Technology: Kill-A-Watt

Cut down on your electricity usage and costs by finding out what appliances are actually worth keeping plugged in. Connect your appliances to the Kill A Watt, and it will assess how efficient they really are. You can calculate your electrical expenses by the day, week, month, even an entire year. Also check the quality of your power by monitoring Voltage, Line Frequency, and Power Factor. 

Contact your local library for availability.
