Um, 🔌💡 -- looks like Utah just legalized "balcony" solar systems under 1200W. No permit, no interconnect agreement, no NEM. Just need to have a safety shutoff, meet NEC, and UL certification. le.utah.gov/~2025/bills/... Is there a certified product available in the US, @commercialsolarguy.com?

This is Marco Rubio explaining how the USA promised to defend Ukraine forever if they got rid of their nuclear arsenal left after the Soviet Union fell. This is why lil marco was sinking into the couch. He was hoping we wouldn’t find it…so don’t RT right now this very second.

Fingrid data shows #electricBoilers go full 500MW immediately as spot power price drops near zero. Extrapolated 10x, like from 🇫🇮 to 🇩🇪, suggests that during a windy christmas week E-boilers could offset 800 GWh natural gas in heating, saving Germany 40 million € imports and 170ktCO2. In one week.

WOW. After yesterday’s Oval Office ambush of President Zelensky, Haltbakk Bunkers, one of Norway’s leading marine fuel providers, announced that it will no longer refuel U.S. Navy vessels, urging other European firms to follow suit. The United States is weaker and more isolated than ever.

In January an American military police serving in Germany killed a mother of four near Nuremberg. He drove an SUV on duty, apparently fell asleep, off the road, through roadside bushes and hit the woman as she walked on a parallel footpath. Initially he lied that the woman had run over the street.

One thing Germany and US have in common is the love relationship with cars. Cars are allowed everywhere, parking is cheap or often free. Municipalities urgently need income but congestion charges are vehemently rejected. Luckily, Germany also has good public transport and the #Deutschlandticket

German cities have announced the dismantling of the gas grid. Cities like Mannheim and Hamburg are leading the way. Mannheim plans to shut down its gas network completely by 2035. More in my article with @ckemfert.bsky.social on The Progress Playbook. theprogressplaybook.com/2025/02/19/a...

#Verbrenner: Ein 100 Jahre altes Geschäftsmodell geht WELTWEIT seinem Ende entgegen. Der Rückgang hat nichts mit den Grünen oder Robert Habeck zu tun, sondern mit Marktsättigung. Lassen Sie sich nicht von Frau Weidel, den Herrn Merz und Lindner sowie von BILD und WELT belügen!

German media fact checks far-right AfD party leader Weidel's claims on energy, exposing lies: Power prices in Germany are not highest in the world. Building new nuclear plants would not lower prices. Her earlier promise to tear down wind turbines would raise prices www.tagesschau.de/faktenfinder...

It was an honor to sign the guest book in the home of Anne Frank. I was here as a younger man and thought about her life as a dark chapter of history. Today, I can’t help but think of her story as one of caution. Our world is fragile, and it’s incumbent on us not to break it.

“The more we’ve learnt about how to do nuclear power, the more expensive it’s got. That’s the opposite of what usually happens.” Quote from Prof. Bent Flyvbjerg in great piece by FT on why so many nuclear projects get a) delayed and b) are over budget. www.ft.com/content/5e56...
