The production potential of offshore renewable energy meets the objectives of energy and climate policy at international and European level. Under French law, the necessary planning for the development of the offshore renewable energies is carried out within the framework of energy law. This situation, which was not entirely satisfactory in terms of participation and respect for the marine environment, has led to legal developments. In particular, the planning method chosen should be improved through the implementation of MSP. The purpose of this article is to present the planning of offshore renewable energies under French law and to analyze its relevance.
