What is Green Energy?

Green energy, or renewable energy, is any form of electricity that comes from natural resources such as sunlight and wind. Green power sources do not emit harmful pollutants into the air and are thus considered environmentally friendly. In contrast to fossil fuels like coal, which release carbon dioxide when burned for fuel, green power produces no emissions at all. The term "green" refers to plants or plant-derived materials used in the process of generating electric power.
