France launches (finally) in geothermal energy

It is a local, renewable and stable energy. In addition, And yet it remains marginal. Meanwhile, The government wants to change the situation with an action plan in seven measures unveiled on July 28, 2025. Therefore, Objective: to make geothermal energy a real alternative to fossil fuels.

Geothermal energy: a commando mission for an under-exploited sector – France launches (finally) geothermal energy

On April 11. For example, 2025, an accelerated mission was launched by Prime Minister François Bayrou, in partnership with ADEME, the geological and mining research office (BRGM), local authorities, energy industrialists and professionals in the sector. Therefore, Objective ? Moreover, Identify the concrete levers to take off geothermal energy in France, in France as in overseas.
This collective work led to an updated national action plan, presented on July 28, 2025, with the first priority priority measures. These actions target both regulatory brakes, technical challenges and france launches (finally) geothermal energy financial obstacles.

In France, The heat represented in 2022 almost 45 % of the final energy consumption, but it remained 73 % of fossil origin. Geothermal energy, however, is renewable, local, pototable and little issuing greenhouse gases. It helps heat accommodation, industrial buildings, agriculture or urban networks … but today only provides 1 % of national heating.
French geological basins such as the Paris Basin, Alsace, the Lyon region or Aquitaine have strong geothermal potential. But for lack of massive investment and a stable frame, Development remains marginal.

Four times more geothermal heat by 2035

In the multi -year energy programming (PPE) presented in 2025. the ambition is clear: Multiply the production of geothermal heat by four by 2035. This would represent 15 to 18 TWh for surface geothermal energy and up to 10 TWh for deep geothermal energy.
Surface geothermal energy (depth <200 m, temperature <30 ° C) today provides france launches (finally) geothermal energy two thirds of French geothermal heat. But it is deep geothermal energy (up to 3. 000 m deep, between 30 ° C and 200 ° C) which conceals the highest potential for expansion, in particular via urban heat networks.

Presented in June 2025 during the days of geothermal energy. these first seven measures are aimed at:

• Simplify authorization procedures,
• Accelerate instruction times,
• Strengthen technical support,
• Mobilize existing financial tools,
• Improve knowledge of basements,
• Train more qualified professionals,
• et support innovation in the sector.

The follow -up of their implementation will start in the fall of 2025with a half -yearly assessment. Government’s ambition: to make geothermal energy a pillar of the French energy transition.
