The United States is currently the largest producer of geothermal energy in the world, leading in total installed geothermal power capacity and overall electricity generation from geothermal sources.

Quick Scoop 🌋

  • The United States has the highest installed geothermal power capacity, at around 3,900–4,000 MW as of late 2024–early 2025.
  • Major geothermal fields are located in western states like California and Nevada, where tectonic and volcanic activity provide strong heat resources.
  • Other big geothermal producers include Indonesia and the Philippines, but they still trail the U.S. in total capacity and production.

So if you’re asking “what country is the largest producer of geothermal energy?” , the answer—at least as of the most recent global data—is the United States.
