Where Does Renewable Energy Come From?
Wind Energy
Wind energy costs about the same as electricity from new coal- and gas-fired power plants. And it's pollution-free.
Solar Energy
Inexhaustible and cheaper than ever, solar energy now powers everything from portable radios to homes, stores and neighborhoods.
Biomass Energy and Cellulosic Ethanol
Plant materials, such as wood, corn, and soy, account for nearly half the renewable energy in America -- but it's not always sustainable.
Biogas Energy
Farmers can reduce pollution and generate their own heat and electricity by converting animal waste into a clean-burning gas.
Geothermal Energy
Reservoirs of steam and hot water beneath the earth's surface hold enormous potential as a renewable energy resource.
Hydropower
Energy from moving water is the largest source of renewable electricity in the United States. While water is a renewable resource, rivers themselves are not.
Offshore Wind, Wave, and Tidal Energy
Offshore renewable energy holds great promise, and can be developed in a way that protects our ocean resources.
