On sale: Chinese solar PV panels. "[...] they still sell for below their average production costs." Should we buy them while offers last?

Now just imagine how many people see others cycling for transportation but are part of the massive "cautious but curious" crowd, waiting for safer, more enabling infrastructure design.

Our latest @bruegel.org: How Europe should respond to the Iran gas shock – and how it shouldn’t tl;dr The EU should prepare for persistently higher gas prices and use this crisis to advance long-term decoupling from fossil fuels by pushing electrification 🔗: doi.org/10.64153/JZB... 1/5

Great 🤦‍♂️ We are in an energy crisis, and EU countries decide to spend a lot of money boosting energy demand -- thus making the crisis worse -- and subsidising wealthy households, at taxpayer expense! Should've rather targeted assistance, as e.g. income support, to those households who need it.

Der heutige Artikel des @tagesanzeiger.bsky.social zum Thema Benzinpreisdeckel und Tankrabatte zählt sehr gut auf, wieso diese unsinnig sind. Gleichzeitig diskutiert er auch wieso Politiker trotzdem versucht sind, darauf reinzufallen. www.tagesanzeiger.ch/billiges-ben...

For the first time ever, heat pumps outsold gas boilers in Germany in 2025. 48% of all new heating systems installed last year were heat pumps. Gas fell to just 39%. A decade ago, heat pumps had a 7% market share. The transformation has been remarkable.

Perennial reminder: IKEA sells induction plates for $50. Cap the gas line, put the induction plate on top of the gas stove, and avoid spewing carcinogens into your home. Yes, you can also spend $5k on that beautiful high-end stove, while vying for that Michelin star. www.ft.com/content/14f6...

this is a significant victory in a campaign that has been going on for at least a decade. #econsky #academicsky #medicine #Germany marketdesigner.blogspot.com/2026/03/germ...

This tactic should be recognizable to a LOT of us. But we don’t have to fall for it.

Lie: Bike-lanes cause traffic congestion. Truth: Bike-lanes help solve traffic congestion. Lie: Bike-lanes hurt street shops if they replace parking. Truth: Bike-lanes help street shops more than street parking does. Lie: Bike-lanes cost us too much. Truth: Bike-lanes save us all public money.

Or…ride a bicycle.

The city’s transition away from the car, tho fantastically chaotic, has become a global role model. Under mayor @annehidalgo.bsky.social, Paris was “the most influential city in the world”, says Canadian urbanist Brent Toderian. Hidalgo, stepping down after 12 yrs, exulted: “The bike beat the car.”

#Methanol is a key starting material for chemical products. Researchers from ETH Zurich can now produce this precursor from #CO2 and hydrogen with high efficiency using single atoms for #Catalysts.

Germany's BEV share in car production is (quite a bit) higher than Switzerland's BEV share in car purchases 🙈. And they say the German car manufacturers were dragging their feet...

"A chat room for chat bots" I'm checking the calendar. Is it April 1? "Users have to give the chat bot root access to their computers" I'm throwing away my calendar. It must be April 1!

Kristi Noem, the secretary of homeland security has lied grotesquely. She should be fired

WATCH: If you really STILL don’t understand how car-dependent suburbia is HEAVILY SUBSIDIZED by downtown & all the urban parts of your city, please watch this EXCELLENT video by #NotJustBikes helped by #UrbanThree & @StrongTowns.org.

Ich verurteile den bewaffneten Angriff der USA auf Venezuela. Dieser Angriff stellt eine schwere Verletzung des Gewaltverbots der UNO-Charta dar. Es ist eine Frage unserer Glaubwürdigkeit, dies auch klar zu benennen. Wir müssen die Flagge der internationalen Rechtsstaatlichkeit hochhalten.

Marco Rubio is reportedly saying Maduro will stand trial in US courts. Which means it’s now the US administration’s position that US courts can hold foreign presidents, but not the US president, accountable for crimes.

It's actually important that, to the extent you are able, you stop using oil

The article doesn't just contain statistics on loneliness, but also points to some ideas on what to do about it. More Christmassy, than what I thought :)

The real breakthrough of the year isn’t AI. It’s the explosive growth of renewable energy.

Several thoughts: - I welcome ways to efficiently turn ideas into accessibly written communication. - How do we ensure quality control? It has to be linked to the reputation of the author, right? - It is already hard to keep up with academic literature. With AI, publication cycle may accelerate.

Your thoughts/views on this type of service (highlight is mine)?

Your 40-year-old gas furnace stops working on the coldest day of the year. (Narrator: it always happens on the coldest day of the year.)

Nachtrag 2 zur #Lanz Sendung von gestern. Ein 🧵. Ich will noch mal einen Schritt zurueck machen und das mit der Rente etwas genauer erklaeren, weil es schon wieder diese Beschwerden gab: "Boese neoliberale Oekonomen wollen nur die Rente kuerzen."

@steffischnydrig.bsky.social diskutiert im verlinkten Zeitungsartikel in der Luzerner Zeitung, wie man anhand meiner Studienergebnisse über die Klimaseite der @jusoschweiz.bsky.social-Initiative «Initiative für eine Zukunft» nachdenken kann. www.luzernerzeitung.ch/leben/co-emi...

Academics in Assyria in the 7th c BC complain that admin is preventing them from doing research and teaching

Finland has a goal to be net zero GHG emissions by 2035. Emissions were declining, the LULUCF removals were strong, the plan was looking good, but then LULUCF collapsed. Net GHG emissions have actually risen over the last decade! www.treasuryfinland.fi/investor-rel... 1/

Kimmel will probably quadruple his net worth in Federal Court.

New article: sjes.springeropen.com/articles/10.... @florian-landis.bsky.social examines how different consumption goods contribute to household-level responsibility for global greenhouse gas emissions in Switzerland and explores climate policies that create equitable outcomes. #EconSky

Betting on hydrogen as the key solution for decarbonising industry looks increasingly like a very bad idea. Yes we will need to replace grey and black hydrogen used as feedstock with clean hydrogen but as a fuel the economics look terrible.

When she reached London in 1939, rescued from Germany, she resolved to make hers a life worth saving. She would fritter none of it away. We remember the refugee who made billions in software

An electric utility's email alert program appears to reduce peak demand and provides significant private savings to the utility. Social savings, however, are small, from @GibMetcalf.bsky.social https://www.nber.org/papers/w34089

Publication alert: I look at how consumption based responsibility for global warming is distributed across the Swiss population (others have done that before me). Then, I discuss what the consequences of this for climate policy may be. doi.org/10.1186/s419... #ClimateSky #EnergySky

Eine gute Analyse, warum eine Umsetzung des Energie-Deals zwischen der EU und den USA praktisch unmöglich ist: www.reuters.com/business/ene...

This reiterates the point I’ve made a few times on here: the US’s loss will be other countries’ gain, but overall it will be an enormous loss. There is no other country that can replicate the US research investment or environment, and the primary brain drain will be out of research, not overseas.

Been following the energy sector pretty closely since 2010. Really wouldn’t have believed this back in 2019.

Transfer fees for money sent home by international migrants were nearly as high as US foreign aid in 2023

Modern academic publishing means I don’t have access to the published version of my own paper. 🥲

We need to teach students that LLMs are bullshit -- that is, they have no concept of true or false -- and to critically read every single sentence. My students find this very hard. The human mind equates perfect and confident prose with intellect, intelligence and integrity.

Nein, @srfnews.bsky.social, ich glaube nicht dass man sagen kann, dass China das angefangen hat

Emissions reductions + CCS > only emissions reductions according to current NDCs > only CCS (Also: CO₂ > CO2 > CO₂)

I actually love this because it so succinctly captures the entire MO of this administration and this party — “some people said things that made me feel bad about my beliefs and my actions and my place in this world, so now I’m entitled to cause mass destruction and material suffering”

Every day, we get more evidence that congestion pricing is making car trips faster in Manhattan, making bus travel more reliable, and increasing the use & load factor of our mass transit system. Cannot think of a recent policy that has been so *immediately* successful. www.fox5ny.com/news/has-nyc...
