For those interested in this, Wesabe just announced a partnership with WattzOn. You can read more about it here:

If I'm reading their announcement correctly, they'll automatically calculate and track your electric costs for you, based off your bank's utilities bills. Or something? Maybe
Marc can add some details?
They haven't launched the actual service yet, but hopefully it'll enable better awareness of energy use and conservation.
