1. Different meanings:
Tidal power generation can be divided into three forms: 1. Single and unidirectional bank; 2. Double and one-way banking; and bidirectional. At high tide or low tide, seawater flows in and out of the reservoir, driving the turbine generator to produce electricity.
The energy of a wave is proportional to the square of the height of the wave, the period of motion of the wave, and the width of the surface facing the wave. Wave energy is the most unstable energy source among ocean energy sources.
2. Different effects:
The development of new energy sources such as tidal energy can indirectly slow down the increase in CO2 content in the atmosphere. Tides are a global phenomenon of periodic changes in sea level due to the influence of the two gravitational sources of the Moon and the Sun.
Wave energy is generated by the wind which transfers energy to the ocean. It is essentially formed by absorbing wind energy. The rate of energy transfer is related to wind speed and the distance at which wind and water interact (i.e. wind area). When the mass of water moves relative to sea level, the waves have potential energy and the movement of water particles gives the waves kinetic energy.
Application:
Ocean tides contain enormous amounts of energy. During the rising tide, the rising sea water has large kinetic energy, and as the sea water level rises, the huge kinetic energy of the sea water is converted into potential energy; During the ebb process, the sea water moves away and the water level gradually decreases. , potential energy is converted into kinetic energy. The maximum value of the ampThe tidal range in the world is about 13-15 m, but generally speaking, an average tidal range greater than 3 m has practical application value.
