There are three main areas with geothermal potential in France in the northeastern tip of the country, as well as in the central region, and in the southeast.

While global geothermal resource estimates have been established mostly for the United States, Europe and Australia, the wider global potential is tremendous.

In Europe, the main deep geothermal resources are located in Turkey, Central Europe, France, and Italy (around the Larderello field). On the map below, they are red, pink and brown areas.

In the future, areas with lower potential (oranges) can be exploited, but their development will depend on drilling costs.

For France, these deep geothermal potentials are  more precisely in the  Alsace, Auvergne, Limousin, Languedoc-Roussillon, Midi-Pyrenees,  Provence Alpes Cote d’Azur,  Rhône- Alpes and Franche-Comté regions according to the studies of the Geological and Mining Research (BRGM).
