The common cars owned by a lot of people are likes of hybrid like chevy volt. It has a 18.2 kWH battery. It has a range of 53 miles on pure electric charge which I assume will give 50 KM on charge in non favourable real world conditions (One year on, my real-world experience with a plug-in hybrid electric vehicle | The Guardian). Its charger is a 120 V 15 Amp charger and can charge the vehicle in about 10-12 hours. Thats a lot less power than my electric cooking range. For a city car it will work more than adequate. Need to go from burb to your work place and back? It can do more than fine. That use case is for a hell lot of folks for a hell lot of time. Or take Nissan leaf (Nissan Leaf - Wikipedia). It has a 3.6 kW charger.
Fascinating but it may not be the total consumption that's the problem. However I will nitpick. 10-20kWh per 100km. You wouldn't get 10kWh per 100km even if you drove at a constant 100kph on flat and level ground everywhere, you can work this out from the fact it takes about 70hp or 52kW to achieve 100mph. Uphill, accelerating, etc. and I think it will be several times that, especially given that EVs aren't exactly lightweight. You also have round trip efficiency to consider for charging and discharging, so the lower limit of 10kWh/100km is nothing short of a joke. The average mileage estimate also looks low. 20,000km seem better.Could electric vehicles pose a threat to our power systems?
The electrification of road transport could place new stresses and strains on our power networks. We have modelled various scenarios; here are the results.
In the US it's not a problem, but what about in smaller countries with less space, like the UK?
Even hybrid sales are supposed to be banned in the EU from 2030 onwards, no ICE at all.
In UK / EU, they need to invest in Nuclear power. France is already on top of it.
Yes, for Chevvy Volt, majority of people who used it as a city car only kept the hybrid part just to calm the range anxiety. Chevvy Bolt EV which replaces this model can actually provide more range, but has a larger battery. Still for the same day to day drive, charging at home is not more power intensive than say running heating during winters (mine adds 3-5 KW during coldest parts of winter easily). With heat pumps replacing baseboard heating all over the place, many countries (like Canada) will have lesser load on the grid and that headroom can accomodate these cars.
Unlikely to really, it takes a certain amount of power just to achieve a given speed. Cars already have very low Cds and EVs are heavy so rolling resistance is high. Crash safety requirements and tech. also keep making cars heavier.

I agree but unfortunately too many people watched the Chernobyl mini-series and now think that a reactor can cause a "2-4MT" nuclear blast. We are replacing existing nuclear power stations but adding more is too politically hot. Hopefully fusion power will change that.

In very small amount and largely trial capacity. Look at test figures from magazines for kWh/100km not brochures. 20.3kWh/100km (AMuS test) for a Model 3 is about right yes. So it's over the top end of their estimate.
All you need is a bunch of solutions that your reference study suggests to be implemented nationwide, which would take forever and the scheduling, so as not to disrupt the economy would be a nightmare. This is a 30 year project minimum, probably more like 50.

If you want to ruin the remaining countryside. Better to wait for fusion power, distributed gen brings its own problems to the grid.

I kid you not, but I also thought same about Mercedes A series. These cars are way too silent! May be in coming years there will be regulations on certain level of noise OR automated horns for humans. I mean due to auto driver stuff they are building into these cars, it can now automatically detect humans on the road around them. May be some genius will figure out how to look it up to the car horn.
Well, when Fukushima Dai Ichii nuclear reactor blew up due to steam explosion, there were shrills crying "Cancer Epidemic! Cancer Epidemic!" all over the place. There has been a lot of mess since then (radioactive water leaking into pacific ocean) BUT that cancer epidemic failed to materialize.
Fusion power isn't happening.
ITER, I understand, will yield a stable, net output. The plasma is contained in a magnetic field, which is enough heat to continue the reaction.
The 20.3kWh/100km refers to the consumption per 100km in relation to your linked reference, which quotes as low as 10kWh/100km.

I am around from time to time. The Iran-China deal is something that I expected to happen much sooner, as it was an inevitable outcome of the US walking out of the JCPA. In fact the timing makes me believe that China was just biding its time, waiting for the Iranian fruit to ripen fully before plucking it, and they're acting now out of fear that Biden could undo Trump's action and restore a working nuclear deal. It is in China's long-term interests to keep as many countries as possible fully out of the western sphere of influence, and there's no better way to achieve that than by making sure the west itself cuts all ties and exchanges with these countries. Iran, in particular, is an especially interesting country for China due to its strategic position and energy reserves. I also expect in the coming years, Iran's regional proxies (Hamas, Houthis, etc.) will increasingly become China's regional proxies.
