Question

Explain how tidal energy generates electricity?(5 marks)

Answer 1

Tidal Power. Tidal energy is produced through the use oftidal energy generators. These large underwater turbines are placed in areas with high tidalmovements, and are designed to capture the kinetic motion of the ebbing and surging of oceantides in order to produce electricity.

Answer 2

The movement of the sea water isharnessed in a similar way using waterwheels and turbines to thatused to generate hydro electricity. But because the sea water can flow in both directions in a tidal energy system, it can generate power when the water is flowing in and also when it is ebbing out.

Tidal stream generators are very similar to wind turbines except their below the water surface instead of above or on land. The turbine and generator converts the movement of water coming from change in tide, the kinetic energy, into electricity
