Energy is an untouched source of energy. There are two major ways we can use the energy of the ocean. One is Tidal energy and the other is Ocean Thermal Energy Conversion. Wave energy is converted to electricity in various ways. This includes installing oscillating water columns, oscillating bodies, and overtopping converters. Tidal energies can be harnessed with the help of tidal turbines and tidal barrages. There are multiple advantages to using the energy from the ocean. Energy is low cost, renewable, abundant, and clean.
