Evil shale-gas fracking corporations slash U.S. carbon footprint

Don't you hate it when the market forces changes in energy consumption that bureaucratic bullying could not?  Citing a government report, blogger John Hanger reports:

After the first quarter, the USA's 2012 [carbon] emissions are falling sharply again and may drop to 1990 levels, or just slightly above that important milestone, according to data in EIA's latest Monthy Energy Review.  .  .  .  [T]he shale gas revolution, and the low-priced gas that it has made a reality, is the key driver of falling carbon emissions, especially in the last 12 months. . . .  Shale gas production has slashed carbon emissions and saved consumers more than $100 billion per year.  Truly astonishing!
