In 2024, marine energy capacity in France amounted to *** megawatts. France was ahead of most countries in the race to marine energy, although its marine power production decreased in the last few years. In 2014 and 2016, the marine energy capacity reached its peak with *** megawatts of maximum production capacity.
Ocean power capacity
Despite its rise, marine energy capacity still represents a small share of the total renewable capacity in France. In 2024, France could produce around 74** gigawatts of renewable electricity. Marine energy has known a worldwide ongoing development, especially after 2010. Indeed, global marine energy capacity doubled between 2010 and 2011. It grew slowly since then and amounted to *** megawatts in 2024.
Ocean energy
Ocean energy accounts for both marine energy and offshore wind energy. In 2024, the operational capacity of offshore wind turbines in France amounted to roughly *** gigawatts, while projects for **** gigawatts of offshore wind power were under construction. More recent technologies like sea thermal energy were still on the fringe of the industry.
