This, incidentially, is probably why renault has several billion euros invested in electric automotion RnD - Napkin math indicates that the electricity demand from a total switchover to electric veichles,
- assuming nighttime only charging -
would produce a demandcurve for electricity that is very nearly flat, which would make EDF do the dance of joy nonstop for the next decade.

Granted, this is a fairly challenging assumption, but most (french) people drive a heck of a lot less per day than the range on the cars renault is offering, so as long as the economic incentives are there, most people should refrain from topping up charge while at work or similar sillyness.
