Which of these statements about tidal power energy is false?

1. Tides are caused by the combined effects of gravitational forces exerted by the moon the Sun and the rotation of the earth.
2. Tidal power tidal power is a form of hydropower that converts the energy from the natural rise and fall of the tides into electricity.
3. Tidal plants can only be installed along coastlines. Coastlines often experience two high tides and two low tides on a daily basis. The difference in water levels must be at least ten meters high to produce electricity.
4. A tidal barrage is a dam that utilizes the potential energy generated by the change in height between high and low tides. This energy turns a turbine or compresses air which in turn creates electricity.
5. Tidal electricity can be created from several technologies, the main ones being tidal barrages, tidal fences, and tidal turbines. Tidal barrages are the most efficient tidal energy sources.
