Hidden Costs of Energy

I've recently been reading Hidden Costs of Energy. The book began by defining some necessary terms and explaining things like externalitities in simpler terms. It's continued by discussing the costs that are not accounted for in the market energy prices. I've found it really interesting how much is unaccounted for in the cost of energy that we pay for, that has been unleashed on the environment. Each year trillions of dollars in damages to the environment due to externalities are released. In 2005 the damages associated with only coal from the pollutants SO2, NOx, PM2.5 and PM10 alone added up to be about $62 billion dollars ($156 million/plant)! I honestly never would have guessed such a large figure! Although, the average damages per kWh is only 1.7 cents, which seems as though that is a fairly easily solved problem!
