is thermal energy generated and stored in the Earth.
generation is cost effective, reliable, sustainable, and environmentally friendly method of producing electricity, but has historically been limited to areas where geothermal energy is available near the earth's surface, such as 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.
