The U.S. geothermal energy market was valued at USD 2.27 billion in 2024 and is projected to grow at a CAGR of 3.3% from 2025 through 2034, reaching an estimated USD 3.15 billion in 2034. Steady capacity additions, growing federal and state policy support for clean energy, improving subsurface characterization technologies, and expanding direct-use applications are underpinning this growth. However, the market’s moderate pace reflects high upfront capital costs, permitting and grid-integration complexities, and site-specific resource constraints that limit rapid expansion compared with other renewables.
Market overview & dynamics
Geothermal energy in the United States includes electricity generation from high-temperature hydrothermal resources, enhanced geothermal systems (EGS), and an increasing set of direct-use and ground-source heat pump (GSHP) applications for heating and cooling. Utility-scale geothermal plants deliver baseload power contribution, valued for reliability and capacity factor, while direct-use applications—district heating, industrial process heat, greenhouse heating—and residential/commercial GSHP systems diversify the market.
The market value reported for 2024 reflects equipment, project development, installation, and services across the value chain: exploration and drilling, resource assessment, turbines and generators, heat exchangers, balance-of-plant equipment, and operations & maintenance. The modest 3.3% CAGR to 2034 indicates gradual commercialization of EGS pilots, incremental additions of new hydrothermal projects, and steady growth in heating applications and heat-pump deployments rather than explosive capacity buildouts.

Regional analysis (U.S.)
Geothermal resource distribution shapes regional market dynamics:
- Western U.S. (California, Nevada, Oregon, Idaho, Utah) — The epicenter for utility-scale hydrothermal power and the majority of installed geothermal capacity. Nevada and California lead in new project pipelines and exploration activity. High-temperature resources and existing grid interconnections favor power generation projects here.
- Intermountain & Rocky Mountain states — Opportunities for both utility projects and direct-use heating in industrial and agricultural applications, especially where local industry can benefit from low-cost thermal energy.
- Midwest & Northeast — Limited conventional geothermal power potential but strong growth prospects for GSHP systems for residential and commercial heating and cooling, driven by energy-efficiency programs and incentive schemes.
- Southeast — Emerging market for ground-source heat pumps; direct-use industrial applications could grow with targeted policy support.
Regional growth will therefore be two-fold: continued utility-scale activity concentrated in the West, and widespread heat-pump/direct-use deployment nationwide.
