Kill A Watt™ Meters

Have you ever wondered how much energy it takes to run your TV, computer or kitchen appliance?

Idaho Power has teamed up with libraries throughout Idaho to bring you an easy-to-use tool to help you find out.

Check out an Energy Efficiency Kit from your local library and learn ways to save energy and money. The kit features a Kill A Watt meter, a device that measures the energy consumption of appliances in your home, instruction for using the meter and tips for saving energy.

How does the meter work?

Kill A Watt MeterSimply plug the Kill A Watt meter into a standard, three-prong electrical outlet, then plug your appliance into the meter. The meter will measure the amount of power being used, helping you identify potential savings by either unplugging items when not in use or replacing the item with a more energy efficient model.

For instance, if you frequently leave your TV on all day for “background noise,” but no one is watching it, you can measure how much power it uses in a set period. From there, you can multiply the power used by your current electricity rate to see how much money you can save by turning it off when it’s not being watched.
