What are disadvantages of tidal energy?

Some of the disadvantages of tidal energy are: High tidal power plant construction costs. Negative influence on marine life forms. Location limits.

What is difference between Weir and barrage?

A weir is an impermeable barrier that is built across a river to raise the water level on the upstream side. … It is usually built on the other side of a flooded river.
