Nuclear Fusion
a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.
Hydrogen Fuel Cell Vehicle
Fuel cell electric vehicles are powered by hydrogen. They are more efficient than conventional internal combustion engine vehicles and produce no waste
Solar Energy
radiant energy emitted by the sun.
Wind Energy
electrical energy obtained from harnessing the wind with windmills or wind turbines.
Hydroelectric energy
a form of energy that harnesses the power of water in motion such as water flowing over a waterfall to generate electricity.
Biomass

Gasohol
a mixture of gasoline and ethyl alcohol used as fuel in internal combustion engines.
Geothermal Energy
