Don't try to persuade the people of Great Britain to back fracking by paying them off with badminton courts, writes Michael Hanlon in the (U.K.) Guardian.
Hanlon: "This is not a spoof: it is actually being considered by the coalition, on the advice of the energy and climate change select committee, as a way of getting the people of Lancashire and elsewhere to drop their opposition to fracking, a controversial technology that extracts natural gas by blasting it out of ancient, deeply buried shale strata. A country that led the way with civil coal and nuclear power, and whose efficient national grid was a symbol of the postwar drive to modernise, is now basing energy policy on bribing villagers with badminton courts.
"This is not an argument against fracking per se. The theoretical potential is there, under the carboniferous rocks of the English north-west and the Scottish central belt, for an energy revolution on the scale of North Sea oil. A recent British Geological Survey report put the amount of shale gas under the UK as 250 times that of previous estimates, enough to make us self-sufficient in gas for centuries. That deserves a big tick."
