edf/engie would only be able to 'steal' our Zoé's electricity if (1) it was plugged in at the time, (2) we had a Linky (unfortunately, that may be coming). In any event, this is extremely unlikely since we charge her up during heures creuses ('off peak') when it is extremely unlikely that the grid will be overloaded. Also, bear in mind that here (1) nuclear provides 2/3 of electricity, (2) we are linked in to the European grid. It would be a riskier proposition in England (UK imports about 7% of electricity, even more in England, and no longer benefits from the EU grid). Anyway, this thread has completely lost the plot: Our Zoé's 'fuel' costs €2-3 per 100km. Our Focus diesel costs about €8 per 100km, near enough 4x.
