Could You Generate Electricity From Wind?
July 17 2009
The Energy Saving Trust has recently completed trials to give UK home owners an indication of whether they would be able to generate electricity from the wind at their home.
To find out whether your home may be suitable for a domestic wind turbine, how much it costs and how it works, there is some useful information on this link on the EST website.
If your home isn't suitable for a wind turbine, the EST also have information on other technologies that might be suitable to generate heat or electricity for your home. These include wood burners and ground source heat pumps.
My main supply is gas and so, for me, there would be very little savings to convert to any of the eco-friendly options, and at £7000 to £20,000 outlay with a twenty year payback before I break even (at current costs) it will not be a tempting offer to many householders.
However, a roof-mounted wind turbine seems, on the face of it, to be quite a good option if you are high up or exposed to plenty of wind (we are the windiest country in Europe after all!). Costs for a roof mounted microwind system start at about £1,500, providing enough electricity for lighting and appliances in a typical home.
According to the EST, 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. This is great because there are no other costs after buying and installation (other than batteries, which have a life of approximately 6 to 10 years)
