Having grown up without air conditioning, I remember the days when it was important to turn off lights that you weren't using—not merely to save money, but because lights made the room warmer. One advantage to the trend toward fluorescent and LED bulbs is that they don't do that so much.

On the other hand, I don't want incandescent bulbs banned, because sometimes you want that heat. I can keep my composting worms from freezing on a cold winter's night by simply turning on a light under their coop. If it had an LED bulb, they'd freeze to death.

The new, highly-efficient incandescent bulb developed by MIT won't help me with that problem. Nonetheless, I'm glad to hear about it, since (1) it can be cheaper than the flurescent and LED bulbs, (2) it's safer, and (3) it gets the colors right.
