<a href="https://github.com/Lkruitwagen/global-fossil-fuel-supply-chain" rel="nofollow">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.

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...

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.

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 more land than that because the sun isnt directly overhead, plus winter/rainy days... it is a massive solar farm (and a massive battery) just to replace an average highway gas station.
Given that any future 2-lane highway might see a couple thousand thousand EVs each hour, each needing charging every couple hundred miles, the number and size of solar charging stations per mile is crazy.

You need to go to a gas station BECAUSE there is no supply of gasoline straight to home. Homes have electricity. Even in sub-Saharan Africa, South Sudan, Yemen, remotest village in India. I don't know where you live, but if your home doesn't have electricity, your country has bigger problems to deal with than buying Teslas and DC Fast Chargers.

I ran into that problem during covid. I had to do a few work-related 1000-mile drives and they had closed most all the restrooms!
And my home is also home to a few hundred other people. Installing enough chargers for all our cars would require a massive grid upgrade that our city would never support. Not everyone lives in a suburb.

Do you not have an ovens? Or electric shower? Mine use 7kW, same as the car charger.
