Geothermal Electricity

The earth's heat content is more than double the typical rate of electric use in the average household. Electricity generated from the earth requires high temperatures that can only be reached far underground. To create a geothermal system, a well is drilled up to 2 miles into the earth's surface. Once in place, a closed loop conduit containing water or antifreeze is inserted into the well to transfer the energy of the earth's heat into the conduit and vice versa. In the winter, heat is pumped from below the earth's surface into the geothermal system. In the summer, cold is pumped from the relatively cooler area below the earth's surface and into the home using the same system. Although initial drilling costs are higher than traditional heating and cooling system, geothermal heat pumps require little maintenance, have few mechanical components, and are virtually worry free over the 25 to 50 year lifetime of the heat pump.
