Every time I fly at night near a major city (LA, NYC, Dallas) I think that I should be in the light bulb business. Or at least the electricity business. There are millions of lights on all night long in a big city. Seems like a waste to me.
They already have enough problems with crime and accidents, don't they?
Still, I'd imagine turning off even 10% of them would save enough juice to make the switch from incandescents moot.

True, but most accidents are from stupidity and poor driving, not lack of lighting. Plenty of crime during daylight hours.
