Interesting tie to this - On the watt podcast #75 they discuss how the coal power plant reduction happened.

Lower heat content, lower sulfur coal was shipped in VS using 'local' higher heat, higher sulfur coal.

Thus lower sulfur emitted, higher CO2 emissions.

WHEEE!

Now I'll bet they wish they installed scrubbers (or whatever it is that captures the sulfur), and had "waste" sulfur to sell. Last I heard it was something like $900/ton.
