Geothermal Capacity by Country

Geothermal capacity by country measures installed geothermal power plant capacity for each country, in gigawatts (GW). The reported capacity is concentrated in a relatively small group of countries, reflecting the geographic distribution of geothermal resources suitable for power generation. The statistics are based on the U.S. Energy Information Administration's (EIA) International Energy Statistics. The table covers 31 countries, with 30 reported 2024 values, and includes data from 2019 to 2024. The world total stood at 15.37 GW in 2024, up from 15.05 GW in 2023.

The United States remained the largest geothermal capacity holder in 2024, but its lead over Indonesia was only 0.057 GW. The Philippines, Turkiye and New Zealand followed with 1.95 GW, 1.73 GW and 1.27 GW.

The United States accounted for about 17.5% of the world total in 2024. The top two together held about 34.7%, the top three about 47.4%, the top five about 67.0%, and the top ten about 92.7%.

New Zealand was the standout grower in 2024

New Zealand grew by 21.4%, adding 0.225 GW and recording the largest increase among reported country pairs. Turkiye (+2.5%) and Indonesia (+1.6%) also expanded, while the United States, the Philippines and Mexico changed by less than 0.1%. Kenya was the only declining country among the top ten, falling 4.6% from the previous year.

Geothermal capacity has changed only modestly since 2019

Reported world values were 14.10 GW in 2019, 14.43 GW in 2020, 14.42 GW in 2021, 14.64 GW in 2022, 15.05 GW in 2023 and 15.37 GW in 2024. Capacity ended about 9.0% above the 2019 level. Unlike wind and solar capacity, the global geothermal total changed only modestly over the six-year period, with an increase of 1.27 GW overall.

Most leading countries added little capacity

Geothermal power capacity tends to change more slowly than many other renewable technologies. Several of the largest countries recorded little or no change in 2024: the Philippines remained at 1.95 GW, Mexico at 1.00 GW, Iceland at 0.79 GW and Italy at 0.77 GW. New Zealand was the notable exception, increasing from 1.05 to 1.27 GW.

Methodology

The statistics are based on the U.S. Energy Information Administration's (EIA) International Energy Statistics. Values represent annual installed geothermal capacity in gigawatts (GW). Where no value is available, the cell is left empty. A value of 0 indicates that the source reports zero. The sum of the countries listed on this page may not equal the reported world total because the country-level data presented here do not necessarily represent the complete set of values used for the world total. This page covers geothermal capacity only; other sources and generation are reported separately in the source.
