These emissions are already so miniscule that any attempt to reduce them further will cost far more than the cost of any health problems they cause. There is absolutely no evidence that in their current concentrations they are causing any health problems at all.I would certainly be willing to pay an amount equal to the costs of having mercury and toxic air emissions: increased health costs, lost productivity costs, clean up costs, etc. Would any rational person disagree with this? Do you?How much are you willing to pay for "limited mercury and toxic air emissions?" $1000/yr? $10,000/yr? $50,000/yr? If you claim "yes" to the last one, you're a god damned liar.I won't apologize for wanting my kids to have limited mercury and toxic air emissions but it was the trend to frac'ing and the resultant increase in natural gas production that is killing coal prices. No liberals required.If you read article CSX and others cite FEDERAL REGULATIONS.
I agree, but it's still dirtier than solar, and if the current costs of producing solar keep declining, it's cheaper in the long run. Solar of course isn't going to replace the energy needed for running the big mills and smelters overseas, and that market will be buying more coal if or when manufacturing picks up.
