Geothermal Energy barometer 2025

+0.3% The growth of primary energy production from geothermal energy in the EU27 between 2023 and 2024
According to EurObserv’ER, the contribution of geothermal energy within the European Union remained broadly stable between 2023 and 2024, with primary energy production steady at around 6.6 Mtoe. This renewable resource is mainly used for heating, less often for cooling, and for power generation, depending on aquifer temperatures. At present, the most dynamic sector is heating, driven by the development of new geothermal district heating networks, whose output rose by 4.6% between 2023 and 2024, reaching 993.4 ktoe. Conversely, geothermal electricity generation decreased slightly in 2024 (–0.9%), due to reduced output from Italian plants, which account for just over 90% of Europe’s geothermal power production.
