Geothermal power (from the Greek roots geo , meaning earth,
and
therm , meaning heat) is energy generated by heat stored in
theearth, or the collection of absorbed heat derived from
underground
in the atmosphere and oceans.
Geothermal energy offers a number of advantages over
traditional
fossil fuel based sources, primarily that the heat source
requires nopurchase of fuel.
From an environmental standpoint, emissions of undesirable
substances are small.

Geothermal power plants are unaffected by changing weather
conditions. Geothermal power plants work continuously, day
and
night, making them base load power plants.
From an economic view, geothermal energy is extremely price
competitive in some areas and reduces reliance on fossil fuels
andtheir inherent price unpredictability. It also offers a degree
of
scalability: a large geothermal plant can power entire cities
while
smaller power plants can supply more remote sites such as
rural
villages.
