Heat from the earth is an ever-present and mostly
untapped energy source. Today, geothermal plants
channel water deep underground to heat it sufficiently
to produce steam. This drives a steam turbine to produce
electricity. This type of process has significant environmental
and economic advantages over other sources
of electricity production. Only a small fraction of our
available geothermal resources are being used today.
A widening recognition of geothermal energy will
only lead to a greater implementation.
