Why use tidal energy?

Why use tidal energy?

Advantages and disadvantagestidal power has the advantage of being a energy renewable, which, after the construction of the dam, does not emit greenhouse gasesNatural phenomenon allowing an increase in the temperature of the atmosphere of a planet thanks to the presence of certain gases… .

How does tidal energy work?

Factory tidal produced from the tide of electricity on an industrial scale. Its operating principle is based on the use of the difference in height created by the amplitude of the tides to fill its reservoir and produce electricity.

How to use tidal energy?

Today another technique for harnessing the energy of the tides seems more promising: tidal turbines. These are turbines placed on the seabed, whose blades transform tidal currents into electricity in the same way as a wind turbine transforms the energy of the wind.

What are ocean tides?

This tidal force due to the Moon and the Sun between the Earth and a body of water in the ocean periodically modifies the surface of the globe which rotates on itself, which results in ocean tides. But it is the same for a fragment of the earth’s crust although solid; this phenomenon constitutes the terrestrial tides.

Why do tidal forces increase?

Tidal forces increase when the distance between bodies decreases. If two bodies get too close, there comes a point where these forces overcome the gravitational cohesion of the smaller body and it eventually breaks apart. This minimum distance is called the Roche limit, named after the French astronomer Édouard Roche.

What is the role of tidal currents on the climate?

Tidal currents also play a global role in the climate by contributing to the vertical mixing of the ocean, which cools the surface through contact with deep water. Finally, on the scale of geological time, the tide slows down the Earth’s rotation and moves the Moon away from the Earth.
