In Ukraine, distributed renewables foil Russia's assaults

    If every building and other piece of infrastructure essentially powers itself, that means to disable a bunch of targets you now can't just disable a central substation that feeds them, you have to disable the targets themselves, and depending on the nature of the targets that may no longer be economical.

    It also no longer makes sense to attack the connecting lines between them as well.

      Disabling them is a means to deal economic damage, not an end-goal in itself.

      People built centralized grids because it's cheaper to build and service when the equipment is concentrated in one place. The economy of scale kicks in.

      If you move to decentralized so there's fewer outages, but now you're paying extra to maintain it, your solution is not as good as it used to be, that's economic damage right there.

      And your enemy probably will also stop targeting the small decentralized grid elements, so they're not spending bucks on missiles. They can use more of them to hit other parts of your economy that are still centralized.

      Estimating the net impact of this change is bigger than the article suggests.

        What does the distinction between economic damage and not being an end goal in itself have to do with anything? Either way it's a live goal being pursued and decentralizing will mitigate Russia's ability to inflict pain.

        You're right that centralized grids are cheaper (as long as the utilities maintaining them are good faith actors) and that switching to decentralized solutions brings new maintenance costs. But this is a war, the choice isn't been idealized central distribution and costs of decentralization, it's between the latter and a grid under siege by missiles. Relying on a grid that's being struck by missiles with no backup plan isn't economical either.

        Also in your other comment you were claiming PV being outside was "much easier to hit" but now you are saying those systems probably won't be targeted.

          > mitigate Russia's ability to inflict pain

          The crux of the distinction I'm making is right there. Russia is not doing some ephemeral "inflict pain", it's pursuing a clear objective of draining Ukraine's budget.

          The way I'd do it if I was in Kremlin is something close to make up a list of targets, rank them by (Ukraine's cost to maintain)/(Russia's cost of missiles), pick the top 3-5 and hit them. Also continuously update the cost estimates and reevaluate those 3-5 targets.

          In this vocabulary, Ukraine moving to decentralized is a cost in itself, so if it does pay that cost to move "energy grid" item down Russia's list, Russia can celebrate it and move on to the next target. If this happens, Ukraine will have paid the cost of moving to decentralized, and will be continuously paying a penalty for it, while Russia's coat of incurring that on Ukraine goes to zero (since the new missiles are hitting different targets).

          And critically, if we assume moving to decentralized will make it pointless for Russia to hit the grid, deciding how much will it help requires knowing what target they will aim those newly freed missiles at, and how much cost that is going to incur.

          > you were claiming PV being outside was "much easier to hit" but now you are saying those systems probably won't be targeted.

          These are all hypotheticals, I assumed we're on the same page about it. We don't really know here in this forum what's going to work. Considering two contradicting hypotheticals in different threads is alright.

          My comments are not about what is true, what's going to actually happen on the ground. They're about how one should go about arguing whatever they're arguing for, what reservations they're missing, and what assumptions they made they're not aware of.

            This is not true - they’ve regularly targeted and hit kindergartens, supermarkets, gas stations, town squares/markets, residential buildings, etc. None of these targets are “budget draining” but instead are intended to terrify and hurt civilians. Russia isn’t calculating or being strategic at the level you suggest - instead its actions are often simply cruel, inhumane and vindictive even at the cost of its own strategic interests.

              I agree that they hit civilian targets, the evidence is there. How do you know they targeted them? Missiles sometimes can miss or or be shot down by air defenses, then fall and explode.

              It's been broken down many times with a lot of examples from history: harassing civilians only mobilizes them. So Russia must be not only cruels but also stupid if you want to argue that they're targeting civilians.

              The death toll among civilians also does not look like they're being targeted, more like collateral damage. Typically when you see a headline like "another bloodthirsty attack of Russian orcs of Ukraine's civilians", you open the post to see that there's 4 dead + 15 injured. Like if they had a goal of killing civilians, they wouldn't do it by hundreds.

              It's cheap to demonize and dismiss the side you don't like, picture them as cruel, stypid, evil. And from there, creatively explain everything they do with these qualities. It seldom helps you understand reality though.

              So it could be that your case is special, you're not just being lazy and racist in building your worldview, but people you don't like are actually unreasonably cruel, evil and also stypid. Or maybe not, and your explanation is lazy and of poor quality. Guess which one is more likely.

                Double-tap attacks are a tell-tale sign of this. If half an hour later another missile or a drone "accidentally" hits exactly the same spot to kill rescue workers, there's not much mystery left.

                Modern drones and missiles are rather ineffective for killing lots of people. Most of them get shot down, and those that reach their targets have relatively small warheads. Nothing compared to old-school area bombing. A typical major air raid (500-800 planes) in WWII delivered 2000-4000 tons of bombs to a single city. A typical 200-drone strike in 2026 delivers potentially no more than 10 tons spread across the country, probably even less if we account for decoys. The largest strikes (drones, cruise missiles and ballistic missiles combined) had about 40 ton payload, of which 10 tons reached the intended target. In WWII terms, that's about 3 planes' worth of bombs.

                  Good points, didn't know that.
