Well, maybe.

But consider: Replacing how many 100 W incandescent lamps used 6 hours
a day with 25 W equivalent brightness compact fluorescents will it take
to same more energy than used by all those appliances in the house with
standby modes?

10? 5? 2? 1?


Ah, but how much extra energy went into the _manufacturing_ of these 'energy
efficient lights compared to incandescent lamps? I've not seen any figures
and I wouldn't really like to guess, but its got to be more; probably by a
factor or two or three...

Yes, but how does it compare with the electrical energy cost over the life of the
lamp (100 kW-h for a 100 W 1000 hour incandescent lamp)?
