It isn't just the windmills, for sure, but alternative energy solutions need to be checked and balanced on an effective base load from conventional energy.
We will thus be landed in the ludicrous position of having to spend an additional £10 billion on those 17 dedicated power stations, which will be kept running on "spinning reserve", 24 hours a day, just to make up for the fundamental problem of wind turbines. This is that their power continually fluctuates anywhere between full capacity to zero (where it often stood last winter, when national electricity demand was at a peak). So unless back-up power is instantly available to match any shortfall, the lights will go out.
Two things make this even more absurd. One, as the energy companies pointed out to DECC, is that it will be amazingly costly and wildly uneconomical, since the dedicated power plants will often have to run at a low rate of efficiency, burning gas but not producing electricity. This will add billions more to our fuel bills for no practical purpose. The other absurdity, as recent detailed studies have confirmed, is that gas-fired power stations running on "spinning reserve" chuck out much more CO2 than when they are running at full efficiency – thus negating any savings in CO2 emissions supposedly achieved by the windmills themselves.
Is there no longer anyone around at DECC who is familiar with these very basic practical points? The policy on which our national energy strategy is now centred is a ludicrously expensive, self-defeating joke, which will achieve no benefits whatever – even if you are among the diminishing number of people who still believe that man-made CO2 is causing catastrophic climate change.
