Tidal Energy
Physics: AQA GCSE Higher, topic 1.3.6
Tidal Energy
The waves and tides in the sea are stores of kinetic energy. Tidal and wave power use this kinetic energy to rotate a turbine, which turns a generator.
Advantages
- Renewable source of energy.
- Does not produce greenhouse gases.
- Tides are a predictable phenomenon.
Disadvantages
- The creation of tidal turbines can damage fragile ecosystems in estuaries.
- Does not produce electricity continuously.
- Turbines must be built close to the shore, affecting communities that live there.
