Geothermal energy is heat derived below the earth’s surface which can be harnessed to generate clean, renewable energy. This vital, clean energy resource supplies renewable power around the clock and emits little or no greenhouse gases -- all while requiring a small environmental footprint to develop.

The Energy Department is committed to responsibly developing, demonstrating, and deploying innovative technologies to support the continued expansion of the geothermal industry across the United States.
