i believe the 2% figure is global agricultures total energy usage out of total global energy supply. the 5% is more specifically fertilizer from natural gas supply.
fertilizer prices have come back down again, but yeah any time price rises the cost rapidly prices out marginal producers and the consumers at the bottom of the socioeconomic ladder.
I know eurozone fertilizer production seems utterly fucked without access to the cheap russian gas. USA is booming with pipelines and new ammonia production facilities .
There has been a number of “we got this” claims for green nitrogen production that ive followed for some years and tried to get data from but every one of them has narrative to spew and zero math to give an idea of energy cost of per unit of N which lights up my bullshit meter. an example of a company https://jupiterionics.com/our-technology/ though i see they changed their website since last time i checked so maybe their is data now. The fact that none of them will give figures to compare makes me pretty sure they are all worse than Birkeland–Eyde process which is not dependent on fossil fuels in the same way as haber bosch process.
1 lb nitrogen per 43lbs dry corn grain, 1lb nitrogen per 150lb potatoes production.
According to wikipedia With 1kwh in birkland eyde process you get about 60grams of Nitric acid so ?13.333? of elemental N (if i did the chemistry conversions right).
So a 1kwh solar array in oregon would get about 5kwh per day in the spring ramping up to 7.5kwh in summer which happens to track plant N needs since its light dependent . so if we just use a 6kwh average for may-september growing season we get 900kwh x 13 = 11700g = 11.7 kilos elemental N which is 25.13 kilos urea or 33.4 kilos ammonium nitrate (check my chemistry)
Bringing us (sorry switching back to lbs instead of kilos again) a solid 25lbs of N which is good for about 1075lb of corn grain or 3750lb of potato which is adequate for a single persons yearly calorie rations.
So overall i think it could make economic sense as a survival enhancement to get a cheap 1kw used solar panel array connected to a home brew Birkeland–Eyde nitric acid generator bubbling through a limestone/dolomite pea gravel bubble barrel (calcium nitrate) fed to a mazzei injector to fertigate a home self sufficiency garden.
Thoughts anyone?
amortized across 25+ years in food value versus retail it pays for itself many time over . costs versus just buying 1 ton pallet of 20 kilo bags of fertilizer , maybe not as advantageous economically but certainly a cooler project than explaining why you have an entire ton of ammonium nitrate in the shed
“I wish I had the money it would take to garden my yard properly”
What requires money? , just take seeds and cuttings of anything you buy at the store to eat and plant them. a bag of lime and fertilizer will pay itself back x100. If you have a yard you are already 99.9% there just get a shovel. You could have the thing running full speed by spring
I’m open to suggestions. A lot of it will just be people i’ve known for long enough to know their quirks and dependability so i can get things started like that.
From what ive seen with communities that have any longevity they seem to converge upon similar process.
1.some type of contact like phone call/email/application figuring out if they seem sane and functional enough to have that basic interaction . this screens out some nuts and gets info for criminal background checks to make sure not convicted sex offenders or habitually violent danger.

visitation period usually under 2 weeks stay , part of this is because laws about short term stays mean you can kick them out whereas longer stays can require legal eviction even if there is no contract or rent exchanged legally you establish residence. So interact with them for the 2 weeks and have them automatically required to leave the property. evaluation by everyone in the community come to consensus for longer stay probationary period . This stage weeds out the impulsive perverts, drug addicts, alcoholics and some worse off mentally ill
-
probationary period These can be from 6 months to 2 years. Get consensus for full membership. This weeds out more of the adept cluster B personality disorders and removed free riders
Because there is so much convergence on that pattern i will just assume it is the best construct.
as for what the actual selection criteria are ,thats a whole other can of worms.
Im looking mostly in oregon. the plan is set up co-op situation mixture of community and personal land bulk buy for lower price per acre. west coast is mostly overpriced though on a per unit of bioproductivity basis so still considering other spots. underground weed economy crash is bringing lots of cheap per acre properties on market though
yeah i downloaded my reddit history. there are still reddit archives run by third parties that save everything indexed to usernames i think , you might be able to search the old stuff like that.
I will try to sort through all my reddit crap at some point and maybe post stuff thats useful as blog or publish a magazine or something. Im trying to exit the internet 95% over the next 2 years and get my anti-doomsday cult going fully in real life.
internet is such a shitshow that i realized its mostly just a negative in every way now. i dont know what its good for at this point.
At this point i would just prefer interacting with people in more direct ways. im writing off everyone not in my future tribe of back to the land revolutionaries plotting the destruction of the status quo and birth of alternatives.
yeah but there is no consumption without population. Pop*consumption= environmental impact.
Talking about population doesn’t imply ignoring consumption as the best target for mitigating the problem. But the market will do that as prices rise and kick more population out of the “consumption is viable” cohort. unfortunately the market starts with the poorest and least consuming
