I think Wind turbines can have a part to play in the UK power need
The highest electricity demand in UK is on a cold winter's morning following a long clear night (clear sky, light or nil wind), how do wind farms help us then? They are a fashionable response which found favour in Labour's indecisive govt as they could be seen to be doing something instead of cutting to the chase and building nuclear power stations.
Generally only one turbine will be lit on a wind farm.
