A high school algebra project first clued me in to the inefficiencies of incandescent light bulbs. After working out some basic calculations in the classroom, I was appalled to find just how much electricity these virtual heat-lamps devour (and how much more they add to electric bills) in relation to their fluorescent counterparts.
