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....

Wouldn’t it be great if we can produce our own green energy source? If we can do that, we don’t have to pay electrical bills or gasoline anymore for our cars. While we can buy some of the equipment, the rest will have to be done on our own. Take solar or wind energy for example. We already know how to harness and make it. If you want to make one, do some research online and then set up the system...
