20 yrs ago I found that PV, wind, EVs, batteries and heat pumps were predictably and reliably on route to replace finite, dirty and expensive fossil fuels. Wrights law is the way to predict how fast. Innovation helps a lot more than rationing and more focus should be on that.
For almost two decades, the environmental movement has repeatedly announced the demise of fossil fuels. The headlines have been dramatic, but the results have been less convincing.
As @turkiyecop31 is about to begin, the world remains remarkably indifferent — despite the climate crisis growing ever more urgent — as if saving the planet were merely an optional item on the agenda.
@gerardreid14 and I invite @CampanaleMark , founder of @CarbonBubble. Carbon Tracker is the financial think tank that brought the concepts of unburnable carbon and the carbon bubble into mainstream debate. Its research has helped investors understand the risks of fossil-fuel investments but has also been politically weaponised by the Greens.
A decade ago, the debate centred on stranded assets, carbon budgets and the prospect that fossil-fuel reserves would become economically unviable. Today, our thinking is increasingly aligned with perspectives associated with @ember_energy and @MLiebreich, emphasising technology, economics and the practical realities of the energy transition.
We probably are witnessing a schism between former allies: the “Climate Movement” and “The Clean Energy community”. We believe technology, innovation and economics will do more to accelerate the transition than verbose toothless international accords or poorly designed top-down government policies.
Carbon Tracker deserves credit for making climate risk a serious financial issue. However, forecasts about the timing of peak fossil-fuel demand have proved less reliable. Oil demand rebounded after COVID-19, while geopolitical instability and energy-security concerns have demonstrated the resilience of hydrocarbons.
The question is whether the carbon-focused approach remains relevant or whether it is approaching obsolescence.
Environmental campaigners have advocated carbon taxes for decades, arguing that polluters should pay for emissions and that revenues should fund the transition to cleaner energy. But what if the world already has a de facto carbon tax, imposed not by environmental policy but by geopolitical conflicts? Wars, supply disruptions and decisions by powerful governments can drive up the price of oil and gas, imposing enormous costs on households and businesses.
Russia under Putin, Iran under the Ayatollahs and the United States under Trump illustrate how geopolitical decisions can reshape global energy markets.
Carbon Tracker helped establish stranded-asset risk as a serious capital-markets concern. Its central warning—that some fossil-fuel investments could lose value as the energy system evolves—remains relevant.
But the timing of the transition has proved difficult to predict. Fossil-fuel demand has shown greater resilience than some forecasts anticipated, while geopolitics, affordability and energy security have complicated the path towards decarbonisation.
The distinction is important: identifying investments at risk is not the same as predicting the imminent collapse of fossil-fuel demand.
Our conversation was robust, with both sides standing their ground. We left with a sense that the debate needs to move beyond political targets and increasingly outdated assumptions towards the realities of technology, economics and capital allocation.
We may agree on the destination, but the real argument is about the pathway.

“We don’t need to replace waste,” as I told @FT.
Electrifying doesn’t just change the fuel, it shrinks the amount of energy you need.
Our forthcoming paper finds the same useful energy with roughly half the primary energy.
I call it Electrofficiency.

El MIT ha presentado un informe histórico, que suscribo, elaborado por su Comité Ad Hoc, sobre el uso de la IA en la enseñanza, el aprendizaje y la formación en investigación, en el que propone una reorganización profunda de su modelo académico/educativo ante el avance de la IA generativa, entre lo que destaca, entre muchos otros aspectos:
– Diseño inverso (Backward Design): Se insta a los profesores a definir primero qué deben saber, comprender y valorar los estudiantes, para luego decidir en qué puntos específicos la IA suma o resta al aprendizaje.
– Enfoque de aumento, no de automatización: La meta no es prohibir la IA, sino rediseñar los programas y cursos para que la tecnología apoye el pensamiento crítico sin permitir la rendición cognitiva (cuando los estudiantes recurren a la IA antes de intentar resolver por sí mismos un problema difícil).
– Nuevos métodos de evaluación: Se desaconseja el uso de detectores de IA, por considerarlos poco fiables y propensos a generar desconfianza. En su lugar, se propone un mayor uso de exámenes orales, evaluación continua, proyectos prácticos, portafolios con revisiones presenciales y componentes sociales en cada área temática.
El informe propone 8 principios medulares para guiar la integración de la IA generativa en la educación superior:
· Sé humilde (Be humble): Reconocer que el ritmo del cambio tecnológico es demasiado rápido como para establecer reglas permanentes, lo que requiere flexibilidad constante.
· Sé audaz (Be bold): Afrontar la situación de forma proactiva mediante el rediseño profundo de los planes de estudio, en lugar de aplicar parches defensivos.
· Pon a la humanidad en el centro (Put humanity front and center): Priorizar las relaciones interpersonales, el florecimiento humano y el valor de la educación residencial (de humanos enseñando a humanos).
· Sumérgete en el aprendizaje / Preserva el esfuerzo constructivo (Lean into learning): Entender que el esfuerzo cognitivo y la dificultad son esenciales para aprender; obtener una respuesta rápida de una IA no equivale a adquirir conocimiento.
· Enseña con intencionalidad (Teach with intentionality): Diseñar las clases con propósitos claros, evitando tanto las prohibiciones reflexivas como los mandatos ciegos de la IA.
· No hay una solución única para todos (No one size fits all): El nivel de formación importa; una política o herramienta adecuada para un doctorando puede resultar perjudicial para un alumno de primer año que aún está construyendo sus bases conceptuales.
· Aumentación, no automatización (Augmentation, not automation): Utilizar la IA para elevar el nivel de los problemas que un estudiante puede resolver (potenciar el pensamiento), en lugar de delegar por completo la capacidad humana de pensar.
· Piensa más allá del aula y del campus (Think beyond the classroom and the campus): Considerar el impacto de la IA en el desarrollo integral de los estudiantes como personas y ciudadanos en el mundo exterior.

Demanding economic growth has become unfashionable among some people in Europe.
Instead they speak of a “cost of living crisis”.
But it’s really one and the same.
Economic growth means that incomes rise relative to prices.
Economic growth means that the things we need become more affordable.

Across the country, people will claim "roundabouts will be dangerous because people don't understand them."
The truth is that roundabouts have an incredible success rate, both in lowering speeds and reducing severe crashes.
Carmel, IN is our country's roundabout capital. They replaced 120 stop lights with roundabouts and this happened:
🚨 90% drop in fatal crashes
🚨 40% drop in total crashes
🚨 $21.6 million saved in long-term maintenance
(That doesn't even include the enormous financial savings of preventing crashes.)

We need a 100%+ sin tax on elective plastic surgery.
Not only would it raise extremely progressive revenue, but it'd gradually steer medical resources back toward necessary medical care.
Hollywood actress Jennifer Lawrence appears ‘unrecognizable’ on magazine cover while claiming to have only ever undergone one plastic surgery procedure.
The ‘Hunger Games’ star has admitted to having a breast augmentation surgery and ‘baby botox’ while saying she wants to get a facelift in future to be a “sexy mom.”
“I want to be a sexy mom. At drop-off, I want to look like a woman that has her s**t together even when I’ve just woken up and don’t have my s**t together.”
Fans have speculated she has undergone more procedures after they branded her ‘unrecognizable’ during her appearance on the cover of ‘The Cut’ magazine.

EU gas is above €90/MWh, its highest since Dec 2022. Brent is above $115, its highest since June 2022.
The EU has already paid €100bn+ extra for oil and gas since Hormuz closed. Not one extra molecule.
Best defence: electrify.

What most people don't know: when you fill up a petrol car most of the energy never moves it.
Petrol car: 13–21% of the crude oil's energy reaches wheels.
Electric car on today's UK grid: 43–45%.
Electric car on wind+solar: 77–80%.

A new piece in the Financial Times created a great visualization of the results from this study.
TL;DR: Rent control helps people whose rents get limited, but it hurts everyone else. It pushes up rents, pushes down new building, and makes cities worse.
It is horrible policy.

One reason EVs are better, is that they waste much less energy than ICE vehicles.
Electric motor: 85-95% efficient.
Internal combustion engine: 20-30% efficient.
In an ICE, most of the energy you paid for becomes waste.
In an EV, most of it actually moves the car.
That’s why comparing the energy used by an EV with the energy contained in petrol can be eye-opening.
ICE engines are basically very sophisticated heaters that happen to turn the wheels.

Electricity Already Powers More of the World Than Oil
>While electricity is now 23% of final energy, combustion engines and boilers waste massive heat
>Because EVs, motors, and heat pumps waste far less, electricity already delivers 40% of the world’s useful energy, providing more actual energy and work than oil!
Count the energy that actually does work: Electricity powers 45% of global GDP
Electrification is unstoppable

Check out the speed (EV sales growth, YOY):
>Colombia: +304% (Apr 26)
>Brazil: +196% fully electric (H1 26)
>Uruguay: +147% (Aug 26), EVs now 51% of new car sales
>Latin America overall: +74% (Q1 26)
>Mexico: +22% (H1 26)
Now the rest of the world:
>Europe: +29% (Jan–Aug 26)
>Global average: +4% (Jan–Aug 26)
>China: -12% (Jan–Aug 26), yet EVs hit a record 65% share because petrol sales fell even faster
>North America: -21% (Jan–Aug 26)
The world grew EV sales 4%. Latin America grew 74%. North America is going backwards.
The next EV boom isn't in Detroit or Stuttgart. It's in São Paulo, Montevideo, and Bogotá.
