Would the noble Lord accept that the figure that came out last week for the amount of shale gas under the UK is far higher than was assumed when his report was written? I went to talk to Cuadrilla at one point last year. I said that the 200 trillion cubic feet that they were talking about under Lancashire was being ridiculed as a very high number and asked whether they stood by it. They said, “Privately, we think it is much higher. It is about 300 trillion cubic feet but we dare not say so because people will not take that seriously”. Then an independent consultant, Nick Grealy, said 700 trillion cubic feet and everybody laughed at it. Now, the British Geological Survey has said there is 1,300 trillion cubic feet. This is the largest find of shale gas ever on the planet. The shale rock we are talking about, the Bowland shale, is in places 10 times as thick as the Marcellus shale in Pennsylvania.
I went to see shale gas extraction in the Marcellus shale in 2011 because I had heard about it and thought it was interesting. You could hardly find these well pads—they are tiny and hidden among the trees. There was a flock of wild turkeys running across the road on the way to one. I asked somebody for a calculation of just how much energy can come out of a small area when you are drilling for shale gas. The answer is that about 25 acres of well pad in Pennsylvania can produce as much energy from shale gas as the entire UK wind industry produces at the moment.
