Geothermal energy has been exploited as a source of heat and/or electric power for millennia. Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times and for space heating since Roman times. Geothermal power (generation of electricity from geothermal energy), has been used since the 20th ...
Geothermal power stations in the United States are located exclusively within the Western United States where geothermal energy potential is highest. The highest concentrations are located in the Mayacamas Mountains and Imperial Valley of California , as well as in Western Nevada .
The Sonoma Calpine 3 geothermal power station of The Geysers. Geothermal energy in the United States was first used for electric power production in 1960. The Geysers in Sonoma and Lake counties, California was developed into what is now the largest geothermal steam electrical plant in the world, at 1,517 megawatts. Other geothermal steam ...
Geothermal power is considered to be sustainable because the heat extraction is small compared to the Earth's heat content, but extraction must still be monitored to avoid local depletion. [7] Although geothermal sites are capable of providing heat for many decades, individual wells may cool down or run out of water.
The head of the designated agency is authorized, in consultation with the Secretary of the Treasury, to guarantee loans from lenders to qualified borrowers for the development of geothermal energy projects. As of 1980, the program was managed by the Assistant Secretary for Resource Applications at the Department of Energy (DOE). [3]
