I'm surprised. I really have to doubt that a Plasma or LCD TV uses more energy than a similar sized CRT TV. I know my LCD monitors use much less power than the old clunky CRT type did.
Large CRT or CRT-based projectors use the most, followed by plasma (believe it or not) and other projectors, with LCDs consuming the least energy.
We are upgrading to LCD's for every screen in our home as the old monitors and TV's bite the dust. So far we have 17" and 19" LCD monitors and a 26" Sharp Aquos LCD HDTV. We love them all. The picture, the small footprint, there is no downside. These things are going down in price at a jaw-dropping pace. Like you, I doubt they suck more juice than a CRT, but we might be using them more!
