Each mine produces about 100 million tons annually. Combined, these two surface mines produce nearly 20 percent of the nation’s coal. Wyoming is the nation’s top coal producer, accounting for more than 39 percent of all the coal mined in the United States. Coal is used to produce nearly half of all electricity consumed in the country. Coal is the second largest source of revenue in Wyoming and contributed over $1 billion in taxes to state and local governments in 2012. Data Go Interactive
