(1) As instructed by media propaganda, at 8 PM I turned off all lights and unplugged my computer and stereo etc. Then, since the apartment was dark, and the weather was warm (in the 50s), I decided to take a walk. During the walk I triggered four automatic porch lights as I passed near them. I don't know the wattage of the lights, or how long they stayed on after I passed, but I wouldn't be at all surprised if in their time on they used more energy than I would have if I'd spent the hour at home sitting at my computer.
