools serving vegan school meals has increased in recent years with the lunches added by Los Angeles, California in 2018, Portland, Maine in 2019, and New York City in 2022.


title: Veganism

text: In January 2021, 582,538 people from 209 countries and territories signed up for Veganuary, breaking the previous year's record of 400,000. That same month, ONA in France became the first vegan restaurant in the country to receive a Michelin star. Throughout the year, a further 79 plant-based restaurants around the world received Michelin stars. At the end of the year, a poll conducted by "The Guardian" showed that a new high of 36% of the British public were interested in veganism.


title: Veganism

text: The city with the most vegan restaurants per resident in 2021 according to data collected from HappyCow was Chiang Mai (Thailand), followed by Ubud (Bali, Indonesia), Phuket (Thailand), Tel Aviv (Israel), and Lisbon (Portugal).


title: Veganism

text: While vegans broadly abstain from animal products, there are many ways in which animal products are used, and different individuals and organizations that identify with the practice of veganism may use some limited animal products based on philosophy, means or other concerns.


title: Veganism

text: Philosopher Gary Steiner argues that it is not possible to be entirely vegan, because animal use and products are "deeply and imperceptibly woven into the fabric of human society".


title: Veganism

text: "Animal Ingredients A to Z" (2004) and "Veganissimo A to Z" (2013) list which ingredients might be animal-derived. The British Vegan Society's sunflower logo and PETA's bunny logo mean the product is certified vegan, which includes no animal testing. The Leaping Bunny logo signals no animal testing, but it might not be vegan. The Vegan Society criteria for vegan certification are that the product contain no animal products, and that neither the finished item nor its ingredients have been tested on animals by, or on behalf of, the manufacturer or by anyone over whom the manufacturer has control. Its website contains a list of certified products, as does Australia's Choose Cruelty Free (CCF). The British Vegan Society will certify a product only if it is free of animal involvement as far as possible and practical, including animal testing, but "recognises that it is not always possible to make a choice that avoids the use of animals", an issue that was highlighted in 2016 when it became known that the UK's newly introduced £5 note contained tallow.


title: Veganism

text: Like vegetarians, vegans do not eat meat (including beef, pork, poultry, fowl, game, animal seafood). The main difference between a vegan and vegetarian diet is that vegans exclude dairy products and eggs. Ethical vegans avoid them on the premise that their production causes animal suffering and premature death.


title: Veganism

text: In egg production, most male chicks are culled because they do not lay eggs. Egg laying hens also suffer from keel bone fractures due to being bred to produce disproportionately large eggs, with the largest study of its kind showing that 85% of Danish egg laying hens suffer from keel bone fractures.


title: Veganism

text: To obtain milk from dairy cattle, cows are made pregnant to induce lactation; they are kept lactating for three to seven years, then slaughtered. Female calves can be separated from their mothers within 24 hours of birth, and fed milk replacer to retain the cow's milk for human consumption. Most male calves are slaughtered at birth, sent for veal production, or reared for beef.


title: Veganism

text: Many clothing products may be made of animal products such as silk, wool (including lambswool, shearling, cashmere, angora, mohair, and a number of other fine wools), fur, feathers, pearls, animal-derived dyes, leather, snakeskin, or other kinds of skin or animal product. While dietary vegans might use animal products in clothing, toiletries, and similar, ethical veganism extends not only to matters of food but also to the wearing or use of animal products, and rejects the commodification of animals altogether. Most leather clothing is made from cow skins. Some vegans regard the purchase of leather, particularly from cows, as financial support for the meat industry. Vegans may wear clothing items and accessories made of non-animal-derived materials such as hemp, linen, cotton, canvas, polyester, artificial leather (pleather), rubber, and vinyl. Leather alternatives can come from materials such as cork, piña (from pineapples), cactus, and mushroom leather. Some vegan clothes, in particular leather alternatives, are made of petroleum-based products, which has triggered criticism because of the environmental damage involved in their production.


title: Veganism

text: Vegans replace personal care products and household cleaners containing animal products with products that are vegan. Animal ingredients are ubiquitous because they are relatively inexpensive. After animals are slaughtered for meat, the leftovers are put through a rendering process and some of that material, particularly the fat, is used in toiletries.


title: Veganism

text: Common animal-derived ingredients include: tallow in soap; collagen-derived glycerine, which used as a lubricant and humectant in many haircare products, moisturizers, shaving foams, soaps and toothpastes; lanolin from sheep's wool is often found in lip balm and moisturizers; stearic acid is a common ingredient in face creams, shaving foam and shampoos, (as with glycerine, it can be plant-based, but is usually animal-derived); Lactic acid, an alpha-hydroxy acid derived from animal milk, is used in moisturizers; allantoin— from the comfrey plant or cows' urine —is found in shampoos, moisturizers and toothpaste; and carmine from scale insects, such as the female cochineal, is used in food and cosmetics to produce red and pink shades;


title: Veganism

text: Beauty Without Cruelty, founded as a charity in 1959, was one of the earliest manufacturers and certifiers of animal-free personal care products.


title: Veganism

text: Vegan groups disagree about insect products. Neither the Vegan Society nor the American Vegan Society considers honey, silk, and other insect products as suitable for vegans. Some vegans believe that exploiting the labor of bees and harvesting their energy source is immoral, and that commercial beekeeping operations can harm and even kill bees. Insect products can be defined much more widely, as commercial bees are used to pollinate about 100 different food crops.


title: Veganism

text: Due to the environmental impact of meat-based pet food and the ethical problems it poses for vegans, some vegans extend their philosophy to include the diets of pets. This is particularly true for domesticated cats and dogs, for which vegan pet food is both available and nutritionally complete, such as Vegepet. This practice has been met with caution and criticism, especially regarding vegan cat diets because felids are obligate carnivores. Nutritionally complete vegan pet diets are comparable to meat-based ones for cats and dogs. A 2015 study found that 6 out of 24 commercial vegan pet food brands do not meet the Association of American Feed Control Officials (AAFCO) labeling regulations for amino acid adequacy.


title: Veganism

text: A concern is the case of medications, which are routinely tested on animals to ensure they are effective and safe, and may also contain animal ingredients, such as lactose, gelatine, or stearates. There may be no alternatives to prescribed medication or these alternatives may be unsuitable, less effective, or have more adverse side effects. Experimentation with laboratory animals is also used for evaluating the safety of vaccines, food additives, cosmetics, household products, workplace chemicals, and many other substances. Vegans may avoid certain vaccines, such as the flu vaccine, which is commonly produced in chicken eggs. An effective alternative, Flublok, is widely available in the United States.


title: Veganism

text: Farming of fruits and vegetables may include fertilizing the soil with animal manure even on organic farms, possibly causing a concern to vegans for ethical or environmental reasons. "Vegan" (or "animal-free") farming uses plant compost only.


title: Veganism

text: Vegan diets are based on grains and other seeds, legumes (particularly beans), fruits, vegetables, edible mushrooms, and nuts.


title: Veganism

text: Vegan meat alternatives are commonly sold in the form of vegetarian sausage, mince, and veggie burgers. They are often made from soybeans, seitan (wheat gluten), beans, lentils, rice, mushrooms or vegetables. Meat substitutes have been made in China since at least the Tang dynasty (618 to 907 common era), including mock duck made from seitan. They are much newer to Western countries. Some famous Western producers of vegan meat alternatives include Impossible Foods and Beyond Meat. However, in the late 2010s many meat producers and supermarkets also started making their own brands of vegan meat substitutes.


title: Veganism

text: Plant milks—such as soy milk, almond milk, cashew milk, grain milks (oat milk, flax milk and rice milk), hemp milk, and coconut milk—are used in place of cows' or goats' milk. Soy milk provides around 7 g (oz) of protein per cup (240 mL or 8 fl oz), compared with 8 g (2/7oz) of protein per cup of cow's milk. Almond milk is lower in dietary energy, carbohydrates, and protein. Soy milk should not be used as a replacement for breast milk for babies. Babies who are not breastfed may be fed commercial infant formula, normally based on cows' milk or soy. The latter is known as soy-based infant formula or SBIF.


title: Veganism

text: Butter and margarine can be replaced with alternate vegan products. Vegan cheeses are made from seeds, such as sesame and sunflower; nuts, such as cashew, pine nut, and almond; and soybeans, coconut oil, nutritional yeast, tapioca, and rice, among other ingredients; and can replicate the meltability of dairy cheese. Nutritional yeast is a common substitute for the taste of cheese in vegan recipes. Cheese substitutes can be made at home, including from nuts, such as cashews. Yoghurt and cream products can be replaced with plant-based products such as soy yoghurt.


title: Veganism

text: Various types of plant cream have been created to replace dairy cream, and some types of imitation whipped cream are non-dairy.


title: Veganism

text: In the 2010s and 2020s, a number of companies have genetically engineered yeast to produce cow milk proteins, whey, or fat, without the use of cows. These include Perfect Day, Novacca, Motif FoodWorks, Remilk, Final Foods, Imagindairy, Nourish Ingredients, and Circe.


title: Veganism

text: As of 2019 in the United States, there were numerous vegan egg substitutes available, including products used for "scrambled" eggs, cakes, cookies, and doughnuts. Baking powder, silken (soft) tofu, mashed potato, bananas, flaxseeds, and aquafaba from chickpeas can also be used as egg substitutes. Which one of these works depends on the egg property the replacement is meant to emulate. Scrambled tofu for instance replaces scrambled eggs, but tofu does not act as a binding agent for cakes like raw eggs, flaxseeds or bananas do.


title: Veganism

text: Raw veganism, combining veganism and raw foodism, excludes all animal products and food cooked above . A raw vegan diet includes vegetables, fruits, nuts, grain and legume sprouts, seeds, and sea vegetables. There are many variations of the diet, including fruitarianism.


title: Veganism

text: A 2022 review indicated that a vegan diet may be effective for reducing body weight, lowering the risk of cancer, and providing a lower risk of all-cause mortality. People on a vegan diet with diabetes or cardiovascular diseases may have lower levels of disease biomarkers.


title: Veganism

text: A 2022 meta-analysis found moderate evidence that adhering to a vegan diet for at least 12 weeks may be effective in individuals with overweight or type 2 diabetes to induce a meaningful decrease in body weight and improve glycemia.


title: Veganism

text: A 2021 Cochrane review of randomized controlled trials found that there is "currently insufficient information to draw conclusions about the effects of vegan dietary interventions on cardiovascular disease risk factors". A 2018 meta-analysis of observational studies concluded that "In most countries, a vegan diet is associated with a more favourable cardio-metabolic profile compared to an omnivorous diet". A 2022 meta-analysis of prospective cohort studies concluded that vegan diets are associated with reduced risk of Ischemic Heart Disease, but no clear association was found for cardiovascular disease and stroke.


title: Veganism

text: A 2020 review of inflammation biomarkers found that a vegan diet was associated with lower levels of C-reactive protein compared to omnivores. There is inconsistent evidence for vegan diets providing an effect on metabolic syndrome. There is tentative evidence of an association between vegan diets and a reduced risk of cancer. A vegan diet without caloric restriction may reduce high blood pressure similarly to diets recommended by medical societies and portion-controlled diets. Vegans may be at risk of low bone mineral density.


title: Veganism

text: The Academy of Nutrition and Dietetics and Dietitians of Canada state that properly planned vegetarian or vegan diets are appropriate for all life stages, including pregnancy and lactation. The Australian National Health and Medical Research Council similarly recognizes a well-planned vegan diet as viable for any age, as does the British Dietetic Association, British National Health Service and the Canadian Pediatric Society.


title: Veganism

text: The does not recommend a vegan diet for babies, children and adolescents, or for pregnancy or breastfeeding.


title: Veganism

text: As of 2022, 45% of government nutritional guidelines discuss vegan meat or milk alternatives (or both).


title: Veganism

text: The Academy of Nutrition and Dietetics and Dietitians of Canada consider well-planned vegetarian and vegan diets "appropriate for individuals during all stages of the lifecycle, including pregnancy, lactation, infancy, childhood, and adolescence, and for athletes". The German Society for Nutrition cautioned against a vegan diet for pregnant women, breastfeeding women, babies, children, and adolescents. The position of the Canadian Pediatric Society is that "well-planned vegetarian and vegan diets with appropriate attention to specific nutrient components can provide a healthy alternative lifestyle at all stages of fetal, infant, child and adolescent growth. It is recommended that attention should be given to nutrient intake, particularly protein, vitamins B and D, essential fatty acids, iron, zinc, and calcium.


title: Veganism

text: Vegan diets tend to be high in dietary fiber, folate, vitamins C and E, potassium, magnesium, and unsaturated fats. However, consuming no animal products increases the risk of deficiencies of vitamins B and D, calcium, iron, and omega-3 fatty acids.


title: Veganism

text: The American Academy of Nutrition and Dietetics states that special attention may be necessary to ensure that a vegan diet will provide adequate amounts of vitamin B, omega-3 fatty acids, vitamin D, calcium, iodine, iron, and zinc. It also states that concern that vegans and vegan athletes may not consume an adequate amount and quality of protein is unsubstantiated.


title: Veganism

text: These nutrients are available in plant foods, with the exception of vitamin B, which can be obtained only from B-fortified vegan foods or supplements. Iodine may also require supplementation, such as using iodized salt. Vitamin B deficiency occurs in up to 80% of vegans that do not supplement with vitamin B.


title: Veganism

text: Ethical veganism is based on opposition to speciesism, the assignment of value to individuals based on (animal) species membership alone. Divisions within animal rights theory include the utilitarian, protectionist approach, which pursues improved conditions for animals. It also pertains to the rights-based abolitionism, which seeks to end human ownership of non-humans, including as pets. Abolitionists argue that protectionism serves only to make the public feel that animal use can be morally unproblematic (the "happy meat" position).


title: Veganism

text: Donald Watson, co-founder of The Vegan Society, stated in response to a question on why he was an ethical vegan, "If an open-minded, honest person pursues a course long enough, and listens to all the criticisms, and in one's own mind can satisfactorily meet all the criticisms against that idea, sooner or later one's resistance against what one sees as evil tradition has to be discarded." On bloodsports, he has said that "to kill creatures for fun must be the very dregs," and that vivisection and animal experimentation "is probably the cruelest of all Man's attack on the rest of Creation." He has also stated that "vegetarianism, whilst being a necessary stepping-stone, between meat eating and veganism, is only a stepping stone."


title: Veganism

text: Alex Hershaft, co-founder of the Farm Animal Rights Movement and Holocaust survivor, states he "was always bothered by the idea of hitting a beautiful, living, innocent animal over the head, cutting him up into pieces, then shoving the pieces into [his] mouth," and that his experiences in the Nazi Holocaust allowed him "to empathize with the conditions of animals in factory farms, auction yards, and slaughterhouses" because he "knows firsthand what it's like to be treated like a worthless object." Several animal rights activists including Isaac Bashevis Singer, Gary Yourofsky and Karen Davis have compared the cruel treatment of animals in CAFOs and slaughterhouses to the Holocaust.


title: Veganism

text: Law professor Gary Francione, an abolitionist, argues that all sentient beings should have the right not to be treated as property, and that adopting veganism must be the baseline for anyone who believes that non-humans have intrinsic moral value. Philosopher Tom Regan, also a rights theorist, argues that animals possess value as "subjects-of-a-life", because they have beliefs, desires, memory and the ability to initiate action in pursuit of goals. The right of subjects-of-a-life not to be harmed can be overridden by other moral principles, but Regan argues that pleasure, convenience and the economic interests of farmers are not weighty enough. Philosopher Peter Singer, a protectionist and utilitarian, argues that there is no moral or logical justification for failing to count animal suffering as a consequence when making decisions, and that killing animals should be rejected unless necessary for survival. Despite this, he writes that "ethical thinking can be sensitive to circumstances", and that he is "not too concerned about trivial infractions".


title: Veganism

text: An argument proposed by Bruce Friedrich, also a protectionist, holds that strict adherence to veganism harms animals, because it focuses on personal purity, rather than encouraging people to give up whatever animal products they can. For Francione, this is similar to arguing that, because human-rights abuses can never be eliminated, we should not defend human rights in situations we control. By failing to ask a server whether something contains animal products, we reinforce that the moral rights of animals are a matter of convenience, he argues. He concludes from this that the protectionist position fails on its own consequentialist terms.


title: Veganism

text: Philosopher Val Plumwood maintained that ethical veganism is "subtly human-centred", an example of what she called "human/nature dualism" because it views humanity as separate from the rest of nature. Ethical vegans want to admit non-humans into the category that deserves special protection, rather than recognize the "ecological embeddedness" of all. Plumwood wrote that animal food may be an "unnecessary evil" from the perspective of the consumer who "draws on the whole planet for nutritional needs"—and she strongly opposed factory farming—but for anyone relying on a much smaller ecosystem, it is very difficult or impossible to be vegan.


title: Veganism

text: Bioethicist Ben Mepham, in his review of Francione and Garner's book "The Animal Rights Debate: Abolition or Regulation?", concludes that "if the aim of ethics is to choose the right, or best, course of action in specific circumstances 'all things considered', it is arguable that adherence to such an absolutist agenda is simplistic and open to serious self-contradictions. Or, as Farlie puts it, with characteristic panache: 'to conclude that veganism is the "only ethical response" is to take a big leap into a very muddy pond'." He cites as examples the adverse effects on animal wildlife derived from the agricultural practices necessary to sustain most vegan diets and the ethical contradiction of favoring the welfare of domesticated animals but not that of wild animals; the imbalance between the resources that are used to promote the welfare of animals as opposed to those destined to alleviate the suffering of the approximately one billion human beings who undergo malnutrition, abuse, and exploitation; the focus on attitudes and conditions in western developed countries, leaving out the rights and interests of societies whose economy, culture and, in some cases, survival rely on a symbiotic relationship with animals.


title: Veganism

text: David Pearce, a transhumanist philosopher, has argued that humanity has a "hedonistic imperative" to not merely avoid cruelty to animals or abolish the ownership of non-human animals, but also to redesign the global ecosystem such that wild animal suffering ceases to exist. In the pursuit of abolishing suffering itself, Pearce promotes predation elimination among animals and the "cross-species global analogue of the welfare state". Fertility regulation could maintain herbivore populations at sustainable levels, "a more civilised and compassionate policy option than famine, predation, and disease". The increasing number of vegans and vegetarians in the transhumanism movement has been attributed in part to Pearce's influence.


title: Veganism

text: A growing political philosophy that incorporates veganism as part of its revolutionary praxis is veganarchism, which seeks "total abolition" or "total liberation" for all animals, including humans. Veganarchists identify the state as unnecessary and harmful to animals, both human and non-human, and advocate for the adoption of a vegan lifestyle within a stateless society. The term was popularized in 1995 with Brian A. Dominick's pamphlet "Animal Liberation and Social Revolution", described as "a vegan perspective on anarchism or an anarchist perspective on veganism".


title: Veganism

text: Direct action is a common practice among veganarchists (and anarchists generally) with groups like the Animal Liberation Front (ALF), the Animal Rights Militia (ARM), the Justice Department (JD) and Revolutionary Cells – Animal Liberation Brigade (RCALB) often engaging in such activities, sometimes criminally, to further their goals. Steven Best, animal rights activist and professor of philosophy at the University of Texas at El Paso, is an advocate of this approach, and has been critical of vegan activists like Francione for supporting animal liberation, but not total liberation, which would include not only opposition to "the property status of animals", but also "a serious critique of capitalism, the state, property relations, and commodification dynamics in general." In particular, he criticizes the focus on the simplistic and apolitical "Go Vegan" message directed mainly at wealthy Western audiences, while ignoring people of color, the working class and the poor, especially in the developing world, noting that "for every person who becomes vegan, a thousand flesh eaters arise in China, India and Indonesia." The "faith in the singular efficacy of conjectural education and moral persuasion," Best writes, is no substitute for "direct action, mass confrontation, civil disobedience, alliance politics, and struggle for radical change." Donald Watson has stated that he "respects the people enormously who do it, believing that it's the most direct and quick way to achieve their ends." Sociologist David Nibert of Wittenberg University posits that any movement towards global justice would necessitate not only the abolition of animal exploitation, particularly as a food source for humans, but also transitioning towards a socioeconomic alternative to the capitalist system, both of which dovetail into what he refers to as the animal–industrial complex.


title: Veganism

text: Some vegans also embrace the philosophy of anti-natalism, as they see the two as complementary in terms of "harm reduction" to animals and the environment.

text: Vegan social psychologist Melanie Joy described the ideology in which people support the use and consumption of animal products as carnism, as a sort of opposite to veganism.


title: Veganism

text: The Vegan Society has written, "by extension, [veganism] promotes the development and use of animal-free alternatives for the benefit of humans." Many ethical vegans and vegan organizations cite the poor working conditions of slaughterhouse workers as a reason to reject animal products. The first vegan activist, Donald Watson, has stated, "If these butchers and vivisectors weren't there, could we perform the acts that they are doing? And, if we couldn't, we have no right to expect them to do it on our behalf. Full stop! That simply compounds the issue. It means that we're not just exploiting animals; we're exploiting human beings."

text: Environmental vegans focus on conservation, rejecting the use of animal products on the premise that fishing, hunting, trapping and farming, particularly factory farming, are environmentally unsustainable.


title: Veganism

text: According to a 2006 United Nations Food and Agriculture Organization report, "Livestock's Long Shadow", around 26% of the planet's terrestrial surface is devoted to livestock grazing. The UN report also concluded that livestock farming (mostly of cows, chickens and pigs) affects the air, land, soil, water, biodiversity and climate change. Livestock consumed 1,174 million tonnes of food in 2002—including 7.6 million tonnes of fishmeal and 670 million tonnes of cereals, one-third of the global cereal harvest. Paul Watson of the Sea Shepherd Conservation Society called pigs and chicken "major aquatic predators", because livestock eat 40 percent of the fish that are caught.


title: Veganism

text: A 2010 UN report, "Assessing the Environmental Impacts of Consumption and Production", argued that animal products "in general require more resources and cause higher emissions than plant-based alternatives". It proposed a move away from animal products to reduce environmental damage.


title: Veganism

text: A 2015 study determined that significant biodiversity loss can be attributed to the growing demand for meat, which is a significant driver of deforestation and habitat destruction, with species-rich habitats being converted to agriculture for livestock production. A 2017 study by the World Wildlife Fund found that 60% of biodiversity loss can be attributed to the vast scale of feed crop cultivation needed to rear tens of billions of farm animals, which puts an enormous strain on natural resources resulting in an extensive loss of lands and species. In November 2017, 15,364 world scientists signed a warning to humanity calling for, among other things, "promoting dietary shifts towards mostly plant-based foods".


title: Veganism

text: A 2018 study found that global adoption of plant-based diets would reduce agricultural land use by 76% (3.1 billion hectares, an area the size of Africa) and cut total global greenhouse gas emissions by 28%. Half of this emissions reduction came from avoided emissions from animal production including methane and nitrous oxide, and half came from trees re-growing on abandoned farmland which remove carbon dioxide from the air. The authors conclude that avoiding meat and diary is the "single biggest way" to reduce one's impact on Earth.


title: Veganism

text: The 2019 IPBES "Global Assessment Report on Biodiversity and Ecosystem Services" found that industrial agriculture and overfishing are the primary drivers of the extinction crisis, with the meat and dairy industries having a substantial impact. On 8 August 2019, the IPCC released a summary of the 2019 special report which asserted that a shift towards plant-based diets would help to mitigate and adapt to climate change.


title: Veganism

text: A 2022 study found that for high-income nations alone 100 billion tons of carbon dioxide could be removed from the air by the end of the century through a shift to plant-based diets and re-wilding of farmland. The researchers coined the term "double climate dividend" to describe the effect that re-wilding after a diet shift can have. However, the researchers note that "We don't have to be purist about this, even just cutting animal intake would be helpful. If half of the public in richer regions cut half the animal products in their diets, you're still talking about a massive opportunity in environmental outcomes and public health".

text: One of the leading activists and scholars of feminist animal rights is Carol J. Adams. Her premier work, "The Sexual Politics of Meat: A Feminist-Vegetarian Critical Theory" (1990), noted the relationship between feminism and meat consumption. Since the release of "The Sexual Politics of Meat", Adams has published several other works, including essays, books, and keynote addresses. In one of her speeches, "Why feminist-vegan now?"—adapted from her original address at the "Minding Animals" conference in Newcastle, Australia (2009)—Adams stated that "the idea that there was a connection between feminism and vegetarianism came to [her] in October 1974", illustrating that the concept of feminist veganism has been around for nearly half a century. Other authors have echoed Adams' ideas while also expanding on them. Feminist scholar Angella Duvnjak stated in "Joining the Dots: Some Reflections on Feminist-Vegan Political Practice and Choice" that she was met with opposition when she pointed out the connection between feminist and vegan ideals, even though the connection seemed more than obvious to her and other scholars (2011).


title: Veganism

text: One of the central concepts that animates feminist veganism is the idea that there is a connection between the oppression of women and the oppression of animals. For example, Marjorie Spiegal compared the consumption or servitude of animals for human gain to slavery. This connection is further mirrored by feminist vegan writers like Carrie Hamilton, who pointed out that violent "rapists sometimes exhibit behavior that seems to be patterned on the mutilation of animals" suggesting there is a parallel between the violence of rape and animal cruelty.


title: Veganism

text: Feminist veganism also relates to feminist thought through the common critique of the capitalist means of production. In an interview with Carol J. Adams, she highlighted "meat eating as the ultimate capitalist product, because it takes so much to make the product, it uses up so many resources". This extensive use of resources for meat production is discouraged in favor of using that productive capacity for other food products that have a less detrimental impact on the environment.


title: Veganism

text: Streams within a number of religious traditions encourage veganism, sometimes on ethical or environmental grounds.  Scholars have especially noted the growth in the twenty-first century of Jewish veganism and Jain veganism. Some interpretations of Christian vegetarianism, Hindu vegetarianism, and Buddhist vegetarianism also recommend or mandate a vegan diet.


title: Veganism

text: Donald Watson argued, "If Jesus were alive today, he'd be an itinerant vegan propagandist instead of an itinerant preacher of those days, spreading the message of compassion, which, as I see it, is the only useful part of what religion has to offer and, sad as it seems, I doubt if we have to enroll our priest as a member of the Vegan Society."


title: Veganism

text: In the US, Black veganism is a social and political philosophy as well as a diet. It connects the use of non-human animals with other social justice concerns such as racism, and with the lasting effects of slavery, such as the subsistence diets of enslaved people enduring as familial and cultural food traditions. Dietary changes caused by the Great Migration also meant former farmers, who had previously been able to grow or forage their own vegetables, became reliant on processed foods.


title: Veganism

text: According to AshEL Eldridge, an Oakland activist, the movement is about the Black community reclaiming its food sovereignty and "decolonizing" the diet of Black Americans. According to Shah, the area where most vegans of color feel the greatest rift with mainstream veganism is in mainstream veganism's failure to recognize the intersectionality with other social justice issues such as food access.


title: Veganism

text: PETA columnist Zachary Tolivar noted he had often heard Black veganism called "a revolutionary act" because it often involves rejecting both family tradition and systemic oppression. Amirah Mercer described it as "revoking my own Black card" and said that for US Blacks, choosing veganism was an act of protest against disenfranchisement by governmental health care and food policy.


title: Veganism

text: In 2021, vegan climate activist Greta Thunberg called for more vegan food production and consumption worldwide. Parties like Tierschutzpartei in Germany and PACMA in Spain have pro-vegan agendas. They cooperate via Animal Politics EU. In the European Union, meat producers and vegans argue whether vegan food products should be allowed to use labels like "sausages" or "burgers" for vegan food. The EU currently bans labeling with dairy-related words like "almond milk", a rule instated in 2017. , six countries in Europe apply higher value-added tax (VAT) rates to vegan plant milk than to cows' milk, which pro-vegan activists have called discrimination.

text: In the below chart, polls with larger sample sizes are preferred over those with smaller sample size.


title: Veganism

text: Multiple symbols have been developed to represent veganism. Several are used on consumer packaging, including the Vegan Society trademark and the Vegan Action logo, to indicate products without animal-derived ingredients. Various symbols may also be used by members of the vegan community to represent their identity and in the course of animal rights activism, such as a vegan flag.


title: Veganism

text: Veganism is often misrepresented in media. Some argue that veganism has been dismissed in news media or that clickbait culture often portrays feminists and vegans as "irrational extremists." This is because in Western societies, "meat-based diets are the norm" with those who avoid meat still representing "a small minority," with more women than men as vegan and vegetarian, with women being "under-represented in the mass media," the latter influencing more to be vegetarians. Others have noted those who are vegetarian and vegan are met with "acceptance, tolerance, or hostility" after they divulge they are vegetarian or vegan. There are a number of vegan stereotypes, including claims they hate meat-eaters, are always hungry, weak, angry, or moralistic. The hatred of vegans has been termed as vegaphobia by some individuals. Farhad Manjoo, in 2019, stated that "preachy vegans are something of a myth," and argued that in pop culture, and generally, it is "still widely acceptable to make fun of vegans."


title: Veganism

text: Often vegan or vegetarian characters are portrayed as fringe characters, although other novels cast them as protagonists or encourage people to become vegetarians or vegans. Some have argued that there are more vegan cookbooks than "vegan literature" There also books which introduce "vegan identity to children" or encourage people to "write for" animals. Also, Bruce Banner in "Ultimate Wolverine vs. Hulk" and Karolina Dean in "Runaways", who is also known as Lucy in the Sky or L.S.D., are vegans. The latter is a lesbian, a vegan, and "an ardent animal lover...committed to a life completely free of meat and dairy."

text: The recent series "City of Ghosts" featured a chef, Sonya, who runs a vegan cafe in Leimert Park, Los Angeles. Draculaura in "Monster High" has also been described as "one of the very few outspoken vegan cartoon characters out there".


title: Veganism

text: By the 2010s, social media sites like Instagram became prominent in the promotion of veganism, more than a fad, with people trying to "change the world by being vegan" as stated by various media outlets.


title: Veganism

text: The 2014 documentary film "Cowspiracy" estimates that a vegan, over the course of one year, will save 1.5 million litres of water, 6,607 kg of grain, 1,022 square metres of forest cover, 3,322 kg of , and 365 animal lives compared to the average U.S. diet. According to a 2016 study, if everyone in the U.S. switched to a vegan diet, the country would save $208.2 billion in direct health-care savings, $40.5 billion in indirect health-care savings, $40.5 billion in environmental savings, and $289.1 billion in total savings by 2050. The study also found that if everybody in the world switched to a vegan diet, the global economy would save $684.4 billion in direct health-care savings, $382.6 billion in indirect health-care savings, $569.5 billion in environmental savings, and $1.63 trillion in total savings by 2050.

text: In his 2015 book "Doing Good Better", William MacAskill stated the following (citing numbers from a 2011 book, "Compassion by the pound"):


title: Renewable energy

text: Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. In addition, electrification with renewable energy is more efficient and therefore leads to significant reductions in primary energy requirements.


title: Renewable energy

text: From 2011 to 2021, renewable energy has grown from 20% to 28% of global electricity supply. Fossil energy shrunk from 68% to 62%, and nuclear from 12% to 10%. The share of hydropower decreased from 16% to 15% while power from sun and wind increased from 2% to 10%. Biomass and geothermal energy grew from 2% to 3%. There are 3,146 gigawatts installed in 135 countries, while 156 countries have laws regulating the renewable energy sector. In 2021, China accounted for almost half of the global increase in renewable electricity.


title: Renewable energy

text: Globally there are over 10 million jobs associated with the renewable energy industries, with solar photovoltaics being the largest renewable employer. Renewable energy systems are rapidly becoming more efficient and cheaper and their share of total energy consumption is increasing, with a large majority of worldwide newly installed electricity capacity being renewable. In most countries, photovoltaic solar or onshore wind are the cheapest new-build electricity.


title: Renewable energy

text: Many nations around the world already have renewable energy contributing more than 20% of their total energy supply, with some generating over half their electricity from renewables. A few countries generate all their electricity using renewable energy. National renewable energy markets are projected to continue to grow strongly in the 2020s and beyond. Studies have shown that a global transition to 100% renewable energy across all sectors – power, heat, transport and desalination – is feasible and economically viable. Renewable energy resources exist over wide geographical areas, in contrast to fossil fuels, which are concentrated in a limited number of countries. Deployment of renewable energy and energy efficiency technologies is resulting in significant energy security, climate change mitigation, and economic benefits. However renewables are being hindered by hundreds of billions of dollars of fossil fuel subsidies. In international public opinion surveys there is strong support for renewables such as solar power and wind power. But the International Energy Agency said in 2021 that to reach net zero carbon emissions more effort is needed to increase renewables, and called for generation to increase by about 12% a year to 2030. 47% of respondents to a 2022 European survey from the European Union and the United Kingdom (45%) want their government to focus on the development of renewable energies. This is compared to 37% in both the United States and China when asked to list their priorities on energy. 46% of respondents from China believe that diversifying energy sources should be a top priority, compared to 34% respondents from the European Union, 35% from the United Kingdom, and 39% from the United States. The German government is actively encouraging solar and wind energy to decrease the dependability of conventional energy sources like coal and boost the share of clean energy. Expanding renewable energy sources (37%) and diversifying energy suppliers (39%) is more evenly distributed among American respondents.


title: Renewable energy

text: Renewable energy flows involve natural phenomena such as sunlight, wind, tides, plant growth, and geothermal heat, as the International Energy Agency explains:


title: Renewable energy

text: Renewable energy stands in contrast to fossil fuels, which are being used far more quickly than they are being replenished. Renewable energy resources and significant opportunities for energy efficiency exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency, and technological diversification of energy sources, would result in significant energy security and economic benefits. Solar and wind power have got much cheaper. In some cases it will be cheaper to transition to these sources as opposed to continuing to use the current, inefficient, fossil fuels. It would also reduce environmental pollution such as air pollution caused by the burning of fossil fuels, and improve public health, reduce premature mortalities due to pollution and save associated health costs that could amount to trillions of dollars annually. Multiple analyses of decarbonization strategies have found that quantified health benefits can significantly offset the costs of implementing these strategies.


title: Renewable energy

text: Climate change concerns, coupled with the continuing fall in the costs of some renewable energy equipment, such as wind turbines and solar panels, are driving increased use of renewables. New government spending, regulation and policies helped the industry weather the global financial crisis better than many other sectors. , however, according to the International Renewable Energy Agency, renewables overall share in the energy mix (including power, heat and transport) needs to grow six times faster, in order to keep the rise in average global temperatures "well below" during the present century, compared to pre-industrial levels.


title: Renewable energy

text: A household's solar panels, and batteries if they have them, can often either be used for just that household or if connected to an electrical grid can be aggregated with millions of others. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves. According to the research, a nation must reach a certain point in its growth before it can take use of more renewable energy. In our words, its addition changed how crucial input factors (labor and capital) connect to one another, lowering their overall elasticity and increasing the apparent economies of scale. United Nations' eighth Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity. At the national level, at least 30 nations around the world already have renewable energy contributing more than 20% of energy supply. Although many countries have various policy targets for longer-term shares of renewable energy these tend to be only for the power sector, including a 40% target of all electricity generated for the European Union by 2030.


title: Renewable energy

text: Renewable energy often displaces conventional fuels in four areas: electricity generation, hot water/space heating, transportation, and rural (off-grid) energy services.


title: Renewable energy

text: Solar water heating makes an important contribution to renewable heat in many countries, most notably in China, which now has 70% of the global total (180  GWth). Most of these systems are installed on multi-family apartment buildings and meet a portion of the hot water needs of an estimated 50–60 million households in China. Worldwide, total installed solar water heating systems meet a portion of the water heating needs of over 70 million households. In Sweden, national use of biomass energy has surpassed that of oil. Heat pumps provide both heating and cooling, and also flatten the electric demand curve and are thus an increasing priority Renewable thermal energy is also growing rapidly. About 10% of heating and cooling energy is from renewables.


title: Renewable energy

text: One of the efforts to decarbonize transportation is the increased use of electric vehicles (EVs). Despite that and the use of biofuels, such as biojet, less than 4% of transport energy is from renewables. Occasionally hydrogen fuel cells are used for heavy transport.


title: Renewable energy

text: Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, concentrated solar power (CSP), concentrator photovoltaics (CPV), solar architecture and artificial photosynthesis. Most new renewable energy is solar. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert, and distribute solar energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. Active solar technologies encompass solar thermal energy, using solar collectors for heating, and solar power, converting sunlight into electricity either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP).


title: Renewable energy

text: A photovoltaic system converts light into electrical direct current (DC) by taking advantage of the photoelectric effect. Solar PV has turned into a multi-billion, fast-growing industry, continues to improve its cost-effectiveness, and has the most potential of any renewable technologies together with CSP. Concentrated solar power (CSP) systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Commercial concentrated solar power plants were first developed in the 1980s. CSP-Stirling has by far the highest efficiency among all solar energy technologies.


title: Renewable energy

text: In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries' energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating climate change, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared". Solar power accounts for 505 GW annually, which is about 2% of the world's electricity. Solar energy can be harnessed anywhere that receives sunlight; however, the amount of solar energy that can be harnessed for electricity generation is influenced by weather conditions, geographic location and time of day. According to chapter 6 of the IPCC 2022 climate mitigation report, the global potential of direct solar energy far exceeds that of any other renewable energy resource. It is well beyond the total amount of energy needed in order to support mitigation over the current century. Australia has the largest proportion of solar electricity in the world, supplying 9.9% of the country's electrical demand in 2020. More than 30 per cent of Australian households now have rooftop solar PV, with a combined capacity exceeding 11 GW.


title: Renewable energy

text: Air flow can be used to run wind turbines. Modern utility-scale wind turbines range from around 600 kW to 9 MW of rated power. The power available from the wind is a function of the cube of the wind speed, so as wind speed increases, power output increases up to the maximum output for the particular turbine. Areas where winds are stronger and more constant, such as offshore and high-altitude sites, are preferred locations for wind farms. Typically, full load hours of wind turbines vary between 16 and 57 percent annually but might be higher in particularly favorable offshore sites.


title: Renewable energy

text: Wind-generated electricity met nearly 4% of global electricity demand in 2015, with nearly 63 GW of new wind power capacity installed. Wind energy was the leading source of new capacity in Europe, the US and Canada, and the second largest in China. In Denmark, wind energy met more than 40% of its electricity demand while Ireland, Portugal and Spain each met nearly 20%.


title: Renewable energy

text: Globally, the long-term technical potential of wind energy is believed to be five times total current global energy production, or 40 times current electricity demand, assuming all practical barriers needed were overcome. This would require wind turbines to be installed over large areas, particularly in areas of higher wind resources, such as offshore. As offshore wind speeds average ~90% greater than that of land, offshore resources can contribute substantially more energy than land-stationed turbines.


title: Renewable energy

text: Since water is about 800 times denser than air, even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of energy. Water can generate electricity with a conversion efficiency of about 90%, which is the highest rate in renewable energy. There are many forms of water energy:


title: Renewable energy

text: Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. Of the top 50 countries by percentage of electricity generated from renewables, 46 are primarily hydroelectric. There are now three hydroelectricity stations larger than 10 GW: the Three Gorges Dam in China, Itaipu Dam across the Brazil/Paraguay border, and Guri Dam in Venezuela. Much hydropower is flexible, thus complementing wind and solar.


title: Renewable energy

text: Wave power, which captures the energy of ocean surface waves, and tidal power, converting the energy of tides, are two forms of hydropower with future potential; however, they are not yet widely employed commercially. A demonstration project operated by the Ocean Renewable Power Company on the coast of Maine, and connected to the grid, harnesses tidal power from the Bay of Fundy, location of the world's highest tidal flow. Ocean thermal energy conversion, which uses the temperature difference between cooler deep and warmer surface waters, currently has no economic feasibility.


title: Renewable energy

text: Biomass is biological material derived from living, or recently living organisms. It most often refers to plants or plant-derived materials which are specifically called lignocellulosic biomass. As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into: "thermal", "chemical", and "biochemical" methods. Wood was the largest biomass energy source as of 2012; examples include forest residuessuch as dead trees, branches and tree stumps, yard clippings, wood chips and even municipal solid waste. In the second sense, biomass includes plant or animal matter that can be converted into fibers or other industrial chemicals, including biofuels. Industrial biomass can be grown from numerous types of plants, including miscanthus, switchgrass, hemp, corn, poplar, willow, sorghum, sugarcane, bamboo, and a variety of tree species, ranging from eucalyptus to oil palm (palm oil).


title: Renewable energy

text: Plant energy is produced by crops specifically grown for use as fuel that offer high biomass output per hectare with low input energy. The grain can be used for liquid transportation fuels while the straw can be burned to produce heat or electricity. Plant biomass can also be degraded from cellulose to glucose through a series of chemical treatments, and the resulting sugar can then be used as a first-generation biofuel.


title: Renewable energy

text: Biomass can be converted to other usable forms of energy such as methane gas or transportation fuels such as ethanol and biodiesel. Rotting garbage, and agricultural and human waste, all release methane gasalso called landfill gas or biogas. Crops, such as corn and sugarcane, can be fermented to produce the transportation fuel, ethanol. Biodiesel, another transportation fuel, can be produced from left-over food products such as vegetable oils and animal fats. There is a great deal of research involving algal fuel or algae-derived biomass due to the fact that it is a non-food resource, grows around 20 times faster than other types of food crops, such as corn and soy, and can be grown almost anywhere. Once harvested, it can be fermented to produce biofuels such as ethanol, butanol, and methane, as well as biodiesel and hydrogen. The biomass used for electricity generation varies by region. Forest by-products, such as wood residues, are common in the United States. Agricultural waste is common in Mauritius (sugar cane residue) and Southeast Asia (rice husks).


title: Renewable energy

text: Biofuels include a wide range of fuels which are derived from biomass. The term covers solid, liquid, and gaseous fuels. Liquid biofuels include bioalcohols, such as bioethanol, and oils, such as biodiesel. Gaseous biofuels include biogas, landfill gas and synthetic gas. Bioethanol is an alcohol made by fermenting the sugar components of plant materials and it is made mostly from sugar and starch crops. These include maize, sugarcane and, more recently, sweet sorghum. The latter crop is particularly suitable for growing in dryland conditions, and is being investigated by International Crops Research Institute for the Semi-Arid Tropics for its potential to provide fuel, along with food and animal feed, in arid parts of Asia and Africa.


title: Renewable energy

text: With advanced technology being developed, cellulosic biomass, such as trees and grasses, are also used as feedstocks for ethanol production. Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions. Bioethanol is widely used in the United States and in Brazil. The energy costs for producing bio-ethanol are almost equal to, the energy yields from bio-ethanol. However, according to the European Environment Agency, biofuels do not address global warming concerns. Biodiesel is made from vegetable oils, animal fats or recycled greases. It can be used as a fuel for vehicles in its pure form, or more commonly as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles. Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe. Biofuels provided 2.7% of the world's transport fuel in 2010.


title: Renewable energy

text: Biomass, biogas and biofuels are burned to produce heat/power and in doing so harm the environment. Pollutants such as sulphurous oxides (SO), nitrous oxides (NO), and particulate matter (PM) are produced from the combustion of biomass. The World Health Organization estimates that 3.7 million prematurely died from outdoor air pollution in 2012 while indoor pollution from biomass burning effects over 3 billion people worldwide.


title: Renewable energy

text: High temperature geothermal energy is from thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. Earth's geothermal energy originates from the original formation of the planet and from radioactive decay of minerals (in currently uncertain but possibly roughly equal proportions). The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface. The adjective "geothermal" originates from the Greek roots "geo", meaning earth, and "thermos", meaning heat.


title: Renewable energy

text: The heat that is used for geothermal energy can be from deep within the Earth, all the way down to Earth's core – down. At the core, temperatures may reach over . Heat conducts from the core to the surrounding rock. Extremely high temperature and pressure cause some rock to melt, which is commonly known as magma. Magma convects upward since it is lighter than the solid rock. This magma then heats rock and water in the crust, sometimes up to .


title: Renewable energy

text: Low temperature geothermal refers to the use of the outer crust of the Earth as a thermal battery to facilitate renewable thermal energy for heating and cooling buildings, and other refrigeration and industrial uses. In this form of geothermal, a geothermal heat pump and ground-coupled heat exchanger are used together to move heat energy into the Earth (for cooling) and out of the Earth (for heating) on a varying seasonal basis. Low-temperature geothermal (generally referred to as "GHP") is an increasingly important renewable technology because it both reduces total annual energy loads associated with heating and cooling, and it also flattens the electric demand curve eliminating the extreme summer and winter peak electric supply requirements. Thus low temperature geothermal/GHP is becoming an increasing national priority with multiple tax credit support and focus as part of the ongoing movement toward net zero energy.


title: Renewable energy

text: There are also other renewable energy technologies that are still under development, including cellulosic ethanol, hot-dry-rock geothermal power, and marine energy. These technologies are not yet widely demonstrated or have limited commercialization. Many are on the horizon and may have potential comparable to other renewable energy technologies, but still depend on attracting sufficient attention and research, development and demonstration (RD&D) funding.


title: Renewable energy

text: There are numerous organizations within the academic, federal, and commercial sectors conducting large-scale advanced research in the field of renewable energy. This research spans several areas of focus across the renewable energy spectrum. Most of the research is targeted at improving efficiency and increasing overall energy yields.


title: Renewable energy

text: Multiple government supported research organizations have focused on renewable energy in recent years. Two of the most prominent of these labs are Sandia National Laboratories and the National Renewable Energy Laboratory (NREL), both of which are funded by the United States Department of Energy and supported by various corporate partners.


title: Renewable energy

text: Enhanced geothermal systems (EGS) are a new type of geothermal power technology that does not require natural convective hydrothermal resources. The vast majority of geothermal energy within drilling reach is in dry and non-porous rock. EGS technologies "enhance" and/or create geothermal resources in this "hot dry rock (HDR)" through hydraulic fracturing. EGS and HDR technologies, such as hydrothermal geothermal, are expected to be baseload resources that produce power 24 hours a day like a fossil plant. Distinct from hydrothermal, HDR and EGS may be feasible anywhere in the world, depending on the economic limits of drill depth. Good locations are over deep granite covered by a thick () layer of insulating sediments which slow heat loss. There are HDR and EGS systems currently being developed and tested in France, Australia, Japan, Germany, the U.S., and Switzerland. The largest EGS project in the world is a 25 megawatt demonstration plant currently being developed in the Cooper Basin, Australia. The Cooper Basin has the potential to generate 5,000–10,000 MW.

text: Marine energy (also sometimes referred to as ocean energy) is the energy carried by ocean waves, tides, salinity, and ocean temperature differences. The movement of water in the world's oceans creates a vast store of kinetic energy, or energy in motion. This energy can be harnessed to generate electricity to power homes, transport and industries. The term marine energy encompasses wave powerpower from surface waves, marine current power - power from marine hydrokinetic streams (e.g., the Gulf Stream), and tidal powerobtained from the kinetic energy of large bodies of moving water. Reverse electrodialysis (RED) is a technology for generating electricity by mixing fresh river water and salty sea water in large power cells designed for this purpose; as of 2016, it is being tested at a small scale (50 kW). Offshore wind power is not a form of marine energy, as wind power is derived from the wind, even if the wind turbines are placed over water. The oceans have a tremendous amount of energy and are close to many if not most concentrated populations. Ocean energy has the potential of providing a substantial amount of new renewable energy around the world.

text: Passive daytime radiative cooling (PDRC) uses the coldness of outer space as a renewable energy source to achieve daytime cooling that can be used in many applications, such as indoor space cooling, outdoor urban heat island mitigation, and solar cell efficiency. PDRC surfaces are designed to be high in solar reflectance to minimize heat gain and strong in longwave infrared (LWIR) thermal radiation heat transfer. On a planetary scale, it has been proposed as a way to slow and reverse global warming. PDRC applications are deployed as sky-facing surfaces, similar to other renewable energy sources such as photovoltaic systems and solar thermal collectors. PDRC became possible with the ability to suppress solar heating using photonic metamaterials, first published in a study by Raman et al. to the scientific community in 2014. PDRC applications for indoor space cooling is growing with an estimated "market size of ∼$27 billion in 2025."

text: Artificial photosynthesis uses techniques including nanotechnology to store solar electromagnetic energy in chemical bonds by splitting water to produce hydrogen and then using carbon dioxide to make methanol. Researchers in this field strived to design molecular mimics of photosynthesis that use a wider region of the solar spectrum, employ catalytic systems made from abundant, inexpensive materials that are robust, readily repaired, non-toxic, stable in a variety of environmental conditions and perform more efficiently allowing a greater proportion of photon energy to end up in the storage compounds, i.e., carbohydrates (rather than building and sustaining living cells). However, prominent research faces hurdles, Sun Catalytix a MIT spin-off stopped scaling up their prototype fuel-cell in 2012, because it offers few savings over other ways to make hydrogen from sunlight.

text: Earth emits roughly 10 W of infrared thermal radiation that flows toward the cold outer space. Solar energy hits the surface and atmosphere of the earth and produces heat. Using various theorized devices like emissive energy harvester (EEH) or thermoradiative diode, this energy flow can be converted into electricity. In theory, this technology can be used during nighttime.

text: AuREUS devices (Aurora Renewable Energy & UV Sequestration), which are based on crop wastes can absorb ultraviolet light from the sun and turn it into renewable energy.


title: Renewable energy

text: Renewable energy production from some sources such as wind and solar is more variable and more geographically spread than technology based on fossil fuels and nuclear. While integrating it into the wider energy system is feasible, it does lead to some additional challenges such as increased production volatility and decreased system inertia. Implementation of energy storage, using a wide variety of renewable energy technologies, and implementing a smart grid in which energy is automatically used at the moment it is produced can reduce risks and costs of renewable energy implementation.


title: Renewable energy

text: Sector coupling of the power generation sector with other sectors may increase flexibility: for example the transport sector can be coupled by charging electric vehicles and sending electricity from vehicle to grid. Similarly the industry sector can be coupled by hydrogen produced by electrolysis, and the buildings sector by thermal energy storage for space heating and cooling.


title: Renewable energy

text: Electrical energy storage is a collection of methods used to store electrical energy. Electrical energy is stored during times when production (especially from intermittent sources such as wind power, tidal power, solar power) exceeds consumption, and returned to the grid when production falls below consumption. Pumped-storage hydroelectricity accounts for more than 85% of all grid power storage. Batteries are increasingly being deployed for this and for grid ancillary services and for domestic storage.

text: A May 2022 report by the IEA predicted renewables to remain competitive in 2023 despite rising costs, as fossil fuel costs have risen much faster. The report forecasts almost 200 GW of solar PV to be installed in 2023. China and Europe are both expected to install more renewables than the US, due to uncertainty in US energy policy. The report forecasts biofuel demand to increase in India and Indonesia in 2023, partly due to their transport policies.

text: In July 2014, WWF and the World Resources Institute convened a discussion among a number of major US companies who had declared their intention to increase their use of renewable energy. These discussions identified a number of "principles" which companies seeking greater access to renewable energy considered important market deliverables. These principles included choice (between suppliers and between products), cost competitiveness, longer term fixed price supplies, access to third-party financing vehicles, and collaboration.

text: In 2020 the world renewable hydropower capacity was 1,330 GW. Only a third of the world's estimated hydroelectric potential of 14,000 TWh/year has been developed. New hydropower projects face opposition from local communities due to their large impact, including relocation of communities and flooding of wildlife habitats and farming land. High cost and lead times from permission process, including environmental and risk assessments, with lack of environmental and social acceptance are therefore the primary challenges for new developments. It is popular to repower old dams thereby increasing their efficiency and capacity as well as quicker responsiveness on the grid. Where circumstances permit existing dams such as the Russell Dam built in 1985 may be updated with "pump back" facilities for pumped-storage which is useful for peak loads or to support intermittent wind and solar power. Because dispatchable power is more valuable than VRE countries with large hydroelectric developments such as Canada and Norway are spending billions to expand their grids to trade with neighboring countries having limited hydro.

title: Renewable energy

text: PV uses solar cells assembled into solar panels to convert sunlight into electricity. PV systems range from small, residential and commercial rooftop or building integrated installations, to large utility-scale photovoltaic power station. The predominant PV technology is crystalline silicon, while thin-film solar cell technology accounts for about 10 percent of global photovoltaic deployment. In recent years, PV technology has improved its electricity generating efficiency, reduced the installation cost per watt as well as its energy payback time, and reached grid parity in at least 30 different markets by 2014.

text: Building-integrated photovoltaics or "onsite" PV systems use existing land and structures and generate power close to where it is consumed.


title: Renewable energy

text: Photovoltaics grew fastest in China, followed by Japan and the United States. Solar power is forecasted to become the world's largest source of electricity by 2050, with solar photovoltaics and concentrated solar power contributing 16% and 11%, respectively. This requires an increase of installed PV capacity to 4,600 GW, of which more than half is expected to be deployed in China and India.


title: Renewable energy

text: Commercial concentrated solar power plants were first developed in the 1980s. As the cost of solar electricity has fallen, the number of grid-connected solar PV systems has grown into the millions and utility-scale solar power stations with hundreds of megawatts are being built. Many solar photovoltaic power stations have been built, mainly in Europe, China and the United States. The 1.5 GW Tengger Desert Solar Park, in China is the world's largest PV power station. Many of these plants are integrated with agriculture and some use tracking systems that follow the sun's daily path across the sky to generate more electricity than fixed-mounted systems.

text: Geothermal power is cost effective, reliable, sustainable, and environmentally friendly, but has historically been limited to areas near tectonic plate boundaries. Recent technological advances have expanded the range and size of viable resources, especially for applications such as home heating, opening a potential for widespread exploitation. Geothermal wells release greenhouse gases trapped deep within the earth, but these emissions are usually much lower per energy unit than those of fossil fuels. As a result, geothermal power has the potential to help mitigate global warming if widely deployed in place of fossil fuels.


title: Renewable energy

text: In 2017, the United States led the world in geothermal electricity production with 12.9 GW of installed capacity. The largest group of geothermal power plants in the world is located at The Geysers, a geothermal field in California. The Philippines follows the US as the second highest producer of geothermal power in the world, with 1.9 GW of capacity online.

text: Policies to support renewable energy have been vital in their expansion. Where Europe dominated in establishing energy policy in the early 2000s, most countries around the world now have some form of energy policy.


title: Renewable energy

text: The International Renewable Energy Agency (IRENA) is an intergovernmental organization for promoting the adoption of renewable energy worldwide. It aims to provide concrete policy advice and facilitate capacity building and technology transfer. IRENA was formed in 2009, with 75 countries signing the charter of IRENA. As of April 2019, IRENA has 160 member states. The then United Nations Secretary-General Ban Ki-moon has said that renewable energy can lift the poorest nations to new levels of prosperity, and in September 2011 he launched the UN Sustainable Energy for All initiative to improve energy access, efficiency and the deployment of renewable energy.


title: Renewable energy

text: The 2015 Paris Agreement on climate change motivated many countries to develop or improve renewable energy policies. In 2017, a total of 121 countries adopted some form of renewable energy policy. National targets that year existed in 176 countries. In addition, there is also a wide range of policies at the state/provincial, and local levels. Some public utilities help plan or install residential energy upgrades.

text: Renewable electricity generation by wind and solar is variable. This results in reduced capacity factor and may require keeping some gas-fired power plants or other dispatchable generation on standby until there is enough energy storage, demand response, grid improvement, and/or base load power from non-intermittent sources like hydropower, nuclear power or bioenergy.


title: Renewable energy

text: Solar power plants may compete with arable land, while on-shore wind farms face opposition due to aesthetic concerns and noise, which is impacting both humans and wildlife. In the United States, the Massachusetts Cape Wind project was delayed for years partly because of aesthetic concerns. However, residents in other areas have been more positive. According to a town councilor, the overwhelming majority of locals believe that the Ardrossan Wind Farm in Scotland has enhanced the area. These concerns, when directed against renewable energy, are sometimes described as "not in my back yard" attitude (NIMBY).


title: Renewable energy

text: A 2011 UK Government document states that "projects are generally more likely to succeed if they have broad public support and the consent of local communities. This means giving communities both a say and a stake". In countries such as Germany and Denmark many renewable projects are owned by communities, particularly through cooperative structures, and contribute significantly to overall levels of renewable energy deployment.


title: Renewable energy

text: The market for renewable energy technologies has continued to grow. Climate change concerns and increasing in green jobs, coupled with high oil prices, peak oil, oil wars, oil spills, promotion of electric vehicles and renewable electricity, nuclear disasters and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization. New government spending, regulation and policies helped the industry weather the 2009 economic crisis better than many other sectors.


title: Renewable energy

text: The International Energy Agency has stated that deployment of renewable technologies usually increases the diversity of electricity sources and, through local generation, contributes to the flexibility of the system and its resistance to central shocks.


title: Renewable energy

text: In October 2021, European Commissioner for Climate Action Frans Timmermans suggested "the best answer" to the 2021 global energy crisis is "to reduce our reliance on fossil fuels." He said those blaming the European Green Deal were doing so "for perhaps ideological reasons or sometimes economic reasons in protecting their vested interests." Some critics blamed the European Union Emissions Trading System (EU ETS) and closure of nuclear plants for contributing to the energy crisis. European Commission President Ursula von der Leyen said that Europe is "too reliant" on natural gas and too dependent on natural gas imports. According to Von der Leyen, "The answer has to do with diversifying our suppliers ... and, crucially, with speeding up the transition to clean energy."

text: From around 2010 onwards, the geopolitical impact of the growing use of renewable energy has been discussed. Some argue that former fossil fuels exporters will experience a weakening of their position in international affairs, while countries with abundant renewable energy resources will be strengthened. Also some countries rich in critical materials for renewable energy technologies are expected to rise in importance in international affairs.


title: Renewable energy

text: The GeGaLo index of geopolitical gains and losses assesses how the geopolitical position of 156 countries may change if the world fully transitions to renewable energy resources. Former fossil fuels exporters are expected to lose power, while the positions of former fossil fuel importers and countries rich in renewable energy resources is expected to strengthen. Sourcing of required materials, ownership of key infrastructure assets and the design of grids all require geopolitics consideration.


title: Renewable energy

text: Transitions to renewable energy have many geopolitical implications such as the potential of revenue losses leading to political instability in insufficiently prepared fossil-fuel-exporting economies, albeit it is unclear whether the transition will increase or reduce conflict overall. In particular, a study hypothesizes that a "configuration emerges in which fossil fuel importers are better off decarbonizing, competitive fossil fuel exporters are better off flooding markets and uncompetitive fossil fuel producers—rather than benefitting from 'free-riding'—suffer from their exposure to stranded assets and lack of investment in decarbonization technologies".


title: Renewable energy

text: A study found that transition from fossil fuels to renewable energy systems reduces risks from mining, trade and political dependence because renewable energy systems don't need fuel – they depend on trade only for the acquisition of materials and components during construction.

text: Trade in hydrogen could fundamentally redraw the geography of the global energy trade, and international governance and investments that seek to scale up the hydrogen economy could reduce "the risk of market fragmentation, carbon lock-in, and intensified geo-economic rivalry". Electricity will overtake other energy carriers by 2050, accounting for almost 50% of total energy consumption (up from 22% in 2015). Given the limitations of using solely electricity, clean hydrogen has significant potential in a number of industries. Hydrogen has the potential to be long-term stored in the electricity and heating industries.


title: Renewable energy

text: In 2019, oil and gas companies were listed by Forbes with sales of US$4.8 trillion, about 5% of the global GDP. Net importers such as China and the EU would gain advantages from a transition to low-carbon technologies driven by technological development, energy efficiency or climate change policy, while Russia, the USA or Canada could see their fossil fuel industries nearly shut down. On the other hand, countries with large areas such as Australia, Russia, China, the US, Canada and Brazil and also Africa and the Middle East have a potential for huge installations of renewable energy. The production of renewable energy technologies requires rare-earth elements with new supply chains.

text: Moving to modern renewable energy has very large health benefits due to reducing air pollution from fossil fuels.


title: Renewable energy

text: Renewable sources other than biomass such as wind power, photovoltaics, and hydroelectricity have the advantage of being able to conserve water, lower pollution and reduce emissions.


title: Renewable energy

text: Solar panels change the albedo of the surface, so if used on a very large scale (such as covering 20% of the Sahara Desert), could change global weather patterns.


title: Renewable energy

text: The ability of biomass and biofuels to contribute to a reduction in emissions is limited because both biomass and biofuels emit large amounts of air pollution when burned and in some cases compete with food supply. Furthermore, biomass and biofuels consume large amounts of water and land (sometimes land that could be used for food production). Furthermore, there can be carbon leakage from biomass production.<ref name="10.1016/j.rser.2016.12.109"></ref> Nevertheless, it could still help reduce carbon dioxide emissions and play an important role as a method of dispatchable generation.
