Energy Consumpution: LCD, Plasma, CRT, Projector

[Anhslaught]

So....title.

In general, what wastes more energy? LCD, Plasma, CRT, or Projectors?
Rank from least to most.

I'm just wondering because my brother came into my room. I had my LCD on and he was saying, "this TV is hecka hot!". Honestly....I feel the heat but it wasn't THAT hot.

So I said, "Well its not as hot as the CRT I gave you and it saves more electricity." He says, "I don't like your TV". I'm like, "ok......"
His projector is a lot hotter than my TV, when sitting next to it, you can feel the heat blowing in your face. So I was just wondering, if Projectors waste a lot of energy, or is it just hot air?
