Thanks for making this information available. It has been very difficult to find any figures on the potential energy savings of the differnt tv options. Sorry for my ignorance but is 2-4 times less energy equivalent to saying 50%-75% less energy? Thanks again

Very true indeed, but I am guessing that a 40in LCD uses less power than a 20in CRT. That being said, 40in of TV also uses a lot of materials, weighs more for shipping, and leaves more material at the end of it’s lifetime.

It should be mentioned that size counts too, and the temptation is to buy bigger and bigger as they become more affordable. One does not help the environment by replacing a 20 in CRT TV with a 40 in LCD, for the area increases by a factor of 4 and energy consumption goes up with area.
