A report issued by the National Association of Regulatory Utility Commissioners (NARUC) concludes that continuing oil and natural gas exploration and production moratoria off the U.S. East Coast would likely have significant negative effects on the U.S. economy. The model used in the study predicts, among other things, that by 2030, U.S. crude oil production will decrease by 15% annually, oil imports from OPEC countries will increase 19%, and U.S. gross domestic product will decrease on average 0.52% each year.
