When we spoke with T. Boone Pickens in October 2010, he was lobbying Congress to enact a plan to convert the nation's over-the-road trucks to natural gas and thereby lessen the nation's dependence on foreign oil. Prices were around $4.00 mmbtu then. The March 2012 contract settled at $2.425 and still no action. Mark Fisher, our February 2011 feature, says eventually the U.S. will have to wake up and use the natural resources it already has available. Here, we look at the top 10 natural gas producing countries and compare that to their consumption rates and proven reserves. Source is the CIA Factbook.
