Firstly, apologies if this kind of thing has been posted before.
I live in Devizes in the UK, and I'm interested in installing a small
domestic wind turbine to my house (therefore it would have to be really
quite small to avoid planning problems, etc). My questions are:
How much would a suitable wind turbine cost me?
Who makes them?
How do I connect to the electricity the turbine creates?
How much electricity can it generate? What is this in layman's terms?
Can I install the turbine myself?
Is there enough wind, and how can I measure this beforehand?!
Can anyone help with this? I'm really keen to do my bit for the
environment and wind power seems to be the cleanest and most
sustainable power option, but it's really quite difficult to get simple
answers to my questions!

Advice- DON'T attach it to your house. Our house has passive roof
turbines to exhaust hot attic air. They are very lightweight and free
spinning. After the last hurricane, I found them in a neighbor's
yard, bent them back into shape, and re-installed them. They look
perfect, but the slight variation from perfect balance makes them
thump just a little when they rotate at speed. That thump gets
transmitted down through the rooof deck, rafters, ceiling joists, and
ceiling, and is plainly audible inside, to the point that I am going
to have to replace them. If those few ounces of rotating spheres of
metal are a problem, imagine the noise and vibration that a wind
turbine would create when attached to a dwelling.

Much of the information I've found applies to the USA but this site can give
you an idea of what to search for:
Unless you have very consistant wind it would probably not be a practical
In most places in the USA it is possible to connect wind/solar power
directly to the "grid" via a grid-tie inverter. This method basically
supplements your electricity and reduces your monthly bill. In most cases
it is cheaper just to buy it from the utility company because it takes a
long, long time for solar/wind to pay for itself, if ever.
Another option is a stand-alone system that charges batteries and in most
cases an inverter attached to the batteries supplies you with AC power.
Places like this sell the equipment: http://www.solar-electric.com/ in the
With a little searching on Yahoo you should be able to find companies that
supply equipment that operate at the proper voltage and frequency for your

Not sure on the cost, you will have to ask the companies for a quote. I
am aware that there is a UK governemtn scheme called 'clear skies'
which gives you a grant for domestic wind turbines to cover some of the
cost. You can also sell spare electricity back to the grid if you opt
for a grid connect turbine
are two uk companies that i know of. Proven are particularly good if
you have abit of land to put up a mast.
Either grid connect - where the turbine is wired into your distribution
box. Or via batteries... where it is isolated from the mains. A grid
connect turbine is not allowed to generate in event of a power cut.
5KW = 83 light bulbs
The biggest domestic turbine available is about 15KW
Depends if you know what you are doing! You would have to get any
domestic connection/wiring checked by someone who is part P registered.
should help. Most companies recommend an average wind speed greater
