The technology is still in its initial stages and not fully formed. It is supposedly going to be a costly affair to finally be able to device a method to produce energy from tides.

There could be environmental and marine disruptions due to the construction of equipments to produce energy from tides.

There is a geographical restriction in producing tidal energy as seas or oceans with ample amount of tides are not situated in every part of the world.
