The extreme case would be e-Ink based devices, which have very low idle 
power consumptions, but the trend with "web designers" is to use all the 
processing power that they can get their hands on, in order get the 
attention of jaded users, at a time when hardware is getting better and 
better at power management.  Low end gaming GPUs can have a power 
consumption change of 60 watts between a static picture and maximum 
animation, and CPUs may also vary by about that much.

I'd actually want this for accessibility and usability reasons.  For the 
elderly and people with more formal cognitive disabilities, the 
animation is distracting - its often meant to be - its there to get 
people to look at the advertising, rather than the editorial.

Actually, I'd also suggest the increasing number of pages that seem to 
be continually running scripts also has an impact on energy wastage.  I 
tend to see this in terms of hogging the CPU on a single core system, 
but, on a modern system I'm sure that produces a quite significant power 

This is all really a "web design" rather than an HTML issue.

that is no longer good advice, as archive address hiding may not work.
