Yes. Because it's real. Because it's cheap and it's a good idea.
Solar still wins.
Even without any of the many exaggerated claims of climate catastrophe, climate apocalypse, climate disruption or whatever the propaganda will call it tomorrow.
This, too, is because of desperation.

This is why Donald Trump had to be made president by his fossil fuel handlers: desperation. Why he fights climate science on their behalf: desperation.
US media have failed miserably at pointing out the lies and the damage the climate crisis is doing already. Solar still wins.

European governments are tightly connected to the American government. There are just as many Trumpists over here as over there.
Fascism has always had roughly equal support in all western countries, including the 1930s. But it didn't gain power everywhere equally. Just like today.

The most interesting parts of this map are the ones with no data. I wonder about the reasoning behind that. It's not like dire deprivation doesn't happen in in the west, or in ... Russia. (My guess is that it's an ideological Cold War left over.)

A thousand years from now, historians will be debating five different, completely rational reasons for why the American Empire collapsed, when the reality is the country was taken over by braindead loons & their retinue of low agency simps.
This probably holds for other historic collapses as well.

The U.S. currently has more prisoners and a more sophisticated system of concentration camps than Nazi Germany had on the eve of World War II in 1939
ICE has now spent over half a BILLION dollars just on purchasing warehouses around the country to convert into detention camps.
If these mega-camps are utilized to the full capacity ICE intends, they'll be the largest prisons in the country, with little real oversight. www.ajc.com/politics/202...

The only way to work less, is to actually work less.

“You had thought that maybe, oh, because you could be more productive with AI, then you save some time, you can work less. But then really, you don’t work less. You just work the same amount or even more.”

Because employees could do more, work began bleeding into lunch breaks and late evenings. The employees' to-do lists expanded to fill every hour that AI freed up, and then kept going.

I can't count the number of times I've been told that sodium ion batteries are useless for regular EVs.
🔋CATL and Changan have announced the first mass-market EV with a sodium-ion battery.
The sedan finished its cold weather tests at -40 C and uses CATL’s Naxtra batteries.
This is another testament to the growing commercialization of sodium batteries.
