there was an article in one our local publications about how much electricity we use even when we're not doing anything - the author suggested going around the house and checking for the little glowing lights to see what is running - microwave with the clock, TV, cable box, DVD player, PC, printer, chargers, adapters, etc. I would hate to turn everything off and have to remember to plug it back in before each use. One suggestion was the multiple plug outlet which can be turned on and off with one switch. Chargers need to turn off automatically when the item is fully charged.
