The West’s Last Chance How to build a new global order before it’s too late.

"This is the last chance for Western countries to convince the rest of the world that they are capable of dialogue rather than monologue, consistency rather than double standards, and cooperation rather than domination."

Energy note.

This video on new wooden towers for big wind turbines is nicely done. It will be interesting if they catch on, especially with larger and taller turbines.

How the US cut climate-changing emissions while its economy more than doubled A fast drop in coal use played a big role, but there was more, as these charts show.

'U.S. emissions from many of the activities that produce greenhouse gases – transportation, industry, agriculture, heating and cooling of buildings – have remained about the same over the past 30 years."

I'm no expert on what AI can and cannot do right now with texts. You may be right.

I currently use it to write simple short stories in foreign languages at appropriate levels (A1, etc.) and it seems to be fine at that. I find it useful even if it's not perfect.

It's testable for anyone motivated.

There seems to me to be suspension of disbelief items in most stories. Short writing deadlines at work here?

I've started watching "Away" on Netflix and it has me going "are you kidding me" multiple times an episode so far.

Maybe writers will query AI systems to look for them in the future?

Chinese Firm Plans World’s Largest Wind Turbine as Rivals Flop Ming Yang Smart Energy Group announced plans to build the world’s largest floating wind turbine, as Chinese firms seek a larger share of the global market while rivals grapple with rising costs.

The idea that there's a 50 megawatt wind turbine being built blows my mind. The reduction in the cost of off-shore power from it is even more incredible.

Spain’s Renewable-Energy Boom Loosens Gas’s Grip on Power Prices Soaring renewables output in Spain is weakening gas’s grip on electricity prices, setting the country apart from much of Europe where fossil fuels still dictate the cost of power.

"Spain’s rapid renewables build-out means that in the first half of this year, its power prices were set by fossil generation just 19% of the time, down from 75% in 2019 ... wholesale electricity was almost a third cheaper than the European Union average."

Ever higher electricity costs to consumers. Why?

Trump says he plans to designate antifa as ‘major terrorist organization’ It is unclear how anti-fascists, an umbrella term for far-left-leaning groups rather than a single entity, will be labeled

There is no organization called "antifa" - so, why label a non-existent group "terrorists"?

This gives the regime maximum scope to hunt down opposition and critics. They label you "antifa", and then they come for you.
