Making Sustainability Metrics Fun
Should I discard my still-working standard incandescent bulbs and replace them with compact fluorescents, or wait until they die a natural death and then replace them?
There are several reasons to get rid of those incandescent bulbs and replace them with compact fluorescent lights (CFLs). Incandescent bulbs turn less than 5 percent of the electricity they use into light; the rest is wasted heat. Besides being annoyingly inefficient, this can increase summertime air-conditioning costs and present a higher risk of fire. CFLs, on the other hand, are over three times more efficient, meaning they put out the same amount of light but use one-third as much electricity; they also put out much less heat.

I've heard that the new light bulbs that replace incandescent bulbs are giving people migraine headaches because of the bright light they emit. Any comment?
Additional energy is expended when disposing of CFLs. They often must be transported to waste disposal sites (via individual autos) and the disposal itself requires shipping and dismantling. Since incandescents can simply be tossed in the landfill, how does the additional disposal energy of CFLs impact the bottom line?
Thanks!
