Energy production is one of the few bright spots in the American economy. A back of the envelope cost-benefit calculation from a Yale-associated group estimates that recent increases in shale gas production have been worth just over $100 billion annually to US consumers. In comparison, the authors estimates that groundwater contamination costs $250 million per year, a 400 to 1 benefit to cost ratio. The calculation is crude and the authors do not take into account environmental benefits from using natural gas over coal but the ratios are of interest.
