Of course he knows this; that's implicit in his arguments. He's not stupid.

What he's saying, which I agree with, is that the use of CFLs, primarily
for *residential* lighting (not commercial, which as you point out has
already been using fluorescents for many decades) will result in a
massive upsurge in the amount of mercury in transit out there, some of
which will escape into the environment. This is the 900-pound gorilla of
CFL usage which isn't getting nearly as much attention as it should, and
makes the claims that Don K. and others have made about how much CFLs
will result in *reduced* mercury emissions dubious at best.
