The Tidal power is a type of hydropower that captures the power of the tides to generate electricity and perhaps other sources of energy. Tidal power, while not widely been using presently, it has potential to deliver electricity in the upcoming years. Tidal energy is a type of gravitational hydropower that uses flow of water to accelerate a turbine as well as generate energy. Researchers have discussed the various types of tidal energy and also the performance of various researchers in this field in this article.
