Tidal energy is a renewable energy powered by the natural rise and fall of ocean tides and currents. Some of these technologies include turbines and paddles. Tidal energy is produced by the surge of ocean waters during the rise and fall of tides. Tidal energy is a renewable source of energy.

If we could capture just 0.1% of the ocean’s kinetic energy caused by tides, we could satisfy the current global energy demand 5 times over.
