i guess you meant to say flat panels tv like plasma which they claimed consumes more energy than CRT...
but i think its true, as time go by, these tv will consume less energy as technology advances.
I just read that panasonic and pioneer 1080p plasma that just came out a few months back that much better black level and higher contrast ratio. In the range of 2,500:1. Yet, it also consume less energy than previous models. Pretty cool huh.
