With the fuel unable to compete in most places with natural gas, nuclear, and renewables, the mining and burning of coal is increasingly toxic economically as well as environmentally. Coal mines are becoming "stranded assets" — unlikely ever to pay off the costs of their development. The risks for financiers are becoming too great.
