About this report
Electricity generation from geothermal sources increased an estimated 2% year-on-year in 2020, falling below average growth of the previous five years. Geothermal capacity additions averaged 500 MW per year in the last five years, with Turkey, Indonesia and Kenya responsible for most of this growth. These countries are expected to continue to lead, as they have abundant and untapped resource availability.
Nevertheless, geothermal technology is still not on track to reach the required Net Zero 13% generation increases per year over 2021-2030, corresponding to ~3.6 GW of average annual capacity additions. Policies to decrease costs and tackle challenges associated with predevelopment risks are needed to enlarge the deployment of geothermal resources for power generation.
