The Potential Gas Committee has issued its latest assessment of the country's natural gas supplies: "[T]he United States possesses a total technically recoverable resource base of 2,384 trillion cubic feet (Tcf) as of year-end 2012. This is the highest resource evaluation in the Committee’s 48-year history, exceeding the previous high assessment (from 2010) by 486 Tcf. Most of the increase arose from new evaluations of shale gas resources in the Atlantic, Rocky Mountain and Gulf Coast areas."
Not bad ...
