The diagrams below show a structure that is used to generate electricity from wave power. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagrams illustrate a mechanism which produces electricity from seawater .

Overall

,a structure is located in the sea and uses its water.The first picture shows that the

wind

which is caused by

waves

spins a turbine and produces light.

On the other hand

,the second picture illustrates that

waves

cause the

wind

which is in the opposite direction and by ,

this

the light produces too.

Firstly

,the machine is on a cliff or a sea wall.

This

place provides the best way for collecting wave power.In the first ,picture

waves

blow the

wind

inside the structure.At the top of it is the chamber which probably is used for controlling the high of the wave.

However

,The air that goes through the column makes the turbine spin.By ,

this

the turbine makes the energy which provides electricity.

Secondly

,the second photo shows that when

waves

ebb they cause the

wind

too.

Moreover

,It goes through the column again and spins it in the same direction,providing the light again.
