The United States possesses the largest recoverable coal reserves in the world, holding more than one-fifth of the global total, with massive geological deposits distributed heavily across regions like the Powder River Basin in Wyoming and Montana, alongside major basins in Illinois, West Virginia, Pennsylvania, and Kentucky. Other nations with exceptionally massive proven coal deposits include Russia, Australia, China, and India, which collectively control the vast majority of global thermal and metallurgical coal resources utilized for international power generation and industrial steel manufacturing.
