This online resource delivers business-to-business news with a focus on development, technology, finance, and related topics, paired with market analysis and events informing and connecting players in the international geothermal energy market.[1]


Geothermal-DHC is a European research network addressing the inclusion of geothermal energy in decarbonized heating and cooling grids across Europe. The Geothermal-DHC website includes a Literature Web Database and links to recent global geothermal-related news.

European Geothermal Energy Council (EGEC)

EGEC, the European Geothermal Energy Council, is a non-profit international organization founded in 1998 to promote the European geothermal industry and enable its development worldwide by shaping policy, improving business condition, and driving more R&D. EGEC is comprised of over 120 members from 28 countries, including developers, equipment manufacturers, electricity providers, national associations, consultants, research centers, geological surveys, and public authorities.[2] In June 2022, EGEC released a market report that provides an in-depth assessment of the geothermal industry's evolution during the year 2021. The market Key Findings are publicly available.

International Geothermal Association

The International Geothermal Association (IGA) is a non-political, non-profit, non-governmental organization that supports and promotes the sustainable utilization and development of geothermal energy resources. IGA represents the global geothermal energy industry, with more than 4,000 members in over 65 countries, currently representing 36 national geothermal associations and groups, as well as industry and institutions. IGA promotes the utilization and development of geothermal energy resources through education, research, collaboration, and social awareness. [3]

In January 2021, IGA built a framework for geothermal data standards and methods to improve data collection, and update the World Geothermal Congress (WGC) reporting. Two groups of experts were formed: 1) for geothermal power generation, and 2) for geothermal heating and cooling. Each expert group had two sets of activities, categorized broadly as reviewing data standards and data management/analysis. In November 2021 the work of the IGA experts was completed. See Geothermal Data Standards for the updated heating & cooling dataset and results of the IGA Heat Expert Group.[4]

Global Geothermal Alliance

The Global Geothermal Alliance (GGA), supported and coordinated by the International Renewable Energy Agency (IRENA), serves as a platform for dialogue, cooperation, and coordinated action between the geothermal industry, policy makers, and stakeholders worldwide.
