Are renewable marine energies tomorrow's energies?

Written by the main involved actors (DCNS, IFPEN and others within the French 'Mer Bretagne' pole), this article indicates the various technologies used to produce marine energy at sea (offshore wind energy, wave energy, current energy, tide energy, thermal energy, marine biomass, and salinity gradient power). It discusses the development status of each of these technologies. It outlines that they are still very expensive, but have an interesting economic and energetic potential
