Tidal energy is a growing renewable, clean, and environmentally friendly energy source that produces far fewer greenhouse gases than fossil fuels such as coal and oil. Moreover, its high predictability and elevated power output are also among the advantages of tidal energy.

Tidal power is a promising renewable energy source, but production costs, a limited number of suitable locations, and technological challenges hinder its expansion. April 12, 2022. Tidal power leverages the rise and fall of oceanic tides to capture potential or kinetic energy and convert it into other energy forms, often electricity.

Tidal energy is best captured in areas with high tidal ranges and strong currents. There are several ways to harness it. Tidal turbines can be installed in places with strong tidal activity, either floating or on the sea floor, individually or in arrays.

Because water is much more dense than air, tidal energy is more powerful than wind energy. Unlike wind, tides are predictable and stable . Where tidal generators are used, they produce a steady, reliable stream of electricity .
