2011 Harvard Study Found Full Cost of Coal Very High

Published in 2011, this study estimates, in a conservative manner, the full life-cycle cost of the US's reliance on coal for electricity. Its main finding is that the true cost of coal for electricity is between 9 and 27 cents per kWh (best estimate: 18 cents/kWh), considerably more than competently developed wind power. Taxpayers are paying this price, although it doesn't show up on our electric bills.
