Geothermal Energy – Heating and Cooling
http://www.geothermalenergy.org/ – Geothermal Heating and cooling is the most energy-efficient way to maintain comfortable temperatures in homes and large buildings.
We all want to save money heating and cooling our house or office, right? The answer may literally be under your feet. Much of the heating and cooling can come from the ground, below the surface with something called a Geothermal Heat Pump. Below the frost line, about 10 feet down, the earth maintains a nearly constant temperature of 54 degrees. You can tap into this geothermal energy to provide heating in the winter and cooling in the summer.
