[GreenYes] Re: mercury from fluorescents

I don't think John was saying that using CFLs is a bad thing, only that you need to pay attention to mercury.

If you consider the large increase in CFL market adoption since 2005, and that as bulb adoption rises the total Hg emissions associated with CFLs rises and the Hg from coal (assuming it is displaced) declines, CFLs become an increasing share of total domestic Hg emissions. This is a likely outcome, and one that should be planned for now. Longer-lived bulbs, lower Hg bulbs, and proper collection would all contribute to solving the problem. I don't know enough about the trends in market share and product formulations to know if you could sufficiently deal with the Hg issue with no collection.

And then the cost of what happens when you don't use fluorescents,
and the coal use jacks up 30%?

Goes back to some of the systemic issues you raised recently, yes?
