Domestic Wind Turbines for your Home
One of the fastest growing renewable technologies worldwide, wind turbines extract kinetic energy from the wind which when it blows forces the blades of the turbine around, which drives a turbine to produce electricity. Turbines are either pole-mounted on the ground or mounted on roofs.
Micro-wind turbines suit domestic requirements, having being used for centuries to power remote communities. They come in a variety of sizes and powers, generating anything between 100W to 50kW. The diameter of the blades tend to be several meters. The speed and direction of wind in your area will determine the amount of electricity a small-scale turbine can produce, as well as the amount of obstructions nearby such as hills and trees that reduce wind speed.
A reliable estimate of the wind speed at the proposed site of the turbine will be required, often a professional measurement is preferable or an estimate of annual mean wind speed can be found using the UK Wind Speed Database. Speeds of 5m/s or more are recommended by most manufacturers.
Advantages of domestic wind turbines include:
Making use of a plentiful, free resource with the UK experiencing 40% of Europe’s wind
Earn money for every kilowatt of electricity you produce, through the Feed-in Tariff, whether you use it at home or export it to the national grid.
The Green Deal can help with the costs of installing a micro-wind turbine
Electricity can be stored for when the wind is not blowing in batteries
The life span of a turbine is usually about 20 years
Your CO2 footprint will be reduced as you are providing your home’s electricity needs through a clean, renewable energy source.
