We already have a rule about keeping lights off. If anyone leaves a light in their room I take the bulbs out for a week. We had already switched to flourecent several months ago. With it being so warm out and with the a/c off I don’t use the oven much because it heats up the house. But I use the crockpot ALWAYS! It’s like my oven but much more efficient. I also keep the computer off. Expecially the monitor. We do not have a flat screen and you won’t believe the heat the older monitors can give off. We did use the a/c some while hubby was home on weekends. He’s use to his nice cool a/c in his truck.
