Key Stage 3
Meaning
Tidal is an energy resource which uses tides to generate electricity.
About Tidal
- Tidal is a renewable energy resource.
 - Tidal has energy in the gravitational potential energy store of water that is being pulled by the moons gravitational pull.
 - Tides happen twice a day. Once when the The Moon is directly overhead and once when the The Moon is on the opposite side of the Earth.
 
Power
- 1. As the tide changes water passes through the pipes in the tidal barrage.
 - 2. The water causes turbines to turn.
 - 3. The turbines spin a generator which makes electricity.
 
Advantages
- Do not produce pollution.
 - Very reliable (high tide occurs twice a day).
 - No fuel costs.
 - Power output can be varied by opening and closing sluice gates to control the water flow.
 
Disadvantages
- Cost to build is quite high.
 - Prevent access to boats.
 - Tidal height varies throughout the year.
 - Damages habitats by not allowing the natural flow of the tides.
