Energy from wind and water

?
How is electricity generated from wind?
Wind turbines. Wind passing over the blades rotates them and drives a generator at the top of a narrow tower.

What ways can electricity be generated using water?
Electricity can be produced from energy obtained from falling water, waves or tides.

How does hydroelectric power work?
In hydroelectric power stations, water is collected in a resevoir. This water is then allowed to flow downhill and turn turbines at the bottom of the hill.

How does wave power work?
We can use the movement of the waves on the sea to generate electricity.

How does tidal power work?
The level of the sea around the coastline rises and falls twice a day. These changes are tides. A barrage built across a river estuary traps the water. When it is released to fall down to the lower sea level, it turns turbines.
