The European marine energy industry describes the maritime area along France’s coastline as having “enormous energy use potential”. It believes that by 2050 it will be possible to install facilities there with a total capacity of 100GW that harness wave and ocean current energy. This could potentially meet 10% of Europe’s current electricity needs. Pending the rollout of a proper strategy at European level, the region of Brittany has asked France Énergies Marines (an institute that focuses on offshore renewable energies) and Cerema (centre for studies and expertise on risks, the environment, mobility and urban planning) to examine the potential of various wave energy converter devices at 21 regional ports. Several manufacturers have already expressed their interest in installing such devices at sites offering the greatest potential.
