At the dawn of the second half of the decade, France is resolutely pursuing its energy transition. In the face of environmental, economic, and geopolitical challenges, the country is adapting its priorities to ensure a more sustainable, resilient, and competitive energy mix. By 2025, national energy production reflects both the continuity of major historical orientations and the emergence of new dynamics driven by innovation and climate imperatives.
Among the actors of this transformation, the French gas suppliers occupy a strategic position. By diversifying their offerings towards renewable energies, particularly biogas, they contribute to making the energy mix more environmentally friendly while responding to the growing demand for energy sobriety and sovereignty.
The French energy mix in transformation
Historically, France has built its energy model on two pillars: nuclear electricity and hydroelectricity. By 2025, these two sources remain dominant, but their relative weight is evolving. The energy transition policy implemented over several years aims to diversify the mix while reducing the share of fossil fuels.
Nuclear energy still represents about 65 to 67% of national electricity production. However, the maintenance of plants, the aging of the fleet, and public debates on extending their lifespan or developing new EPRs are changing the outlook. While nuclear remains a fundamental element of France’s low-carbon strategy, the relative share of nuclear energy is expected to gradually decrease in favor of renewables.
At the same time, renewable energies are gaining ground. By 2025, they will account for nearly 30% of electricity production, with a notable increase in onshore and offshore wind energy, photovoltaic solar, as well as biogas and biomass.
The rise of renewable gas
As France seeks to reduce its dependence on imported natural gas, particularly from Russia and Algeria, the development of renewable gas has become a national priority. Mainly derived from the methanization of agricultural waste, sewage sludge, or organic waste, biogas injected into distribution networks is rapidly expanding.
By 2025, several hundred methanization units are operational across the territory, producing 100% renewable and local gas. Gas suppliers are adapting to this new situation, offering “green” options to consumers concerned about their environmental impact. Companies like Ohm Énergie are part of this dynamic, providing gas offers that include an increasing share of biogas.
This transition also supports the circular economy and the local agricultural fabric while limiting greenhouse gas emissions.
Solar and wind: the pillars of tomorrow
Photovoltaic solar continues to experience strong growth. By 2025, installed capacity will exceed 22 GW, thanks to numerous installations on rooftops, parking lots, as well as ground projects on industrial or agricultural wastelands. More and more individuals are installing self-consumption panels, thus strengthening decentralized production.
Wind energy, on the other hand, reaches nearly 21 GW of cumulative capacity. Although land development sometimes faces local resistance, offshore wind is gradually taking over. The first operational offshore parks increase renewable production while limiting land-use conflicts on agricultural land.
These two sectors are now essential to achieving France’s climate goals, namely carbon neutrality by 2050.
Hydroelectricity: a historical cornerstone still performing well
With more than 25 GW of installed capacity, hydroelectricity remains the leading source of renewable energy in France. It has the advantage of being controllable, meaning it can be mobilized according to the needs of the grid, unlike intermittent energies like wind or solar.
By 2025, although the potential for new large dams is limited, the modernization of existing facilities allows for performance improvements. Small hydroelectric plants continue to develop in rural or mountainous areas.
The challenges of the energy transition
Despite notable advancements, several challenges remain to stabilize and secure energy production:
- Storage: The intermittency of renewable energies requires the massive deployment of storage solutions, such as batteries or green hydrogen.
- Network adaptation: The electrical grid must be modernized to accommodate decentralized and variable flows.
- Energy sobriety and efficiency: Reducing energy consumption remains a major lever. Public policies aim to encourage thermal renovation of housing, reduction of unnecessary consumption, and raising citizens’ awareness.
- Social acceptability: Renewable energy projects must better integrate local consultation and benefit-sharing issues.
A more resilient energy future
In summary, energy production in France in 2025 is undergoing significant transformation. The country is focusing on a diversified mix, balanced between nuclear, renewables, and low-carbon gas. The integration of new technologies, decentralization of production, and the increasing involvement of citizens are redefining the energy landscape.
The role of French gas suppliers is fully integrated into this dynamic. By facilitating access to greener, more local, and more controlled energy, they contribute to building a more sustainable energy future, in line with the environmental challenges of our time.
