    If you mean energy consumption, plasma is way down there ( in terms of efficiency). I would guess that projectors with a big bulb, i.e., front projectors, DLP, use next most. Surprisingly, my 65 inch CRT RPTV uses only 185 watts. A 65 inch plasma uses 700 watts.

    I'm looking for something with very low energy comsuption and still help protects the vision of the young ones. My TV is at work anywhere from 6 - 8 hours a day.

    Are those "typical usage" powers or maximums?

    Over the last 2 months I have seen two references that yes, the maximum power a plasma uses is more than an LCD panel, but in normal usage they are very comparable. The reason why is that a plasma only needs and uses power for the pixels that are lit up at any one time. An LCD must apply power to all of the pixels all the time.

    I can't answer your question. All I can say is that a lot of plasmas have fan cooling. FWIW here is what Panasonic lists energy consumption as for various sizes in the 7 series:

    37 inch ED: 225 watts
    42 inch ED: 290 watts

    42 inch HD: 357 watts
    50 inch HD: 480 watts
    65 inch HD: 695 watts
