Chart Key

Model: The HDTV model name and manufacturer with link to review. Default sort is TV technology type arranged in ascending order of review date.

HDTV type: Flat-panel LCD, plasma, or rear-projection (RPTV). CRT models were excluded from this comparison because we haven't tested any recently.

Screen size: In inches diagonal. All TVs on this list are wide-screen 16:9 models.

Watts: Standby: Measured using the default, out of the box settings when the TV is in standby mode; e.g. with power turned off but the TV plugged in. Note: According to Extech, the manufacturer of the power meter we use for testing, readings of less than 1 watt may not be entirely accurate. We will still report the data the meter provides, but you should take results of less than 1 watt with a grain of salt.

Watts: Power on: Measured using the default settings when the TV's picture is on. Typically the default picture settings represent "torch mode," with high light output and correspondingly high power consumption, but some new models, such as the Panasonic TH-50PZ800U, default to a more-efficient picture mode when the user indicates a "home" rather than a "store" environment during initial setup.

Per square inch: The "Watts: Power on" result divided by the screen size of the TV in square inches.

Score (overall): A rating of Good, Average or Poor is assigned to each TV according to the "Watts: Power on" measurement. The top third of the TVs on this chart, currently models that consume below 208.202 watts, score "Good." The bottom third, currently models that consume above 280.562 watts, score "Poor." TVs that fall into the middle of the range score "Average." Note that the difference between any of these scores can be as little as a fraction of a watt.

Score (per size): A rating of Good, Average or Poor is assigned to each TV according to the "per square inch" measurement. The top third of the TVs on this chart, currently models that consume less than 0.2754 watt per square inch, score "Good." The bottom third, currently models that consume more than 0.3180 watt, score "Poor." TVs that fall into the middle of the range score "Average."

Annual cost: The amount of money the TV would cost to run over 365 days, assuming it's turned on for 8 hours a day and off for 16. We currently use the average price of energy in the U.S. during 2007, which is 10.6 cents per kilowatt hour according to the Energy Information Administration.

Notes: This chart contains 104 TVs tested by CNET for power consumption between roughly January 2006 and June 2008. For additional details on our testing methodology, check out How we test TV power consumption. Further power consumption data, namely wattage consumed in picture modes other than default, is available in the Juice Box at the bottom of every CNET HDTV review published since June 22, 2007.
