Coal Costs U.S. $500 Billion Per Year: Study

But while advocates often tout the inexpensiveness of coal, a new study reveals that the substance may be costing the U.S. up to $500 billion per year. So much for cheap coal.

Harvard professor and Huffington Post contributor Paul Epstein, M.D., M.P.H., has just announced the release of a new study in the Annals of the New York Academy of Sciences entitled "Full Cost Accounting For the Life Cycle Of Coal."
