Why is tidal energy not likely to be a potential source of energy?
The tidal energy is not likely to be a potential source of energy because:
(i) The rise and fall of sea-water during high and low tide is not so high to generate electricity on a large-scale.
(ii) There are very few sites in the sea around the world that are suitable to build dams.
(iii) Start up cost to build a tidal energy plant is high.
