- A wind turbine generates electricity from the power of the wind.
- When the wind blows, the turbine blades turn a generator inside the turbine that converts the movement into electricity. That power is then transmitted through underground cables.
- So a wind turbine is rather like a giant fan in reverse!
- Wind turbines generate electricity from wind speeds of 4 to 5 metres per second (10 miles an hour) upwards. They only stop working when wind speeds reach severe gale force, at about 25 metres per second (50+ miles/hour).
- Currently the fastest growing source of renewable energy in the world.
- Scotland is the Windiest place in Europe.
- There are over 1000 wind turbines in the UK.
- A 1.8MW turbine supplies enough electricity to power 1,000 homes.
- One wind turbine produces enough electricity each year to run a computer for 1620 years!
- A wind turbine will last for about 20-25 years with some part replacement required in its life time.
- It is predicted that onshore wind farms will provide about 5% of Britain’s electricity by 2010.
- The largest turbine in the world is 20 stories high and has blades the length of a football field.
- Wind energy is freely available.
- Potential for large scale electricity generation.
- Low running costs.
- No waste or pollution from power generation.
- Taking down a wind farm is straightforward.
- Wind farms can become tourist attractions.
- The land can still be used for farming.
- Difficulties with connecting to the national grid
- No wind, no power
- A speed of at least 4m per second is required
- Can interfere with radar
