What uses more power (CRT, Plasma, LCD)

[steppinthrax]

Pretty much thats the question.

I imagine size matters i.e. a 42" LCD uses more then a 36" LCD

Also how much power (watts) typical for each.

It depends on the model. Look up the product manuals online and look at the power consumption ratings to get an answer (hopefully if they were close to being accurate in their manual). A while ago I did some comparisons of CRT vs. LCD displays for Sony in particular and the results were pretty similar going off the manufacturer specs.

Looking at the manuals for Plasma can be misleading. A 50" Plasma might list 630Watts but plasma only uses a % of that since energy usage is based on the brightness of the screen, resulting in widely different energy usage patterns over time. In general, a plasma probably averages around 40-60% of what is stated in the manual.

If you don't understand this, it is very easy to conclude that Plasma uses 2x the electricity of a comparable LCD when in fact, both technologies use nearly the same amount.

CNET did an article on this subject. From what I can tell, DLP uses the least, then LCD, then Plasma. There are a few models in each category that are more efficient, but for the most part, that is how it falls.

Good point. I guess "Kill-A-Watts" attached to properly calibrated sets would be the best way to really tell
