The Christian Science Monitor has this article on why the United States is importing more coal now than ever.
The article says in part:
"Coal-fired power plants along the Gulf Coast and East Coast have long imported coal by ship in small amounts. But with transportation costs and the price of low-sulfur coal from central Appalachia and Wyoming rising, US demand is soaring for coal from South America and as far away as Indonesia.
Leaping from 9 million tons to 30.5 million tons in the past six years, US coal imports could jump to 40 million tons this year, government analysts say. And that trend is accelerating as demand for low-sulfur coal grows following last year's federal Clean Air Interstate Rule, a mandate for big cuts in sulfur dioxide emissions from power plants in the eastern US.
At the same time, US coal exports are declining sharply. If present trends continue, the US will be a net importer of coal by 2013, according to the Energy Information Administration of the US Department of Energy. Still, most analysts see little need to worry since vast US reserves mean the US is unlikely to become dependent on overseas coal."
