Tidal power is a shape of hydropower that changes the energy of tide into electricity. The change in the water level between high tide and low tide produce tidal currents in coastal areas, which can be powerful sufficient to drive a turbine. Tidal power can be classified into two main types like kinetic energy and potential energy. By using kinetic energy the tidal stream will make to move the water to power turbines. The main advantage of this kinetic energy is the cost and the environmental crash will be less.
Barrages make use of the potential energy in the variation head between high and low tides. The main disadvantage of potential energy is the public transportation cost and environmental issues are very high. Tidal energy systems can have environmental crash on tidal sink because of concentrated tidal flow and deposit increase. Once the machine is constructed it costs nothing to make because waves are free. Tidal power does not pollute the environment because no dangerous gasses are place out into the air.
