Wind Power
Contents
Key Stage 3
Meaning
Wind Power is an energy resource that uses the flow of the wind to generate electricity.
About Wind Power
- Wind Power is a renewable energy resource.
- Wind has energy in the kinetic energy store of the moving air.
Power
Wind Power can be used to generate electricity.

- 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.
Advantages
- Can provide power in places not connected to the national grid.
- Do not produce pollution.
- The running cost is almost nothing.
- No fuel cost.
Disadvantages
- 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.
