Global Geothermal Energy Market Size Study & Forecast, by Type (Binary Cycle, Flash, Dry Steam) and Application (Industrial, Commercial, Residential, Others) and Regional Forecasts 2022-2032

The Global Geothermal Energy Market was valued at approximately USD 70.62 billion in 2024 and is projected to expand at a steady CAGR of 6.61% during the forecast period from 2025 to 2035, building upon historical data from 2023 and 2024. Geothermal energy, derived from the Earth’s internal heat, represents one of the most reliable and consistent renewable power sources available today. Unlike intermittent renewables, it delivers baseload power with minimal carbon footprint, making it an increasingly strategic asset in national energy portfolios. Rising pressure to decarbonize power generation, coupled with long-term cost stability and energy security concerns, is steadily pulling investments toward geothermal infrastructure across both developed and emerging economies.

Momentum in the market is being stirred up by advancements in drilling technologies, enhanced geothermal systems (EGS), and improved reservoir management techniques that allow developers to tap into deeper and previously uneconomical heat resources. Governments are rolling out supportive policies, feed-in tariffs, and funding mechanisms to crowd in private capital and scale projects faster. At the same time, industries with high and continuous heat demand are turning to geothermal solutions to hedge against fossil fuel volatility. However, high upfront exploration costs and geological uncertainty continue to act as friction points, particularly in regions where subsurface data is limited or regulatory frameworks are still evolving.

The industrial application segment is expected to dominate the geothermal energy market, underpinned by the sector’s growing appetite for stable, low-emission heat and power. Energy-intensive industries such as food processing, pulp and paper, chemicals, and mining are increasingly leaning into geothermal systems to decarbonize operations while locking in predictable energy costs. As carbon pricing mechanisms tighten and sustainability targets become more stringent, industrial users are scaling up geothermal adoption, positioning this segment as the primary demand driver over the long term.

From a revenue perspective, flash steam technology currently leads the market, accounting for the largest share of commercial geothermal installations worldwide. Flash systems are particularly effective in high-temperature reservoirs and benefit from proven operational reliability and mature project economics. While binary cycle plants are gaining momentum due to their ability to operate at lower temperatures and in environmentally sensitive areas, flash technology continues to command revenue leadership thanks to its deployment in large-scale power generation projects. This dynamic underscores a market where innovation is broadening participation without displacing established revenue pillars.

The geothermal energy landscape varies notably across regions. North America remains a frontrunner, supported by vast geothermal resources, favorable regulatory structures, and long-standing operational expertise, particularly in the western United States. Europe continues to scale capacity through district heating projects and deep geothermal exploration aligned with its decarbonization agenda. Asia Pacific is emerging as the fastest-growing region, driven by rising electricity demand, government-backed renewable energy programs, and geothermal-rich geographies in countries such as Indonesia, Japan, and the Philippines, where geothermal plays a pivotal role in energy diversification.
