natural gas produced from shale is actually responsible for spewing significantly more greenhouse gases than coal.
Even if it's true, I don't give a rat's behind. All I said was that if market forces (which also don't give a rat's behind about CO2 emissions) drive coal out of the market, then I have no problem with it.
And yes there are forces artificially driving the market. You'd be foolish to think not.
The EPA haven't caught up with it yet. Maybe because it is perceived as more green. Maybe because people have been bought off. But be warned, its next! Especially if nat gas is obtained via fracking.
