Er zijn nadelen verbonden aan bloktarieven (huurders, meerdere gebruikers op een meter, ondoorzichtigheid), maar experimenteren kan geen kwaad.

The figure in this paper is fascinating. It's the opposite of the famous image of how renewables growth was always under-estimated in energy projections.

I coded up an open-source, not-for-profit AI paper reviewer that rivals the performance of @reviewer3com.bsky.social, Refine.ink, and Stanford Agentic Reviewer (according to Gemini 3.1). Costs <$2! Live @ coarse.ink. Plug in paper, @openrouter.bsky.social key, and email. #econsky

If you haven't yet changed how you teach and evaluate thanks to AI, you probably need to. This is not something that educators asked to happen, but it is worth noting what is out there - in this case an OpenClaw tool designed to cheat.

I am looking for a PhD student in energy economics starting in the fall, focusing on household-level energy use and energy poverty. More info: jobs.helsinki.fi/job/Helsinki...

On AI & water, it looks like all US data center usage (not just AI) ranges from 628M gallons a day (counting evaporation from dam reservoirs used for hydro-power) to 200-275M with power but not dam evaporation, to 50M for cooling datacenters alone. So not nothing, but also a lot less than golf.

If I was a tutoring company and I wanted to convince you that I could teach your kids maths, I would probably not have an advert that said “3=2” on it! That’s just me though.

This is a problem.

I messed up on my teaspoon conversion, it is 9 teaspoons of water for a query (OpenAI reported 1/15 of a teaspoon). So equivalent to 0.001875% of a hamburger.

'Forever chemicals' are seeping into waterways across Europe. A vanishingly small, man-made molecule resists all attempts of removal. How will the EU eradicate the pollution? www.ft.com/content/a36c...

This Chatham House report notes the Indus supplies 80% of Pakistan's irrigated agriculture -- a system already under grave threat due to climate change. Last year, a severe drought hurt several crops in the country's breadbasket, while Pakistanis were still recovering from previous flooding.

A new working paper with Daniel Banki, @urisohn.bsky.social and Robert Walatka, just submitted to SSRN. The paper is comment on Ryan Oprea's recent AER paper. The paper is processing, but you, my friends, get early entry. papers.ssrn.com/sol3/papers....

Just think, this could have all been avoided if he had just done a PhD in Sweden

Where did that dam water go? Trump celebrated dumping billions of gallons from two dams in Tulare County, saying it was headed to farmers and Los Angeles. But that's not where it went. @ianjames.bsky.social reported on where it ended up. www.latimes.com/environment/...

I've been meaning to read this paper on mass extinctions (pubs.aeaweb.org/doi/pdfplus/...), and today, I came across this great write-up about it in VoxDev (voxdev.org/topic/energy...). It's a great paper. I am glad I found the time to read it. Below is a short thread.

When I was a young man there were whispered rumors among the elders that they could remember their own elders talking about a time when getting grants had been a means for doing science, rather than vice versa.

Prima analyse van @bosdaan.bsky.social en Wouter Ubink: het gaat over de schaarse ruimte in Nederland, waardoor echte langetermijn keuzes steeds sneuvelen in debatten die de politiek vooral langs lijnen van economie en identiteit wil voeren

Vanaf vandaag kan een doctorsgraad worden ingetrokken, vanwege schending van wetenschappelijke integriteit.

Secured a research grant—only to spot a typo in the project title now.

Als gevolg van klimaatverandering en milieuvervuiling dreigen er in Nederland drinkwatertekorten te ontstaan. Beleid dat inzet op waterbesparing via technische aanpassingen lijkt wel kansrijk, schrijven Ansink en Bremer. https://esb.nu/dreigend-drinkwatertekort-noopt-tot-vraagreductie/

Accounting is boring, but this seems important.

For the Dutch-speaking: Here is a piece I wrote on the claimed drinking water shortage in the Netherlands. Together with Leon Bremer I summarize the problem (is it even a problem?) and sketch some possible solutions. esb.nu/dreigend-dri...

Yet another research idea that would not pass the "ethics" criteria when applying for funding

This is an interesting question. Haven't read the papers, only your thread and have some reservations. 1) GDP is a very good proxy for welfare (e.g., explaining 90% of variation in HDI). Testing it causally is always an issue, but near certain causal claim in poor countries. -->

The Economist covered our "Strain on scientific publishing" paper. What is this all about? We collectively churn out more & more papers *per scientist*, an increasing pace, in a rapidly changing publication landscape. Why? How? Want to make sense of this? 🧵 www.economist.com/science-and-...

Yes, I've heard of MIT's Fishbanks, but nothing beats an analog version of a fishing game.

One of my co-teachers just used ChatGPT to provide a summary of one of our student course evaluations. Highly recommended, for two reasons: 1) ChatGPT ignores isolated nasty comments (if any); 2) The overall supportive tone.

What could possibly go wrong...? Tap water in France and Flanders (Belgium) heavily contaminated by TFA (trifluoroacetic acid), a molecule from the PFAS family ("forever chemicals"). While health effects are unclear, some scientists say there's reason for concern, esp. as TFA exposure is widespread.

Since I haven't seen it posted on BlueSky yet: check the report by the "Global Commission on the Economics of Water". I like it quite a bit. economicsofwater.watercommission.org #econsky 1/3

At first glance, Shell's successful appeal against a landmark judgment by a Dutch court looks like a blow to those wishing to advance corporate climate action. But the devil is in the details... via @opinion.bsky.social

I'm often asked what I see as the point of being on social media as an academic (no one ever asks me this but let's go with it). For me, the motivating driver even at the beginning was scale. 1/
