We have the technology to do a lot of things and one of these is to tap the earth’s energy. This is exactly what we do when we decide to use geothermal which happens to be a green energy source. Geothermal energy is energy obtained by tapping heat from the earth itself. This comes from magma and the radioactive decay of uranium, thorium, and potassium. The downside to geothermal energy is the fact...

Is biomass a green energy source? According to experts, yes it is. In fact, it is one of the three main areas of bioenergy. But what is bioenergy? Well, it is a process by which organic material such as animal waste, plants and wood are used to generate electricity, produce heat and also aid in the production of biofuels. In the case of biomass, hot air or water is generated to produce electricity....

All cars are powered by gas. But with the volatility of crude oil prices and because it is not a renewable, something must be done before it is too late. Given that solar energy, a green energy source is used to power a community, you can also do this on a small scale by using the same principles to build your own car. But what do you need to make this work? A lot of things but the two most important...

Biofuels are also a green energy source. It has been around for a very long time and lately, people are beginning to take notice. Liquid biofuel which is the one used in cars is a natural and renewable domestic fuel that can only be used for diesel engines. This can be made from vegetable oils mostly soy and corn. The nice thing about it is that it contains no petroleum, is nontoxic and biodegradable. By...

Solar energy is a green energy source because it is a renewable and it does not cause any harm to the environment. This is achieved by converting the sun’s rays into electricity with the help of solar cells. There are three basic approaches how we can use this form of green energy source namely passive, active and by using photovoltaic cells. When we refer to passive solar energy, nothing is converted....
