Geothermal power in Indonesia is an increasingly significant source of renewable energy. As a result of its volcanic geology, it is often reported that Indonesia has 40% of the world's potential geothermal resources, estimated at 28,000 megawatts (MW).
With 2,356 MW of installed capacity as of year-end 2022, this puts Indonesia in second place in the world after the United States in utilizing geothermal power, superseding the Philippines. In 2007, geothermal energy represented 1.9% of the country's total energy supply and 3.7% of its electric power.
