Reducing home electricity use is one of the single most effective ways to lessen your environmental impact while saving money on utility bills. And a simple energy meter like the Kill A Watt EZ can help you pinpoint which appliances and devices are your home’s biggest power consumers.
Knowing which household items are energy hogs helps in several ways. It lets you avoid unnecessary usage of the biggest offenders, and it can help you decide whether replacing an old appliance with a new energy-efficient model makes sense. Finally, it can help you identify simple fixes needed to help devices operate at peak efficiency (like an unusually power-thirsty refrigerator that needs a new door seal, or an AC that needs a tuneup).
There are a number of home energy monitors on the market these days, but the Kill A Watt EZ remains one of the most effective and user-friendly options. Users simply plug it into a wall outlet, then plug an item into its receptacle, and the LCD display shows power consumption (in kilowatt hours), voltage, and line frequency. The Kill A Watt EZ is designed for North American 120Volt AC use, and the manufacturer states that measurements are accurate within 0.2%.
Advantages of the Kill A Watt EZ over the basic Kill A Watt model include a battery back up function, and the ability to program your own electricity rates per Kwh (as noted on your power bill) to calculate energy costs.

The Kill A Watt EZ Electricity Meter is available from Amazon for around $25. Bonus tip: a short extension cord like the Liberator Power Strip Adapter makes the Kill A Watt much easier to use, especially under desks and behind furniture.
