Geothermal heat pumps (GHPs), also referred to as ground-source heat pumps or Geo-exchange, have been proven capable of producing large reductions in energy use and associated carbon emissions for space conditioning and water heating in buildings. However, the current adoption rate of GHPs in the United States is still low, and GHPs receive little attention from either the public or policy makers. This report gives an overview of the status of GHP technology and its application in the United States, cost and performance of the state-of-the art GHP systems, barriers preventing wider adoption, and technologies under development that have potential to help overcome these barriers.
