Renewable Energy is energy obtained from sources which are practically inexhaustible. Prominent examples include solar energy, wind energy, and geothermal energy. The table below lists some of the conversion technologies that are used to harness the energy from these resources .
|Renewable Resource||Energy Conversion Technology|
|Biomass, solid fuels||Combustion (direct-fired, cofiring with coal); Gasification/Pyrolysis|
|Biomass, gas and liquid fuels||Fuel Cells|
|Geothermal||Dry steam electric; Flash electric; Binary cycle electric; Direct use; Geothermal heat pumps|
|Solar||Photovoltaics (PV); Concentrating solar thermal electric (parabolic trough, parabolic trough, power tower); Thermal water heating; Absorption chilling|
|Water, Hydro||Hydroelectric turbines; Pumped hydro storage|
|Water, Ocean||Wave energy devices; Tidal/current energy turbines; Thermal energy conversion|
