As long as governments pump billions into the wind industry in the mistaken belief that it generates longterm employment no amount of pointing out the obvious will help.

I decided to show something useful instead of waiting until perfect data is available.
Frequency plot of wind speed over the whole of the UK. The characteristic is logarithmic.

The Met Office in common with all national meteorological services continue to use cup anemometers rather than eg. ultrasonic This is the advice from WMO (World Meteorological Organisation) specifically to maintain continuity of data for climatic purposes since there are significant differences between cup and other types.
