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

How do I find out if my site is windy enough for a wind turbine?
Our survey takes into account the average wind speed in your area, so should give you a broad indication of whether your location is suitable for a wind turbine. We do recommend that you measure the average wind speeds in the turbine locations you're considering for at least a year before committing to an installation. You can measure your wind speed using an anemometer (wind meter). A good anemometer will record your specific wind profile (e.g. average wind speeds, wind spikes, changes in wind direction) which will help you select the most appropriate wind turbine for the wind characteristics of your site. The Power Predictor anemometer from www.bettergeneration.co.uk is a good choice for a domestic installation.
How does a wind turbine generate electricity?
Most wind turbines have three blades which face into the wind; the wind turns these blades round. This spins the shaft, which is connected to a generator. The generator turns this mechanical energy into electrical energy, generating electricity. This electricity is passed through an inverter to convert it from CD to AC electricity, and this AC electricity is then supplied to your house through your wiring.
Can I connect my wind turbine to the grid?
Most areas of the UK are connected to the Grid, and if you are, you can connect your turbine to it too. This will allow you to qualify for the Export Tariff as part of the Feed-in-Tariff scheme, which pays you acsecond payment on top of the Generation Tariff for any electricity that you generate but don't use. The surplus electricity is automatically exported to Grid.
What happens to my electricity supply when the wind stops blowing?
Without adequate wind blowing, the turbine will not turn and create electricity, therefore you will have to draw power from the grid. This will happen automatically as long as you are connected to the Grid.
