  • Homes that Leak Electricity

    The low voltage power supply (the little black box that plugs into the wall outlet) is the culprit in some appliances. Cheaper models have high power losses, up to three Watts each. Higher quality, Underwriters Laboratory-certified power supplies already exist that have a three-way on-ready-off switch on the side.
