These days, people really are taking coals to Newcastle. That flow is part of a vast reorganization of the global coal trade that is making the United States a major exporter for the first time in years — and helping to drive up domestic prices of the one fossil fuel the nation has in abundance. Rising worldwide demand is turning American coal into another hot global commodity, with domestic buyers having to compete with buyers from countries like Germany and Japan.

Great Britain, the country that used its vast coal stocks to pioneer industrial development in the 18th century, has become a major coal importer in recent years, its own industry moribund. With Newcastle-upon-Tyne once being the center of a rich English coal region, the phrase “hauling coals to Newcastle” was a cliché describing an absurd economic proposition.

Nowadays, however, coal arrives regularly at the Port of Tyne from suppliers in the Baltic and South America. American coal goes to other English ports at rising rates; figures from the Commerce Department show that in 2007, United States steam coal exports to the United Kingdom increased by 53 percent and coking coal, used in steel-making, by 20 percent, compared to the previous year.
