Renewable Energy Sources - Green Energy/Green Power for the Future

Renewable energy sources include the well-publicized solar energy and wind energy, but also include power sources like hydro-power, biofuels and solar parking lot lights geothermal energy. The difference in temperature between the upper layer of the ocean, which is heated by the sun, and the lower depths of the ocean can even be tapped as a renewable energy source. It is called ocean thermal energy conversion (OTEC). Use this guide to find information about all of these sources, as well as the green technology and innovation that allows us to harvest natural energy.
