I have to be blunt and just say outright that I find
@ember_energy (at least the central team) increasingly ridiculous.
Even in the zero-carbon electrostate future that Ember would endorse in a heartbeat, there will be vulnerable centralized bottlenecks--hydrogen pipelines, petrochemical plants, hydrogen peaker plants, offshore wind substations, HVDC converter stations, undersea cables (e.g. Greece to Crete or Morocco to Spain).
What is the cost and time to repair of a 20MW offshore wind turbine? What if a drone hits the receiver tower at a concentrating solar farm?
Virtually no mention of cyberwarfare, which arguably renders modern grids of all configurations more or less similarly vulnerable.
And acknowledging that Ukraine has demonstrated solar's usefulness for grid resilience while under constant Russian attack, open war really isn't one of the leading considerations for most countries' energy system design. There are a lot of good cost and operational reasons why a heavily distributed energy future very well might not prevail over centralized models. And in practice future systems might easily qualify as some hybrid of both. Pooh-poohing "centralized=bad" is just, well, kind of stupid.
