What is Renewable Energy?


Renewable energy resources are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time. Renewable energy resources include biomass, hydropower, geothermal, solar, wind, ocean thermal, wave action, and tidal action. (The last three are not discussed in this brochure because there were no commercial operations using these resources in the United States in 2004.) In 1850, about 90% of the energy consumed in the United States was from renewable energy resources. Now the United States is heavily reliant on the non-renewable fossil fuels: coal, natural gas, and oil. In 2004, about 6% of all energy consumed and about 9% of total electricity production was from renewable energy resources.

Renewable Energy to Lessen the Load on the Front Lines

Using solar cells to recharge batteries in military equipment helps reduce excess weight for soldiers and improve energy efficiency.The scene is a familiar one from the nightly news: a U.S. soldier on patrol in a remote locale, outfitted in the latest high-tech gadgetry – radios, night vision goggles, navigation gear – devices that enhance mission capabilities and help keep the infantry safe.

While such electronic wizardry has become indispensible to the modern military, it also requires an ever growing amount of power to keep it all running.

Vortex Induced Vibrations Aquatic Clean Energy

http://www.vortexhydroenergy.com/ 

 A novel approach to extract energy from flowing water currents. It is unlike any other ocean energy or low-head hydropower concept. VIVACE is based on the extensively studied phenomenon of Vortex Induced Vibrations (VIV), which was first observed 500 years ago by Leonardo DaVinci in the form of “Aeolian Tones.”

Nanomaterial turns radiation directly into electricity

Abstract:
Materials that directly convert radiation into electricity could produce a new era of spacecraft and even Earth-based vehicles powered by high-powered nuclear batteries, say US researchers.  Electricity is usually made using nuclear power by heating steam to rotate turbines that generate electricity.
