What? Per square whatever flat screens use a fraction of the power of CRTs.

When comparing a 15" LCD monitor with a 17" CRT monitor (which has an equal amount of viewing area), the LCD monitor used 55 watts less when operational (25 vs. 80) and 2 watts less when in standby (3 vs. 5). LCD screens also consume less power when returning from standby mode than CRTs.
For the same area an LCD TV uses about a quarter of the power of a CRT. LED/LCDs use only about 2/3s the power of older LCDs.

My LED/LCD would do PVR if I could be bothered to plug in a genuine USB 2 memory stick or HD. So I don't need a video player either. That's got to cut down power consumption too. Although not watching TV also cuts down on power consumption even more, an option I seem to take quite a lot these days.
It's surprising how many USB 2 memory sticks are not fast enough to really be USB 2.
