Wind Power is an energy resource that uses the flow of the wind to generate electricity.

Wind Power is a renewable energy resource.

Wind has energy in the kinetic energy store of the moving air.

Wind Power can be used to generate electricity.


A diagram of a Wind Turbine.

1. Wind moves past the rotary blades of the turbine.

2. The turbine spins.

3. The turbine causes the generator to turn.

4. The generator makes an electrical current.

Expensive to build.
Need over a thousand to generate the power that a single coal power station would make.
Only work when it’s windy (70-80% of the time)
If it is too windy they have to be stopped for safety.
They produce a lot of noise, annoying local people.
Cannot increase power output when more is needed.
