Something rarely discussed is that the generation technology matters in your specific locale.
If you're powering it with coal, this is horrible. If hydro/solar/nuclear power, well it's still a big load on the grid, but carbon wise it's a small fraction of the footprint.
Of course you need to factor in where the power is actually coming from on your grid. And definitely factor in the time of day (are you charging overnight and actually using a higher carbon source, etc).
When you do the math on this Hummer on the cleanest sources, it's still far cleaner than even a small ICE engine. Even though I still hate it :)

If you are powering with hydro/solar/nuclear then you are consuming electricity that could otherwise be used to reduce the load on a natural gas power plant somewhere else
