Surely you
don't believe that's the only reason. Heck, I'd
personally never even considered where or how they were made. I just
look at the "100W worth of light for 12W of energy" part, and it's a
no-brainer.
There's the ROI aspect. I could perhaps see replacing end-of-life
incandescent bulbs with similarly-priced CFLs if the lifetime and
price were comparable. But it's downright foolish to replace a lamp
in a closet or stairway with a CFL "just because" where the lamp sees
probably less than 10 hours use per year. In that case, replacing
with the cheapest source of illumination, regardless of efficiency
makes the most sense.
Of course. Most of the lighting in my house is in fairly heavy use.
I've not replaced things like hall lights which are almost never used.
You can dispose of an incandescent by tossing it into
the trash. Not
so for CFLs--and I suspect there are some government subsidies spent
dealing with that problem.
There's that. Although, the one CFL that did die on me got thrown
into the trash. It seemed to go just fine. ;)
In an all-electric (we have no access to natural gas
and I won't
allow propane into the house) household, lighting accounts for a
miniscule portion of the energy budget. You'll get far more bang for
your buck by replacing the water heater with a well-insulated energy-
efficient model--or by turning down the heating thermostat a few
degrees during wintertime.
My power bill dropped by about $30/mo, but then there's a LOT of
lighting in there, and remember there's heat removal cost (year-round in
FL) as well as light generation cost. The still-functional incandescent
bulbs were put into a box, where they will stay until I sell them on
eBay in a decade or two. =)
Or by using a fan instead of central air conditioning
during the summertime.
Not here. With ~3.5-4kW worth of computers running 24x7, we run A/C
year-round. With how hot our part of Florida has become over the past
5-6 years, we'd probably still be running A/C year-round even without
the computers. It's unbelievable. That's the big reason we're trying
so hard to move back up north.
Or just get rid of your big-screen plasma TV...
There's that too. :) Thankfully I don't watch TV! ;)
