![]() Geothermal power plants consume less water on average over the lifetime energy output than most conventional electricity-generation technologies**. They use less land per gigawatt-hour (404 m 2) than comparable-capacity coal (3,642 m 2), wind (1,335 m 2), and solar photovoltaic (PV) power stations (3,237 m 2)*.Ĭlean-Modern closed-loop geothermal power plants emit no greenhouse gasses and have life cycle emissions four times lower than solar PV, and six to 20 times lower than natural gas. Small footprint-Geothermal power plants are compact. geothermal resources can be harnessed for power production without importing fuel. ![]() Renewable-The heat flowing from Earth’s interior is continually replenished by the decay of naturally occurring radioactive elements and will remain available for billions of years.īaseload-Geothermal power plants produce electricity consistently and can run essentially 24 hours per day/7 days per week, regardless of weather conditions.ĭomestic-U.S. In the United States, most geothermal reservoirs are in the western states. ![]() Wells, ranging from a few feet to several miles deep, can be drilled into underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications, including electricity generation, direct use, and heating and cooling. Geothermal resources are reservoirs of hot water that exist or are human made at varying temperatures and depths below the Earth's surface. Geothermal energy is heat energy from the earth-Geo (earth) + thermal (heat).
