Why is hydropower a green energy source? It is because we are able to harness electrical power by converting water into electricity. The use of hydroelectric power or even hydroelectricity dates back to Ancient Greece and China when they installed waterwheels in rapidly flowing rivers to turn millstones and other equipment. Years later, this was used in the New World which is now known as North America...

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...
