Crash Course in geothermal heat pumps!

Found a website with some great information on geothermal energy! A lot of helpful graphs and visual aids. Just a snippet below, but you can view the full website at http://www.fossilfreedom.com/geothermal.html

"Studies show that approximately 70 percent of the energy used in a geothermal ground contact heat exchange heating and cooling system is renewable energy from the ground. The remainder is clean, electrical energy which is employed to concentrate heat and transport it from one location to another. In winter, the ground soaks up solar energy and provides a barrier to cold air. In summer, the ground heats up more slowly than the outside air.

Ground contact geothermal systems do the work that ordinarily requires two appliances, a furnace and an air conditioner. They can be located indoors because there's no need to exchange heat with the outdoor air. They're so quiet homeowners don't even realize they're on. They are also compact. Typically, they are up to six times less expensive to operate since they are far more efficient then any fossil fuel based system."
