Geothermal energy, which comes from the heat beneath our feet, is more vital than ever.
RENEWABLE – It supplies renewable power around the clock, emits little or no greenhouse gases, and has a small environmental footprint.
RELIABLE – Geothermal energy provides baseload power and delivers a high capacity factor—typically ~90%—meaning that geothermal power plants can operate at maximum capacity nearly all the time. This high capacity factor allows geothermal power generation to balance intermittent sources of energy like wind and solar, making it a critical part of the national renewable energy mix.

GTO Program Areas
Data, Modeling, and Analysis
GTO's Data, Modeling, and Analysis (DMA) program supports data compilation and collaboration needs by collecting, analyzing, and disseminating data related to geothermal energy.
GRID (Value of Geothermal to the Grid)
Geothermal Data Repository (GDR)
U.S. Energy Information Administration (EIA)
Enhanced Geothermal Systems
Enhanced geothermal systems (EGS), or human-made geothermal energy, holds the potential to power the equivalent of more than 65 million American homes and businesses. GTO's EGS program supports projects that guide EGS technologies towards commercial viability.
Frontier Observatory for Research in Geothermal Energy (FORGE)
Hydrothermal Resources
Hydrothermal resources, or conventional geothermal, can be harnessed to generate electricity. GTO’s Hydrothermal Resources program funds research, development, and demonstration projects to reduce the costs and risks of exploring and drilling for these resources.
Low Temperature and Coproduced Resources
GTO’s Low-Temperature and Coproduced Resources program focuses on improving the efficiency of low-temperature geothermal systems (lower than 300°F/150°C). Low temperature geothermal resources can meet many energy needs, from heating and cooling to industrial processes like paper drying, greenhouses, and even beer brewing.
