Sorry for those who didn't see it was a shell and for Bardal in particular. The way of arriving at the result however facilitated its detection ...
If everyone understands that running electric with its own renewable current is the TOP and that driving with fossil current is a dead end is already a lot.
Until recently, a large number of people, even highly educated and normally having access to scientific reasoning (what DID67 call a chestnut !) jumped on their chairs like goats screaming Electric, Electric, Electric, without ever wondering what was behind the outlet. If this number of people is reduced, hallelujah (3 times)!

And yes, a large number of people still believe that because the French current is produced for 3/4 with nuclear power, the tri-color EVs could run with a current reduced in CO2.
It is of course tempting to use a belief to have fun, but the reality is quite different because France is not electrically isolated from its European neighbors. The French electricity network is very interconnected with the rest of Europe and that's good for our security of supply.
The intellectually bearable minimum would be to take the value of European CO2 / kWh, or 460 g / kWh. With this value our ZOE at 20 kWh / 100 km spits 92 g of CO2 / km (yes, per km )
It is not glorious, to provide a much better service we have cars that obtain the same score, whose overall environmental impact is lower and which do not need new and ruinous infrastructure to drive.
But true reality is much worse ... reality which is constituted by the relationship between a fact and its consequences.
EDF does not shut down its nuclear power plants during "slack" periods of French electricity consumption, but it does not throw the current into the river. This current is sold to our neighbors who, in passing, integrate this "low carbon" current into their national consumption mix.
Si Bardal managed to convince millions of French people to recharge their EVs during off-peak hours, what will happen?
The answer is simple, there will be even fewer kWh "exported" than kWh consumed for recharging.
This is easy to understand ...
We can believe that our neighbors deprived of our current will rush on the candles, but in reality, they will put coal in their plants, I mean by that they will activate their means of production and unfortunately not the greenest ...
And the current delta product to recharge our red white blue EVs will have a CO2 content far greater than the standard European mix.
And here, it is not more complicated to understand ...
We can extend the reasoning to any time of the day on any day of the year. Electric consumption of EVs will be a new consumption (the great dream of EDF) and depending on the case, it will reduce our export capacity or increase our need for imports, which will lead to the production of "dirty" current outside our borders. . And everyone knows that CO2 has no borders.
This is why we can say, even if it is not a pleasure, that today EVs run on coal ... even if we close coal power plants in France
The only way to get out of it in the medium term is to reduce the need for energy to get around, and it's not by weighing down heavy cars that we're going to get there.
Christophe is on the right track, his ULM automobile (not necessarily electric for that matter!) Which could consume 6 to 7 kWh / 100 km, the equivalent of 2 l / 100 km, would be a reasonable route and in the same electricity production environment, it would make 30 g of CO2 / km.
Those who think that the French will not accept the downsizing of their dear car probably ignore that necessity rules ...
And if it is necessary that this small, weakly motorized and aerodynamic vehicle (the three characteristics must be combined) be electric to get it adopted ... why not!
