   This is greenwashing.

   The article suggests that renewables are somehow more helpful in a war when your grid is targeted by drones and missiles. It doesn't do a comparison to back it up though.

   Decentralized power production vs. centralized does make sense: decentralized doesn't offer a single point of failure taking out which causes a lot of damage.

   But can't energy from fossil fuels be generated in a decentralized manner too? Sounds only better than renewables because it doesn't go up and down throughout a day, and doesn't need grid to amortize the jumps.

   Renewables sort of need to be out there in the open to harvest energy from the elements. Solar needs sunlight, wind needs to spin its huge blades in open air. A diesel generator, on the other hand, perfectly goes underground, much harder to target.

   So the article doesn't really establish that renewables offer a clear advantage over fossils in a war.

   Upd: some comments below have convinced me that fossils don't decentralize as easily as renewables.

      If you sit on an oil well, perhaps. In practice every static part of the production and distribution chain is a centralized target: from wells over refineries to depots, roads, harbours and finally power plants. You simply can't run fossils in a distributed local-first approach. That's also the reason why even for a massive oil producer like Russia, Ukraine can cause billions in damages with drones costing a couple hundred grand.

         Right. I think the most optimistic take would be that vegetable oil with some processing, can be used for diesel but I'm not sure how practical that is or how reliable access to waste vegetable oil is

         Fair!
