Wind Power

You can generate electricity at home with small-scale wind turbines.

Domestic wind turbines, known as microwind or small-wind turbines, capture the power of the wind and use it to produce electricity to power the lights and electrical appliances in your home. The UK is the ideal country for small domestic turbines with 40% of all the wind energy in Europe blowing over it.

The Basics

Whenever the wind blows over your domestic wind turbine it will use this energy to generate electricity. This electricity can be used to power your home’s appliances and lighting, and because this electricity is free to you this will reduce your electricity bills. If you qualify for the government’s Feed-in-Tariff scheme you can receive payments for every unit of electricity you generate, as well as for any units you generate but don’t use, as they can then be exported back to the Grid.

You can fit a roof mounted or mast mounted (freestanding) microwind turbine depending on what the best way to capture wind power is in your area. Find out more about Installation of Wind Turbines here.

A well sited 6kW turbine could generate around 10,000kWh per year which is equivalent to around 5.2 tonnes of carbon dioxide a year. A system this size could generate income and savings of around £3,200 a year when eligible for the Feed-In Tariff” (Energy Saving Trust)

FAQs

Will a wind turbine have an impact on local TV and radio reception?
The materials used to make the turbines are unlikely to 'chop up' a signal and create electromagnetic interference (EMI).
How much do wind turbines cost?
A typical 1kW roof-mounted wind turbine will cost around £2,000, with larger 2.5kW and 6kW freestanding (pole-mounted) systems costing around £15,000 and £22,500 respectively.
What maintenance or servicing is required for a wind turbine?
You should get your turbine checked by your installer or another accredited technician every year, which should cost between £100 and £200. Your inverter may need to be replaced once during the turbine's 20 year lifetime - this costs between £1000-£2000 for a large freestanding system. Turbines with batteries (off-grid systems) will need their batteries replaced every 6-10 years.
What size wind turbine will I need?
The size of the turbine that's right for your property will depend on a few factors, including whether you want to have a roof mounted or freestanding system, your local wind speeds and the planning restrictions in your area, You should check with the Government's Planning Portal and with your installer when planning your turbine installation.
How tall are domestic wind turbines?
The height of a domestic turbine will vary according to manufacturer and model, but generally it varies from 6 to 15 meters (for a roof mounted system) up to 24 meters for a freestanding turbine. In general, the higher up the blades are, the higher the average wind speed that the turbine will experience, giving you a more efficient system. The rotor diameter of domestic wind turbines ranges from 2 meters for a roof mounted turbine, up to around 7 meters for a freestanding turbine, again depending on the model.
