Wind-Farm Carbon

A letter appeared in the Daily Telegraph from Simon Davidson of Cardiff: (12 Dec 06)

Sir - Your report (DT December 9th) says that wind farms fail to produce enough electricity, and that the turbine at the HQ of Renewable Energy Systems produces 7.7% of the maximum possible.

You reported the managing director as saying 'each unit is zero carbon and you can't get better than that'.

Can't you? He does not say how much carbon was produced in manufacturing the useless machine, transporting it and making the huge concrete base it has to sit on.

If you take all this into account, each unit of electricity will create more carbon dioxide than the worst coal-fired power station.

ND comment - I have seen papers written by energy professionals saying that wind power costs around 4p a unit. However I have not found any measured data, on the internet or elsewhere, to support this claim. If you aware of such data, I would like to hear from you. It would be interesting to check the figures.
