California may turn to fracking its vast shale reserves to rescue the troubled state, says Joel Kotkin at the website Newgeography.
Kotkin: "The recent announcement that Jerry Brown is studying "fracking" in California, suggests that our governor may be waking up to the long-term reality facing our state. It demonstrates that, despite the almost embarrassing praise from East Coast media about his energy and green policies, Brown likely knows full well that the state's current course, to use the most overused term, is simply not politically and economically sustainable.
"Although largely a prisoner of basic green dogma, Brown also is a former Jesuit, with that order's sense of rationality, order and, well, philosophical flexibility. Unlike many of his progressive idolaters and legislative allies, Brown may well be intelligent enough to look past the rhetoric of the environmental movement and consider its often unexpected ill-effects."
