Actually, that brings up an intersting point. Is there any truth to the urban legend that actually turning on florescent lamps uses more energy than running them for an entire day. In grammer school, I had a teacher that would flick the lights on and off to get our attention, until she discovered that that was not green-friendly behavior.
I understand that the urban legend is just that. I suppose flicking lights on and off will burn them out sooner. CFLs do take a second to light up. I am not an expert in this area.
I looked at power usage for a year at a church. The bill went up dramatically when there were evening services, the main difference being the lights being on.
