About ThinkGeoEnergy

The global energy sector is in the middle of a dramatic transformation and transition to renewable energy. The rapid expansion of renewable energy deployment sees a focus on intermittent energy sources and electricity, often neglecting opportunities provided by other clean energy sources, such as geothermal energy. With its capability to provide not only clean and sustainable energy for power generation, geothermal energy particularly shines in its offer to the transition of the heating and cooling sector globally.

With market research, authoritative news and events, ThinkGeoEnergy is the leading information services provider for the global geothermal energy sector and the market it serves.

ThinkGeoEnergy 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. Since its inception in 2008, ThinkGeoEnergy has focused on geothermal power generation and large scale-direct use of hydrothermal resources. At the same time with new topics such as deep geothermal heat exchange systems, storage, mineral extraction from geothermal brine, we are adapting our coverage on new technological developments and advancements on a constant basis.

TGE Research

With our global coverage since 2008, we have created an extensive database of companies, geothermal power plants and projects in development. While publishing some of that research, such as our annual Global Top 10 Geothermal Power Countries, we are working mostly on desktop research for clients. The publication and sale of country and topic-specific reports has been on the agenda as well.


ThinkGeoEnergy has partnered with various conference organisers over the years, including national and international geothermal associations, private conference organisers and since 2016 together with our German partner Enerchange GmbH & Co.KG the IGC.events collaboration that established IGC Turkey, the largest annual international geothermal conference in the fastest growing geothermal market of the past 20 years, and IGC Invest Geothermal, an annual geothermal finance and investment forum. At the same time, ThinkGeoEnergy has organised webinars and related events online. With increased virtual event concepts due to the covid pandemic situation, we have also been engaging with partners on own concepts within and outside the industry.

International Editions

With the global nature of the geothermal energy industry, and language barriers to specific markets, we saw a niche to provide specific language versions of ThinkGeoEnergy and founded PiensaGeotermia.com our Spanish language service in 2012, and JeotermalHaberler our Turkish language service in 2016 (in partnership with Enerchange).
