!0 Clean Ways to Power the 21st Century

According to Ken Thar of Live Science, scientists are racing to perfect greener sources of energy to improve the environment and reduce dependence on oil and other fossil fuels. Some predict a hydrogen economy. Others say solar is the way to go. Wilder schemes involve sky-high wind turbines or antimatter engines. LiveScience explores the expectations, myths and realities of 10 top possibilities: solar, wind, coal, biomass (energy stored in organic matter), hydro-electricity, ocean thermal energy conversion, nuclear, hydrogen and oxygen fuel cells, and the controversial anti-matter energy.

Antimatter is the Bizarro twin of matter, made up of antiparticles that have the same mass as ordinary matter but with opposite atomic properties known as spin and charge. When the opposed particles meet, they annihilate each other and release tremendous amounts of energy as dictated by Einstein's famous equation, E=mc2.
