After electric power was generated in equal parts from both coal and natural gas in Q2 2012, according to the Energy Information Administration (EIA), numbers into Q1 2013 indicate coal met at least 40% of America’s electricity needs monthly since Q4 2012—with natural gas representing 25% during the corresponding time.

Coal imports in the world’s biggest coal-using nation surged by 15% in the 30 days leading up to April as cheaper prices abroad drew increased shipments—with Indonesia and the U.S. leading the way. Indonesia is No. 1 in thermal coal, while American coal maintains a robust global market share despite Washington regulations and natural gas competition.
