Maps show rapid increase in amount of crude oil shipped across U.S. from 2010 to 2014

Maps released this week by the U.S. Energy Information Administration chart the drastic increase in crude oil shipment by rail from 2010 to 2014, which is leading to a dramatic rise in derailments, Christopher Ingraham reports for The Washington Post. The U.S. moved one million barrels of crude oil per day by train in 2014, a significant increase from the 55,000 barrels per day moved in 2010. (EIA map: Crude oil shipments by rail in 2010)

"It's worth keeping in mind that both railways and pipelines deliver well over 99 percent of their crude oil safely and without incident," Ingraham writes. "But due to the sheer volume now moving across the country in one form or another, accidents are inevitable." (Crude oil shipments by rail in 2014)
