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 ...
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. [1] Renewable energy replaces conventional fuels in four distinct areas: electricity generation, air and water heating/cooling, motor fuels, and rural ...

Although often confused with the relatively limited hydrothermal resource already commercialized to a large extent, HDR geothermal energy is very different. [3] Whereas hydrothermal energy production can exploit hot fluids already in place in Earth's crust, an HDR system (consisting of the pressurized HDR reservoir, the boreholes drilled from the surface, and the surface injection pumps and ...
Geothermal Energy is an underdeveloped energy resource and warrants further investigation and exploration. [2] According to the U.S. Department of Energy , Utah's geothermal capabilities alone, if fully developed, could provide 1/3 of the state's power needs.
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]

Geothermal activity is a group of natural heat transfer processes, occurring on Earth's surface, caused by the presence of excess heat in the subsurface of the affected area, usually caused by the presence of an igneous intrusion underground. [1]
