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.

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.

After Elsevier cut off the tap for the journal Water Resources and Economics in 2024, the research is flowing again, with the launch of the independent new journal, Journal of Water Economics. Edited by the same team, backed by U. Waterloo. #Econsky πŸ˜ƒ

The good news is that the editorial board continued after Elsevier ditched us; this week we launched the Journal of Water Economics:

Open access, no APC, and no Elsevier.

Decent summary of "... a consideration of the investment of our finite publishing resources on this journal vs other journals in our list."

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 β€œ3=2” on it!

That’s just me though.

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.

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.

Wat zou helpen is beschikbaarheid data over watergebruik door bedrijven. Voor welke processen wordt drinkwater gebruikt? Is grijswater een goed alternatief? Kan drinkwater lokaal meer circulair worden hergebruikt? Etc.

en 4) we gaan wellicht de bovengrens op belasting op leidingwater (BoL) van 300m3 verhogen (effect onzeker want nog nooit onderzocht)

Al met al erg veel onzekerheid en de gevolgen van waterschaarste zijn onduideljik (bouwbeperkingen? aanbod verhogen ten kosten van natuur/landbouw? drukverlaging?)

Antwoord minister:
1) we vergroten productiecapaciteit van drinkwater (dit is erg moeilijk en vereist hoge investeringen)
2) we gaan onderzoek doen (tja)
3) we doen van alles op het gebied van communiceren, stimuleren en reguleren (maar dat werkt dus niet)

Dit is het mooiste plaatje. Vergelijkbaar met figuur 2 in esb.nu/dreigend-dri.... Het was een crime om de data bij elkaar te sprokkelen uit dertig vewin rapportjes.

Uitstekend rapport van de rekenkamer over schaarste drinkwater. Drie knelpunten: 1) onzekere gedragsverandering, lage prijselasticiteit, en te trage technische ingrepen.

Just received my first hallucinated cite, a "hallucite"?

I am pretty sure this paper does not exist:

Farmaceutische industrie begint rechtszaken over kosten waterzuivering De EU heeft een richtlijn aangenomen voor schoner rioolwater. De rekening gaat naar producenten van geneesmiddelen en verzorgingsproducten. Die vinden dat oneerlijk.

Als Shell niet verantwoordelijk is voor COβ‚‚-uitstoot door verbranding van hun olie (Scope 3), hoe kun je dan farmaceuten verantwoordelijk maken voor medicijnresten in het riool?
