How does the energy use of a plasma or LCD TV compare to the older cathode ray tube designs?

    It is safe to say that LCDs use the least energy (77KWh), but recently LED displays are becoming even more efficient and will soon replace LCDs (estimates show around 50% less energy is used compared to LCDs). Cathode ray tube (CRT) displays are second in the list (123KWh), while plasma tvs use the most energy (441KWh).
