Do lights use more energy to warm up?
This week’s question comes from Susan Fiore:
> I was brought up to turn the light off when I leave a room, even for a few minutes. My husband says it costs more to turn it off and back on again than leaving it on if you’re coming back soon.
> So which is right? And is it different for florescent, incandescent and halogen?
