Domestic Turbines
Generate electricity at home with small-scale wind turbines
40% of all the wind energy in Europe blows over the UK, making it an ideal country for small domestic turbines. Wind turbines harness the power of the wind and use it to generate electricity. Small systems known as "microwind" or "small-wind" turbines can produce electricity to help power the lights and electrical appliances in a typical home.
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 50kW
- 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 renewable technologies are eligible to receive cash for each unit of electricity you generate using renewable technologies.
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.
In the UK we have 40% of Europe's total wind energy.
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.
Is Wind Electricity Suitable for my Home?
To tell if a small scale domestic wind turbine is right for you, there are a few key questions to consider:
- Are there any large obstacles like buildings, trees or hills near your home? Small domestic wind turbines work best in exposed locations, without turbulence caused by these type of obstacles
- Is your home is a windy area? To be effective you need an average windspeed of no less than 5m/s.
- Is your home located away from the National Grid? Small domestic wind systems are particularly suitable for use in remote locations where mains electricity is unavailable.
- Do you need planning permission? Small domestic wind systems normally do require permission from your local authority, so check before you install a system.

Costs & Savings
Costs for a roof mounted microwind system are about £2,000-£4000 Larger mast mounted systems cost start from £10,000 upwards , including VAT at 5% and installation.
Savings: Recent monitoring of a range of small domestic wind systems has shown that a well sited 6kW turbine could generate around 10,000kWh per year which is equivalent to around 5.5 tonnes of carbon dioxide a year. A system this size could generate income and savings of around £3,500 a year from the Feed In Tariff.
Maintenance checks are necessary every few years, and a well-maintained turbine should last over 20 years. For off-grid systems, battery life is typically between 6 and 10 years.
