IDT Energy New York asks: What is renewable energy?

As its name indicates, renewable energy is energy that is always available and cannot be “used up” as other sources of energy which are limited in quantity and will one day be exhausted. There is no way to “finish” energy received from the sun, wind or other energy sources based on the natural processes of the earth’s ecosystem.

Also known as “green energy” and “clean energy” , renewable energy tends to be much less polluting, eliminating the unwanted production of carbon dioxide and other harmful gasses which contribute to the dangerous “greenhouse effect” that scientists and environmentalists are so concerned about.
