**Home Heat Pumps**
[] Heat pumps move heat from one place to another - from outside to inside a home, for example. That's why they're called "heat pumps." All heat pumps have an outdoor unit (called a condenser) and an indoor unit (an evaporator coil). Studies show that approximately 70 percent of the energy used in a geothermal heat pump system is renewable energy from the ground. 95 percent of all geothermal heat pump owners would recommend a similar system to their friends and family.

5,000-1,000,000 years energy window for plant to function Currently in US 2,850 Mw are being produced: 2% Utah, 6% Cali, 10% Nevada, (Western states, Alaska and Hawaii) For every kilometer below the earth's surface, temperature rises 17-30 degrees C. Federal subsidies provide an important source of incentives for consumers to adopt the technology since estimates suggest marginal costs are up to 30% lower than traditional coal
 * Geothermal energy is cost competitive to coal without the detrimental effects.**



[] A geothermal heat pump system averages about $5,000 per ton of capacity. A three-ton unit, at a cost of roughly $15,000, works for a typical residence.

Albert Geothermal use began with the use of caves by cavemen. The Pubelo Indians built villages into the side of rock faces to reduce temperature in the hot desert sun. Early in the 1900's Italians where sucessful in using geothermal heat to generate electrical power. In the Early 1970's research began anew in the large scale of production of electricity in thesouth western states of the United States Current available useage in the south western states equals 2850 megawatts
