"The political headwinds against climate action have intensified, even as temperatures reach record highs. But even if some countries step back, others need not give up. Change is still possible; the challenge is whether policymakers are willing to design the incentives that make it inevitable".

"The economist Gabriel Zucman said France had raised 69 million euros instead of an estimated €3 billion. Why? Companies shifted profits either to tax havens or to countries where the oil was produced instead of consumed." Alternativa: impostos a les vendes nacionals i no als beneficis nacionals.

"One hopes the world will recognize that the “variability” of sun and wind power is far more manageable than continued dependence on fossil fuels, which are subject to the whims of erratic authoritarian figures like Trump and Russian President Vladimir Putin".

Una de las cosas más irónicas de las renovables es que donde se instalan paneles fotovoltaicos suele haber más biodiversidad, principalmente porque implica que ahí hay menos actividad humana (agrícola y de otros tipos). www.ecoportal.net/en/solar-pan...

A favor de mesures que millorin la competitivitat de l'electricitat respecte els combustibles fòssils

"Las baterías han comenzado a arrebatar al gas el papel de equilibrador del sistema eléctrico, ofreciendo una respuesta mucho más rápida y limpia para gestionar los ciclos de demanda"

Solar panels in the rain? No problem.

"Spain is emerging as a good student."

Se m'acuden moltes maneres d'endosar el cost de les externalitats negatives del turisme a l'erari públic, però aquesta és particularment perversa: "Los sindicatos piden que se reserven viviendas públicas para los trabajadores temporales en zonas turísticas".

The next tipping point in the energy transition is approaching. Overall, solar has already been cheaper than fossil power for a while, but upfront costs used to be higher. That's no longer the case. Solar is now competitive upfront AND has vastly lower operating costs (no fuel).

"In the history of our species, no biological creature has ever existed absent energy-scarcity. We could be the first species to be in a state of energy abundance, of having all the energy we want or need, but you can’t get there with fossil fuels, only clean energy can get you there". @volts.wtf

L’avaluació d’impacte ambiental prèvia a la construcció del parc estimava 13,5 col·lisions en els 19 mesos analitzats. El model de risc de col·lisió aplicat a l'ACTIVITAT REAL OBSERVADA resulta en 0,002 col·lisions. @renovemnos.bsky.social renovemnos.cat/les-dades-de...

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.”

"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/...

"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".

"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...

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?

"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.

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...
