Many argue that fracking to harvest shale gas creates environmental nightmares. We may not even need it as renewable energy has become competitive with fossil fuels. The UK is late entering the fracking game. Very late, according to a British geologist who argues that the island of Britain was lifted and tilted 55 million years ago and, as a result, the rocks holding the shale gas are not buried deep enough and are, therefore, too cold to be fracked. That’s good news for the environment.
