How does geothermal energy work

Geothermal energy has a unique role to play in providing clean energy across the entire United States. Geothermal energy has huge potential—from heating and cooling enabled by constant underground temperatures just tens of feet deep, to reliable and flexible electricity generation from heat found thousands of feet or even miles below the surface.

These geothermal resources can be found nationwide, are “always on,” and represent significant domestic energy potential to support the nation’s clean energy needs.

This page provides resources to learn what geothermal energy is and how it can be tapped for power generation, heating, and cooling.

It also shares how the Geothermal Technologies Office (GTO) and other U.S. Department of Energy (DOE) offices are advancing geothermal technologies.
