People think that the share of immigrants in their country is higher than it actually is. In most countries, the overestimation is more than 10 percentage points.

In 2024, China🇨🇳's total renewable generation grew TWICE as much as it every had done before.

It added 494TWh - that's the total electricity demand of Germany🤯

"no one has died" because of feeding USAID to the woodchipper, Elon claimed. In this devastating piece the NYT went out and learned some of their names and stories:

Paleo artists often "shrink wrap" fossilized animal depictions

The T-Rex, Utahraptor, Triceratops—popular depictions of each of these animals shows skin so close to bone that it might be unrealistic

So let's shrink-wrap existing animals🧵

Can you guess what this is?

🚨2023 is now "virtually certain" (>99%) to be the HOTTEST year ever recorded🚨

It's set to smash the previous 2016 record by ~0.12C

Every single one of the last 10 years is among the hottest 10 years on record

What can you even say about this?

🥷 Introducing https://t.co/ahvPap3kq6 – a new tool to model hourly energy demand in individual buildings to entire countries 🌍

Our new @NatureEnergyJnl paper shows how to model electricity & gas demand with precision, and what we learn from this …

Air pollution reduces global life expectancy more than tobacco smoke or malnutrition

Global life expectancy reduction due to
Air pollution: 2.3 years
Tobacco smoke: 2.2 years
Malnutrition: 1.6 years

These two objectives are impossible to reconcile:

1) “housing needs to get dramatically cheaper, so that new generations and working class people can afford it.”

2) “housing needs to keep getting more valuable, so that older/longtime residents can build wealth/fund retirement.”

Weekend reminder that SimCity's creators couldn't accurately reflect the scale of urban parking lots because if they did the game fell apart.

Massively under-appreciated point:

Shifting from gas boilers to electric heat pumps would cut heating gas demand by two-fifths, even when running on 100% gas power, because burning fossil fuels is wasteful and heat pumps are magic*

Allow me to explain…

We conclude with a research roadmap and suggest:
1. Modeling electric vehicles flexibly
2. Identifying and modling explicit loads for DSM
3. Modeling storage with more constraints
4. Introducing actor heterogeneity
5. Reporting a broader range of metrics
4/4

[Febin @FebinKach]

Quick thread to mark the publication of my first (!) PhD paper. We reviewed how flexibility is modeled and robust results are ensured in energy system models, concluding with a research roadmap that is hopefully useful for fellow modelers. 1/4

Like @akrumm_ et al., we found that social aspects such as heterogeneity and acceptance are undercovered and often exogenous. Most studies also report little beyond cost and emissions, which limits their value to decision-making. https://t.co/85ZZ7LwbTl 3/4

Es ist ein demokratiepolitisches Experiment, das wir sehr ernst nehmen sollen: Der österreichische Klimarat hat seine Ergebnisse präsentiert. Und sie zeigen, dass wir Klima und Demokratie anders anpacken müssen. Ein Thread.

To great uncertainty and controversy, in 2007, Ljubljana closed 12 hectares of its city center to private cars. Just 40% of residents approved.

A decade later, no less than 97% were against reopening to motor traffic: “None of us can really imagine cars ever staging a comeback”.
