If you were needing heat at the ceiling level of that particular room.
If it isn't summer and you're not consuming MORE power on AC to remove the excess heat. (Huge problem in the southern US)
If you're not in an office building where machinery and bodies already generate more heat than is needed.
Of course this is Canada. Four months of the year we can get by with no light bulbs at all. The rest of the year that "wasted" heat helps to warm our homes and is truly appreciated.
BTW the environmental damage of the Mercury and Phosphors contained in CFBs far outweigh the benefits of reduced power consumption. Especially in Canada where there is no plan or technology in place to recover the toxic elements.

Well, full of potential, perhaps, but not street-legal-not yet. I think for short jaunts in the city, they'd be okay. Solar is starting to come into its own, thanks to cheaper manufacturing and greater efficiencies and may supplement conventional sources of power. There's really no way (at least in Alberta) to sell the power generated by solar back to the Electric Company. They barely tolerate it as is..
As for CFL's, well, they're a good start. You can't really use 'em in lights that are dimmed, and I haven't dared to put 'em in my oven, and you can't really use 'em
that well outside as the cold makes 'em slow to start up. LED lights aren't practical yet ($50 a bulb? I don't think so). I was kinda looking at TATA's truck that runs on compressed air. Ugly, yes, but it does work. Now if they got a car that runs on methane, or maybe converted fast-food grease, and made enough of them, that would be a start. Instead of smog, the air might smell like french fries
Couple of thoughts. First these are recent technology batteries. The Energizer NiMH batteries I use in my camera claim thousands of cycles and 20+year life spans. However after about 30 cycles the charge holds about 10 days instead of 6 weeks. Are the 15 year life spans similarly exaggerated?
NiMH batteries are kind of funny when it comes to storing them fully charged as I have read that doing so over time reduces their ability to take a full charge on subsequent cycles. Also overcharging can permanently damage the batteries.
