Much of the talk about a North American “energy revolution” and the United States becoming the world’s biggest energy producer before the end of the decade is predicated on huge discoveries of oil and especially natural gas in previously unreachable areas throughout the country. Indeed, through 2011 and 2012, natural gas was beginning to dislodge coal as the dominant source of electricity in the U.S. One year ago, natural gas and coal each supplies about 32 percent of America’s electricity.

But with the boom in natural gas came all the complications of commodity pricing, no less the logic of markets, investors, and traders in general. As cheap as $2 dollars per million British thermal units only a year ago, natural gas now costs more than $4 per Btu.

This has created a situation, as of March, in which coal, while supplying less U.S. electricity than it ever has, is still the primary source of America’s electricity (over 40 percent). Furthermore, U.S. coal companies are incredibly interested in exporting coal to emerging markets like China, who still rely on cheap energy sources, regardless the environmental impact.
