The green transition of the energy sector is a hot topic in France. This has led to the design of strategies and policy initiatives for several years. Globally, the objective is to support the production and consumption of fossil-free energies. The French energy system is characterised primarily by a largely decarbonised energy production on the territory. However, primary energy consumption remains dominated by fossil fuels. In the context of the green transition, France has chosen to opt for a carbon-neutral and sovereign system.
