How much of the country will need to be covered in wind turbines?

All of it.

I mean when you run the numbers the whole thing is completely insane.

What is actually happening is that while windmills and solar panels take
the headlines, behind the scenes massive work on SMR nuclear power is
going on ready for the time the public realises 'renewables dont work'

As far as electric cars go, yes 5 minute charge is possible and with a
typical battery in the 60-100kWh bracket that is around 0.72-1.2MW peak
inflow required.

And that poses problems of an engineering sort. But those sorts of flows
are not unusual in a typical electric train... Eurostar draws up to
20MW... so charging 20 cars at a time is no worse than starting up one
high speed train.

Batteries are already equipped with fan cooling.

If you want to think about 'three 3 kw electric fires' instead think
about a 300bhp car that runs at 25% efficiency - so 900bhp of HEAT is
being dumped by that cars radiators. Around 675 kW. It's no big deal to
dump 9kw. And extra fans could be built into the charge points

A bigger problem is the cable that plugs in. And safety. To get currents
down to less than - say 100A - you need 10KV or better. having that sort
of power handled by your typical Europhile ArtStudent„¢ is a frightening
prospect.

But, what it boils down to is a series of expensive engineering
challenges that all have to be solved to make it all work.

I think in time they will be, but I wont hold my breath.

Nor will I expect it all to go smoothly without several serious and
lethal accidents.

Nuclear electric *as far as is practicable* is probably tomorrows world.

BUT to eliminate fossil fuels almost entirely requires about a 3 times
uplift in total grid capacity.

And at least 80GW of nuclear power.

And you don't build that out of wishful thinking
