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.

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.

With new batteries solar and wind are not only faster and cleaner, but also cheaper.

I'm estimating:
$0.08/kWh for PV+batteries
$0.07/kWh for wind+batteries

@skorusARK gives a good overview of current wisdom, but strongly declining battery prices change EVERYTHING
Image
I've recently written about how I was surprised I missed the enormous consequences of price reductions in batteries.

LFP cells are now $50/kWh and last 10 000 cycles.
That's $0.005 per kWh.

Say we double that to pack the cells and you are at $0.01/kWh.aukehoekstra.substack.com/p/batteries-ho…
If you add batteries to solar PV, not all energy has to flow through batteries. But let's keep it at $0.01 and add that to the price of solar. That makes PV (and wind) SUPER cheap!

Batteries must be discounted more quickly you say?

Cheap stationary batteries will pave the way for wind and solar in cheap and resilient energy grids. Unfortunately the @IEA is mispredicting it (again).

Thread based on a free substack article I just wrote.

Many of my followers know this picture: it visualizes how the IEA underestimates solar. Now I see basically the same problem in their new battery report.

Image
The IEAs new battery report gives a lot of great info on batteries but also two predictions taken from their authoritative world energy outlook:
1) STEPS which is basically business as usual
2) NZE (Net Zero Emissions) which is aspirational

Batteries: how cheap can they get?

I used the Sunday afternoot to describe how I think that dirt cheap batteries will completely transform our electricity grid, paving the way for solar and wind and replacing grid reinforcements with grid buffers
aukehoekstra.substack.com/p/batteries-ho…
This is something I'm working on for different government and grid operator projects, but I never realized just how cheap sodium batteries could become and how much of a game changer that will be.

So I used my Sunday evening to write this and would love your feedback!
First I look at the learning curve and then we see it is extremely predictable: every doubling of production has reduced prices by around 25%.

It's even steeper and more predictable than solar panels, the poster child of this type of learning curve.

Aaaand we have another winner of the "EVs and renewables can never happen because of material scarcety" sweepstake. I thought @pwrhungry was more serious. Let me explain why this is misleading bollox.
First of all, notice how his argument is mainly that Vaclav Smil says this and HE is an authority.

Why bother to write a substack that basically parrots someone else?

Because you don't really understand it yourself and needed to write another substack maybe?
I'm a bit tired of this because Bryce abuses Smil the same way most people who are against renewables abuse him. They emphasize this is a serious and revered figure that knows numbers. They make it about the messenger, not the argument.

I wholeheartedly agree with @MazzucatoM that we should better evaluate tech companies contributions.

But the focus on energy use makes a mountain out of a molehill while we have bigger fish to fry.

I see computing as both a huge opportunity and an existential threat.
🧵
For me the focus on *how much electricity* an industry uses usually indicates an outdated focus.

We have to get rid of fossil fuels and the mantra is "electrify everything". Because electricity is the form of energy that is usually more efficient and that is greening rapidly.
Many people still can't wrap their heads around the fact that electricity from wind and solar is getting clean, abundant and relatively cheap while we have more than enough materials to make it happen.

IF you focus on datacenter electricity use...
focus on how green it is.
