My charger uses around 20 watts. So the cost of recharging 4 AA Eneloops will be under 2p. It's not free but it's not worth bothering about.

You have to take a lot of photos to offset the cost of the charger and batteries, and I don't know where the break-even point is. A benefit of using a standard format is that I also use the charger for my GPS, my toothbrush, my shaver, etc, so the cost should be amortised across all those things.
It's a lot less inconvenient with Eneloops (or other low-self-discharge brands) than with previous rechargeables, because they hold their charge. You can have one set in the camera and another set on stand-by, and the stand-by set will hold their charge well. You don't have to recharge them a few days before you use them.
On the other hand, being able to recharge them when you want, means you don't have to worry about going into the field with batteries close to dead. With non-rechargeable, you either risk missing a shot because the battery died at the wrong moment, or else stop using them a while before they die. When they do die, you don't have the inconvenience of having to buy more.
Basically, I'm not sure if Eneloops are cheaper for me, but I prefer them anyway.
