Sea Wave Energy Overview of Current Technologiesand views

The proposal of new technologies capable of generating electrical energy from renewable energies has directed research resources on seas and oceans. Research in this field finds the future of renewable energy very promising, especially in areas where there are specific climatic and morphological conditions that have the characteristics to exploit large amounts of energy from the sea. In general, this type of energy includes six energy sources: waves, tidal range, tidal current, ocean current, ocean thermal energy conversion and salinity gradient. The purpose of this review is to list several wave energy, converter power plants and analyze their years of operation. In this research, we try to know how many wave energy converter power plants work on average and whether it is really necessary to use such technologies.
