A geothermal heat pump for every home?


  • M. Catherine White


Witnesses representing government, industry, and education requested increased federal funding to explore and utilize geothermal resources at a House Subcommittee on Environment hearing July 30. Citing the minimal environmental impact, low cost, and abundance of geothermal energy, and the chance to cut dependence on fossil fuels, the witnesses discussed the geothermal heat pump (GHP)—one of the energy source's most promising applications, according to testimony. The GHP has the capacity to help utility companies manage increased demand for electricity, and its small scale—one to a home—makes it highly accessible.
