Abstract
Ocean energy is one of these renewable sources comprising a vast amount of the renewable energy source as it covers 70% of the earth. This paper focuses on the idea of getting benefitted by one of the largest sources of renewable energy source by absorbing its energy in the form of marine and tidal current energy, thermal energy, wave energy etc. This paper will also give us a perspective of how harvesting of the ocean energy would change the traditional energy production business with respect to economy, efficiency and its effect on nature.
