Peter Hoskin. Wind power: so much hot air? Spectator. 2/2/2008.

A study of the UK’s 165 wind farms shows they are not significantly cleaner, nor cheaper than conventional energy generation. Wind is unreliable; sometimes wind farms produce a surfeit of electricity, other times next-to-nothing. This means they require a contingency plan - usually, coal-fired power stations kept running in the background, ready to step in as necessary. However, the CO2 emissions generated by the “stand-by” power-stations aren't counted in the “carbon reduction” totals for wind farms.
