Assuming only 3 hours a day at about 300 watts operation, that's around one kilowatt hour per day, if in 365 days you only used $24 worth of electricity, the per kilowatt hour price would have to be $.065... who on earth pays only six and a half cents per kilowatt hour? 5 hours operation would mean 4.4 cents per kwH.
Either you were misled, or your TV is much more efficient that any other 50" plasma on the planet, or electricity prices are artificially low where you are.....

Your numbers do not match Panasonic's numbers for their 50" Viera S30. Remember, plasmas are seldom listed with average power numbers -- they nearly always list max power draw. That's not fair because power draw fluctuates with on screen brightness with plasma (average ≠ max). LCD, on the other hand, has very little power draw fluctuation (average ≈ max).

  I wouldn't expect realistic energy use numbers from a manufacturer any more than realistic fuel eff. numbers from the auto manufacturers!
  But to be fair: so you're saying that a plasma screen doesn't often use the max power?
  Also, power prices in the US do seem to be lower (artificially so, I might add) than in the rest of the world. I'm in NZ.

    Actual power draw with a plasma display depends on program material.
    
    However, plasmas are rated at the max power draw. This is based on a completely white screen (this basically represents "full on" mode). So the question is, how often when a display is in use do you have a completely white screen?

      Not only that, but it also assumes that brightness and contrast are at max levels. If you calibrate your set (and you should), the levels will never be at those max settings. Todays plasmas usually consume less energy in a typical situation than LCD/LED types.

        That's what salespeople and fanboiz are for.
