Δεν βγαινει έτσι εύκολα το κόστος, αφού όσο καταναλώνεις περισσότερο στην ΔΕΗ, τόσο ανεβαίνεις σε...κλιμάκια υψηλότερης χρέωσης! Επίσης για τις νεες πλάσμα της πανασόνικ μου ειπαν πως ...όταν εχεις μαυρο στην οθόνη έχεις σχεδόν μηδενική κατανάλωση, οπότε η συνολική είναι κάτι σαν μέσος όρος!

Οι CRT καταναλώνουν πολύ, μήπως ξέρει κάποιος;
Testing TV power consumption is easier said than doneFortunately, you can cut the power consumption of any TV if you calibrate it or simply reduce the brightness and contrast. This is also a good way to improve your TV's picture for a more detailed, cinematic effect. (TVs come from the factory with their brightness jacked way up, so they'll stand out on a brightly lit showroom floor — but that's probably not what'll look best in your living room.)
Και μετρήσεις από κάποια μοντέλα.... http://www.crutchfield.com/Learn/learningcenter/home/TV-power.html?page=2The objective is simple: Test the power consumption of TVs in a fair and consistent way that reflects how TVs are used in the real world.
But today's TVs come in several different flavors (LCD, plasma, DLP, etc.), each of which uses a different method to generate a moving picture. Moving pictures present a television with a dynamic signal that varies the set's power demand in step with the variations in color, contrast and motion. A static test pattern would make the test easier, but no one in the real world watches test patterns for fun (we hope).
All of these variables make it difficult to devise a fair and consistent test method. This partly explains why it took the electronics industry and ENERGY STAR authorities a long time to settle on the new 3.0 standard for power consumption testing.
.... Δεν μου ανοίγει και η σελίδα για να δούμε την μεθοδολογία που χρησιμοποιήθηκε.
το test γίνεται σύμφωνα με το new 3.0 standard της ENERGY STAR...από κει και πέρα δεν ξέρω...δεν ήμουν εκεί...:nounder:For the sake of consistency, we use the same source component (Denon DVD-1920 DVD player), the same signal path (HDMI, 1080i), and the same video clip for each test. A clip from the Will Smith movie I, Robot was selected for its visual variety. Each TV's picture controls (for color, brightness and contrast) are left at their "factory default" settings.
To make sure that power line fluctuations didn't skew the test results, we plug everything into a PS Audio Power Plant Premier power stabilizer.
To take the measurements, we use a machine recommended by our friends at CEA, the PLM1-LP Single Phase Power Multimeter, manufactured by Electronic Product Design, Inc. It's extraordinarily accurate when measuring standby power, as it's capable of measuring power as low as 0.02 watts.
The first test for each set is a 15-minute test in Power On mode while displaying the clip from I, Robot. Volume is set at 0 for consistency, and because volume settings have little or no effect on power consumption. The power consumption readings are fed to a Dell laptop computer at 2-second intervals, and the results are averaged. Next we test Standby Power for 15 minutes.

Νομιζω οτι η φωτογραφια ειναι ενδεικτικη της προοδου που σημειωθηκε στον συγκεκριμενο τομεα.
Βεβαια οι LCD με LED εχουν βελτιωθει και αυτες πολυ με αποκορυφωμα την Samsung 55Β7000 που εχει καταναλωση μολις 107 watt συμφωνα με το site παραπανω.
To qualify as ENERGY STAR must not exceed the following maximum OnMode power consumption equation: Υ = 0,245 Χ + 11.
Υ: Average OnMode Power consumptionni Watts and rounded to the nearest whole number.
X: The screen area of the product in square inches (foynd by multiplying the display width by the display height
For example, the maximum power consumption for a TV with a width of 27,9 inches and a height of 15,7 inches (437,6 square inches) would be: 0,245 * 437,6 + 11 = 118,21 Watts.
