What is Green Energy?
– Renewable Energy Basics
Green Energy is simply the use of energy produced with or from renewable sources. Renewable means that the source is not finite, such as coal, oil, natural gas, or uranium, and can never be depleted. This is different than non-renewable energy sources, which include fossil fuels, nuclear waste, and pollutants. Non-renewable sources will run out sometimes, while renewable ones can always be renewed.
One great example of renewable energy projects is solar energy. You may have heard of solar panels and wind generators. However, there are many other ways that you can use green energy in your everyday life.
Biogas has been called the world’s silent energy. It is created by bacteria through a process called electrolysis. When the bacteria breaks down sugars in food, they release a gas, called biogas, into the environment. The problem with using biogas as a renewable source for energy is the cost of production. Biogas has to be produced in such large quantities to be economically feasible, and it takes a long time to break down to a usable liquid form. Also, the quality of the biogas produced from conventional energy sources like coal and oil is not good and does not always come out at the same quality as what we expect from our drinking water.
Wind power can also be used as green energy. In some places where the wind is strong enough to produce more energy than what can be stored up in electric batteries, it can be used directly by installing turbines. Although this is one of the most environmentally-friendly forms of green energy sources, it can still have its disadvantages. First of all, because of the cost of setting up the turbines, it is not always practical. Also, because wind power is intermittent and not constantly available, it may not be cost-effective during extreme weather conditions.
One of the advantages of solar power is that it is very flexible and can be used in many different ways, both renewable and non-renewable. It can also be used on a large scale for commercial purposes. Another advantage of using solar power is that it produces power gradually, thereby being very reliable. Many homes run on solar power, even when there is no sun available. The biggest disadvantage of using solar power is that it is expensive when purchasing the necessary equipment and using it yourself.
Biofuels are those fuels obtained from organic materials like wood or animal dung. They can be used as replacements for petroleum or other non-renewable sources of energy, as they are believed to be cleaner than their alternative counterparts. However, biofuel consumption is only sustainable for a limited period of time before the fuel source is depleted. In addition, biofuel is a poor substitute for fossil fuels because it emits more carbon dioxide than it actually uses.
The third type of renewable energy is geothermal energy. Geothermal plants use ground source heat pumps to transfer the heat generated in the earth’s crust into a confined space. During cold times, the heat pump extracts heat from the earth’s interior and uses it to heat water. In hot weather, the heat pump extracts heat from the earth’s surface and uses it to heat the air. Unlike fossil fuels, geothermal sources do not deplete over time, so they are considered a sustainable form of energy. However, because they are still relatively new technology, they are not as available as the more established types of renewable energy.
Although it is expensive to set up geothermal plants, they have been a popular choice among homeowners and small-time developers. One of the biggest advantages of using geothermal energy is that it has no negative environmental impact whatsoever. Moreover, geothermal plants require very little maintenance, and they generate free electricity. There are many other examples of green energy sources that you can learn about, so be sure to look into them when you are researching your home options.
