The rest of the world lags the United States in fracking for a number of reasons, writes Jeff McMahon at Forbes magazine.
McMahon: "Shale gas deposits have been found in Poland, Argentina, China, Great Britain and other countries, but only the United States has fracked its shale gas into a national energy boom.
"That’s not for lack of will abroad, according to energy experts gathered Friday at the University of Chicago: it’s because of political and economic circumstances that fostered hydraulic fracturing here while dampening its spread overseas."
