Advantages of Biofuels Availability of Biofuels. Unlike fossil fuels, biofuels are a renewable energy source. Because they are derived from crops that can be harvested annually, or in the case of algae monthly, biofuels are theoretically unlimited. Despite this surface appearance of unlimited availability, biofuels do have restrictions.

However, energy is used in farming and processing the crops, and this can make biofuels as polluting as petroleum-based fuels, depending on what is grown and how it is treated.iofuels: the next batch. Sixty percent of new cars can run on a fuel mix which includes 85% ethanol. The European Union has a target for 2010 that 5.75% of transport fuels should come from biological sources, but the target is unlikely to be met.

What are Biofuels? Fuels that have been extracted from plants and crops are known as biofuels. Of these, the most commonly extracted and used one is Bioethanol or simply Ethanol and Biodiesel. It is blended with gasoline and can be used as an alternative fuel for your car.dvantages of Biofuels. 1. Cost Benefit: As of now, biofuels cost the same in the market as gasoline does. However, the overall cost benefit of using them is much higher. They are cleaner fuels, which means they produce fewer emissions on burning.

How Biofuel is Made How Biofuel is Made. The energy that we get from biofuels originally came from the sun. This solar energy was captured through photosynthesis by the plants used as feedstocks (raw materials) for biofuel production, and stored in the plants' cells. Many different plant materials can be used for biofuel:

What are the advantages and disadvantages of biofuels? Advantages. 1. Biofuels are any solid, liquid or gas that has been derived from biomass. It can be produced from any carbon source that is easily replenished such as plants. This means it is very eco-friendly as the fuel is a renewable resource. The disadvantage of biofuels is that despite being a renewable source of energy the levels of power/energy it produces are not high enough (compared to fossil fuels) to be used commerically i.e. for industry, power stations etc.

1 What are biofuels? 1 What are biofuels? The use of biological material (biomass) as a fuel or lighting material is not new; the earliest evidence for humans using wood for fires is at Gesher Benot Ya'aqov in Israel, 790,000 years ago. However, concern over the impact that the burning of fossil fuels is potentially having on the climate has resulted in renewed interest in biofuels.

Difference Between Biofuel and Fossil Fuel The most obvious and the fundamental difference between biofuel and fossil fuel is that the first is a renewable energy source while the latter is a non-renewable energy source.However, before delving further into the difference between biofuel and fossil fuel, let us first look at each fuel separately. It takes millions of years to generate fossil fuel in the earth but regeneration of biofuel is a very short period. • Fossil fuel is a non-renewable energy source whereas biofuel is a renewable energy source.

Biofuel Bioethanol is an alcohol made by fermentation, mostly from carbohydrates produced in sugar or starch crops such as corn, sugarcane, or sweet sorghum. Cellulosic biomass, derived from non-food sources, such as trees and grasses, is also being developed as a feedstock for ethanol production.iogas is methane produced by the process of anaerobic digestion of organic material by anaerobes. It can be produced either from biodegradable waste materials or by the use of energy crops fed into anaerobic digesters to supplement gas yields. The solid byproduct, digestate, can be used as a biofuel or a fertilizer.
