Alistair Buchanan, chief executive of Ofgem, said the combination of UK power plants closing, foreign gas supplies shrinking, and demand rising, has made British energy reserves “uncomfortably tight”.

Writing in The Daily Telegraph ahead of an industry lecture today, Mr Buchanan has warned: “We have to face the likelihood that avoiding power shortages will also carry a price.”

Given that we have discussed this issue before, I wonder if we might turn our attentions to what is going to happen when the lights go out.

Who will get the blame? Renewables obsessed greens and their crony capitalist friends? Or wicked sceptics standing in their way? Will the main political parties be swept aside? Or will they merely change their tune and say they opposed it all along?

We are heading for interesting times, where "interesting" is as defined here.
