Geothermal, Page 2

Geothermal energy is thermal energy (heat) generated and stored in the Earth. The Geothermal energy of the Earth’s crust originates mostly from radioactive decay of minerals and from the original formation of the planet.
Geothermal power is cost effective, reliable, sustainable, and environmentally friendly,[5] but has historically been limited to areas near tectonic plate boundaries. Recent technological advances have dramatically expanded the range and size of viable resources, especially for applications such as home heating, opening a potential for widespread exploitation. Geothermal wells release greenhouse gases trapped deep within the earth, but these emissions are much lower per energy unit than those of fossil fuels. As a result, geothermal power has the potential to help mitigate global warming if widely deployed in place of fossil fuels. (Wikipedia)
