Almost every renewable energy resource begins with the Sun. Wave power is a third conversion of solar energy. The Sun creates the temperature differential that produces wind, and wind, in turn, produces ocean waves. Inventor Alla Weinstein found a way to convert the up-and-down motion of waves into electricity.

Take a look at my short video on wave power to learn more.

While solar, wind and wave energy all originate with the Sun, the heat locked up in the Earth itself offers another huge potential energy resource. Historically, that “geothermal” power could be converted into electricity only in those rare locations where natural fissures allowed water to flow into deep hot rock and come to the surface at temperatures high enough to generate steam. Now an innovator in Alaska has developed the first low-temperature geothermal power plant, which United Technologies is commercializing for worldwide sale.

“Anything you can get out of a barrel of oil, you can get out of a pound of sugar with the right microbe.” So says Jack Newman of Amyris Biotechnologies, who is using genetically-modified yeast to brew gasoline.

Harnessing solar energy can be pricey, but that soon may change. One company aims to cut the price by a factor of 10 by printing cheap solar ink onto flexible film that could serve as your roofing material.
