tidal wave energy


Let us learn about tidal wave energy.

Tidal wave energy is based on the movement of the tides & power of the ocean, the tidal energy was used as a source of power to grind meal from grain. The fact that ocean wave energy is 100% eco-friendly without any greenhouse gas emissions and relatively low carbon footprint on the Earth, the future is bright for this natural energy source.

Wave turbines, similar are function and look to wind turbines, are placed under the water. As the water moves, do the turbines & thus electricity & the generators is produced. Power harvested from tides in a fashion similar to hydroelectric energy recovery.

As the tide rises to high, water is trapped behind a wall. When the tide recedes, this water is let out finished raft gates where turbines twist (water is let out through flood gates where turbines (reel) spin) and force & power is created. This process is a very slow process because it takes 12 hours for the tide to move from low to high. Then another 6 hours for the tide to retreat back to low again. The main demerit of tidal wave energy is the cost of plant production and the time needed to establish a fully working plant.


In our next blog we shall learn to solve problems by using grade 7 math worksheets I hope the above explanation was useful.Keep reading and leave your comments.
