I think it is safe to say that the number of people buying LCDs is growing. Only when somebody is interested in buying a new computer do they think of buying a LCD. Still some people end up buying CRTs because they are cheaper. Majority of the people are not interested in discarding their old working CRT monitor to buy a LCD one following the thumb rule - If it ain't broke, don't fix it. So the number of CRTs present is diminishing at a slower rate. Most of the people in India still use CRTs. So the amount of power consumed by all the computers would be lessened as a whole. Looking at the bigger picture, "measurable" amount of power will definitely be saved.
I wonder if it makes any positive impact to use LCDs. As screen sizes become bigger, these benefits get negated. A 21" CRT TV consumes 70W of power. A 32" LCD TV consumes 170W of power. As people switch over from CRTs to LCDs, they even go for bigger screens. Imagine how much power the 42", 52" LCD/Plasma TVs must be consuming.
