Private electricity consumption is only a small part of the total electricity consumption. While private consumption might be doubled when switching to electric cars, 20% total increase is a reasonable expectation (in Germany it would be somewhat less than that).

Increase in total capacity is irrelevant when people want to charge their cars _at home_. The circuits for residential areas need to take into account the increase in capacity.
And when private electricity consumption is very small, wtf was with the move to LED lighting for and the ban of incandescent bulbs?

Increased demand for homes can be handled by adding more transformers. The lines are fine, but the number of homes per segment behind a transformer needs to be reduced. This is already ongoing in Germany for example.
And the switch from incandescent to CFL/LED did save a lot of energy in total, both for residential and business applications. I once read the number that the net load was reduced by 1 GW due to the change. That is a reasonably sized nuclear power plant.
Their numbers don't add up. My apartment consumes around 400kWh a month. Assuming I charge a Tesla with 82kWh battery and I use it all in a month, the additional energy consumption is: 82/400 = 20%. And that is only on the fat chance that I will be driving less than I do today.
So prove me wrong.
It's physics. All the energy that the cars consume has to come from somewhere. And people will drive more especially because the car is now somehow 'green'
