Simulation or physical reality being secondary, the question asked to be addressed has tremendous fallacies and baseless assumptions within it.

1 Urban farming is a solution. Within modern (as known) urban areas we can attain food autonomy by urban food production. BEEP: No it can’t. It will either have to sprawl out like US monstrosities of suburbia with a diameter of 50-100miles for 5million people, or it just can’t be achieved. Plain and simple, even with non-sustainable intensive monocultures you need at least an acre (o.4 hectares, 4k sq.m) for a family of 4 to produce barely adequate food to escape famine and malnutrition. Those joker pads of 100sq.m per family to produce vegies, in a triple cheesburger eating society, are just nasty jokes. Even this little of food production needs constant import of fertilization as 99% of what is eaten ends up on oceans and it is illegal to process as fertilizer. So again, an urban population without a mechanism of suppressing and exploiting rural populations to supply them with food can’t possibly exist.

2 Energy: An urban area can reach energy autonomy based on non-US, maybe European standards, rates of consumption (about 50% of US) with “green energy”. BEEP! No it can’t. Even if the entire urban area was to be covered by solar panels and wind-generators on top of them, and all people live under that panel with light only coming from the cracks between them, it still not enough. Only mildew can be grown in the dark. Add some mediocre ultra-expensive solutions of using tidal/swell energy for coastal towns, and making all beach look like an electric super-plant, still not enough. Plain and ef.ing simple. Just read the numbers, consumption, maximum possible production, efficiency, … not even close to be worth discussing it.

3 Waste recovery of raw materials can replace mining. No it can’t, at the levels of conditioning of people to keep replacing used goods with new at alarming rates, industrialized machines becoming less and less able to be repaired and maintained, no recycling can ever keep up and increases costs tremendously. Only the exploitation of refugees and desperate immigrants make some recycling possible and profitable currently to be sub-1% supplement to material consumption. It is very labor intensive and no automation has been devised to replace human critical ability. So BEEP BEEP again on assumptions.

4 Green energy: It is perceived and myth busted that organic substance can be used as an alternative fuel, bio-mass and the like. Think of the planet as a dry rock, of dead substance, sand rocks, etc. No life on it, then add an extremely thin crust of life (from microorganisms, to grass, trees, animals, whales, etc.). 100% of all those organisms eat living or recently deceased other lives to survive. A miracle of life among countless dead planets and moons. This total amount of organic substance, living or decomposing to provide food for more life, if burned, to the last gram of carbohydrate, can not produce enough energy to last humanity for a year. Even at imaginary levels of efficiency (energy transform heat - electric - mechanical). Then it will be a dessertified planet, without any life on it, or food for any humans to survive, let alone animals, plants, and microorganisms. So, again a myth, a fallacy passed by the oil industry itself, as oil and coal is heavily invested in this new party of environmental disaster called "green energy"™. And the nuclear industry is standing by laughing hard at the stupidity of it all, knowing they are the last true resort to an environmentally minded energy solution to capitalism going rogue.

Just the fact there is all this retooling in industry, replacing vehicles and machines from using fuel as energy to be using a much less efficient “electricity” (the dirtiest energy source there is) to be driven, multiplies profit and continuous industrial development and production for “the LITTLE TIME WE HAVE LEFT TO FUCK THE PLANET UP”. It has also multiplied mining by 7-10x of what it was 20y ago.

5. Politically: We have managed to be indoctrinated and passively conditioned like experimental monkeys, to think of “public land/sea/lake/river” as “state property” for which, the dear state thinking for us and deciding for us, for our own mutual benefit, to pass all public land and water to private interests, because of the “green energy” myth. This private land, whether the experiment backfires, it is both altered/destroyed by private exploitation and can’t be reverted to public use and access without a bloody revolution. So maybe this was the goal to begin with.

In violation of most constitutions and “common sense”, public land/water contained (in the distant past/history of 20th century) the “right” of access and use by humans, even foreigners in a country can visit and climb mountains, bathe in rivers, lakes, and sea, walk through forests (the last that existed). A human right revoked, single handedly, without a real political discourse on it, as ALL political parties agreed public property IS STATE PROPERTY! Now, it is handed over to private armies/security, to prohibit access as to protect the infrastructure for privately produced electricity, water, etc. from out ex-public land. Our land, our water, our wind, our sun, by-proxy “donated” to multinational energy and water cartels.

Because of Green Energy, humans can no longer seek food autonomy, or any other autonomy, without breaking “private property laws”, and therefore ANY ATTEMPT to autonomy is now ILLEGAL! No food no autonomy, no land no food.

10 We have gone a full circle from the times of feudalism to return being slaves again to multinational corporations, absolutely dependent on their game for minimal survival. The huge difference from feudalism (Chinese, Indian, European, doesn’t matter) is we are now in multiples more than we were, with an 80% destroyed land, incapable in recovering for thousands of years (what takes for a forest to recover and become yet again stable and sustainable).

In summary: We have no time to play games, the clock is ticking. The chains on our legs and arms are getting heavier, it is either now or never.

PS Watch planet of the humans, not propaganda about it/against it, and keep an open mind that it was not financed by petroleum/coal/nuclear/vehicle industries/

A few problems with that:

Cleaner(er) energy - making a power grid work with only renewables will be a huge challenge that I would love to see. Maybe there can be a limit for one nuclear power plant and bonus points if it’s a single reactor, that way there is baseline power but I think you must have your own waste facility.

1. The game uses only technology from the Eastern bloc up to around 1991, and hydro power plants are not included because of deeper engine limitations. What’s left is really not good enough for this.

2. The game, as far as I can see, still has major bugs with its electric grid simulation that surface when you connect any power plants via medium voltage. Wind power plants can only be connected via medium voltage, though. The only solution I’ve found is to never connect wind power plants to the grid and only ever to use them as a localized backup solution for infrastructure that is so critical it needs to continue working even when the grid has problems or infrastructure that is so uncritical, I cannot be bothered to run a powerline to it.

Solarpunk communism. I second the challenge. I would love to see some aesthetically pleasing urban farming.
