Ocean energy has four distinctive characteristics, which are: 1. Ocean energy accounts for a large part of the total ocean water mass, and the energy possessed per unit volume, unit area and unit length is relatively small. This means that if you want to get a lot of energy, you need to get it from a lot of sea water.
2． Ocean energy is renewable. It does not need to burn coal or oil, but comes from solar radiation and universal gravitation between celestial bodies. As long as the sun, moon and other celestial bodies coexist with the earth, this energy will not be exhausted.
3. Ocean energy can be divided into more stable and unstable energy sources. The most stable energy sources include temperature difference energy, salinity difference energy, and ocean current energy. Energy instable is divided into two types, one that changes regularly and the other that changes irregularly. Tidal energy and tidal current energy are unstable but change regularly. In reality, people can compile daily and hourly tide forecasts for various locations based on the changing laws of tidal currents, and predict the size and strength of tidal currents that will occur in the future. Tidal power plants and tidal power plants can adjust power generation operations based on forecast tables. Wave energy is both unstable and irregular.
4. Ocean energy is a new type of clean energy. Its use to produce electricity does not consume fuel, does not produce waste, waste liquids or waste gases and does not require transportation. The development of marine energy will not produce new pollution,will have less impact on the environment than traditional energy development industries and has more advantages than disadvantages. We can say that it is the “blue power” with the greenest and most environmentally friendly ideas.
