Geothermal energy is renewable heat energy from deep in the earth. Heat is
brought to the near-surface by thermal conduction and by intrusion into the
earth's crust of molten magma originating from great depth. Ground water is
heated to form hydrothermal resources -- naturally occurring hot water and
steam. Use of hydrothermal energy is very economic.
