From Cnet which shows LCD consistantly lower in power consumption (as we all agree they are) the results however do not take into account Plasmas true ability to reduce power consumption according to the scene being displayed.......as displays were measured on for only one hour on one "normal"TV show........
I personally would like to see test numbers LCDvsPlasma on say a movie like "Pans Labyrinth"...

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.
Watts: Power on: Measured using the default settings when the TV's picture is on.
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 207.787 watts, score "Good." The bottom third, currently models that consume above 280.346 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 0.2733 watt per square inch, score "Good." The bottom third, currently models that consume more than 0.3164 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 2006, which is 10.4 cents per kilowatt hour according to the Energy Information Administration.
Notes: This chart contains 80 TVs tested by CNET for power consumption between roughly January 2006 and November 2007. 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.
