Geothermal energy is a renewable energy source that comes from reservoirs of hot water beneath the Earth’s surface. With applications in several economics sectors—electricity, industry, and buildings—increased use of geothermal energy has the potential to decrease the use of fossil fuels and the resulting greenhouse gas emissions. This explainer provides an overview of traditional and next generation geothermal technologies and how they work, the benefits of geothermal energy use, the challenges to increased deployment, and the policy landscape for geothermal energy in the United States.
