    Fossil fuel supply chain makes your country very vulnerable!

    <a href="https:&#x2F;&#x2F;github.com&#x2F;Lkruitwagen&#x2F;global-fossil-fuel-supply-chain" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Lkruitwagen&#x2F;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 (--&gt; 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.

      Both countries invested in nukes (it is claimed). Only Iran didn&#x27;t get there in time, before the US stepped in to stop them (it is claimed). So unless the US lets you, it&#x27;s probably a bad idea to invest in nukes, no? Or is your point that the US&#x27;s nuke story was a lie, and that Iran actually should have invested in nukes?

      &gt; 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&#x27;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.

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

        Sure, but you don&#x27;t have inexhaustible source of crude oil and a refinery in your backyard!

        But Sun reliably shows up most days. It doesn&#x27;t ghost. Sunlight can&#x27;t be sanctioned, tariffed, taxed, embargoed, pirated, nuked, rebuked, rebuffed, offended. Sunlight is also compatible with most religious beliefs (god is light, etc).

          Funny thing is, fuel can be transported, so that&#x27;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&#x27;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&#x27;t grow on trees.

          I&#x27;m sure we&#x27;ll see a transition to electric some day, it is more efficient purely from a physics standpoint. But I&#x27;d be shocked to see the military transition before civilian industry.

            You only need solar panels once. They do not need fueling, refueling, lubricants, anything at all.

            Solar panels have 25 year warranty. Can you think of anything that you have bought or can buy with a 25 year warranty?

            At the end of 25 years, they will produce 92%. Perfectly acceptable for a few more decades. The latest panels produce 740 - 800W+&#x2F;panel, this is sufficient for a lifetime without ever having to think of upgrades.
