What is it?:
the heat from the earth through water and rock found miles beneath the Earth’s surface.
How it is obtained:
Within 10’ of the Earth’s surface temperatures are constant within 50 -60 F. Using a geothermal heat pump, duct work and heat exchange system (a series of pipes buried into the ground), heat energy can be extracted from the earth. heat is removed from the heat exchange and into an indoor air system in the winter to heat a building. In the summer the pump removes heat from the indoor air thus cooling a building. The extracted heat can be used to make hot water.
Geothermal energy can be used to heat and cool buildings, and heat hot water. Wells can be drilled into underground reservoirs to generate electricity. Steam from hot water can be used to power a generator. Geothermal energy has also been used for greenhouses, drying crops, heating water at fish farms and pasteurizing milk.
Geothermal power plants do not have smokey emissions; they emit water vapor.
Halco is a Company in Madison County that provides geothermal systems.
Geothermal Energy is currently used to heat DECs Five Rivers Environmental Education
