Everyone seems to leave their tv's and other devices on standby. How much electricity are they actually using? What about your phone and battery chargers? How much electricity is used for each dish washing load or clothes drying?
This neat little gadget called a Kill-A-Watt will tell you exactly. Just plug it in between the wall and your device and watch the power used. This is a very easy way of monitoring your power usage and can actually save you money!
