The other day I picked up the Kill A Watt EZ from Costco (mentioned in an earlier post for their recycling program with Gazelle) for $20. Being the type of person that doesn’t read instructions I ripped open the package and plugged the device into a three-pronged outlet. Unsure what to do next, I plugged a computer cord into the other side of the device (see the picture at right). It read 120.6 volts. Since I couldn’t figure out how to change it, I unplugged the device and read the instructions.

The Kill A Watt EZ allows the user to choose from several different settings, including kWh (for kilowatt hours), voltage, or cost – which depends on one’s electricity rate. One neat feature is the programmable electricity rate. Type in the rate you pay (ex. $0.10 per kWh) and the Kill A Watt will calculate the cost to power your device. This feature comes in particularly handy for devices that consume large amounts of electricity (such as flat panel TVs), especially when plugged in but not in use. In addition, when deciding whether or not a new appliance makes sense (and cents), use the Kill A Watt to determine the appliance’s electricity consumption.

While I’ve had the device for a few weeks, it has been more of a novelty. I’d like to use it with larger appliances, as well as the power strip that serves our entertainment center but that requires unplugging the strip and potentially losing any data.

Regardless of the device’s information, the status quo remains unless consumers take the extra step to assimilate the data garnered from the Kill A Watt EZ. The feedback provided by the device helps, but it cannot reduce consumption on its own. The only way to ensure savings for consumers is to go the extra step and either unplug appliances that draw power when not in use or reduce usage of devices that consume excessive amounts of electricity. Consumer behavior will change when information is accessible and economic benefits align.
