If you mean someone is burning coal upstream, I suppose so, but the
idea is that big centralized power generation is both cleaner and more
efficient than most vehicles, so if the resulting consumption is
clean, it's a net winner.

Y'know, I don't get it, if you asked anybody five years ago what would
make sense for vehicles when oil reached $100/barrel, they'd have said
all sorts of alternatives could come online at those prices. Maybe
even hydrogen.
