Meanwhile here in the North East of England the coastline is disappearing under a wall of wind turbines and another contract has just been signed. We can see for ourselves that in the very cold still air between weather fronts they are not working and then in the high winds again have to be shut down, they are OK in summer when we have mild winds and it is warm in other words not needed.

What you describe is the huge major problem with wind turbines, but one which the alternative energy zealots refuse to acknowledge. The time we need electricity most is in extended cold spells in winter. These are caused in the main by large areas of high pressure sitting over the country, and large high pressure areas mean low, to no, wind and therefore little to no electricity production from wind turbines.
There are really probably only two truly reliable and sustainable forms of 'alternative energy', hydro and wave/tide. Those are the areas on which money should be spent to get the best bang per buck in the long term.
