The global geothermal power industry has seen steady growth from 2020 to 2023, with 32 countries operating geothermal power plants, totaling 16,318 MW of installed capacity across 198 fields and 673 power units. Flash type units account for 52.7% of the total capacity, followed by binary ORC units at 25.1%. The top countries in geothermal power generation are the US, Indonesia, the Philippines, and Türkiye, contributing 96,552 GWh of electricity, or 0.34% of global electricity generation. Geothermal energy contributes over 10% of total electricity generation in seven countries, including Kenya, Iceland, and El Salvador. Most geothermal fields are exploiting hydrothermal or conventional reservoirs, with an estimated 3700 production wells producing nearly 3 MWh per well annually. The industry is expected to continue growing, but global efforts to limit warming to 1.5°C may alter this trajectory. The first World Geothermal Congress (WGC) in 1995 established a tradition of compiling global geothermal data, with subsequent reports refined over time. In 2022, the IGA introduced new tables for geothermal data standardization, aiming to improve data collection and sharing. These tables were used for the WGC2023 report, which included data up to early 2024. The report highlights the evolution of geothermal capacity and generation from 1980 to 2023, showing a 7.7-fold increase in installed capacity and a 7.4-fold increase in generation. Geothermal energy now contributes 0.34% of global electricity generation and 0.87% of clean energy. Geothermal power is significant in several countries, with Kenya, Iceland, and El Salvador generating over 10% of their electricity from geothermal sources. The global average capacity factor for geothermal plants in 2021–2022 was 67.5%, indicating efficient performance. The top ten countries by installed capacity in 2020–2021, along with their net additions, are detailed in the report. The report also covers the geothermal status of various countries, including Australia, Austria, Belgium, Canada, Chile, China, Colombia, Costa Rica, Croatia, El Salvador, Ethiopia, and France, highlighting their geothermal potential, current projects, and future prospects. Overall, geothermal energy remains a key renewable resource, with significant potential for growth in the coming years.The global geothermal power industry has seen steady growth from 2020 to 2023, with 32 countries operating geothermal power plants, totaling 16,318 MW of installed capacity across 198 fields and 673 power units.
