For additional fun numbers, consider rail - the one anecdotal data point is that the turbine that runs the *entire* MBTA subway system is equivalent to one engine of a 727 :)
I've yet to find good numbers on pure-electric cars, or rather, fuel consumption per kWh at the head end. I have been dismayed at how I apparently can't buy one in any case, because they only build enough to meet the CAFE quotas (and I can't quite justify an acpropulsion.com t-zero...) It's also kind of sad the extent to which VW TDI-based cars get better mileage than US-market hybrids, not to mention the mileage some of the european mini-cars get (the Lupo 3L comes to mind.)
727 is a spurious example; the last one flying was just taken off the line not because it was too old to be safe but because it was the least fuel-efficient thing out there.
fuel consumption per kWh at the head end
I too am dismayed at the lack of readily-available data on this sort of thing. I wonder if people believe electricity is clean simply because when it is USED you don't see smoke. I find it easy to believe in economies of scale at the generating plant, but I'd still like to see information.

...if you use it correctly. Or rather, correctly and without the intent to produce smoke.
I'm sure you've heard about how electronic devices are actually powered by smoke. If you let the smoke out, they don't work anymore :-)
