Re: Anyone moved to LED Lighting?

Dave,
Do you have any cites for those figures? Not that I doubt any of it but this
argument comes up and will continue to come up for the next hundred years.

OTOH: there is the personal economy thing and this seems to be the classic
main motivational force for the masses.

According to DOE figures, that 9% applies ONLY to residential electricity.
Residential accounts for about 1/3 of the total with industrial and
commercial accounting for about 1/3 each. Industrial lighting is about 6% ot
total industrial electricity and commercial lighting is about 12% of their
total. The latter two sectors have long used lighting that is more efficient
than CFLs so there's little to gain there (see the comparison in my earlier
post). This makes residential lighting about 3% of the total and even
assuming all of that is replaced by CFLs or LEDs, it means only a 2%
reduction. And, since electricity accounts for less than half of the carbon
we're putting into the atmosphere and only half of our electricity comes
from coal, the reduction is on the order of 1/2 of 1% (which is very much in
line with the UK study I referenced ealier and even that's very optimistic).
BTW, the generating plants that are quickly ramped up/down are mostly fired
by natural gas.
