What Mr Cameron clearly hasn’t realised is that the main reason why our energy companies need to charge us ever more for electricity lies in his own Government’s deluded policies. He and his colleagues prattle on about how, over the next eight years, we need to spend £100 billion on building 30,000 useless, unreliable and grotesquely subsidised wind turbines. They want to see billions more spent on giant pylons and interconnectors, to carry power from the remote onshore and offshore wind farms where it is generated to the places where it is needed. Then, as even Mr Davey has finally admitted, further billions will need to be spent on new gas-fired power stations – not only to fill the gap left by all the coal-fired and nuclear plants that are due to close, but also to provide ever more expensive, “carbon”-emitting back-up for the times when the wind drops and our turbines are scarcely functioning.
