*Heat pump projects are managed by the Building Technologies Program because the U.S. Department of Energy classifies geothermal heat pumps as a technology that makes buildings more energy efficient, productive, and affordable. The focus of the Geothermal Technologies Program is electricity production; to research, develop, and validate cost-competitive technologies and tools to accelerate the growth of geothermal energy.

GTP is also supported by staff at several DOE National Laboratories.
