Ocean energy power generation is to use the energy contained in the ocean to generate electricity. The energy of the ocean includes the kinetic energy of seawater (including current energy, wave energy, etc.), the energy contained in the temperature difference between the surface seawater and the deep seawater, and the energy of tides (tidal power plants, ocean power plants).
Ocean energy usually refers to the renewable energy contained in the ocean, mainly including tidal energy, wave energy, ocean current energy, seawater temperature difference energy, seawater salinity difference energy, etc.
Ocean energy is rich in reserves, widely distributed, clean and pollution-free, but has low energy density and strong regionality, so development is difficult and has certain limitations. Wave power generation utilizes the kinetic energy of the waves moving up and down on the sea surface.
The heat in the ocean can improve the climate and can also induce warming of the land. Due to the uneven solar radiation, the temperature of the seawater varies from place to place, causing the seawater to flow in a directional manner, forming ocean currents. Using ocean currents can generate electricity like water power.
Tides are huge movements of seawater, and this kinetic energy can also be used to generate electricity. The total energy of the tides on the earth is 10 billion kilowatts, which can be used to generate electricity. Under the action of wind, sea water also generates wave kinetic energy. It is estimated that the wave energy of seawater under the blowing of winds of level 5 can reach 24,000 kilowatts for 1 km of coast. There also appears to be potential for harnessing wave energy. It can be seen that the use of ocean power generation to benefit mankind is completely expected.
