Wind Energy in the uk
Many people in the U.K are investing in wind energy technologies in addition or as an alternative to solar power. This is a positive step as wind energy is a key part of the UK's future energy growth and the governments plan to reduce carbon emissions. 40% of all the wind energy in Europe blows over the UK, making it an ideal country for small domestic turbines.
Where you live can be a big decider on whether you can implement an efficient renewable energy system such as wind power.
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 6kW
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.
BIG TIP: 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.
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.
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.
Is wind electricity suitable for my home?
There are a few factors to consider if a small scale domestic wind turbine is right for you:
- You need to consider whether there are large obstructions like buildings, trees or hills near your home as small domestic wind turbines work best in exposed locations, without turbulence caused by these types of obstructions.
- You will also need to consider if your home is in an area with enough wind. For the wind turbines to be effective you need an average windspeed of no less than 5m/s.
- If your home is in a remote location away from the National Grid, small wind turbines may be well suited.
- If you need planning permission. Small wind turbine systems generally will need planning permission.
Cut Energy Bills with Wind Turbines
Renewable Energy technology including Wind turbines can save money on your energy bills. Although the initial investment of these technologies can be quite high, in the long term they can be capable of paying for themselves.
You can buy a cheap, low efficiency wind turbine for as little as £200 to £400, depending on how much power you wish to generate.
