Remember to turn the light off before you go to bed.

These kinds of pictures used to amaze me a few years ago, and in many ways they still do. But the more I've read about energy issues over the past two years I've started to comprehend the sheer wastage that exists all around us, and I suddenly see this picture in a different way. I don't want to get into a despairing rant about the coming energy/oil crisis, so to put it simplistically, this is what we're fighting for: just to keep the lights on.
