Because of the Nobel Prize, a lot of people will be talking about neutrinos today (including me I’m sure)! I *also* talk a lot about neutrinos in my new book, “How to Build a Universe (Theoretically Speaking),” which is available for preorder now! www.astrokatie.com/book-htbau

Natalia Fabra & Mar Reguant argue that the binding constraint on the energy transition is no longer technology but market design. Fixing it means rethinking how renewable energy investment is financed and how demand is brought along. cepr.org/voxeu/column... #EconSky
Figure shows economy-wide electrification rates in the EU, China, US, Australia, Japan, and South Korea. With an electrification rate of only 24%, well below China’s 34%, Europe still requires substantial additional clean generation to reduce its dependence on fossil fuels.

Solar and wind have become the cheapest sources of new electricity almost everywhere, yet Europe is now switching them off in record numbers. This column argues that the binding constraint on the energy transition is no longer technology but market design — and that fixing it means rethinking how renewable investment is financed and how demand is brought along.

Because Trump is mad at our closest ally, Canada, he decided to buy potash (a key fertilizer ingredient) from one of the world's most notorious cruel dictators, Belarus' Lukashenko. Typical for Trump, he didn't bother to check before announcing his big deal. Belarus doesn't have any potash to sell.

Karikatur zum Thema hohe Benzinpreise. Eine Frau steht ratlos an einer Zapfsäule mit der Aufschrift „Fossile Oil“ und fragt: „Benzin ist so teuer – was tun?“ Daneben werden drei Möglichkeiten vorgeschlagen: weniger und langsamer Auto fahren, ein sparsameres Elektroauto kaufen oder gegen die Benzinsubvention protestieren und die Regierung beschimpfen. Die Zeichnungen zeigen dazu einen stark qualmenden Geländewagen, ein Elektroauto mit Fahrradfahrer sowie einen Demonstranten mit Benzinkanister und dem Schild „Benzin-Menschen-Recht“.

The accounting is in: In Oregon there are 111 data centers. The TOTAL number of people employed at data centers is just 2,630, or 0.1% of the labor force. Those 100 data centers consumer 23% of all electricity used in Oregon. Meanwhile, electricity rates skyrocket as more centers are built.

The US ambassador writes in bad faith. The US tariff taxes output. Exemptions are allowed for firms who pay bribes or share special secrets with Trump and Epstein. The CBAM taxes carbon emissions. Firms with no emissions or a domestic price pay no tax. Who’s against rules based trade?
