I always see "shipping from China" brought up as an argument against
CFL's too, but it's a pretty moot point in my opinion. Last I looked
I'm pretty sure I saw a "Made in China" label on the box of
incandescent bulbs as well. I'm quite certain they weren't made in
the factory buildings downtown in my city (they're all empty). So
there's shipping energy for everything. Besides, it's a problem that
can be solved by building a closer factory and not really a problem
with the technology itself.
