Sounds wonderful, yes! until you remember that 25% will include
industrial, commercial, street, & utility lighting (99.999% already
high-efficiency gas-discharge types), causing masses of light pollution
for our astrophotographers to grind their teeth over! The 30-odd 4X40W
fluoro battens on one floor of my office building would use more
lighting power than my whole street.
I think we're on different wavelengths again... :)
What we are talking about is installing say 6-10 CFL's in a domestic
situation, a very small proportion of which are used at all and those
for maybe up to 6-10 hours per day. As I understand it the accepted
domestic lighting consumption figure is more like 2% of a 'normal'
domestic bill (still looking for a current reference as I have to write
to my MP about this farce...) that would be in total around $2 per month
for us, before the lamp transplant... & compared to most people I know
we're relatively hungry...

Man, your power must be expensive over there!!!!
then ther'es the value judgemant one needs to make about disposal. is
it: "carbon in atmosphere bad... mercury in water table good..."???
