Energy and climate change secretary Ed Davey says energy reforms have not been made unnecessary by the unearthing of European shale gas deposits. He also rejected suggestions that the emergence of new shale gas supplies make a 'dash for gas' attractive. "Yes, prices can go down, as well as up," he said. "And yes, unconventional gas can make a difference, although perhaps not as big a difference as some sections of the press would have me believe."
