10 Countries With the Most Geothermal Power

Geothermal energy is one of the most reliable forms of renewable energy, providing continuous electricity generation by harnessing heat from beneath the Earth's surface. Unlike solar and wind power, geothermal plants can operate around the clock, making them an important component of clean energy systems.

Several countries located along tectonic plate boundaries and volcanic regions have developed significant geothermal resources. The following are the ten countries with the largest installed geothermal power capacities in the world.

The United States leads the world in geothermal power generation with an installed capacity of 3,734 megawatts (MW). Most of its geothermal facilities are concentrated in western states, particularly California and Nevada, where abundant underground heat resources support large-scale electricity production.

Indonesia ranks second with 2,432 MW of geothermal capacity. Situated on the Pacific Ring of Fire, the country possesses some of the world's largest geothermal reserves. The Indonesian government continues to expand geothermal development to meet growing energy demand while reducing dependence on fossil fuels.

The Philippines holds third place with 1,937 MW. Geothermal energy plays a crucial role in the nation's electricity supply, helping strengthen energy security and reduce greenhouse gas emissions.

Turkey follows with 1,726 MW, reflecting rapid growth in geothermal investment over the past decade. The country has become a global leader in utilizing geothermal resources for both electricity generation and direct heating applications.

New Zealand, known for its volcanic landscapes, has developed 1,377 MW of geothermal capacity. Geothermal energy supplies a substantial share of the country's renewable electricity generation.

Mexico ranks sixth with 941 MW. The country's geothermal industry benefits from its location along active tectonic zones, particularly in regions such as Baja California and central Mexico.

Italy, the birthplace of commercial geothermal power generation, operates 834 MW of installed capacity. The country has a long history of geothermal development dating back to the early twentieth century.

Kenya has emerged as Africa's geothermal powerhouse with 817 MW. Geothermal energy is a cornerstone of Kenya's electricity system, providing reliable and affordable power.

Iceland, despite its relatively small population, has developed 779 MW of geothermal capacity. The nation's abundant volcanic activity enables extensive use of geothermal energy for electricity generation and district heating.

Rounding out the top ten is Japan with 618 MW. Although geothermal development faces challenges due to land-use restrictions and hot spring tourism concerns, the country continues to explore opportunities to expand this clean energy resource.

Together, these ten countries demonstrate the growing importance of geothermal power in supporting sustainable and low-carbon energy systems worldwide.
