The energy to fill the batteries has to come from somewhere, though.  I don't think solar will be enough. 

Why not? It is already enough. It is a matter of how many solar panels you need for your location, to cover let´s say 85-90% of the days. Rest comes from network, not worth to go 100%, as the last 10-15% becomes much more expensive.

As I've said before, no different than being a BMW, Mercedes or Fiat fan.

You`re not wrong.

Anyone who loves a product/person so much that they can see absolutely nothing wrong in what they do or they treat them as god like deserves scorn.

It`s like the almost cult like devotion to Trump by some christians.

The argument was for how to power it. Regarding on how to transport it, most charging will be done over night, where power consumption is very low. Together with self-production, I don´t foresee much of an issue on infrastructure. As an example, I expect to use around 2000kWh per year for the car. For the house itself, I consume around 3700, mostly during the day. So my night consumption will still be lower than my day consumption, meaning no need to reinforce infrastructure in this case. With 2 EVs things change a bit, but not much.

 

 

So now you use 5700kWh every year.

Someone without an EV uses 3700kWh.

When all cars are EVs then every household will be using an extra 2000kWh.

 

That`s what I get from your figures.(yes not every household the same etc but you get the gist).

There is apparently 200000 EVs registered in Germany at the moment.Once every car is an EV then that will be 43m more people using an extra 2000kWh

That has to come from somewhere ?

First, part of it comes for free. There is overproduction of electricity during the night. You cannot turn off gas, coal, nuclear plants. You also cannot use wind energy. My rough guess is that you could have 30% of the energy "for free", meaning it is normally wasted (although the energy suppliers would charge for it!). The 43M cars will not be replaced overnight. My opinion is that part of the production will come from local solar panels, like supermarkets, houses, companies, etc. The rest can be slowly scaled up over the years, as ICE are replaced by EVs.

 

Second, the power grid is scaled for peak hours. Meaning around 20h00. Night charging would probably not reach that peak, so almost no scaling (or none) is required on the grid.

I think it will take until 2050 to replace all those ICEs if not further.   So I am confident we can source the electricity somehow.
