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.

No one will attack North Korea because they are backed by China. I'm not sure how nuclear weapons helps them unless they split from China. Maybe they make money selling the tech to others.

A defense pact doesn’t always hold, though. Poland had a mutual defense pact with France and the UK in September 1939. And even if China were to aide the DPRK in a crisis, the DPRK would be the junior partner in that arrangement. In this scenario, if China is providing the lions share of manpower and weapons, they get to decide strategy, and dictate terms for war termination.
The DPRKs primary goal is preservation of the Kim regime above all else. That’s why the DPRK over the last 70+ years has focused on Juche, a principle of self-reliance. The vast majority of their weapon systems are of indigenous designs and manufacture. And why they have developed and deployed an independent nuclear deterrent.

All terrain vehicles are sufficiently slow and visible that they're arguably more vulnerable in most cases.
In Ukraine electric buggies have been used for frontline mobility because they're quiet, the wheeled military vehicles are in demand because combined with even a dirt road they're a lot faster getting around - i.e. one feature of the HIMARS is that it's not tracked.

Nukes are arguably ONLY useful in defense (and deterring another from attacking). Using nuclear weapons against an opponent that also has nuclear weapons will very likely lead to a nuclear exchange and the decimation of both countries. It’s suicide, and so no one is going to do it unless they have nothing left to lose. A nation under attack, facing an existential threat, and about to be overrun, is in exactly that circumstance.
And yeah, maybe the defending countries leader isn’t willing to end it all, and maybe try collaboration or partisan resistance. But if you were the attacking country, would you be willing to make that bet? Or would you hesitate?

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.

I have done the math, several times. The last time was to plan 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 approaching square kilometers/miles in scale.
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.

Don't do the math for homeless people. Most people live in homes. Homes usually have electricity, unless you live in a 4th world country. All buildings have electricity. Just park and plug in.
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.

Highways. Highways need to support people traveling beyond the range of thier vehicles, be that a car or bus/truck. People could also eat and use the bathroom at home, but highways must still make space for restaurants and restrooms.
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.

Highways often have powerlines nearby at least every now and then. With those you can take power from roofs many kilometres away!
And what you say about apartments is wrong, it’s definitely not impossible.

I've done the math. The average car in Canada does 11,000 miles a year. A Tesla isn't great efficiency, it uses about 3.5 miles per kWh. Throw in inefficiency of charging and you're talking about 3MWh per car per year, and with about 25 million vehicles that means about 75TWh a year
Travers Solar in Alberta generates about 2.5TWh a year from under 14 sqkm.
Build 30 of them and that's 400 sqkm.
A 20sqkm by 20sqkm solar plant would power every car and light van in Canada forever (setting aside seasonality).
Factor in lower generation in December, you'd need 10 times that amount of solar, about 70km by 70km, 5000 square km.
That's less than 1 quarter of 1 percent of the land in Alberta alone.
(Of course you wouldn't put it in one location, it would be spread out across the country)
Funnily enough 5000 square km is about the total land use of Canada's oil land use (surface use)
You'd have a lot of excess power in the summer -- you'd be generating 650TWh of excess power a year

Or, convert the solar energy to heat, then back to electricity at 40% round trip efficiency. Needs only 2.5x the solar (or less, because some solar goes directly to the users without long term storage). The heat is very storable at scale, even for seasonal storage.

Lol, 11,000 is for all the city-bound teslas that only drive from suburb to the office. Actual average car use is closer to 25,000km/year (15,000 miles is the us average). But cars are not all road users. The "100 teslas/hour" standard is to accomidate trucks too.
If you are planning infrastructure like highways, national averages are irrelevant. It is the same debate that Hertz had when it dropped teslas: charging infrastructure is local and rental car locations (airports) cannot support the needed power density.

Home solar arrays are 10-100kw (order of magnitude).
EVs go 2-5 miles per kWh.
So, the charge rate is 20-500 miles per hour when the sun is out.
Assume one extra EV per house, round robin. New EVs are $10-60K, depending on county. The solar is, say, $30K.
So, $60-210K per house for ten years of energy independence for a two car ICE house. ICE cars wear out faster than EVs. You can figure gas, grid and inflated maintenance on the ICE route yourself, but the math works.
Of course, used EVs more than halve my estimates,

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.

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)

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+/panel, this is sufficient for a lifetime without ever having to think of upgrades.

That won't help you if you can't refine it. Russia has more oil than most and has/had lots of refineries. Ukraine has taken out so many of them that Trump is complaining it's affecting the price of diesel (even though the US also has lots of oil and lots of refineries).

Yes. All cars and vans in the UK drive a total of 320 billion miles a year. My own electric car tells me this would require 80 billion kWh. 1kWp produces 1000 kWh a year, so you need 80 million kWp or 80 TWh a year.
My house will easily provide 8kWp, meaning you'd need 10 million houses. There's 30 million homes, and that's before you factor in non-domestic buildings.
A single shooting estate in the uk could produce 20TWh a year with solar alone. Throw in wind and that would petty much double.
