This country has about 130 active volcanoes, more than any other. This gives it around 40 percent of the world’s geothermal potential. Indonesia could probably obtain up to 29 gigawatts of energy a year from geothermal heat. At present, less than 10 ­percent of this is used. Globally, geothermal capacity is expected to rise by about 30 percent by 2024, to 18 gigawatts.

Renewables as a proportion of electricity generated (2018): 17 %

Electricity consumption per capita (2018): 1.0 MWh
