Power Stations

Wind Power.

Wind power uses wind turbines which have their own generator built in.
A wind turbine looks like a windmill with three blades.
When the wind blows, the windmill rotates
and the turbine generates electricity.

The original source of the energy is the Sun which makes the wind blow.


Advantages of wind power.

1.  It is renewable.

2.  It does not cause pollution (except noise).


Disadvantages.

1.  It is unreliable.
When the wind drops,
the turbine turns more slowly and less electricity is generated.

2.  An individual wind turbine
does not generate very much electricity.
You would need a lot of them to replace one fossil fuel power station.

3.  The natural beauty of an area may be spoiled.
