The total reserve of wind energy resources is huge and widely distributed, belongs to renewable clean energy, but the energy density is low and unstable. Tidal energy (tide) is the energy that is present in the periodic fluctuating movement of seawater. Because the tide is most confident and regular in various motions of seawater, and rises and falls to the shore, the tide is firstly recognized and utilized by people, and the utilization of the tide energy is the most mature in the utilization of various ocean energies. In the process of flood tide, the turbulent seawater has great kinetic energy, and the great kinetic energy of the seawater is converted into potential energy along with the rise of the seawater level; in the falling tide process, the seawater rushes away, the water level is gradually reduced, and the potential energy is converted into kinetic energy. Tidal motion is usually accompanied by the occurrence of sea wind, and the combination of the two to generate electricity can improve the energy utilization efficiency thereof.
