Announced for 2009 it will only come no doubt not in service by 2010

The development of renewable marine energies (ERM) appeared, at least until the stock market crash, have everything to please. It is in phase with the speech of the European Union on the "three 20 by 2020" (decrease of 20 of greenhouse gases, 20 energy efficiency and achieve 20 renewable energy). As with the Grenelle Act, which is 23 of renewable electricity production.

In addition, the maritime France well has by nature, with the second European capabilities for the hydrolien and the wind at sea, an excellent resource of houle and enormous potential of SEM (see Glossary) in tropical waters. A prospective study published by Ifremer this summer, the contribution of all those ERM could reach 17.2 terawatt hours (TWh) per year by 2020 (the equivalent of 3 nuclear power plants), including 12 TWh for the wind only offshore. Would be 7.7 of the total energy consumption: little to total, much in the light of the current situation.

But there are still Cup of political promises to the lips of a substantial production of marine electricity. With the wind, the more mature technique, only the project of the German Enertag at Veulettes-sur-Mer in Normandy (105 MW) has permissions. Announced for 2009, it will only come no doubt not in service by 2010.

If wind projects are many RTE 15 applications for the study of connection to the network, 4.100 MW of capacity , they faced a regulatory delay: Meedadt, load including ecology and Energy Ministry, has still not defined, as on land, areas of development of the wind (ECZ). And especially conflicts of use. Thus in Bay of Saint-Brieuc, Poweo group project would impede the operation of certain schools of scallops. And even those who make the effort of the consultation with fishermen, as the German company WPD to Normandy and the coast of the Vendée, were not party won. In the latter case, it is not the fishermen of the island of Yeu that block; the hostility comes from the vendéens elect, Philippe de Villiers at the top.

The problem of cohabitation is less in the operation of the energy of currents (current turbines), aimed at areas too brewed to be exploitable by fishing, but the line on the surface. It is in consultation with the local Committee of fisheries of Paimpol that EDF, which is interested in more constant than the wind energy, was able to launch this fall its project in the Héaux of Bréhat. It will be 4 to 10 gear of the Irish company OpenHydro Group, connected to the network in 2011. The breton consortium Sabella, who has tested a prototype in the Odet this year (), for its part still seeks funding to the industrial stage.

The challenge of the coming years is to be a French industrial chain of marine energy. The State, several regions (including the United Kingdom and the meeting) and companies such as EDF and DCNS signed on 17 October, the Initiative national partnership for the emergence of marine energy (Ipanema). This initiative, strong political sense, will however require a substantial financial contribution.
