How Much Greener Are Rechargeable Batteries?

I just read a short article in Wired - 16.11 which asks "Am I doing terribly wrong by the planet if I use alkaline batteries instead of rechargeables? I mean recharging requires power, right?"

I've always just taken it for granted that rechargeables would be more environmentally friendly and never really put a great deal of thought into how much more green they may or may not be. According to this article, a 2007 study by Bio Intelligence Service (sponsored by a French rechargeable battery maker) claimed that wearing out a single rechargeable battery impacts the environment less by a factor of 28 times. Makes me appreciate them all that much more!
