The waves in the ocean are mainly wind waves, and the energy of the wind comes from the sun, so wave energy is a good renewable energy. In addition, according to the survey results of the World Energy Commission, the available wave energy in the world is up to 2 billion kw, which is quite considerable. At the same time, wave energy also ensures its good exploitability due to the following advantages 1:
(1) Wave energy is a kind of mechanical energy, which is the best quality energy in ocean energy. At the same time, it also makes its energy conversion device relatively simple.
(2) Although the energy flow density of wave energy is low, it has a large reserve. For example, in the mid latitude area of 30 40 degree on the east coast of the Pacific Ocean and the Atlantic Ocean, the wave energy can reach 30 70kw / m, and even 100kW / m in some places, which can ensure the total amount of energy that can be developed and utilized.
(3) The maximum available wave energy in winter can effectively alleviate the problem of huge energy consumption in this season.
(4) Wave energy is the most widely distributed renewable energy in the ocean, so wave energy can become an energy source in remote areas of the sea.
