Question

advantages and disadvantages of tidal energy

Answer 1

The advantage of tidal energy is that it is a renewable source of energy. It is present in unlimited amount in nature.
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.
