Generate electricity at home with small-scale wind 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.See how wind turbines work with your home
40% of all the wind energy in Europe blows over the UK, making it an ideal country for small domestic turbines.
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:
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.
In the UK we have 40% of Europe's total wind energy
To tell if a small scale domestic wind turbine is right for you, there are a few key questions to consider:
Use our new wind speed prediction tool to help determine if your site has a good enough wind speed for a domestic scale wind turbine

To make the electricity you produce go further:
Costs for a roof mounted microwind system start at about £1,500. Larger mast mounted systems cost between £11,000 and £19,000, including installation. These provide enough electricity for lighting and appliances in a typical home.
Savings: Recent monitoring of a range of small domestic wind systems has shown that a well sited 2.5kW turbine could save around £380 a year off electricity bills when some generation is exported, and a saving of around 2.6tonnes of carbon dioxide per year.
Maintenance checks are necessary every few years, and a well-maintained turbine should last over 20 years. Battery storage life is typically between 6 and 10 years.
