Coal Production in the United States – An Historical Overview, October 1, 2006 (19 pages, PDF)
“Energy from coal has been important historically in the United States for a broad range of uses. Coal today is used principally as a fuel for electricity generation and other industrial processes. Coal mining practices and technologies have become more productive through geographic changes in mining areas and increases in mine size to produce coal at competitive prices. Coal prices respond to occasional surges in demand and to regulatory requirements but, over the long term, have trended lower in real dollars.”
