Geothermal energy is an umbrella term for various methods of extraction and storage of heat or cooling in rocks and soil. Geoenergy is predominantly used in Geothermal wells, Borehole stocks and Aquifers.
Individual wells to individual houses. Energy Factor 3-4 = it takes 1 kWh of electricity to produce 3-4 kWh of geothermal energy. Normal energy saving about 55-65 percent.
Several closely spaced drill holes that are connected in real estate. Energy Factor 4-6 = it takes 1 kWh of electricity to produce 4-6 kWh of geothermal energy. Normal energy saving about 75-85 percent.
Natural aquifers in rocks and soil. Typically used in large-scale projects such as district heating, hospitals and airports. Energy Factor 30-40.
