The building of tidal energy turbines is an expensive process, though after the initial payments, the cost of generating electricity is low.

Tidal energy is a form of hydro power that is derived from the movement of water (tides), driven by the gravitational pull of the Moon.

As the turbine spins due to the push and pull of the tide, electricity is generated.

Tidal energy is a renewable source of energy which costs very little to maintain after the initial investment.

It does not emit any greenhouse gases, and is also land-efficient.

Tidal energy is a stable source of power, as the tides are guaranteed and predictable.

However, the initial investment for the building of tidal plants and turbines is extremely expensive.

Furthermore, tidal energy does not have the potential to become a major energy source, as the difference in water level between high and low tides is not great enough to generate sufficient energy.

Finally, the infrastructure of tidal energy can have a negative effect on the area in which it resides, as well as possibly driving away tourists and therefore economic opportunity.
