Tidal power harnesses the natural energy of tides to generate electricity using turbines. It consists of a turbine, generator, duct and removable cover anchored to the seafloor. Tidal power plants can be constructed by building dams or installing towers, with the largest dam-based plant in France. The best locations have strong, predictable tides and are in deep water away from coasts to avoid fishing and wildlife impacts. Tidal power has advantages of being clean, predictable energy without weather impacts, but disadvantages include limited resources, noise pollution effects on animals, and sediment damage risks to turbines.
