If you charge it by a diesel genny then yeah, obviously not very green. May I suggest charging via a gerbil powered flywheel. And if grid power is not available probably not a good choice which I never claimed it was.
I am not trying to say the battery power density is there yet for all machines but it's coming. Here is a link to a big toy

Then perhaps stop at a charger on the way, just as you would with a gas/petrol powered car. I am going out on a limb thinking you don't have this situation every week and going further out on a limb guessing you don't normally fill your car's petrol tank at home every night.
