Plan your energy use. Use the heating system only when necessary. Use the water heater in a way that it does not run the whole day. Plan ahead so you can shower and do the dishes while it is one and the switch it off to save power. Cook meals ahead of time on one day and saves energy by only using the stove and oven once or twice a week. Use timers to manage when your lights are needed. Automated home systems are making the management and planning of energy use very easy.

Unplug unused appliances. This really does make a difference in energy use and costs. When you are not using the microwave or your hair dryer or your laptop or your printer, unplug it. There are some appliances that have to stay on like the refrigerator, but non-essential appliances that are not used should be unplugged. This has been proven to save energy.

Make your own energy-saving devices. There are so many ideas from solar panels made from CDs to green roofs and mini wind turbines. Make use of some of these gadgets or activities to help reduce your energy use and impact on the planet. It can be a family activity and it will stimulate your creative side. Once you see these small and affordable devices make a change to your daily life you will wonder why you didn’t try it sooner.

Avoid using electrical appliances if you can. Some appliances like the oven and refrigerator are necessary. However, a clothes dryer uses a lot of energy and the sun can dry your clothes just as well and actually help avoid mould development. So, instead of shoving your washing into the dryer, rather let them dry in the sun. The same can work for dishwashers. If you don’t have a lot of dishes dirty at the same time, wait to use the dishwasher. Alternatively, you can wash small amounts of dirty dishes by hand instead of using the dishwasher. If you have a look at your daily electricity use, you will find other devices you can use less and swop for non-electrical options.

Dress warmer before you turn the heat on. Instead of just automatically going for the heat switch, try and put on another jersey or jacket and get a blanket. Saving energy is a good reason to cuddle with loved ones and keep each other warm. The same goes for cooling systems. Before you switch on the fan or air conditioning system, try other methods of cooling down. You can insulate your home and plant trees strategically to block the sun.

Incorporate renewable energy sources. If you can afford it and your property allows for it, install solar panels or wind turbines. These alternative energy sources will save you a lot of money and it will also reduce your use of fossil fuel energy. These sources can be expensive to install, but if you are able to do it, it is an investment. You will be very grateful in the coming years. For those who cannot yet afford it, don’t worry. The technology is improving constantly and soon everyone will be able to afford alternative energy sources and benefit from them. You can have a look at the options offered by 3D printing to start with small things.

Use eco-friendly products. Buy eco-friendly light bulbs for your home and office. They use much less energy than normal bulbs. Also, look at buying energy-efficient appliances when you need to buy new ones or upgrade. Most kitchen appliances and things like washing machines have eco-friendly counterparts.

Have your house inspected. You can do this yourself if you don’t want to hire someone. Inspect things like door and window frames. If you can see light or feel air coming through the cracks, you may be losing heat that is causing an increase in energy use to heat up the home. Also, have a look at your home’s insulation and roofing and see if it may need upgrading or repairs. Heaters and other appliances can also be inspected for condition. If any appliances become hot while in use, it may be a sign of bad wiring or a potential energy problem. You can check out any devices and appliances and ensure that they are functioning correctly and not using more energy than they should.

Automate your house. This is not an option for everyone, but if you can afford it, you will save a lot of money. Automation systems use monitors that sense the levels of heat and cold and adjust heating and cooling accordingly. You can also control these systems through your cell phone or mobile device. For example, if you forgot to switch off a light or the oven, you can send a message to the system and will switch the appliance off. These systems are also easy to connect to alternative energy sources like solar systems or wind turbines. Automated home systems also warn you when it picks up problems with appliances and energy use.

These are simple ways in which you can save energy and save yourself some money. Many of the options to go completely green are still costly, but soon they will be more affordable. Technology is improving daily and if you can make small changes, you will soon be able to integrate all your efforts. Try and work in some creativity to make the transition fun. You won’t regret making the change to go green.a

Advantages and Disadvantages of Solar Energy in the UK

Blog9 - Advantages and Disadvantages of Solar Energy in the UK

Solar energy is one of the renewable energy sources that scientists are working to harness more effectively. Renewable energy sources will become more and more important as our fossil fuel resources start to run out. Solar power has both advantages and disadvantages. At the moment, most scientists and environmentalists agree that the advantages outweigh the disadvantages and solar power will help reduce climate change and its negative impact on the planet.


Solar power has many advantages and as the technology around it keeps improving, it becomes more affordable and more practical.

Solar energy is:

…eco-friendly and clean. It does not require the use of dangerous or harmful elements to generate electricity. It also does not produce harmful chemicals or gases that pollute our air and harm our atmosphere.

…free energy. Once you have solar panels or another solar power device, your energy is free. You don’t need to pay anyone to generate or use your solar energy. Different countries work differently, but here you have free energy and you can even make money by selling your surplus energy to the grid. By using solar energy you will be saving money by reducing your energy bill drastically.

l1 - Advantages and Disadvantages of Solar Energy in the UK

…renewable. This means that we cannot run out of sunlight. It is a resource that we have everyday and that will not become exhausted. Free energy that will never go away – that is basically what solar energy is.

…low maintenance. Once your solar equipment is installed, the biggest job is done. Solar panels are good for about 20 to 25 years and require little to no maintenance. The only thing you will need to do is keep it clean. Cleaning it a few times a year is sufficient and that is the extent of maintenance.

…of value to your home. Installing solar panels increases the value of your house. If you are looking to sell in the near future, it may be a good plan to install a solar power system. A house with solar panels will be in demand and can sell for a good price.

…versatile. Solar panels are not only used to generate electricity. It is also used to warm water through solar water heaters. You can see these on roofs as well and they have a little tank attached to them. These solar water heaters further reduce your electricity usage. These heaters are very effective in replacing traditional electric heaters.

These advantages show that solar energy is the way to go. It is the best way to do your part in reducing your carbon footprint and it will save you a lot of money. You may even be able to go completely off the grid if your solar energy system generates enough electricity to serve your home. If you are looking to get yourself a solar energy system, now is the time. However, we know that most things also have disadvantages, so let’s have a look at the drawbacks.


Not everyone in the world is on the solar power support train yet. There are still some issues that need to be addressed and solved before solar energy will be seen assustainable. Now we look at why some people are still sceptical about the future of solar energy.

l2 - Advantages and Disadvantages of Solar Energy in the UK

Installing solar panels or a solar system is expensive. The initial costs involved with getting a system installed and running is very high. The installation requires panels, batteries, wiring, and more. A unit can cost anything between £3000 and £7000. You will make this cost back triple-fold in the energy savings, but it will take years. A solar system is an investment and if you plan to stay in your house for many years to come, you will reap the benefits.

You have to use it or lose it. Technology is still advancing, but at the moment you cannot store solar energy for later use through just a normal system. If you want to save solar energy for use when there isn’t light, you will need a solar battery. These batteries are big and expensive and may not be worth it. Alternatively, you can use the solar energy during the day and use grid energy at night. This will still reduce your power costs immensely.

Solar energy generation is dependent on weather conditions. People often think that the sun must shine for solar panels to work, but this is not completely correct. It only has to be light. However, when it is raining and snowing and things like that, the solar panels may be less effective. Strong, direct sunlight is the best way to get your solar energy. The effectiveness of a solar system will depend on where you live and how the weather conditions are. For some areas, it may really not be worth it.

A solar system can be quite extensive and take up space. Depending how much energy you want to generate, you may need more than one panel and a battery and everything else that goes with it. This system can take up a lot of space and may cause you some inconvenience.

Solar energy is great, but you should carefully consider the pros and cons of installing a solar system for your home. Technology is constantly improving and soon these panels and batteries will be smaller and less expensive. We never know what the future holds, but these issues may well be addressed in the near future to make solar energy much more efficient.

Based on these advantages and disadvantages, you should be able to make an informed decision on whether you can and want to make use of solar power in your home and business. The bottom line is that it will benefit you more than you may think. If you would like to know more about solar energy and its latest developments, have a look at our previous article here.

6 Advantages of Renewable Energy and Some Interesting Facts

Blog8 - 6 Advantages of Renewable Energy and Some Interesting Facts

Renewable energy is the new trend, the new way of doing things, and the necessary option to keep our world population in the light. In the last few decades, renewable energy and the sources we get it from became front page news. These energy sources are vital to the survival of coming generations. Renewable energy is basically energy generated through sources that renew itself and cannot become exhausted. Examples include solar energy, wind energy, and hydro energy.

Here are a few interesting facts RMEDTECH gathered on renewable energy:

Several countries have big renewable energy goals. Countries like the USA, China, the UK, and others all have energy goals they have to reach by 2020. The UK’s goal, for example, is to generate 25% of its total energy through renewable sources. These countries are working hard to meet these goals and do their part in saving the planet.

Sunlight can run the world’s electricity needs. If we were able to harness the power of the sun thoroughly, one hour of sunlight would be able to power the Earth for a year. Unfortunately, technology can thus far only harness a very small percentage of the power of the sun. However, technology keeps improving and soon we may be able to harness more and be able to power more households and businesses off the grid than is currently possible.

r2 - 6 Advantages of Renewable Energy and Some Interesting Facts

Renewable energy creates jobs. Unemployment is a big issue in many countries and renewable energy may be part of the solution. It is estimated that renewable energy can create approximately 3 times the job opportunities that the other sources we are currently using.

The future is 2050. It is estimated that by the year 2050, the largest amount of the world’s energy will be supplied by alternative or renewable energy sources. We’re not sure if that means that fossil fuel use will fall away completely or if it will just make out a much smaller percentage. Regardless, a world powered by renewable sources sounds like a great future.

Millions of people are already living off the grid. Statistics that were gathered in recent years have shown that millions of households across the world have already started making use of renewable sources of energy like solar power and wind power. This means that there is already a large number of people making a difference and embracing the benefits of alternative energy sources.

Wind turbines are strong. The UK is one of the leading countries when it comes to generating and using wind power. They have a massive number of wind turbines and a large percentage of their energy is wind energy. One wind turbine can produce enough energy to supply 1400 households with the necessary electricity.

It is interesting to learn how the world is changing. It is also great to remember back to how things were and look forward the new future that looks a lot greener and healthier. We look forward to what the future holds and the day when we all live off the grid.

r1 - 6 Advantages of Renewable Energy and Some Interesting Facts


From these facts, it is easy to see why renewable or sustainable energy is a hot topic and one that can change the world. For centuries, we have been relying on fossil fuels and more recently on nuclear power for our electricity needs. Well, now some of these resources are running out and they all have negative impacts on the environment and human health. This is where renewable energy sources come in.

Renewable energy sources will help us heal the planet and also help improve the health conditions caused by a polluted environment. It has all these great benefits based on the facts mentioned before:

Reliable – Despite many people saying that wind and solar power are unreliable, renewable sources can be very reliable. All that is necessary is a good infrastructure and maintenance and planning. If managed properly, wind and solar farms can generate enough power to run the world without a hitch. When weather conditions are not ideal, a neighbouring city can supply energy or energy will be stored and made available for use during poor weather conditions.

Eco-friendly – Everyone knows about climate change and global warming. It is caused by the use of fossil fuels. Fossil fuels are burned to give us electricity and during the process, it causes so much pollution that both the Earth and humans are getting sick. Wind, solar, and hydro power are eco-friendly energy sources that do not have any of these pollutant emissions.

Job creation – Renewable energy is a new and booming market. Solar and wind energy projects, farms, and companies have created hundreds of thousands of jobs in the last couple of years. This will continue as the small kinks are being sorted out and wind and solar energy become more reliable and accessible. Creating jobs is one of the best benefits because there are so many unemployed people.

Renewable – It’s there in the name. Renewable energy sources are impossible or unlikely to run out. Fossil fuels will very possibly run out and then we will no longer have electricity. This is why alternative fuel sources are so important. Wind and solar energy won’t run out and will give the planet energy for centuries to come. Renewable energy sources cannot be exhausted.

Economic stability – The war for coal and oil and other fossil fuels have made global energy prices and economies fluctuate a lot. The demand for fossil fuels has created many bad situations across the world. The prices are influenced by any number of things and it can be very expensive. With renewable energy sources, this is no longer a problem. Countries need not fight over resources to have what they need. Now the biggest cost involved is the installation and management.

Low maintenance – Renewable energy sources don’t need a lot of attention or maintenance. Wind, solar and hydro power farms will operate on their own without the need for constant attention. This means that power companies will make a profit, the population will receive energy at low prices, and maintenance costs will be a very small fraction of the costs.

Renewable energy truly is the way to the future and it will have so many great benefits. Being less dependent on fossil fuels will clean the air, make people healthier, and resolve many conflicts. Renewable energy is a much more affordable and healthy option.

5 Advantages of Rural Electrification and How the UK’s Wind Farms are Helping

Blog7 - 5 Advantages of Rural Electrification and How the UK’s Wind Farms are Helping

Rural electrification has many advantages. Those of us who live in urban areas use electricity everyday and in almost everything we do. Now, people are trying to make this possible for others living in rural and remote areas like Africa and the outskirts of large cities. Electrification means to bring them electricity. We take electricity and its advantages for granted, but for the people in rural areas, it would be a blessing.

The United Kingdom is making very good use of wind energy in the pursuit of their very big energy goalsand also to help with rural electrification. The UK is a very good location for generating wind energy and is the best location in Europe for this purpose. Since 2008, the UK has consistently increased their wind energy capacity and generation.

Rural electrification has these advantages:

1. It will reduce isolation

People in rural areas are often cut off from the rest of the world because they don’t have telephones or cell phones or any other type of communication devices. Electrification will make it possible to give them telecoms and connect them with larger cities. This is very beneficial and will help in case of an emergency or if they need assistance of some sort.

2. It will improve health care and quality of life

Electricity will make it possible to run a hospital that can care for the sick. Healthcare without electricity is a difficult thing. They will be able to have monitors and other important medical equipment to better take care of the health of their people. Better health means a better quality of life.

3. It will help farmers be more productive

Rural farms work with very little and will greatly benefit from electricity. Electricity will make it possible to run their farms better. They will be able to use timers, improve irrigation, and just generally improve their farming activities.

4. It will improve safety in the community

Not all rural areas are equally isolated or off the grid. However, rural electrification will make any area safer through outside lighting, safety signs, alarm systems, and even traffic lights. Electricity is what makes many of our homes and offices safe and it can do the same for people in rural areas.

5. It will give them light

s1 - 5 Advantages of Rural Electrification and How the UK’s Wind Farms are Helping

Far off areas get very dark and this does not allow for many activities. Electricity will bring light to these areas which mean that they will be able to study at night, work longer hours, carry water home without fear of tripping, cook dinner in light, etc. Most of the people use candles or kerosene lamps which hold a great fire hazard. Many people have died in fires caused by candles and lamps. Not only will rural electrification bring them light, it will also reduce the fire risk and make their homes safer.

Rural areas can be very isolated and the communities there have very different lifestyles than those of us living in urban areas where electricity is a given. Some people don’t believe that this process is good for these communities, but these advantages clearly show that electrification will benefit them and improve their quality of life.

RMEDTECH would like to share a few other interesting facts about the wind energy situation in the UK.

  1. Onshore wind power is a cheap energy source. When compared to other energy sources in the UK, onshore wind power is the best and cheapest option for the population to make use of.
  2. They already generate more wind power than fossil fuel power. In 2016, the UK had successfully generated more power through wind sources than they did with coal. This is a very impressive goal to reach.
  3. The UK is 6th in the world. Currently, the UK is 6th in the world when it comes to wind power. China is first and the USA is second. It is in 3rd position in Europe.
  4. The UK has a large number of turbines on their farms. By the end of August 2017, the UK sported a total of 7 837 wind turbines. These turbines are the onshore and offshore farms combined. The onshore capacity is almost double that of the offshore capacity which may be why onshore wind power is the cheapest energy option.
  5. British electricity suppliers must sell renewable source energy. It is required by law that electricity suppliers sell a certain amount of renewable energy. If they don’t comply, they get fined and have to pay a penalty.
  6. Wind power is the largest renewable source in the UK. This is probably clear by now, but the largest source of renewable electricity in the UK is wind power. Biomass and wind energy are the two top sources of renewable energy and the UK are making good use of these resources.
  7. The UK has the largest offshore wind farm. Part of its impressive number of wind turbines is located on the offshore wind farm. The UK passed Denmark in this race and now has the title for the largest farm. The farm is located near the Kent Coast and is called the London Array.
  8. Scotland is the preferred spot for onshore farms. Scotland offers many unpopulated and windy hills and this has become a popular place to start wind farms. The hills of the countryside with the windy conditions are ideal for setting up wind turbines.
  9. The UK residents support wind power. Surveys were done to measure how many people would support the different types of renewable energy. Wind power was way ahead of most alternative sources and wave energy was a short second. Nuclear, oil, and coal energy were unpopular options.

The UK is definitely making a difference when it comes to using renewable energy sources. Wind power has many advantages and despite the initial costs and the fact that residents may need to pay a little more for electricity now to save a lot later, wind power is a plausible and successful option.

Solar Power and 3D Printing

Blog6 - Solar Power and 3D Printing

Solar power is one of the most used alternative energy sources today. Despite this fact, it is still questioned as a sustainable alternative and its costs are a big drawback. However, 3D printing is changing the world in a speedy and very positive fashion. Let’s have a closer look at what 3D printing is and how it can make solar power an energy source of the future.

What is 3D Printing?

3D printing is a new way of creating solid 3D objects. 3D printers make use of different materials to print a 3D object according specific software designs or a programme. It might sound a bit futuristic, but it is a very real thing.


3D printing will lower production and selling costs because everything will be more cost-effective. Production will be more effective, cheaper materials can be used, fewer transport or shipping costs will be needed, and production costs will be much lower.


Production of solar cells is more efficient through 3D printing. The cells can be made thinner and to specific specifications. Production costs will be lower because there will be less waste and the process will go a lot faster. Production can also happen on-demand and won’t need to be made too long in advance. This means that there is no more wasting time and money.

d2 - Solar Power and 3D Printing


The materials used to make solar cells are complex and must have specific qualities. The 3D printer can make the manufacturing of these cells so much easier and make them more efficient. By using the exact materials in the correct amounts to create the PV cells, they will be much more efficient than the normal flat roof panels used today.


Because people across the world can have 3D printers, the location will not matter. No more need for importing or waiting weeks for solar panels. Now, you can send in an order and the company can make the cells on demand and you can have them within days. Not only does this make customer satisfaction so much easier, it also saves the company money on transportation and shipping costs.


3D printers make it possible to manufacture solar cells of smaller sizes and that weighs a lot less than the ones used at the moment. The materials used are lighter and you can specify the size you want. Soon, solar cells will be paper thin and much more effective than the first cells that were created.

3D printing opens so many doors and solves a lot of problems that people may have with solar power and the equipment that goes with it. 3D printing is definitely the future of renewable energy and it is taking solar power to a new level. We are extremely excited and cannot wait to have our first 3D printed solar PV cells.

What Type of Gadgets Has 3D Printing Brought to Solar Power Solutions?

Sunlight is one of the most powerful energy sources on the planet. This is why we are trying so hard to harness the energy of sunlight and use it as an alternative source to fossil fuels. Fossil fuel burning is the main source of our electricity today and it is making our planet sick. So, many people have tried to come up with ideas that will relieve the strain on fossil fuel electricity and also help the environment.

Here are a few gadgets and inventions that people have come up with for the use of solar energy.

Glass and sand prints – Markus Kayser is a guy who took to the desert and built a 3D printer that uses sunlight and sand. This printer does not work with electricity. Instead, it uses sunlight for power and sand as material and creates beautiful and practical objects. This is a great discovery because there is lots of sand and lots of sunlight available across the world.

Satellites – 3Dprinted satellites that beam energy to Earth – yes, that is possible. Scientists in Japan are developing an idea where they want to print satellites that would gather solar energy and then beam this energy through microwaves to a receiving device on Earth. If they can get this idea to work, we would have an unlimited source of solar power and the weather conditions won’t affect our energy source.

Solar trees – This is another invention making use of 3D printing and solar energy. The idea is to print trees that have solar panel leaves. These trees will effectively act like a solar farm, but they will look like trees. These solar panel leaves will be flexible and could possibly even use the wind to produce energy.

d1 - Solar Power and 3D Printing

Solar panel prints – 3D printing has made so many things easier and more cost-effective. Solar cell printing is one of these things. Solar cells can be printed onto a roll of plastic like you would print a poster. These panels can then be stuck to the walls on the outside of buildings or used to line lamp posts or sidewalks. The opportunities are endless.

People everywhere in the world are trying new things and finding new ways to make use of solar energy and other alternative power sources. These people are changing the world and will continue to do so. None of these ideas are too far-fetched or impossible and we expect to soon see and hear these things actually being used. The future of alternative and renewable energy is near and it is very bright.


Blog5 - How to Bring Sustainable Energy Sources to Your Home and the Influence of Open Source

Many people still think that renewable or sustainable energy options are only for those who can afford it. This is not true. There are many ways in which you can make your home more energy-efficient through things you can do yourself. The great thing about renewable energy is that it has two very big advantages. The first one is that you are helping the planet and the second one is that you are saving yourself money. Renewable energy can help reduce or completely eliminate your utility bills and save you a lot of money.

Here are RMEDTECH’s suggestions for generating renewable energy in your home and saving yourself some cash.

Solar ovens – If you would like to start out slow with the transition from fossil fuel power to renewable energy, a solar oven is a great option. You can build your own or buy one. An oven uses the heat from the sun to warm and cook food. This is great because you can have hot meals even when there are power outages. Electric ovens use a lot of electricity and these ovens will help you save some money.

Solar panels – This is one of the most common ways that home owners are making use of renewable energy. Solar panels are most often installed on roofs, but they can also be set up in the yard. The angle of your property and roof will play a role. Solar panels can have an expensive upfront cost, but the money you will save in the long run makes it all worth it. You can also look into solar shingles if you need to upgrade or replace your roof. These shingles actually become your roof tiles and you won’t need to install big solar panels.

Wind turbines – Solar panels are easier to get away with in residential areas than wind turbines. Wind turbines may not be allowed for zoning purpose. They make a lot of noise and they are quite big even if it’s a small one. However, if you have a large property or a farm, nothing should stand in your way. Wind power has the potential to generate all the power you need to run your household. The success will obviously depend on your location and how the wind is there.

Solar water heaters – These heaters can also be seen on many roofs in residential areas. They are also like solar panels but they don’t generate electricity. Instead, these solar heaters are used to warm up water that is then used in your home. Using a solar water heater is a lot more cost-effective than using an electrical heater. It is also a lot easier to install than solar panels. This is another great option to get you started on converting from electrical to renewable energy.

solar - How to Bring Sustainable Energy Sources to Your Home and the Influence of Open Source

These options have been available for years and have become more accessible and affordable for homeowners. Some of this equipment will cost you a lot to install initially, but it doesn’t compare to the amount of money you will be saving. There are smaller versions and gadgets that perform these functions and you can find many YouTube videos that tell you how to build them yourself. So, ease yourself into the transition. As soon as you start seeing results, you will get on the renewable energy train and never look back.

You can also look for open source designs and software to get you started with 3D printing renewable energy gadgets and equipment.


Open source refers to something that is created by an individual or a group and is available to the public at no cost. This most often refers to software that programmers design for specific purposes or functions. The Linux operating system is a good example. One guy started it, made it open source, and a whole lot of people have since changed it and added to it to make it better. In other words, open source means that the public can have access to something that other people ask money for.

So, what does open source have to do with renewable energy? Everything! There is more than one reason why the world is only slowly moving towards renewable energy sources. One of these reasons is the science behind harnessing new sources to generate electricity. However, a lot of progress has been made and solar and wind farms are up and running in countries across the world. The second reason is the high cost of implementing these alternative sources in our everyday lives.

Buying solar panels or finding the space and permission to set up a small wind or solar farm can be a mission. The costs involved are tremendous and are too much to carry for most individuals. This is where open source and 3D printing come in. Many people are making their designs and instructions for wind turbines and solar cells open source. This means that anyone who has a 3D printer or a bit of creativity, can take these designs and create his own equipment and machines.

Yes, it is not quite that simple, but it isn’t all that complicated. If you can find an investor or seed money from someone who also believes that your idea is viable and can be profitable, all you need is to manufacture the necessary equipment and get it running. If your farm of small-scale equipment is successful, you can work to involve others and make renewable energy an easy option that is available to everyone at affordable costs.

If you like the idea of taking the fight for the planet into your own hands, start looking online for open source designs for wind turbines, solar panels, and other renewable energy options. There are many examples of people who have successfully used 3D printing to create their own solar cells that work better than the expensive ones and wind turbines that are portable. Gather your friends and family and get everyone involved in doing your part on making renewable energy an option for everyone.

We would love to hear about your experiments and successes. If you have open source designs or if you have started a renewable energy project in your community, please let us know. Visit our CONTRIBUTE page for more information on sharing your story.

Rural Electrification: What it Is and Why It’s Necessary

Blog4 - Rural Electrification: What it Is and Why It’s Necessary

What is Rural Electrification?

Rural electrification refers to the process of bringing electricity to rural areas that are far away from electricity infrastructure and very remote. Those of us who use electricity everyday tend to take it for granted and we don’t always realise how much we rely on it. People in rural areas don’t just need electricity for everyday uses like lights and heat, but also for farming. People who live in rural areas are generally self-sustaining meaning they all farm their own crops to eat. It is also the way to barter or trade for other things they may need. The uses depend on how evolved the community is.

Which Areas are Targeted for Rural Electrification?

The focus for rural electrification projects is generally in African countries and the outskirts of developed countries. The purpose of electrification is to make life easier for people living in rural areas and help them to be able to sustain themselves better. By having electricity, they will be more capable of keeping food for longer, they will increase productivity on farms, they may be able to do work and other activities after dark because they will now have light, etc. The benefits are plentiful.

Some companies have developed 3D printed solar cells, wind turbines, and other products that will help people in rural areas to have access to electricity. Natural sources of energy are more useful in rural and remote areas because they are far away from the electricity grids and lines. Making use of natural energy sources like the sun and the wind, will not only help the people live better, but it will make them do so in an eco-friendly way. It’s a win-win situation.

k1 - Rural Electrification: What it Is and Why It’s Necessary

People in rural areas may not be as reliant on electricity and gadgets and technology that go with it, but they definitely have a use for it. If farmers could have access to computers, the internet, or even just videos that can educate them, they will be able to improve their farming techniques. If they had electricity to power stoves or other heating devices, they would need less wood and possibly help reduce deforestation in certain areas.

What are the Benefits of Rural Electrification?

There are many benefits and many reasons why rural electrification is a good idea. The best part of it is that the energy options won’t add to the climate change problem, but it will help people have a better quality of life. It should be quite clear that bringing electricity to rural and remote areas will be a good thing. As companies work to create gadgets or machines that will help make this process easier, everyone will soon have the benefit of electricity and its many uses.

What Types of Power are Used for Rural Electrification?

Rural electrification is the process of taking power to remote and rural areas that are off the grid. These areas are generally not near the electricity infrastructures that run urban areas which means that the best option for electricity is renewable energy sources. Companies have been trying to get power to these areas to help them have a better quality of life and also to help them farm better.

Types of Power

The best types of power for rural areas are renewable energy sources. This is because these areas are often too far away for electricity lines and infrastructure. The homes and buildings in these areas are also not necessarily ideal for installing electricity or electrical equipment. For this reason, renewable energy sources are used to electrify these remote areas.

The most common types of renewable energy that are used are solar, wind, and hydro power. Setting up solar panels and wind turbines in large areas are very effective and can power a whole community. Farmers make use of this electricity and also receive compensation for the use of their land. Solar and wind energy is the easiest and best power options. If the area is near running water, hydro power is also an option. The water would need to run for some distance and it would need to be consistent. If it is, turbines can be installed to generate hydro power.


The big question is how do these people run and maintain the equipment. People and companies involved in rural electrification go to install the equipment and also train locals to operate and maintain these devices. The devices are not complicated to operate and generally don’t require too much attention once they’re operational. Obviously, the company will always be available to help when needed. By training the local farmers and other individuals to install, run, and maintain the equipment, they are also creating jobs. This is just another advantage of rural electrification.

Environmental Impact of Rural Electrification

The great thing about rural electrification is that it hardly influences the environment. People who live in these remote areas already have a very small impact on the environment because they live off the grid and rural electrification doesn’t really change that. Because rural electrification projects generally use renewable energy sources to help the communities, they remain low-impact and do not contribute to greenhouse gas emissions.

Rural electrification is changing the lives of many people and helping them live better and healthier lives. It also has financial advantages for farmers and it helps with job creation. All and all it seems like a pretty good operation.

Blog3 - Amazing Benefits of 3D Printing and Its Impact on Renewable Energy


3D printing has been used successfully in creating jewellery, toys, and medical-related products like scalpels and dental moulds. It has even been used with food. When it comes to sustainable energy sources, 3D printing will again change everything. These printers make it possible to produce parts and gadgets of equipment that make it easier for people to make use of sustainable energy sources.

Let’s look at why 3D printing is such a huge thing:

It saves money – The cost of manufacturing products the traditional way with large machines is very high. 3D printing is making it possible to make these costs several times cheaper. You no longer need all the very expensive tools and machinery to build or produce something.

It reduces risk – Prototypes are created to test a product and see if everyone is happy with it and whether it does the job it is meant for. With 3D printing the risk of making a faulty prototype that costs a fortune is much lower. You can print a prototype, see it, feel it, use it, and then if it’s not 100%, you can tweak the design and print a new one within a matter of a day.

It can create any shape – 3D printers have an infinite number of shapes and sizes it can create. You can design holes that change direction or squiggly shapes that no other machine will be able to pull off. This opens up a whole new world for artists and designers.

j1 - Amazing Benefits of 3D Printing and Its Impact on Renewable Energy

It is eco-friendly – Not only can 3D printers help make renewable energy more accessible to the public, but it is also eco-friendly. It uses much less power than other large machines and tools and it also creates a lot less waste. In fact, there is almost no waste involved with 3D printing.

It makes better quality products – 3D printing allows for errors that are easier and cheaper to fix. When a product is manufactured in bulk and a mistake slips in, the whole batch is a loss. With 3D printing, these errors can be detected and fixed easily and without the loss of large amounts of money and time.

It can use different materials – As the 3D printer technology advances, it will be able to use more and more materials. The existing printers can already use metal, glass, wood, plastics, gold, silver, and ceramics.

All of these factors make 3D printing a great partner for renewable energy projects. There are already people building all sorts of gadgets to make sustainable energy more accessible.

Categories of Electricity Use and Different Alternative Energy Sources

Blog2 - Categories of Electricity Use and Different Alternative Energy Sources

We use electricity everyday and all day. There are very few activities that we perform daily that do not require electricity in some way. This is the way we live in the 21st century. No matter if you’re at work, at home, relaxing, or on vacation – we use electricity all the time.

RMEDTECHlooked into the areas where we use electricity everyday and there are three main areas: residential, commercial, and transportation.


Residential uses of electricity refer to everything we do at home. If you look at your day from the time you get up to the time you go to sleep, which activities at home require power? Water heating for showering and washing the dishes. Cooking food on a stove. The kettle for coffee, the toaster, the microwave oven, the fridge and freezer, and whichever other kitchen equipment you use. Your electric razor, your hair dryer, your cell phone charger, and your television. Your internet and computers and all the lights. Shocking, isn’t it? To realise how much we depend on electricity at home.

e1 - Categories of Electricity Use and Different Alternative Energy Sources

Residential use of electricity makes up almost half of the energy use in the world. Energy waste occurs a lot in the residential category. This is why calls to conserve energy and use as little as possible are so important. Our resources are running out. By conserving energy and using less electricity daily, you will also be saving yourself some money.


Commercial uses of electricity have to do with the energy we use at work. Obviously, different types of businesses use different amounts of energy. Factories and manufacturing companies will likely use more energy than a small office business. However, it is the responsibility of all to help conserve energy. The types of activities that use electricity include computers, copiers, telephones, the internet, projectors, coffee machines, lights, manufacturing equipment, etc.

It can be difficult to reduce energy use in a workplace especially if it may influence production. However, there are options and systems that can help businesses reduce their carbon footprint and also save themselves some energy costs.


The third category of energy use is transportation. Almost every type of transport depends on energy. All vehicles run on some sort of fuel that is energy. Trains, buses, personal cars, aeroplanes, and even tractors use fuel and contribute to greenhouse gas emission and energy use. We are all dependent on transportation to travel to work, to the gym, to school, to the doctor, and to the shops. We use transportation everyday.Many cities encourage carpooling, using public transport, and making use of fuel-less transport like bicycles and walking. If we all drive less and walk more, it will already make a difference.

These three areas of energy use make up the majority of the total energy or electricity consumption in the world. The use in each of these categories differ from city to city and country to country, but they all contribute. The only way to reduce the demand for energy is if everyone does their part. You can make changes to your home to be more energy-efficient and you can change transportation habits as well. It doesn’t matter how small you start, as long as you start saving energy.

Alternative Sources of Energy for Homes

Clearly, we as humans rely on electricity a lot and we will find it difficult to get through a day without it. To reduce the demand for fossil fuel energy and help the environment, homeowners can start looking at alternative sources of energy.

Since scientists picked up on the problem of climate change and global warming, the world has been looking for alternative fuel options. These options are called many different things: sustainable energy, alternative fuels, green electricity, etc. The basic idea of sustainable energy is to use sources that do not cause the environment harm and that is renewable or will not run out. Currently, most of the world’s power is generated through the burning of fossil fuels or by nuclear power. Both these sources cause major damage to our planet and also holds dangers for human health.So, sustainable energy sources have been studied and are being refined. Some of these options are already being used on large scale by countries, factories, and businesses and some are also being used on a smaller scale by home owners.

Solar Power – This is one of the energy options that are being used most widely for both private and larger use. Solar panels are placed on top of roofs or in gardens or fields. Solar farms are created in desserts and other areas where there is a lot of sunlight. Smaller solar panels are being used widely for home use.

Wind power– Wind turbines are used to harness the power of the wind and generate electricity. Some countries have built wind turbine farms to generate enough electricity to run parts of the country. The UK is having a lot of success with this type of sustainable energy source.

Water-related power sources – Water has been used to help generate electricity for centuries. There are different ways in which water is used for this purpose. You have hydro power, wave power and tidal power. Wave power works with the waves and many devices have been invented to make use of this, but they are still being refined. Tidal power makes use of the tides of the ocean to generate electricity and could be very successful in the UK if developed further.

Other sources that are being used on a more small-scale basis include geothermal energy, biomass energy, and landfill gas energy.

Some of these methods are still being developed as potential sources of sustainable energy. Some of them also have side effects that are not ideal, but these are generally less severe than the ones we are experiencing with fossil fuels and nuclear power. There is still a long way to go, but in a short time, sustainable energy will no longer be a dream, but a reality.

All About Wind Turbines and the Advantages of Wind Power

SAMPLE2 - All About Wind Turbines and the Advantages of Wind Power

Wind power is an alternative energy source that is being used successfully in some countries. There are still some obstacles to making wind power work and the use of wind turbines a sustainable option, but these issues are being addressed and have shown some promise. Low-wind condition countries cannot yet use these turbines successfully, but new technology has been invented to solve this problem. Visit the USEFUL LINKS page on RMEDTECH to learn more about this great technology.

Today, we are looking at wind power and turbines and discussing what they are and how they work.

How do Wind Turbines Work?

Wind turbines look like fans, but instead of creating wind through switching on the electricity, it uses wind to create electricity. Simply said, the natural wind that occurs on our planet makes the turbine propellers turn. The turning propellers turn the shaft that forms part of the turbine. The whole thing is connected to a generator that works only when the wind power turns the shaft. That is how wind power creates electricity.

Types of Wind Turbines

There are two main types of wind turbines in use at the moment. Other prototypes and models are also being developed to address the issue of using wind turbines in low-wind conditions. The two main types are:

Horizontal-axis: This type of turbine looks like a normal fan with three propellers mounted at the top of a pole or shaft. They look like modern-day windmills.

Vertical-axis: These turbines look a bit different and can be likened to an egg beater or eye-shaped design.

Locations for Wind Turbines

Wind turbines are more effective in areas where there is a lot of wind. Depending on the conditions, these turbines can be built on land or in oceans or lakes. Weather experts and scientists evaluate potential areas for wind farms to see whether the wind speed and frequency will be sufficient to justify installing wind turbines. In some areas and countries, wind turbines are not successful at all because there is not enough natural wind to turn the turbines.

Advantages of Wind Power

Wind power is one of the best options for renewable energy and it has many advantages. This type of energy has its limitations, but people across the world are working to solve the issues involved.Wind power generally works with wind turbines of some sort to generate electricity as discussed above. The wind is a renewable source that we cannot run out of. The one drawback of this energy is that it is dependent on weather patterns. Despite that, this is a great source of renewable energy that will help us save the planet. Countries like the UK and China are having great success with their onshore and offshore wind farms. Here is why wind power is great:

  1. It is a renewable source of energy. The wind cannot run out or become exhausted as a source. It is a naturally occurring thing that is caused by the sun heating up the atmosphere. So, unlike fossil fuels and nuclear energy, the wind will be a source of energy for as long as the sun shines.
  2. It doesn’t cause pollution. Wind power does not cause any damage to the planet in terms of pollution. It doesn’t have any types of emissions that are the result of generating electricity. According to studies, wind power can make a significant reduction in greenhouse gas emissions when it is used on a larger scale.
  3. It doesn’t need water to generate electricity. Most of the current mainstream sources of energy require water in its processes. Wind power requires no water in generating electricity. This is a very big advantage because water is becoming increasingly rare and all life on earth depends on water. So, the less water needed for the generation of electricity, the better.
  4. It is cost-effective. Wind power is an affordable alternative source of energy. The largest costs go into building wind farms, but once they’re up, the costs are minimal. Some wind farms charge a mere few cents per kilowatt-hour for wind power generated on the farm. Compared to other sources of energy, that is the cheapest you will ever get.
  5. It doesn’t require major tree removal. Most of the areas where the wind is ideal to harness are found in open spaces in rural areas. These areas are usually farmland which makes it very easy to set up a wind turbine or two. These turbines then supply electricity to the farms and they get paid for the use of their land by the companies that build the wind turbines and harness the energy. This is great for both parties. It is also ideal for rural areas where the electricity grids cannot reach.
  6. It creates jobs. Wind power, as with solar power, is a growing market and is also responsible for the creation of thousands of jobs. Job opportunities related to wind power are growing at a great speed and will continue to do so as it becomes a more prominent energy source.

t1 - All About Wind Turbines and the Advantages of Wind Power

Wind power is a good option for a sustainable energy source. However, there are still some things that need to be addressed before everyone in the world can benefit from it. It is very clear that despite some challenges, wind power is a very real and very advantageous type of energy. Its advantages are numerous and will definitely help with reducing the exhaustion of other natural resources.Currently, the UK is one of the countries that have had the most success with harnessing wind power and creating electricity.
