Geothermal Energy

Geothermal energy derives from the immense thermal reservoir of the earth's interior. Heat from molten rock (magma) beneath the earth's crust or from natural radioactive decay transfers to rock and water closer to the surface. In certain regions of the earth, the hot waters are close enough to the surface to be commercially exploited in heating applications, or, in the case of high-grade steam reserves, in power generation.

 

A recent study by the U.S Environmental Protection Agency showed that geothermal systems generally have the lowest life-cycle cost of all heating & cooling systems available today.
