Locally, there was a radio station running PSAs to tell people to unplug their 
cell phone chargers "To save the environment".

I was very tempted to call in with some envelope calculations on the energy 
expended to send out the PSAs vs the energy saved.

It's not easy being green, but it's easy to LOOK green.

Hi:

For small (say under 5 Watt) loads the old wall wart has bit the dust
(at least in California) because they waste power.  The new wall warts
don't use mains frequency transformers, but rather transformers running
is kHz frequencies.  You can tell because they are much smaller than the
old ones and much lighter as well as working on any mains voltage and
current in the world.

Have Fun,
