(1) The amount of ocean energy contained in the total mass of ocean water is enormous, but the energy per unit volume, unit area and unit length is small. This means that if you want to get large amounts of energy, you need to get it from a large amount of seawater.
(2) Ocean energy is renewable. Ocean energy comes from solar radiation and gravitation between celestial bodies. As long as the sun, moon and other celestial bodies coexist with the earth, this energy will be regenerated and will be inexhaustible.
(3) Ocean energy can be divided into more stable and unstable energy sources. The most stable are the energy of temperature difference, the energy of salinity difference and the energy of ocean currents. Unstable energy is divided into two types: regular changes and irregular changes. Tidal energy and the energy of currentstides are unstable but change regularly. According to the changing laws of tidal currents, people make daily and hourly forecasts of tides and tides for various locations to predict the size and strength of tides at different times in the future. Tidal power plants and tidal power plants can organize power generation operations based on forecast tables. What is both unstable and irregular is the energy of the waves.
(4) Ocean energy is clean energy, meaning that once developed, ocean energy itself will have little impact on ocean pollution. environment.
Marine energy production is as follows:
1 Tidal energy production: use of tidal energy to produce electricity , that is to say cyclic energy. the rise and fall of sea water. The energy is converted into electrical energycudgel. The difference in water level is expressed in potential energy and the speed of the current is expressed in kinetic energy.
2. Wave power generation: Use the kinetic energy and potential energy contained in sea surface waves and convert them into electrical energy.
3. Thermoelectric power generation: Use the thermal energy caused by the temperature difference between the surface water mass and the deep ocean water mass and convert it into electrical energy.
4. Ocean Current Power Generation: Use the movement of ocean currents in the ocean to drive the generator's rotation and convert the kinetic energy of ocean currents into electrical energy.
