"If you think geothermal energy is a substantial contributor to solving our problems, at least in your or my lifetime, you are totally clueless on this subject." Geothermal heat pumps can be used almost everywhere. And they can greatly cut heating and cooling bills. Geothermal systems are able to transfer heat to and from the ground with minimal use of electricity. When comparing a geothermal system to an ordinary system, a homeowner can save anywhere from 30% to 70% annually on utilities.[9] Even with the high initial costs of purchasing a geothermal system the payback period is relatively short, typically between three and five years.[10] Geothermal systems are environmentally friendly; they are a renewable energy source, non-polluting, and recognized as one of the most efficient heating and cooling systems on the market. en.wikipedia.org
