Chart key

Model: The HDTV model name and manufacturer. Default sort is by technology type, with newest reviews listed higher on the chart.

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: We no longer report standby power consumption on this chart. We still measure and include it as part of the Juice Box (see below), but since the majority of TVs we've tested in the last year have standby power measurements of less than 1 watt--below the sensitivity level of our measurement device--standby power results have been excluded from the chart.

Watts: Power on: Measured using the default settings when the TV's picture is on. Prior to the Energy Star 3.0 update in November 2008, the default settings were a sort of "torch mode," with high light output and correspondingly high power consumption. But since the update many new models have dimmer pictures and less power use in the default mode. See The Basics of TV power for more.

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 195.48 watts, score "Good." The bottom third, currently models that consume above 272.98 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 0.26 watt per square inch, score "Good." The bottom third, currently models that consume more than 0.31 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 5.2 hours a day and off for 18.8. We currently use the average price of energy in the U.S. during 2008, which is 11.35 cents per kilowatt hour according to the Energy Information Administration. These numbers were updated April 10, 2009.

Notes: This chart contains 150 TVs tested by CNET for power consumption between roughly January 2006 and April 2009. 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.
