There's a boom in natural gas production in the United States, a boom so big the market is having trouble absorbing it all.
The unusually warm weather this winter is one reason for the excess, since it reduced the need for people to burn gas to heat their homes. A bigger reason, however, is the huge increase in gas production made possible by new methods of coaxing gas out of shale rock formations.
Since the Arab oil embargoes of the 1960s and 70s, it's been conventional wisdom to talk about American dependence on oil from the Persian Gulf. But the global oil market has changed dramatically since then.
Today, the U.S. actually gets most of its imported oil from Canada and Latin America.
And many Americans might be surprised to learn that the U.S. now imports roughly the same amount of oil from Africa as it does from the Persian Gulf. African imports were a bit higher in 2010, while Persian Gulf oil accounted for a bit more last year.
The U.S. is facing a growing surplus in natural gas. Renee Montagne talks to Amy Myers Jaffe, of the Energy Forum at the Baker Institute at Rice University, about the glut. She expects some consolidation in the industry.
America's reliance on coal to produce electricity has declined by more than 20 percent in recent years — but in 2011, the U.S. exported coal at a rate not seen in 20 years, according to the AP. And much of the new surge in coal exports comes from Asia and Europe.
Here's a rough guide to who's buying America's coal, based on the AP story:
South Korea: Up 81 percent to more than 10 million tons.
