The EU itself is a thing to behold. Just managing to prevent wars between their members for so many decades is a remarkable accomplishment, unheard of in the continent's troubled history. Not perfect, and certainly not invulnerable to bad actors, but still a beautiful accomplishment of will and politics.

Almost all of us in Europe have never known anything but this peace so it almost feels a given. (I doubt a lot of readers are above eighty years old.) Yet a lot of kvetching about regulations happen and so it's good to remind people they have their own use.

Surely you mean this peace that ended when Russia started a full-scale invasion in Ukraine.

I found this article from bloomberg on the event! > Europe’s grid, which is usually connected from Lisbon to Istanbul, split into two as the northwest and southeast regions struggled to keep the same frequency. The problem originated in Croatia and led to the equivalent of 200,000 households losing power across Europe. Supply to industrial sites was cut in France and Italy. > Transmission grids need to stay at a freq…

And the work to speed up Moldova & Ukraine's connection to the sychronous grid, just after Russia invaded in 2021, was impressive too.

You meant 2022, right? I'm linking an article describing how Ukraine connected to EU grid

I've come to think that the so-called "most peaceful era in human history" as the post-Cold War era has been often called is more aptly "most peaceful era in western history".

Plenty of strife and conflict can be and are found where most western eyes generally don't look.

This is why the common trope of "The grid can't function without the inertia from big heavy generators!!" detracting the rise of renewables is invalid. Synthetic grid strength has been available for a century. Today the research focuses on "Grid forming inverters". Taking the same principle as powering a home in island mode and stretching it to the entire grid allowing non-synchronous generators to provide the system…

this article is about using very high mass alternators to stabilize the grid's frequency

Oh yes, 2022.

The headline implies the Baltic states will have an independent electricity grid, but it's just switching dependence from Russia to the EU (for electricity) and the USA (for liquified natural gas imports). Lithuania, Estonia and Latvia would be better off eliminating those dependencies entirely by focusing on expanding their domestic renewable energy production infrastructure.

Lithuania has more solar installed than Spain or Germany (percentwise) and been hitting 40-60% renewable supply for few months now.

You don't need that, the official report is good https://www.entsoe.eu/news/2021/07/15/final-report-on-the-se...

Official reports can be self-serving, both intentionally and unintentionally (it represents only one perspective). Journalists talk to many sources with many perspectives.

Journalists might but the publication which did the supermicro spy chip story without retracting it does not deserve that moniker. (Small footnote: I was a columnist, later editor, even later part of the editorial board of the largest computer monthly in Hungary in what now feels like a different life a quarter century ago.)

This peace, by and large, is about the lack of entries with other Western European countries on https://en.wikipedia.org/wiki/List_of_wars_involving_Germany

By that measure, you'd consider the peace ended in 1956 when Russia -- then called the Soviet Union -- re-invaded Hungary after very briefly withdrawing. (As an aside, when the National Bank of Ukraine last year opened two donation accounts, I sent 1956 EUR to both. I am not subtle with my messaging.)
