THIS WEEK THE ELECTRIC VEHICLE BECAME THE ENDGAME
Something really important happened this week: the German carmakers agreed that for the coming ten years, they will put all their cards on electric vehicles and they will not be shy about saying so anymore.
handelsblatt.com/unternehmen/in…
I think the rise of the electric vehicle (EV) was inevitable once it became clear that you could construct lightweight batteries that would outlast the car, while battery cost plus electricity would be much less than the cost of gasoline.

It's basically that simple.
Of course the success story behind that is the electric motor. It's basically the only alternative for the combustion engine that we know of and it's around four times more efficient. Oh and lighter, smaller, cheaper while not requiring maintenance.
Still, I've not been shy in saying history shows that market leaders seldom embrace the technology that will put their current cash-cows out of business. They usually go bankrupt. That's why @Tesla and @elonmusk where so important: they showed it could be done and sped things up.
But Tesla only produces few vehicles. We need the big boys on board. That's why it's so important that Ghosn showed leadership at Nissan and Renault. And that's why it's so important that China is now going all-out on EVs. But VW is still the biggest car maker in the world.
I was truly worried that the EU car market would pass up the opportunity to reshape itself. I now think #dieselgate hit Volkswagen so hard that it served as a rude but timely wake-up call. (beautifully captured by @Gardiner_Beth theguardian.com/environment/20…)
Which brings us to this week. On monday we learned that Diess, the CEO of @VWGroup "created division in the car industry" with his focus on EVs and charging infrastructure. He was "evaporating billions". Most German writers I read where horrified.
handelsblatt.com/unternehmen/in…
We learned it was actually "worse": Diess threatened Volkswagen would leave the powerful German car lobby VDA because VDA would not commit to an electric-vehicle-first strategy. VDA claimed there where many roads to Rome and the EV was just one.

This lead to heated talks with @BMW chef Harald Krueger. Krueger made very clear that BMW did not agree with Volkswagen faz.net/aktuell/wirtsc…
and it was interpreted as a collision course
welt.de/wirtschaft/art… or even "earthquake" (faz.net/aktuell/wirtsc…)
But one day later the row was over. Diess reiterated that not choosing a technology ("technologieoffenheit") was the wrong message (businessinsider.de/vw-daimler-und…) and after a crisis phonecall on wednesday (handelsblatt.com/unternehmen/in…) they agreed:
The German car makers will say clearly that in the coming ten years, the electric vehicle should be the leading technology ("leittechnology"). And in a linkedin post Diess was crystal clear (ht @colinmckerrache) linkedin.com/pulse/leittech…
This, ladies and gentlemen is history in the making.

I think future history books will say this was when it became clear that age of the combustion engine was over and the age of the electric car truly began.

And for me it's the biggest told-you-so-moment of the last 10 years!
And for people making this @elonmusk/@Tesla vs @VWGroup: Elon liked this thread praising VW and Diess because he knows this is not about carmaker vs carmaker but about EVs vs big oil, about 'trying to be useful' and about leaving this planet in good shape for our children.

The official report on the blackout in Spain and Portugal is just released. I'll give a quick summary of findings and provide some additional info.

TL;DR
conventional power plants didn't control the voltage as planned
over-voltage caused renewables to turn off as required
The report (of which only press reports are available) points the finger to

1 conventional backup plant taken offline for maintenance without replacement being arranged

9 other conventional backup plants, of which every one had a degree of non-compliance
uk.news.yahoo.com/spain-reveals-…
Renewables also had a role: "tension was very high and sustained, causing the disconnection of generators".


An inside source tells me the voltage went above 110% in many places and solar was required to switch off, which meant 8GW was lost all at once.elpais.com/economia/2025-…

Just made a visualization for myself about the unprecedented growth in solar that I thought I might share.

From 1880 to 1950 all electricity came from fossil+hydro. Then nuclear briefly grew with market share increasing with up to 1% per year in 1985.

Now solar takes over. Image
I've described in more detail in a substack post:

There's more info on each picture there.aukehoekstra.substack.com/p/the-coming-s…
I made this picture because I think you forget what is happening when you look at total final energy. Renewables seem so tiny! Image

I see this a lot:

Conservatives who *just know* that nuclear is better than solar and thus blame their favorite scapegoat *the government* for solar doing better.

But in reality it's the opposite: the market likes solar so much that not even the government can save nuclear.
I guess Andre's attention for me is due to my being irritated at his fact free diatribes of pseudo-scientific nonsense:


So now he sees reacting to me as a way to get attention?
And I'm reacting again, so maybe I'm being duped?
Anyhow...
Let's start with some quantifiable facts. (Things this conservative armchair energy philosopher is allergic to.)
First thing we notice is that solar and wind are clearly surpassing nuclear (though the new leadership of the department of energy denies it).

Many people think solar and wind won't be able to keep the grid stable because they lack "inertia".

I think solar, wind and batteries will do a BETTER job and I think you can explain it thus:
- the old grid is a record player
- the new grid a digital player
🧵 Image
If you play vinyl records, the rotating mass of the turntable is used to keep the speed steady. This leads some vinyl enthusiasts to seek more mass because that will keep things more steady.

This turntable by Excel audio attaches a separate mass. (Overkill but makes my point.) Image
In the same way the inertia in the rotors of current power plants helps the grid to keep a steady 50 Hz (in e.g. Europe) or 60 Hz (in e.g. the US) frequency.

These machines turn a heavy copper coil wound around a heavy iron core and this helps keep the grid frequency steady. Image

Great to see more and more attention for flexible grid pricing.

We must say goodbye to the "copper plate" that offers free power everywhere and every time. It's hideously expensive and outdated.

What we need is smart flexibility.
🧵
The underlying reason is that the costs of different components of the energy system changed:

Some remained high (e.g. pylons, fossil & nuclear)

Some plummeted (e.g. solar, wind, batteries, EVs & inverters)

Some became possible at all (e.g. measuring & steering in real time)
So now we should make good use of these new, clean, abundant and affordable options, even if it means doing things a bit differently than before.

So what should we do different regarding grid congestion pricing?

Some are angry about the "anti-Christian depiction of the last supper" at the Olympic Opening ceremony. (@elonmusk and @realDonaldTrump among others)

A Dutch art historian explains it's not the last supper but a Dutch painting of the Olympic gods.
And I explain what I loved.

Original Dutch thread here. I just translated it.


@WSchoonenberg shows that the "tableau vivant" (living painting) is depicting "The Feast of the Gods" by Jan van Bijlert, from 1635.
Image
The heathen Gods have gathered on mount Olympus for a feast. Sun god Apollo is recognizable by his halo, Bacchus (Dionysus) by the grapes, Neptune (Poseidon) by his trident, Diana (Artemis) by the moon, Venus (Aphrodite) by Cupid.
