The Kill A Watt is what I have, gave me some very surprising info on electrical usage of some common household items -- especially when they are "off." Learned that the dehumidifier was the biggest electrical hog of all (and it was an Energy Star appliance!); that a 1950's era frig was an energy miser; that having the volume higher on the sound system made virtually no difference in electrical usage.
The Kill A Watt was instrumental in us reducing our electrical usage by 30% in achievement of one of our major conservation goals in 2008.
