France: Lots of sun, lots of wind and a clear course to 2035
France is one of Europe’s largest electricity producers and is continuing to drive forward the decarbonisation of its electricity mix. In 2025, the French transmission system operator RTE estimated that 95.2% of electricity generation came from low-carbon sources such as nuclear power and renewable energies3 - an all-time high. Solar energy grew particularly strongly: In 2025, around 5.9 gigawatts were added in France; the installed photovoltaic output was around 30.4 gigawatts at the end of the year.3
France has strong wind resources in the north-west, particularly in Normandy and Brittany, and good conditions for solar energy in the south and Champagne. As a result, wind and solar complement each other structurally in the country.
