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.
Despite the fact that geothermal energy is renewable and practically inexhaustible source of energy, world is still using very little of total geothermal energy potential, mostly because with currently available technologies only areas near the tectonic boundaries can be profitably exploited.
