July 31, 2008 GOOD Magazine have you wondering how much power your HDTV consumes? Try the Kill A Watt.

Simply plug any electrical device into the Kill A Watt and the LCD display will tell you the drain of the device in Volts, Amps, Watts, Hz, VA or kilowatt-hours (kWh) - and calculate your electricity bill by the day, week, month or year based on your energy provider's price per kWh.
