Where much of the electricity comes from coal, CFLs actually reduce

I have seen this figure tossed about, but even after Googling AND
Yahooing, I can't find an original (or any approaching) an actual
citation. Anyone know where I ca get it, I'd like to see how it was
figured.
Start he
"Mercury emissions from power plants are considered the largest
anthropogenic source of mercury released to the atmosphere; about 48 tons
are emitted annually in the U.S.A. as a result of fossil fuel combustion,
mostly from coal-fired power plants."

And do the math.
Or
"Over five years, a coal power plant will emit 10 milligrams of mercury to
power an incandescent bulb, and only 2.4 milligrams to operate a CFL."
