The Times seems to have got sight of the British Geological Survey's new estimates of Britain's shale gas resource. The previous figure of 1000 tcf, widely pooh-poohed by greens, has been upped to between 1300 and 1500 tcf. Current demand is about 3tcf per annum.
It's only fair to note that not all of this will be extractable and the Times suggests a figure of 20% might apply with current fracking technology. That would be around one hundred years' supply.
I recall Roger Harrabin's tweet back in October:
