Geothermal Energy
Geothermal energy is the energy stored in the crust of the Earth.
There are several methods to make use of this heat. Most easily
it is utilized either by bringing the heat to surface for the circulating
water in the buildings
directly or indirectly or
by converting that heat to electricity. Heat pumps,
using compressors like in a refrigerator, is another
well known method that can heat a house at 50% or cool it
at 25% reduced costs.
