Oceans, large lakes and bays are huge reservoirs of various useful and renewable energy recourses. World’s total estimated ocean energy reserves are about 130 TW. However, only a small fraction can be recovered economically. Ocean wave energy, Tidal energy, salinity gradient energy, energy from ocean currents, thermal energy, geothermal energy, chemical energy, and ocean biomass energy are the types of ocean energy. This paper gives an overview of various ocean energy technologies1
