My husband is always going around unplugging our AC adapters. Sadly, until I met him, I was completely unaware that many of these so-called "wall warts" continue to draw power from the grid even if the appliance they run isn't plugged in at the other end. My roommate and I left our phone chargers plugged in to the kitchen outlet 24 hours a day.
You can tell your wall wart is wasting energy if it's warm to the touch when your cell phone, laptop, etc. isn't charging. Most of the ones in my house are this wasteful model. There is a fix to this problem: manufacturers could install switches in them, but that would make them more expensive.
So in the meantime do one thing for the planet: unplug your cell phone charger, your laptop charger, your baby monitor charger, your battery charger, your ipod charger...
