"By analyzing the flow of record fossil fuel profits after Russia’s invasion of Ukraine in 2022, researchers found that the wealthiest 1 percent of Americans reaped about half of the benefits". Important per entendre per a qui funcionen les polítiques de Trump...

Knittel (MIT): “We’re likely at this inflection point where costs are going to start growing more rapidly. The observed costs have been fairly linear so far. Going forward, that’s going to start increasing at an increasing rate.”

A la llista de LV dels "Municipios catalanes [que] se blindan frente a las renovables cambiando normas urbanísticas" hi ha les Franqueses del Vallès. Un municipi que està fotent un polígon d'activitat al mig del connector biològic del Carbonell. Per ponderar les seves preocupacions ambientals...

"En 2005, estas tres grandes compañías (Iberdrola, Endesa y Naturgy), a través de su dominio nuclear, térmico e hidráulico, generaban en torno al 80% de la electricidad. Hoy, con la proliferación de actores construyendo centrales eólicas y fotovoltaicas, el "big three" pelea por no bajar del 50%."

Romania has decoupled economic growth from pollution faster than anywhere else in EU. Its net greenhouse gas emissions intensity fell 88% between 1990 & 2023, so each euro’s worth of economic activity heats planet 10 times less. Emissions have plunged by 75%. www.theguardian.com/environment/...

Solar + 4 horas de baterías en India: 58€/MWh. Y pretenden que la nuclear compita con esto... www.pv-magazine-india.com/2026/02/06/a...

La única cifra oficial de casas sin uso, obtenida a partir del censo de 2021, señala que hay 3,9 millones, pero los expertos recelan de ella. La falta de datos fiables complica la movilización de la vivienda vacía en España

"Crops convert less than 1% of sunlight into biomass; solar panels convert around 20%. Add the efficiency gains of electrified cars over liquid fuels, and the efficiency gap widens further." open.substack.com/pub/hannahri...

"High-profile economic studies claim to quantify global damages caused by CC centuries into the future, with estimates ranging from modest to catastrophic. Economists like me, trained to think about trade-offs, are uneasy with both camps, although we have helped fuel this dysfunctional debate".

Not a single day in 2025 was cooler than the 1991-2020 average, on a global scale. @copernicusecmwf.bsky.social

"China’s recent clean-energy generation growth, if sustained, is already sufficient to secure a peak in coal power. Similarly, India’s clean-energy targets, if they are met, will enable a peak in coal before 2030, even if electricity demand growth accelerates again."

Subasta solar en la India. Ojo al precio. 1,2 GW solares + 0,6 GW/3,6 GWh de almacenamiento en baterías (3 horas respecto a la potencia pico solar, pero 6 horas para entregar la mitad de esa potencia). Precio: 30€/MWh...tremendo. www.pv-magazine.com/2026/01/12/i...

Ha estat difícil resumir dues síntesis en un article, així que recomano fer una ullada al document complet (ivalua.cat/ca/projecte-...) on intentem aterrar aquestes conclusions al context català i generar debat entre els agents implicats en el disseny i la implementació de polítiques públiques.

Country 9 in global oil reserves has invaded country 1 and arrested its president. Country 7 is under sanctions and its refineries are being destroyed. Country 2 is facing off with country 6. And there are riots in country 3. But oil is only $60/bbl. Maybe oil is not as critical as it used to be?

No recuerdo haber leído nunca un artículo tan contundente sobre el fenómeno Nimby, al menos por parte de un periodista. www.diaridetarragona.com/economia/248...

1/Lo del Automotive Package me parece tremendo. Qué absoluta incomprensión de la era en la que está entrando el mundo. Qué incoherencia entre una regla y otra, entre lo q se dice y lo q se hace. Un equibrio q ignora q no podemos seguir en la época de la política de... ec.europa.eu/commission/p...

"Stopping [methane] leaks is seen as one of the most easily achievable climate fixes", and the U.S. has already invested billions of dollars in detecting them. However, "this is about the Trump administration pushing Europe to purchase hundreds of billions of dollars in U.S. oil and gas”.

"While it can take a coal plant about 12 minutes to get going, batteries can discharge power almost instantly." Batteries as an alternative to peak plants.

Europe is under siege

"If you want to understand what’s happening on global energy and climate, you need to be following China closely."

No se podía saber...

Gaaas! (expressió que, d'altra banda, hauríem d'anar canviant...)

Where are we a decade after the Paris Agreement? The good (-ish), the bad…

“The idea that there is a binary choice between health and climate is an idea that’s been roundly rejected by virtually every scientist in this field, and the World Health Organisation has said long since that climate is the No 1 health threat to humanity.”

Aquesta setmana comença la #COP30 🌍 Mentre es debaten grans acords, hi ha petits canvis que podem fer a Catalunya per reduir emissions. En @jacintenrich.bsky.social explica què funciona per millorar els hàbits de consum energètic de les llars. 🔗 ivalua.cat/ca/revisions... #QFCanviClimàtic

Australia to offer three hours free solar per day to millions: Great demand response initiative! And not only from an efficiency perspective, but also for sharing the benefits of solar with those who don’t have panels, including renters.

L'altra cara de la moneda és que gràcies a les renovables, la propietat de la producció d'energia està més repartida, reduint així la gran concentració del sector! elperiodicodelaenergia.com/las-empresas...

“It’s not about climate politics anymore, it’s about climate economy”. And, although it is hard to be optimistic, clean tech can bring an end to energy poverty globally...

US fossil fuel companies receive $31bn a year in subsidies. Add that to the ~$600bn handed out globally in consumer fossil fuel subsidies every year, and then let's discuss whether renewables can survive without subsidies...

China is quietly saving the world from climate change

“For too long, emerging economies have faced what seemed like a stark trade-off between growth and sustainability. The Chinese dominance of clean-energy industries is challenging that assumption".

"Without climate change, similar ten-day spells of hot, dry and windy conditions would be rare, expected once every 500 years, the World Weather Attribution group found."

Even if China's emissions fall in 2025 as expected, it is bound to miss multiple important climate targets this year, such as a reduction in carbon intensity and curbing coal use.

Huge thanks to the dozens of climate scientists who sent us their rebuttals to the catalogue of outright falsehoods and misleading claims in Trump's new 'critical' climate report. This factcheck is the longest article CB has ever published - 27,500 words already and likely to keep growing...

"In 2015, the Chinese government announced 'Made in China 2025', providing companies in 10 strategic industries with large, low-interest loans from state-owned investment funds, help in acquiring foreign competitors and subsidies for scientific research." The results of Industrial Policy in graphs!

Sad that a useful tool to adapt to climate change has been dragged into a sterile political debate

"The rebate payment was a compensation to maintain disposable income, but when it was sent to Austrians, the money remained in savings accounts and didn't go to consumption.” A nice real-world policy experiment on the effectiveness of the tax-rebate instrument!

“Over the expected lifetime of these products, their manufacturing emissions will be offset almost 40-fold, with cumulative CO2 savings reaching 4.0GtCO2” (or around 10% of world annual emissions)

“In the absence of robust U.S. climate action, the EU and China still recognize the imperative of working together to confront a shared existential threat.” A much needed signal in these dark times…

“Solar power had seen plunging costs of production, making it all the more alluring not just from a climate-change standpoint but also from a national-budget one.” Now add the staggering battery cost decline already underway and the missed opportunity hits even harder…

“Interests are shaped by ideas. In order to figure out whether we gain or lose from a particular policy, we need to know how the policy will play out in the real world, and also what would happen in the absence of the policy. Few among us have the ability or inclination to figure it out.”

The Trump administration stops estimating the most important number you’ve never heard of…

“The U.S. will champion a fossil fuel economy, and China will become the leader of the low-carbon economy. The question for the U.S. now is, where do you go from here?” www.nytimes.com/interactive/...

They're* calling it the blackout bill. With new demands from AI, hotter temperatures, and the return of U.S. manufacturing, pulling back on clean energy deployment puts our electricity system at risk. *ok it's just me but still

The energy provisions in the Republicans' One Big Horrible Bill are truly so bad! Who wants this? The country's automakers don't want it. Electric utilities don't want it. Data center developers don't want it. Manufacturers in energy intensive industries don't want it. 🔌💡
