My Nonfiction: Renewable Energy
Renewable energy, unlimited clean power to carry the human race into the next century. Photovoltaic cells are the best of the alternative energy sources. They have the best longevity because they are a solid state device, meaning no moving parts. A solar panel generates power with no noise and no wear and tear. The only maintenance for photovoltaic's is to go out occasionally and wash the panel clean with a squeegee. If the world could embrace photovoltaic technology it would improve the standard of life for all of the Earths inhabitants.
