A joint report from Oak Ridge National Laboratory and NREL, funded by the US Department of Energy's Geothermal Technologies Office, reveals that widespread deployment of geothermal heat pumps (GHPs) in 70% of US buildings by 2050 could cut electricity demand by 13%, avoiding the need for 24,500 miles of new grid transmission lines.

GHPs, or ground source heat pumps, operate efficiently, emit no emissions, and transfer heat to and from the ground. The study underscores significant savings in grid costs, CO2 emissions, and building energy consumption, supporting GHPs as a key strategy for decarbonising buildings while boosting the domestic industry and creating jobs.
