Ever wonder how much energy your lamps use? How about your television? Your computer? Want to save some money?
Just plug the Kill A Watt into an electrical outlet then plug anything you want to measure the power consumption of (TV, refrigerator, lamp etc.) into the Kill A Watt and use the thing you are measuring normally.
After a few days check the Kill A Watt’s display and write down the information you see when each button is pressed then it’s time to do some math. The Department of Energy has a good explanation of how to translate the information from the Kill A Watt into dollars and cents. The knowledge you’ve just gained may help you save some money.
Take a look at the video below for more about how the Kill A Watt works.
