The source of the electricity used for charging has the greatest
impact
on the true efficiency and emissions as everyone else noted. What
they
forgot to note is that EVs do not consume any energy during stops or
downhill grades, and recapture some energy during braking, both of
which
can further improve efficiency to a variable amount based on terrain
and
usage.

Planning the route and timing of your shopping trips does that too,
with any vehicle.
