I have always wondered though what is the energy required to manufacture the two different bulb types. An incandescent one is quite simple and only has a few simple materials, it may use more energy to run, but the only thing that matters in the big scheme is how much energy does a single light require from its birth to death (if you get what I mean). Flourescent lights require a lot more manufacturing equipment and more dangerous chemicals, probably more energy to make a single unit, but if they last longer this is averaged down significantly. Hopefully someone has looked at the "big picture" and haven't just made a decision base purely on the energy consumed while the light is being used, otherwise we just end up using more energy in the end...not a good idea!
