The benefits of wind power
In the right situation micro-wind turbines are a very effective energy solution and could contribute up to £3,200 per year to your energy costs.
- Harness a plentiful energy source: In the UK we have 40% of Europe's total wind energy.
- Cut your carbon footprint: Wind electricity is a low carbon, renewable energy source and doesn't produce any pollutants. A well sited 6kW system can save around 5.5 tonnes of carbon dioxide a year.
- Cut your electricity bills: The wind is free, which means that after the system has paid for itself your electricity costs will be reduced.
- Store electricity for a calm day: If you don't connect your turbine to the National Grid you can store surplus electricity in batteries and use it when there is no wind.
- Quick payback: A large system typically pays for itself in 7 years or less under current tariff rates.
- Receive FIT payments: You can be paid for any electricity you generate using your turbine and any electricity you don’t use which can be exported back to the Grid. This adds up to around £2,800 a year.

Savings with a typical system
Studies looking at a number of different of microwind systems indicate that a well situated 6kW turbine could generate:
- Around 10,000 kWh of electricity per year
- Savings of around 5.5 tonnes of carbon dioxide a year.
- Around £3,200 a year in Feed-in-Tariff payments and bill savings for 20 years.
What to do next?
- Will a wind turbine work if I live in a built up area?
- The industry tends not to recommend that a domestic wind turbine is installed in an urban environment for a number of reasons, including: increased turbulence, resulting in higher stresses on the turbine and lower energy capture for any given wind speed; increased margins of safety required when more people are living and working near the turbine; additional measures possibly required to limit the transmission of vibrations into the structure of the building and lower average wind speeds in a city environment reduce the annual energy capture.
- Should I get a wind turbine if there are frequently low wind speeds in my area?
- Micro wind turbines can be selected for good low wind speed performance, so that even on less breezy days, electricity can be generated.
- Will my wind turbine impact wildlife?
- Livestock are able to graze in the same field as a freestanding turbine, undisturbed by its presence. Similarly, there is no evidence to suggest damage to other wildlife despite research having been carried out.
- 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.
