Your source goofed their statistics.

Globally, only 36.7% of our electricity was low-carbon in 2019. However, some countries get over 90% of their electricity from nuclear or renewables [mostly from hydropower and/or nuclear energy] – Sweden, Norway, France, Paraguay, Iceland, and Nepal, among others.
In the years to come, accelerating the transition to clean electricity will become ever-more important, as we electrify other parts of the energy system too (shifting to electric vehicles, for example). We will need to rely on low-carbon electricity, and lots of it.
I'm confident [95%] we will do so.

So over 56% of worldwide electricity production came from coal and gas (33.79% coal and 22.79%).
You mention a few small population centres having 90% of electricity from renewables or nuclear... they are but a blip on the population curve.
The elephants in the room are India and China, representing 36% of the worlds population.
Both of these countries are RAPIDLY expanding the building of coal fired power stations. VERY rapidly.
I would not be surprised if those 2 countries expand coal fired electricity production FASTER than the entire rest of the world expands renewables and nuclear.
In my opinion there is only one way to meet renewable goals long term, and that is with Nuclear.

European wholesale gas prices have risen dramatically and since this gas is used to generate electricity that price has also risen. A lack of wind hasn't helped and some countries are in trouble particularly those with heavy industry using gas for heat.

Re: Electric propulsion in the future
Indeed. The price of many energy commodities seems to be fairly volatile.
EU Natural Gas ~ Trading Economics
EU natural gas prices retreated for a second session in a row to €156 per megawatt-hour on Thursday, erasing more than 13% since reaching a record high of €180.27 on Tuesday, amid reports of higher volumes being shipped from the US headed to Europe and updates regarding gas flows in the Yamal-Europe pipeline...

Admit it... not only "volatile" but GOING UP... period.

Re: Electric propulsion in the future
The $ price of energy is controlled by 3 metrics...
1)... rate of consumption.
2)... rate of production.
3)... rate of inflation.
#2 cannot match inflation of the $ which is "Officially 6.8%" ... however real inflation is about 14%.
You tell me, how is production EVER going to match inflation, let alone the increasing rate of consumption?
Not gonna happen in my lifetime.

Re: Electric propulsion in the future
What the "Powers That Be" will do to hide the facts is that they will make the cost of energy a smaller and smaller component of the "CPI" over time, to hide from the middle class (the taxpayers) what is really happening.

Re: Electric propulsion in the future
Natural gas is the first in the US on electricity production with about 40.5% and coal is 19.3%. But nuclear and renewables are both just slightly ahead of coal. Coal production has dropped steadily from 896K tons in 2015 to 535K by 2020.

According to the previously cited, Trading Economics website:
Natural gas: is DOWN approximately -2.39% on the day, & DOWN -24.07% on the month, but UP +54.21% on the year.
➥ https://tradingeconomics.com/commodity/eu-natural-gas
So, I’d repeat that Euro gas prices are volatile, with an admittedly generally upward trend.

Re: Electric propulsion in the future
Stellantis Opens 0.6-Mile Test Highway That Recharges EVs Wirelessly
Similar to wireless smartphone charging, Stellantis plans to use inductive charging technology to power both parked and in-motion electric vehicles.
By installing the company’s Dynamic Wireless Power Transfer (DWPT) tech under the roadway, the system wirelessly charges all-electric vehicles, with Stellantis’ special receiver.
The project now moves into Phase 3, where the firm will test the charging system, at a closed-circuit, built near Italy’s A35 autostrada.
Labeled the Arena del Futuro (Arena of the Future), the project consists of a 1,050-meter (0.65-mile) track, powered with a 1-Megawatt DWPT system.
In the trial phase, a Fiat 500 Electric and an Iveco E-Way Bus will test the roadway's dynamic inductive charging capabilities.
While stationary wireless charging is a step in the right direction, powering cars on the move would be a giant leap for the EV industry.
To provide the utmost safety, the Arena del Futuro also features 5G connectivity, and IoT (Internet of Things) technology, to ensure optimal communication between the vehicles and roadways.
“Arena del Futuro”, Innovative Dynamic Induction Charging Becomes a Reality
Using DWPT (Dynamic Wireless Power Transfer), electric vehicles can be charged “wirelessly”, by driving them in wired lanes with an innovative system of turns installed under the tarmac
DWPT is one of the main technologies made to respond in an immediate and tangible way to the requirements for decarbonization and environmental sustainability in the mobility sector

Re: Electric propulsion in the future
Hmm
Light bulbs don’t power cars - while I totally agree with turning off at least 50% of the lights, to think that’s even a scratch on the surface is misguided.
We are soo short of energy it’s ridiculous, plus how do you decarbonise a building? Well I can tell you, you put electric everything and then buy in low carbon energy, and the problem is gone! Well ok you might say but how does that help? Well it doesn’t matter because it’s no longer your problem! Does this sound harsh? Well this is not my personal view, this is actually the truth of how decarbonisation works! It’s written in law of building design standards of the future, maybe not in every country, but this is the lie / trick that’s coming to a city near you!
Plus houses are generally designed or have been in the past at 2kW each so not enough to power your car, and the charger cable won’t reach your boat 😂
We have a very long and risky way forward

Stop population growth. Otherwise it’s a losing battle no matter what you do!

Very accurate statement and one that should begin the conversation on saving our planet.

Nailed it
Stop population Growth or maybe even create a virus?
