This comment is really special coming from a guy that in another part
of this thread posted a link to an article that used OPEC, officials
in India, and the secretary of state of MA as credible sources pinning
the high price of oil on speculators. LOL
I'm absolutely positive that everyone in that article was more qualified
than you are to comment on the subject in question.

As I see it, what will happen w/ CFL's is the same thing that currently
happens w/ incandescents -- when they burn out, folks will toss them in
the trash and that's it, no matter what the rules are. There will be a
small number of folks who will go to some extra trouble, but it will be
a minute fraction of the population.
Is the mercury in the average CFL more dangerous or present a greater
potential for environmental impact that does the (presumable) lead in the
solder of an incandescent lamp?
Are we simply trading one hazard for another to save a few kilowatts?
I did my work in an older Usenet posting, which can be turned up by
Google by pasting this (split into 2 lines by my Unix shell account
There I showed calculations indicating that replacing a 60 watt
incandescent with a 15 watt CFL for 4,000 hours, if done in a location
where saving electricity saves burning of coal, saves burning of 77 kg of
coal (514 KWH of chemical energy). I post there assumptions of 35%
combined generating and transmission efficiency.
In my posting there, I do cite the Wiki article on coal, and also:
(indicates that 77 kg of coal has 5.4 to 18.5 mg of mercury)
(indicates that "median coal" (my words) with 514 KWH of chemical energy
has 14 mg of mercury.
So, if half of our electricity comes from coal, replacing a 60 watt
incandescent with a 15 watt CFL reduces mercury pollution by 7 mg on
average. Average CFLs have about 3-4 mg of mercury.

"They" removed the mercury from dry cells (batteries). Now it's CFLs (compact
fluorescent lamps) turn to be the poster child of a Good Idea<tm> with a
BAAAAD environmental impact.
How much mercury is in the average CFL? How much REAL damage can they do if
introduced into the general waste stream and deposited in a MODERN landfill?
If they are <ahem> PROPERLY recycled, what happens to the mercury?
If the D.C.Droids can legislate 35mpg and ban the 100w and 75w incandescent
light bulb, why do they not address the building "threat" of discarded CFLs?
Fact is you can find CF's that don't take a minute to get usable light.
Some are nearly instant on. The only filament lamps I use at all are
maybe a couple I haven't bothered to change that I leave on for 5-10
minutes at a time only.
I find it grating to read posts which make fun of federal lawmakers. I
wouldn't want to spend more than 10 minutes of every year sitting in the
halls of congress. I know it's a madhouse, but walk a mile in their
shoes before you paint them all with the same brush.
Believe it or not, letting people do what they damn well please doesn't
work in this country.
