geothermal energy

1. Produced by using the heat below the earth’s surface. Geothermal heat pumps are necessary for residential use; for commercial use, power plants are built on the surface to convert geothermal energy into electricity. See also: Energy
2. Hot water or steam extracted from reservoirs beneath the Earth’s surface; can be used for heat pumps, water heating, or electricity generation. The term may also mean the use of near-constant underground temperatures by ground-source heat pumps to provide heating and cooling.
