some information from a friend of mine who works at a power station, mostly it's what the guy said at the meeting but condensed and easier :p i basically asked him if he could give me any info on them this was his email response.
I can give you many, many reasons why it’s pointless and a waste of money BUT before I can do that I need to explain the situation. The government, greens and newspapers wants to see green energy. The People, apparently, want green energy. So it has to be put into practise. Windmills aren’t profitable; they only produce 2 MW (or so) per turbine and only do that 30% of the time. As an investment they’re obviously shit. So the government to keep the newspapers (and therefore the people) happy has said to power companies, we will give you subsidies for these projects to make them profitable. The companies (including British Energy) have gone, oh my god free money for putting up a windmill???. So that’s the background. We have the problem that the UK is small and the windmills need to go somewhere, hence they are going to go up in your neighbour’s back garden.
As for some reasons not to build them: they only run 30% of the time (known as unit capability factor), they don’t make anywhere near the amount of energy needed and lastly windmills cannot produce more than 10% of the country’s electricity as the wind isn’t constant enough (the grid doesn’t like bouncing loads). To put it in perspective, Dungeness B Power Station makes 1100 MW or 550 windmills worth and it does it 90% of the time.
As for weirdness, depleted uranium is used to fill the ends of the rotors, they chop up birds AND they aren’t qualified for anywhere near the level of a nuclear power station. If we had one of those rotor’s spinning at nearly the speed of sound shoot off like one did in Holland and landed on someone’s house, well you do the maths.
