Geothermal heat pumps (GHPs) have been proven capable of producing large reductions in energy use and peak demand in buildings. However GHPs have received little attention at the policy level as an important component of a national energy strategy. The scope of this brief study includes determining the status of global GHP markets and the status of the GHP industry and technology in the U.S. assembling previous estimates of GHP energy savings potential identifying key barriers to application of GHPs and identifying actions that could accelerate market adoption of GHPs. The findings are documented in this report along with conclusions and recommendations.
