Geothermal Energy
In this section we will explore geothermal energy systems.  This includes high temperature systems which pull energy directly from the earth's core as well as low temperature systems which leverage the difference between air temperature and the temperature of the earth.

Energy Star Rated Geothermal Heat Pumps

Residential geothermal heat pumps are rated as to their efficiency and energy usage by the Environmental Protection Agency through its Energy Star ratings program. Earning the Energy Star certification means products meet strict energy efficiency guidelines set by the EPA and the Department of Energy. Energy Star qualified geothermal heat pumps use about 30% less energy than a standard heat pump. They are also quieter than conventional systems. Remember, saving energy prevents pollution. By choosing Energy Star and taking steps to optimize the performance of your heating and cooling equipment, you are helping to prevent global warming and promoting cleaner air while enhancing the comfort of your home. You may also be interested to know: Though these products can be more expensive to purchase up front, the cost difference will be paid back over time through lower energy bills.

The Air Conditioning Contractors of America (ACCA) online Contractor Locator includes a special designation to identify contractors who sell and are knowledgeable about Energy Star qualified HVAC equipment. ACCA is a non-profit association whose goal is to help the best Heating, Ventilation, Air-conditioning and Refrigeration (HVACR) contractors serve their customers.

The chart below provides the current list of Energy Star rated geothermal heat pumps:
