Your article in News stand (NCE 3 March) was a remarkable case of biased reporting.
When a German government report states that it is more effective to reduce CO2 emissions by improving energy efficiency in houses than to build wind farms it is a gross distortion to conclude that 'wind farms are expensive and inefficient'.
It would make more sense to promote the view that priority should be given to insulating buildings and improving heating efficiency.
That does not seem to hold much favour with governments and the engineering profession, presumably because of the need to deal with real people rather than the more profitable supply side of energy.
