Pros and Cons of Tidal Power

Summary of tidal energy: As the energy crisis continues, the tidal energy gradually becomes prominent. There are many countries using unlimited infinite tidal energy, using a combination of dams, fencing and turbines. Due to the gravity of the moon, the tide of the day is very predictable and can be used very effectively. As companies compete for coastal rights, the spread of this energy is expanding.

As the global energy crisis progresses, renewable energy sources such as tidal energy are being explored. The tides of rising and descending of the sea surface are caused by the attraction of the sun and the moon and the rotation of the earth. Tidal energy is generated by converting the gravitational potential energy of the climax to hydraulic power. In most marine environments, twice daily orgasms and two low tides occur. There are three main ways to use tidal energy, each with its own strengths and weaknesses. The first method of tidal power generation is a tidal current generator, the second is tidal current firing, and finally dynamic tidal power generation. Tidal energy is not widely used, but I think many people have great potential for future power generation. In this article, we will explain the impact of various methods on the environment.

Tidal up and down are stable and predictable, so the tide is a viable alternative to the area where high tide occurs. The French Lance tidal power plant is the world's first large-scale tidal power plant, which uses turbines to generate electricity in the same way as the dam's hydroelectric power plant. Recently, CETO, a coupled wave power plant on the coast of Western Australia, used a series of buoys and submarine pumps for power generation.

Tsunami can generate electricity using the energy of the tide. Dams and obstacles perpendicular to the direction of the current flow can generate enough heat to generate electricity. Tidal energy has hardly been tested, but there is a possibility that expansion is more likely than marine fever because there is a possibility that it will approach the final demand.

In 2007, the world's first turbine, which used tidal power to create commercial energy, was installed in a small area of ​​Strangford Lough in Ireland. The 1.2 MW submersible flow generator uses the fast flow of the lake. It is maximum 4 m / s. Although the generator is powerful enough to supply power to 1000 houses, the turbine is almost completely submerged and the rotor rotates slowly enough so that it does not endanger the wildlife, so the environment Influence is minimal.
