So to do that with batteries is about 30% more grid needed and motre
generating capacity.

The rest is really heating. That is what would require the greatest grid
increases - all electric heating.


Just a load of bollix.
There are too many unknowns to come to any conclusions at all.

Not at all. Use two sets of assumptions for best case and worst case,
and the final answer will very likely be within that range, probably
towards the worse end.

Some people would charge their cars by night (at an unknown rate.)
Some would charge them from renewable sources.

That would be me not working tomorrow, then. No solar after dark, and
it's a nice calm night. The bus won't be running either, unless we all
start pedalling it to work and back.

And a whole lot of people won't be driving any more.
Public transport will make a big come back

Most public transport is already more expensive and slower than
travelling by car in the UK, once you've made the initial investment,
and I can't see that changing in the foreseeable future. A bit like PV
power from roofs. For local transport, people will likely go back to
pedal power or walking, as in most places at most times now, walking is
quicker than the bus for journeys of a mile or less.

And more people will work from home.

Which will lead to the communications infrastructure needing massive
upgrading, if it happens.

And shop from home.

Ditto, and as the goods still have to be delivered to the point of use,
more delivery vehicles will be needed, along with their depots and
charging infrastructure, assuming they are electric. Still, on the
bright side, it will increase employment.
