Tough conditions for resuming U.K. fracking further stoke heated debate
After 18 months in limbo, frackers are back in business in the United Kingdom. But new regulations laid out by the British government are so tight that some advocates question whether the lid is really off hydraulic fracturing. At the same time, fracking opponents fret that the decision to lift the suspension of experimental drilling will launch a "dash for gas" that, at the very least, will derail ambitious plans for renewable energy and, at worst, will cause environmental havoc.
