Excited to share a new paper I got to help out with! How much emissions do EVs cause through the electricity they consume? How do we know? Our paper shows that frequently used metrics *over*-estimate EV emissions. iopscience.iop.org/article/10.1... by Riti Bhandarkar, Qian Luo, @jessedjenkins.com

Yes, my favourite energy transition stat: Chinese sales of oil-powered cars peaked in **2017**🤯

My lab's been attacked by an anti-wind group and their lawyers. They threatened the science funding of my whole university, to shut me and my undergraduate research assistants up. NYT just covered it. 1/n www.nytimes.com/2025/08/25/c...

Disturbing article about climate change's impact on pregnant women: "The world had been reducing the numbers of mothers dying in childbirth, deaths of newborns and stillbirths, but progress has slowed in the past decade." Tens of thousands of babies killed by heat www.economist.com/internationa...

Some truly amazing news: I've been appointed full Professor of Energy & Climate Policy at @ox.ac.uk. Honestly have to pinch myself. It's been a non-traditional path to academia, and it feels like things have come full circle from starting an enviro group as a kid in the late 1980s.

This graph is from the Environmental Impact Assessment report of a proposed data centre here in Ireland that claims to be "in compliance with" the national climate commitments, despite planning to be powered with on-site generation using gas.

Sicily is so hot that the region has just issued an ordinance to suspend various types of agricultural and construction activities on hot days to avoid accidents at work. Essentially these activities will be off at 12:30-16:00pm until 31/8. But let’s talk again how expensive climate mitigation is..

The #IST25 is on! With over 500 participants from all around the world. Nuno Bento from ISCTE officially kicks off the conference, after Florian Kern announces that @transitionsnetwork.bsky.social is finally on BlueSky!

My second day at #EuSPRI2025 begins with Johan Schot, from @utrechtuniversity.bsky.social, presenting his paper "Exploring thresholds for accelerating sustainable transitions." He argues that acceleration follows changes in rules that govern behaviours and suggests a way to measure them!

Starts the #EuSPRI2025 conference in @tu-dortmund.bsky.social! Prof. @uwe-cantner.bsky.social from FSU Jena delivers the first keynote on "a new role of the state for (transformative) innovation." He discusses degrees of state intervention in innovation, and the endless debate market vs. planning.

IEA World Energy Investment Report: As always, a lot of interesting data & figures. While renewable energy investment increases, fossil energy investment doesn't decline.

Good morning with good news: After adding ~19 GW of small solar in 2024, Pakistan's distributed solar surge continues in 2025. Pakistan now adds 1-3 GW/month of solar! With 2025 battery prices falling ~33%, batteries are often paired with small solar. Great! www.ft.com/content/2b4c... #energysky

Today Zurich 🇨🇭 celebrates the opening of the city tunnel - entirely dedicated to cyclists. Once planned as a motorway through the city centre, the plans have changed for the better, giving way to active mobility (and lots more bike parking at the main station).

FUSION☀️ overtakes FISSION☢️

Energy supply security is key to the clean energy transition, but models sometimes overlook it. Our new paper, in @cp-iscience.bsky.social with @empa-materials.bsky.social colleagues, introduces the ESS Pyramid, a hierarchical framework to assess and strengthen security in future energy systems 🔌💡

It's too early to draw strong lessons from the Iberian blackout but one thing remains clear - getting investments right into Europe's electricity grids is crucial for a sustainable energy transition 👇

España y Portugal sufrieron ayer un apagón masivo. No sabemos todavía qué originó el apagón. Intento explicar lo que sabemos. En la red eléctrica siempre tiene que haber la misma generación eléctrica que demanda. Cuando eso ocurre, la frecuencia de la red está en equilibrio.

Lo que hizo ayer @redelectricare.bsky.social recuperando el suministro tiene una complejidad técnica enorme y es digno de agradecer. Lo que hicieron ayer bomberos, policías, médicos, maestros y todos los que colaboraron para que todo siguiera funcionado también.

Spanish PM: "At 12:33 AM, 15 GW of power generation were suddenly lost. They were lost in barely 5 seconds. This is something that has never happened before. 15 GW are roughly 60% of the demand at that time."

How big was today's blackout in Spain and Portugal? 12:30 AM Gen: 32 GW -Solar: 19 GW -Nuclear: 3 GW -Wind: 3 GW -Hydro: 3 GW Demand: 25 GW 12:35 AM Gen: 14 GW (-18) -Solar: 9 GW (-10) -Nuclear: 0 GW (-3) -Wind: 2 GW (-1) -Hydro: 1 GW (-2) Demand: 25 GW Source: demanda.ree.es/visiona/peni...

➡️ Activados planes de reposición del suministro eléctrico en colaboración con las empresas del sector tras el cero ocurrido en el sistema peninsular. ➡️Empezamos a recuperar tensión por el norte y sur peninsular, clave para atender progresivamente el suministro de electricidad.

EU emissions in 2023 were *lower* than during the 2020 pandemic! Newly released data shows that both CO2 and GHG emissions continued going down in 2023, despite the troubling weakening of emission sinks.

The EU has released its latest GHG emission inventory, with data up to 2023. The good news, GHG emissions continue a downward trend, currently 37% below 1990 levels. The bad news, a significant downward revision of land-use removals (LULUCF). 1/

BREAKING: On Friday, the federal government issued new demands of Harvard University. The university's lawyers just responded: back off.

After 10 years negotiating, and despite a last-minute US exit, countries at the UN International Maritime Organization strike a deal to cut shipping emissions Although imperfect, let's celebrate an agreement to tackle the emissions of an entire sector at a global scale! www.bbc.com/news/article...

New piece from me published in Nature Climate Change: Decarbonization can improve energy security, robust trade and a circular economy increases energy security, and critical minerals are not like oil. 🔌💡 Journal link: www.nature.com/articles/s41... Open access link: rdcu.be/eg3lR

If tariffs stay high, where will the $12.7 billion of Chinese batteries go? It sounds like an opportunity for others to leapfrog their clean energy deployment (if their economies hold on)! Lots of trade data in @harvard.edu's Atlas of Economic Complexity: atlas.hks.harvard.edu

Worldwide rooftop #solar could knock off 0.05-0.13 degrees Celsius before 2050 Large shares of available rooftop area in China, India, and Indonesia, where grid electricity is dirtier, make rooftop PV's mitigation potential significant. Claims new paper in @natclimchange.bsky.social: rdcu.be/egPvB

Those trying to understand the tariffs as economic policy are dangerously naive. No, the tariffs are a tool to collapse our democracy. A means to compel loyalty from every business that will need to petition Trump for relief. 1/ A 🧵 to explain his plan and how we fight back.

Welcome to debt brake d-day. Germany is quick to adjust to the new global order and is doing so in force. @davideoneglia.bsky.social shows the package outstrips the spending booms that came with the postwar Marshall Plan and with German Reunification in the early 1990s.

📢 Big Personal News! At the end of April, I’ll be leading the Energy Programme @ecioxford.bsky.social @ox.ac.uk @oxfordgeography.bsky.social. I’m excited to build on its legacy of world-leading energy research and create a global powerhouse on energy demand. 👇 www.eci.ox.ac.uk/news/global-...

"It's the lack of innovation that threatens our future, not the goals [for lower CO2 emissions from cars] that were set eight years ago." Well said!

A happy ending to the negotiation thriller of the past days: €100bn of the €500bn infrastructure package will go to climate spending and the legal text will include language on additionality. Balanced outcome—and a big win for both Germany and Europe.

La amenaza del cambio climático al turismo en Europa España, como región enfocada al turismo de playa, podrían perder del 1% al 18% de visitas en verano, sin que un aumento en invierno llegue a compensarlo Interesante paper del EU-JCR: iopscience.iop.org/article/10.1...

OUT TODAY: How is the US electricity transition doing? WIND+SOLAR OVER TOOK COAL: Wind and solar now at 17% of US electricity supply; coal falls to a record low of 15%. Only 6 years ago in 2018, coal generation was x3 that of wind and solar🤯

In Nature Climate Change, @chrisbataille.bsky.social and I describe three common situations when energy/economic models are detrimental to climate policymaking efforts 🧵 rdcu.be/ecSMX
