Hah interesting: electric cars are significantly cheaper in Denmark and Sweden (for once), and it's likely mostly due to a much larger market share and more competitive market, although Sweden has a bigger market overall.

Waymo is now blocking the only eastbound through lane on Townsend, a key SF arterial. AVs have a scaling problem in cities. This isn't just inconvenience but a loss of network capacity. Waymo cuts SF's ability to move people and goods in its streets. User convenience ≠ system efficiency

Country that invented social media has low social cohesion. 🤔

Yes. Actually I heard that interview just before I heard the Volts-podcast - quite a coincidence.

Regarding the questions whether data centres may be denied grid access (or worse, displace industrial electrification): The Danish national TSO has a 63GW backlog of connection requests (vs a current total 7GW demand) and is now asking the government for permission to say no to more data centres.

That’s almost exactly the same as the current EU ETS price.

This is such great reporting.

I really wonder if the slipshod approach we see from the chemicals sector is indicative of other fast and loose approaches to honest dialogue.

Indeed. Interest organisations work to advance their members’ interests. And the members who can afford to pay are typically the incumbents.
But in this case it seems the interest organisation is more pushing its own interests 🤔

Big EU lobby groups exaggerated industry support for attack on carbon price A letter to EU leaders was issued ‘on behalf of’ 1,300 signatories. Some firms deny they supported the demands.

An influential industry petition criticizing the European Union’s core climate policy implied its demands were supported by some 1,350 companies and associations.

Now some firms deny they signed up.

There is a clear trend that emerges. Countries first tap into the solar market, then a year later they seek to deploy batteries.

Europe did that after the gas crisis caused by Russia's attack on Ukraine. www.bloomberg.com/news/article...

FT: "The EU's climate retreat problem: punishing early movers"

Policy Pendulum

Policy Pendulum

One real problem with rewarding the laggards: punishing those who took policy pronouncements seriously.

Regulatory uncertainty—and the resulting cost—is a core feature of Trumpian chaos.

It might be more pernicious in the EU that prides itself in rational policy-making.

Excellent framework for analysing and addressing transport poverty, as laid out at today’s conference on EU’s Social Climate Fund, in a brilliant presentation by @giuliomattioli.bsky.social.

Also several other insightful talks and panel discussions. All in all a great day on an important issue.

Det mener jeg faktisk at DR skrev at hun sagde, ja.

Men begge parter skal selvfølgelig have ret til at demonstrere, *under samme regler*, og ideelt set med samme mediedækning.

Tak. Havde godt fulgt ring 5, men vidste ikke det med Als-Fyn (om end forudsigeligt).

This is why I write so much about pavement parking

Great answer! 👌🏻 Hope you don’t mind I use it too. (Now I almost can’t wait until I get the chance)

Lol, just heard from a German friend who is calling the backup in the Straight of Hormuz right now the "fossil fuel dunkelflaute."

Niche humor.

Ammoniakken fra den grønne brint bør i første omgang erstatte den sorte ammoniak der i dag produceres fra fossil gas.
Luftfartens klimaneutralitet opnås ved at flyve videre på fossilt brændstof og så stoppe det indfangede CO2 i jorden (i stedet for at raffinere det til e-kerosen), jf figuren.

Og dog. Der er faktisk noget bedre, både klima- og prismæssigt: Brug den indfangede CO2 og grønne brint hver for sig, og få mindst dobbelt klimaeffekt til samme pris, jf figuren 👇🏻

Det er rigtigt at der er en vis (begrænset) mængde reelt* bæredygtig biobrændstof. Den er dog nok bedst brugt i søfarten, da man så kan spare energi og kr på at raffinere. Skibsmotorer er mindre kræsne end flymotorer.

Der er allerede sat penge af til banens elektrificering. Men måske til klimasikring - her mangler der penge.

Det som banen (og vi som gerne vil tale pænt om banen) har mest brug for lige nu er dog at man faktisk leverer.

The French “made-in-Europe” EV bonus, which has also been embraced by the European Commission, means that Renault will start producing the battery for the R5 in Europe from April. This will result in an additional bonus of €1,500–2,000 for buyers.

Det er alt for mange penge at betale for at nogen kan flyve til Aalborg med marginalt bedre klimasamvittighed. Og så endda på en måde der ikke skalerer.

Havde været bedre fx at bruge dem på hurtigere lastbilomstilling. Eller på at joine Norges projekter om elfly.
