Yeah, you'd have to be desperate to want to get into the UK right now.

If you apply that same methodology to the UK supply, it comes out at 48kW. If we're comparing systems, it's important to use the same methodology as you will no doubt appreciate.

The UK never went away from 240V.
The standard is 230V -6% + 10%.
That covers nominal 220V and the UK 240V without actually changing anything.

Almost none.
The only time ours would trip is if there was a genuine fault condition
- kettle or water heater element going bad or the old filament spotlamps in the kitchen when they blew would generate an impulse plasma short from live to earth that always plunged the house into total darkness. They are all long since replaced by LEDs now and they fail very rarely.
1000L of 28s fuel oil - which is pretty much kerosene. We can also run on solid fuel of either coal or wood in the wood burning stove.Ceramic hobs are fairly responsive. Induction ones even more so.

It is not necessarily anything to to do with saving the planet, although that's a nice side benefit.
Normal charging is more convenient than with a gasoline cars as it is done while I sleep for a few seconds of plugging in when necessary.
Agreed that requires more planning than with a gasoline car but eminently practical.

I think you are mixing up concepts.
That 5 % sounds about right as the running reserve or short startup time (minutes) gas turbines to fulfill the N-1 criterion, i.e. to allow the largest single unit (typically nuclear) dropping from the net. There are time limits (like 30 min) how fast slower starting power plants must be started to restore the N-1 condition. to allow for the next largest unit dropping out.
In any country there are different types of power plants, some are expensive to build but cheap to operate, such as nuclear, other are chap to build but very expensive to operate like natural gas aero derived gas turbines (essentially jet engines). An emergency gas turbine would be run for less than 100 hours including regular test runs.
If you add up the total nominal power output of all available units, this is well larger than the annual peak load. However, running all would be very expensive, so you try to optimize the power station production mix at any time.

OK, but 230 V light bulbs last shorter... Are you saying light bulbs in UK are 240V? Yes LEDs too, see my previous test with those.
No he is right. The available UK generating capacity in winter is now only about 4% more than typical load and last winter but one they had to pay big industrial users to drop off to keep the lights in homes on.

This is from 2014 and it has got worse since then with various operators mothballing unprofitable assets. They got dangerously close to running out of gas in 2018 too - which would have taken a lot of electricity plant offline (a result of the dash for gas a while back).
They are already running the ageing nuclear plants way beyond their predicted lifetime and still dithering about building new ones.
Not in the UK it isn't. Without the demand side industrial load shedding the margin of generating capacity to anticipated winter load in cold weather it is now touch and go as to whether the lights stay on.

I can charge on the street, if I can park within two car spots of my driveway. Apartment dwellers in a crowded city have a problem. Several are like that here at work, but they can charge up in our garage.

LEDs *can* be run directly off 240V in the UK, but their service life will be shorter.

No, I am not.
Scandalously I am right.
No.
All true, but regrettably it doesn't change the fundamental point that we are very near to the limit.
Official "notices of insufficiency" are regularly issued. The audience is those commercial customers that buy cheaper electricity on the basis that supply won't be guaranteed. Summary: such commercial customers should be prepared to be cut off.
The people I have talked to (at IET meetings) whose job it is to keep the lights on explicitly state they know they will not be able to keep them on. The only question is the extent and duration of the cuts.
Since it would be politically unacceptable for peons with a vote to be blacked out, companies and the economy will suffer first.
If smart metering is introduced, with peak-load pricing, people will start finding ways to time their usage. We don't have that here, but I wish we did.

I have that issue, but do my charging for a round trip. What I lose in one direction, I get back on the other.

What are you talking about??? Overnight you can put on 150 miles on most v ehicles. That's a lot more than Win is using and will work for a very larg e proportion of the population.
It's not like there aren't fast DC chargers for trips. Heck, I use 120 V a t 12 amps. I did charge at the hospital parking deck one night at 5 kW to get a full charge and I won't need to charge again until I am back on the r oad tomorrow halfway home. I could go all the way home, but I'm charging on Tesla's dime these days as much as possible.

We already have a vestigial version of that, the so-called "Economy 7" tariffs. They have separate internal wiring to piles of bricks surrounding heating coils (i.e. storage radiators), and only heat the bricks up at night.
Such tariffs and wiring were popular in the 60s and 70s, but have fallen out of favour since then.
As for smart meters, we have them - provided you carefully define "smart".
The government forced their introduction despite being repeatedly told that there were fundamental problems. Consequently, even though some are still being installed, they will all have to be replaced with second generation devices. You couldn't make it up.
Even then, the smarts are limited to: 1 telling consumers their instantaneous and total energy usage 2 remotely disconnecting customers that don't pay the bill 3 staying with the same energy supplier; change supplier and it reverts to being a dumb meter
What could /possibly/ go wrong with the second (mis)feature?
Given the third point, tell me again what the benefit is supposed to be!
Consequently I and many people refuse to have smart meters installed.
