Coal. Wyoming, the nation's leading coal producer since 1986, provides about 40% of America's coal through the top 10 producing mines located in the Powder River Basin. Most Wyoming coal is subbituminous, which makes it an attractive choice for power plants because it has less sulfur and burns at around 8,400 to 8,800 BTUs per pound.
