Question

Define tidal energy and write one limitation of using tidal energy .

Answer 1

Dear student ,

Tidal energy is the kind of energy that exists because of the gravitational interactions between the moon and the water mass of the earth and also the sun and the water mass of the earth. A big advantage of tidal energy is its predictability. The size and time of tides can be predicted very efficiently. Tidal energy is a renewable source of energy.

The tidal energy is not likely to be a potential source of energy in future due to the following limitations:

1-Less availability of suitable sites for building tidal barrages around the world.

2-The rise and fall of sea water during high and low tides is not enough to generate electricity on a large scale.

3--Start up costs to build a tidal energy plant is high.
