Disadvantages of Tidal Energy. There are a limited number of locations worldwide that have tidal ranges large enough to make tidal power cost-effective. Tidal power systems are currently expensive to develop and they cannot be built in any location. Tidal energy systems that use dams may restrict fish migration.
There are also three main ways that tidal energy is harnessed: 1  Tidal Barrages-A tidal barrage works like a dam. 2  When the tide goes high, the reservoir fills up. 3  When the tide drops the dam lets the water out. 4  In both directions the moving water can spin the blades of turbines to create electricity.
