Britain saved by coal – at huge cost

windmill20scamThe old question of where the electricity supply is supposed to come from when the wind doesn’t blow keeps coming up, and no satisfactory answer – if there’s any answer at all – is ever heard. Today could be a repeat as wind is currently (9:15 am) supplying a lowly 6% of demand, with similar weather conditions. Of course none of this should be a surprise, as climate dogma can’t overthrow reality. Soon enough coal burning will be history in the UK.

Britain’s fragile electricity system is a national embarrassment and a warning to the world, says The GWPF.

The entire UK wind fleet was in effect completely absent for much of the day, only rising above a few percent of its theoretical output late in the day when the crisis was over.

As a result, conventional gas- and coal-fired generators had to be fired up. The UK’s creaking grid was therefore effectively being propped up by fossil fuels.

The cost of these actions was very high, with some units being paid as much as £4,000 per megawatt hour to switch on, an exceptional price by any standard.

The balancing cost of avoiding blackouts has been increasing rapidly and is expected to hit 1-2 billion pounds this year, burdening consumers with ever more expensive electricity bills.

  1. On a large commercial scale wind definitely does seem to have its drawbacks. However, we have had much success with Point-Of-Use power generation and even some new technologies that in combination with the lithium iron phosphate batteries, do look to show some promise on a larger scale.

    Switching back and forth as is so common these days is certainly unsustainable, as the coal plants tend to generate substantially more pollution on startup.

    Batteries don’t generate any power, only recycle it, and only work for short periods at small scale – and are expensive. May also catch fire.

    Why we can’t rely on wind power

    Judging by the cartoon, when the world runs out of birds, it will run out of bird supplied energy (bird chopping).

    Not really. Could be a bargain.

    The coal plant operator has to be compensated for his fixed cost, else he closes shop. He always includes it in his rate. It used to be spread over continuous usage, now, with sporadic usage, it gets dumped in all at once.

    The rate payer is going to pay it, one way or the other. Over time, or in big lumps. If you want backup, you have to pay for it. In big lump sums, in this case.

    “On a large commercial scale wind definitely does seem to have its drawbacks….”

    For the last 20 years the impossibility of running a Grid on intermittent power has been well explained by electrical engineers, who were then cancelled.

    Running a hybrid system with fossil fuel backup is twice as expensive as running a fossil fuel system alone, and generates MORE CO2 than an efficiently optimised system using fossil fuel alone.

    I presume it is pointless to explain that limiting CO2 output is a completely useless undertaking in any case, since it does not impact the global temperature in a catastrophic way – in fact, the impact of maximum human output is indistinguishable from natural variation. ‘Models’ insist that the Earth’s temperature must be rising rapidly, but observations show it to have not varied at all over the past 7 years.
