  •  Is coal "dirtier" than tar sands? (0+ / 0-)

    Of course, asking it that way assumes you can rate "dirtiness" with a single number.  As I understand, some kinds of coal, like what they mine in the Powder River valley in Montana, is 'dirty' mostly from the CO2 but not much else.  Other coals have a lot of sulfur in them, and other worrisome things.

    That said, how dirty are the oil and petcoke from tar sands, compared to getting the same liquid fuels from Venezuelan heavy crude (the likely replacement, in the short term at least) and burning some other kind of coal or whatever would be burned if the petcoke weren't a byproduct that was sold at giveaway prices?

    We're all pretty strange one way or another; some of us just hide it better. "Normal" is a dryer setting.
