(Though is anybody really surprised that large TVs use a lot more current? Electricity consumption would, I imagine, be a function of the square of the screen size, meaning that even small increases in size result in large increases in power consumption. Which, also, is probably one of the reasons why small, wimpy-looking laptops have about twice the battery life of the larger, more-impressive-looking ones.)
Actually, I think you may be on to something there...
Actually, I'm wondering how flat-screen monitors compare with CRTs, in terms of power consumption.
They consume a lot less, apparently. (Doubly so if you need air conditioning to get rid of the heat a CRT puts out.)
Is that why small wimpy looking youths have twice the brainpower of their more athletic looking peers?
