^^^^^^^^^^^^^^^^^^
Do you have any kind of ballpark figure of the efficiency of the
distributionn grid, from the generator terminals to the average consumer?
I would like to know this, because when people talk about the cleanliness
of electric cars, they frequently forget that there is CO2 coming out the
stacks at the power plant. Steam generation plants run MUCH cleaner than
automotive IC engines, but how much of that advantage do we lose in the
grid?


Nope, I don't have it, but I've seen it all other the place on the Web. I'd
have to go looking but you probably can find it yourself. There's quite a
range, depending on where you are in relation to a generating station and
how the network operates, but you probably can find some average figures.

Let me know if you draw a blank. I've been bouncing all over the Web on
energy related issues lately but I think I can come up with it.
