    Fossil fuel supply chain makes your country very vulnerable!

    https://github.com/Lkruitwagen/global-fossil-fuel-supply-cha...: The resulting complex network has 6.09mn nodes and 15.70mn edges and is implemented in a graph database. With estimates of annual coal, gas, and oil demand in 13,229 global population centres and 8,165 global power stations, we use a minimum-cost flow method to estimate global asset-level energy flows.

    If you want to protect your country, here are your options:

    1) Invest in nuclear power and nukes (source of Uranium may be a concern). See North Korea vs Iran.

    2) Solar on every structure, every vehicle is an EV. This will be the most resilient, distributed grid that can never be disrupted. Node level failures (hail on roof breaks solar) can be easily overcome. EVs are batteries on wheels! They can go charge and come back. Some on this forum may be familiar with Cattle vs Pet, Redundancy, Resiliency, Virtualization (--> Virtual Power Plants), etc -- same concepts, but applied to power generation which is designed as a monolithic circuit switched network. The idea of energy as packets, which can be Store-and-Forward (using batteries) will change everything we know about energy.

      Maybe if the EV is an all-terrain truck because roads and bridges etc. are still vulnerable.

      > Invest in nuclear power and nukes > See North Korea vs Iran.

      Both countries invested in nukes (it is claimed). Only Iran didn't get there in time, before the US stepped in to stop them (it is claimed). So unless the US lets you, it's probably a bad idea to invest in nukes, no? Or is your point that the US's nuke story was a lie, and that Iran actually should have invested in nukes?

      > Solar on every structure, every vehicle is an EV

      Have you done any calculations as to whether this would actually work? My gut feeling is that even if you put solar panels on literally every structure, you'd be far off from managing to power every vehicle. See if I get around to calculating later, but I at least advise you to do so yourself before making this argument.

      > EVs are batteries on wheels! They can go charge and come back

      Uh... Cars are fuel tanks on wheels...

      • RobotToaster 8 minutes ago
        The moral of the story is you should always invest in nukes, since if you don't the US will just lie and say you are developing nukes as a pretext anyway.

        This also applies to WMDs in general.

      • thelastgallon 31 minutes ago
        Sure, do the math and get back.

        First, do the math for millions of acres of Ethanol, a small fraction of fuel additive.

        Using the same acres for solar with be sufficient for the entire energy (all forms of energy) many times over.

        • streetfighter64 26 minutes ago
          Look man, why haven't you done the math? It's your argument after all. Anyway, a very optimistic calculations means you need the flat area of at least 800 m^2 in a sunny climate, to charge a single electric truck to full power. Plus you need a battery bank to store it during the day, supposing you're charging at night.

          So, now you do the math how many trucks and how much area for solar panels a typical military has.

          I don't need to do any calculations for combustion engines: IT'S WHAT THE MILITARY IS USING RIGHT NOW TODAY!

        • sandworm101 12 minutes ago
          I have done the math, several times. The last time was to biult a hypothetical solar "highway gas station" capable of charging 100 teslas EVs per hour 24/7/365. Assuming flat ground at Vancouver's latitude, it came to a solar farm covering several square kilometers/miles.

          10kwh x 100 x 24 = 24,000kwh Solar panels nominaly produce 1000kwh/m so 24,000m2 of panels... if facing the sun perfectly during normal day/night cycles. But non-equator latitudes need far moe land than that, plus winter, plus rainy days... it is a massive structure just to replace an average highway gas station.

      • thelastgallon 35 minutes ago
        > Uh... Cars are fuel tanks on wheels...

        Sure, but you don't have inexhaustible source of crude oil and a refinery in your backyard!

        But Sun reliably shows up most days. It doesn't ghost. Sunlight can't be sanctioned, tariffed, taxed, embargoed, pirated, nuked, rebuked, rebuffed, offended. Sunlight is also compatible with most religious beliefs (god is light, etc).

          > a refinery in your backyard

          Funny thing is, fuel can be transported, so that's not needed!

          If you want to look at the geopolitics of it, all of the bigger countries do in fact have their own sources of oil and their own refineries.

          And if you're going the solar route, you still need the raw materials to build the solar panels (and batteries, and EVs) in the first place. They don't grow on trees.

          I'm sure we'll see a transition to electric some day, it is more efficient purely from a physics standpoint. But I'd be shocked to see the military transition before civilian industry.

          • rcxdude 6 minutes ago
            Most countries do not have enough to independently supply their own energy needs from fossil fuels, and they need to import more or less continuously, while renewable energy infrastructure needs building out and then lasts a very long time. This massively affects the strategic effects of losing your supply: one becomes an acute problem very quickly while the other is still a problem but it takes a lot longer to become a real problem.

            I don't think the main focus is on converting military operations themselves to work without fossil fuels, but more that if you can convert your civilian industry then you have a much better overall strategic position because your total demand for fossil fuels is much lower. (Strategy is a lot more than just your military)

    If you want security the concept of the mega city needs to be abandoned.

    In a decentralized country you don’t care about terrorism attacks, nuclear bombs, coups, revolutions, drones and what not.

    • theplumber 12 minutes ago
      Trading off efficiency for security is not wise unless you are in war. The same applies to supply chains.

    Gas and diesel generators are charging small batteries (3coflow types), at least on the frontline because solar panels are good ways to invite incoming fires

    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.

    • gnull 53 minutes ago
      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.

      • glenstein 39 minutes ago
        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.

  • mitxela 28 minutes ago
    They are also the cheapest source of energy with the fewest dependencies. The last part is why they will remain illegal. The power structures of society will do anything to maintain themselves.
  • jmyeet 1 hour ago
    I've been thinking about this (more [1]) and I do believe smaller grids will be the future for many reasons. I guess this is another reason. But the transition from large grids to small grids has no obvious, easy path because a large grid without total market saturation falls apart as maintenance is averaged over fewer and fewer users.

    One side benefit though is that it would stop utilities being able to push data center costs onto consumers, something that regulators and governments thus far seem completely unwilling to do.

    Oh and distributed infrastructure and leadership (the so-called "mosaic defense") is (yet) another reason why the Iran war was always unwinnable from the start.

    • thelastgallon 49 minutes ago
      Indeed. The future is off-grid and community level mini/micro grids.

      There is no need to build/maintain transmission network.

      Legacy grid is production in far away places, miles and miles of transmission, then a distribution network. The distribution network built for homes is sufficient for homes to participate in grid for redundancy. All buildings can produce energy. Rooftop is proven. Next is vertical solar-- which adds ~4 hours of production. EVs become a storage reservoir and supply power back to the grid (V2X). Add some BESS if needed.

      Villages in developing countries (half the population in Asia, Africa) can go completely offgrid. Start with plugins, slowly upgrade to bigger panels. No transmission network needed.

    • MomsAVoxell 48 minutes ago
      The transition is off-grid.

      The technology and the means are there - whats required is the willingness to adopt to the self-powered lifestyle.

      Many, many folks have done this - stepped off the grid and live on self-harvested local energy sources - however, the grid is powerful.

      It is difficult for entire cities to do away with it so rapidly .. at least until PV harvesting gets a significant order or two cheaper and more efficient…

      I think it’s pretty obvious that electric transportation needs to fully adopt integrated energy harvesting. This seems to be an obvious legislative low-hanging fruit.

    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.

    • sigmoid10 51 minutes ago
      >But can't energy from fossil fuels be generated in a decentralized manner too?

      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.

      • glenstein 47 minutes ago
        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
      • gnull 26 minutes ago

    • Lio 23 minutes ago
      A diesel generator needs a supply of fuel that can be trivially blockaded as Iran is so successfully doing.

      The whole world is suffering from the effects of that disruption.

      The supply of diesel itself also requires refineries and they can't be moved or rebuilt quickly either.

      Ukraine is doing a sterling job of attacking Russia's refineries. All the portable diesel generators in world won't help you invade another country if you have no fuel to run them and no supply lines.

      A small repurposed balcony setup costing a few hundred dollars will run every day and keep you alive. There's nothing the enemy can do about it other than a direct hit and that would take out your generator and fuel anyway.

    • hdgvhicv 53 minutes ago
      A drone blows up 1kWp solar panel you lose about 1Mwh in a year assuming it’s completely broken.

      A drone blows up an oil carrying road vehicle you lose 350Mwh instantly.

      You blow up a pipeline you knock out 1 million MWh a day

      • gnull 44 minutes ago
        The drone will disbale more than one of those 1kW panels if it hits an array of them. Panels are stationary, easier to target than vehicles.

        Could you also motivate the choice to compare Wh of energy lost, instead of, say, US dollar cost of the damage? Sounds a bit odd, because Wh is not the currency I pay bills with.

        How much does it cost to replace an array of solar panels, compared to the cost of sending another diesel truck (and paying for the destroyed one + its fuel)?

        • glenstein 18 minutes ago
          >Could you also motivate the choice to compare Wh of energy lost, instead of, say, US dollar cost of the damage?

          Well there's an integral relation between the two, more kWh lost is more dollars lost. They both proxy for some venn diagram overlap that includes damage, cost, lost resources, and it's perfectly legitimate to reason from any permutation of those. It's notionally possible for different tech to attach those costs in different ways but in this case I would put the burden on you to explain the practical difference that you think cashes out in an advantage diesel has.

          I'm not sure why you think a truck would be cheaper necessarily: smaller PV systems can range from $10k to $20k with no fuel payload. Is a diesel truck with a full payload of fuel really cheaper than that? And is a diesel truck supposed to be fueling just one house? It's likely a single point of failure for a network of people depending on it at a time when bridges are getting bombed, and therefore an instance of centralization and attractive target for attack. And you said yourself you didn't think PV would be attacked because decentralizing in and and of itself inflicted the economic damage yet you've once again gone back to imaging a diesel advantage in the event on PV getting attacked.

          > Panels are stationary, easier to target than vehicles.

          Panels are small, numerous and widely dispersed, easy to install quickly and incrementally, and non-flammable.

          Basically the opposite of (also stationary) centralised fossil fuel infrastructure.

          It's clear which one is the more tempting target if you have a finite stockpile of drones.

    • thelastgallon 43 minutes ago
      Remotest villages in India were doing gobar gas plants in 80s/90s. What you are saying is possible.

      If you have enough cows/biomass, perhaps you can have a home biomass to methane converter. Then you can use it for cooking, heating, etc.

      You can convert a petrol car to a CNG car.

      You could also have a coal to liquid plant in the backyard and generate diesel or petrol.

      You have to do without any cooling though, fridge, AC, etc. Cold can't be created. Without electricity, just with chemicals fuels, it is unlikely.

      • glenstein 9 minutes ago
        I don't think they have to worry about lack of access to cold for the next few months. I believe you're accurate re: India and sources of biomass in that context and the possibility of some processing/conversion, but how representative is that of the resources at disposal of the typical person in Ukraine? I imagine more urban residences with electricity and not a lot of cows.
    • glenstein 50 minutes ago
      You're comparing diesel to PV which doesn't speak to the merits of PV vs centralization. There's also the massive disadvantage of fuel distribution from diesel, which is a form of centralization and bottlenecking, and then there's fuel shortages and costs which PV doesn't have to bother with.

      Also is Russia targeting individual PV systems? That's tantamount to targeting individual residences which, if we're granting that, there's no amount of decentralizing that would ever mitigate those attacks so diesel vs PV would be moot.

      Lastly I don't think that's what greenwashing means. Greenwashing isn't representing renewables favorably, it's tying some external negative practice to language of environmentalism with vague buzzwords and questionable claims of environmental benefits to make that thing look better. But in this case there's no external thing being tied to environmentalism, we're just talking about PV directly.

    • juntoalaluna 53 minutes ago
      decentralising your fuel production and to a lesser extent distribution is not easy either though.

      > But can't energy from fossil fuels be generated in a decentralized manner too?

      How would that possibly work? Everyone has their own oil well and refinery? Their own fuel depots?

      And even if you were able to build all that, we would basically have giant bombs waiting to be ignited all over residential neighborhoods during war time...

      I would invite you to think through the logistics of what you propose before you launch into multiple paragraphs that assume those logistics are solved.

      • gnull 28 minutes ago
        I meant a diesel generator in a residential building. The refineries stay centralized somewhere safe (not a problem in Ukraine's case).
        • thelastgallon 15 minutes ago
          Do you mean a generator that creates diesel from bullshit[1]? Or a diesel generator that generates electricity?

          If its the latter, how is your idea decentralized fossil fuel? You are using the same fossil fuel supply chain as it exists today.

          For decentralized, you need an oil well in your backyard, and a refinery. THEN a diesel generator, if you want electricity.

          [1] Assuming you have enough cows

        • vrganj 17 minutes ago
          Then you don't solve the core problem of having a big juicy single point of failure. One that is very flammable at that, as Ukraine has proven in Russia recently.
    • streetfighter64 46 minutes ago
      That's not what greenwashing means. Greenwashing refers to marketing that sells a product as environmentally beneficial, while it's not in reality.

      Your claim is that they're selling a product (renewables) as beneficial for the war, while it's not. If I were to invent a term for that, it might be "camo-washing".

      Whether your argument makes sense or not, I don't know. But you fail to note the drawback of a diesel generator: it needs diesel, and thus logistics.

      • gnull 30 minutes ago
        I meant greenwashing as pulling a reason to make something about renewables out of thin air. In this case article's choice to center it's argument on renewables is greenwashing. Maybe I need a different word, not sure.

        The argument that decentralization (diesel or renewable) helps makes sense to me. What they do though is attribute the benefits of decentralized to renewables (ignoring how many buildings are powered by diesel in Ukraine today, those which did not receive that grant from Denmark to do solar), then completely skip potential downsides of renewables, and draw a conclusion from there.
