Tidal energy is viewed as one of the most effective environmentally friendly power sources right now accessible. Tidal energy has a drawn out standpoint and can be projected more accurately than other environmentally friendly power sources like breeze, warm, sun based, etc. Flowing energy is both harmless to the ecosystem and inexhaustible. Tides are the ascent and fall of ocean levels delivered by the consolidated outcomes of the gravitational pulls of the sun and moon, as well as the revolution of the Earth. As technology advances, the use of electric and electronic devices grows tremendously, necessitating the production of more power sources in addition to current power sources to fulfill future needs. Furthermore, the method of transforming tidal energy into electrical energy differs depending on where you are. The technique used to capture energy from tides, on the other hand, is quite similar to that employed in regular hydroelectric power plants. This study discussed the one of the renewable source of energy called tidal energy. It is unique and suitable for future application as a power producing source due to these properties. There are numerous distinct kinds of tidal power plants across the globe, each with a particular tidal height.
