Wind Turbines

How do wind turbines work?

Wind turbines use large blades to catch the wind. When the wind blows the blades are forced round, driving a turbine which generates electricity. The stronger the wind, the more electricity produced.

There are two types of domestic-sized wind turbine:

  • Mast mounted: these are free standing and are erected in a suitably exposed position, often around 2.5kW to 6kW
  • Roof mounted: these are smaller than mast mounted systems and can be installed on the roof of a home where there is a suitable wind resource. Often these are around 1kW to 2kW in size.

If your small wind system is connected to the National Grid then you can make money by selling any generated electricity to an electricity supply company.

From 1st April 2010 you could be eligible to receive cash for each unit of electricity you generate using this technology.

If the turbine is not connected to the electricity grid then unused electricity can be stored in a battery for use when there is no wind.

The benefits of wind electricity:

  • Harness a plentiful energy source: in the UK we have 40% of Europe’s total wind energy.
  • Cut your carbon footprint: wind electricity is green, renewable energy and doesn’t release any harmful carbon dioxide or other pollutants.
  • Cut your electricity bills: wind is free, so once you’ve paid for the initial installation your electricity costs will be reduced.
  • Store electricity for a calm day: if your home isn’t connected to the National Grid you can store excess electricity in batteries and use it when there is no wind.
  • Sell electricity back to the grid: if your system is producing more electricity than you need, or when you can’t use it, someone else can use it – and you could make a bit of money.
