Green power is electricity generated from renewable sources. It includes solar, wind, geothermal, biomass, and small hydro. Renewable sources are more environmentally friendly than traditional electricity generation. Unlike fossil fuels they emit little or no air pollution and leave behind no radioactive waste like nuclear. Most importantly, they are naturally replenished by the earth and sun.

* Solar: Converting energy from the sun into electricity using photovoltaic panels and solar thermal plants.
* Wind: Harnessing the power of the wind using turbines (wind power is the fastest growing renewable energy technology).
* Geothermal: Use of steam that lies below the earth's surface to generate electricity.
* Biomass: Releasing solar energy stored in plants and organic matter by burning agricultural waste and other organic matter to generate power.
* Small Hydro: Use of flowing water to power electric turbines (small hydro plants are less than 30 megawatts in size).
