I was having this conversation with my daughter and thought it was an interesting topic.

If an EMP or solar flare took out everything electronic in the whole world (permanently), how long do you think it would take for you to die, given your current location and circumstances.

I believe my daughter thinks we would live a lot longer than I do, but she is thinking about how long she can live without the internet while I am thinking the world will quickly descend into anarchy.

With no traditional forms of transport, so supplies would dry up, limited resources, health etc, law and order would be a challenge as things become more desperate.

I think I would live for about 3 months. I would try to get the family somewhere safe and remote and come back later, but I think most people would have the same idea.

    I think the immediate deaths would all be from people who need electricity to run medical devices.

    Followed shortly by people who require refrigerated medication.

    Followed by elderly who die from exposure to extreme, unconditioned temperatures.

    and that would be in the first, oh, say… week or two.

    Then, with fridges full of rotted food, your first major death wave will occur as masses of people lose their absolute goddamn minds in panic and fear and start food riots/try to rob from others/raid big industrial farms/neighborhood gardens/etc, which leads to mass deaths from starvation, exposure, exertion, desperation, and gunshot.

    Which will even out after about a week or two.

    Then you settle in for the slow burn. 3 months out you’ll have another, comparatively small wave of deaths from people who run out of non-refridgeration requiring medications.

    Then another slow burn until manufactured canned goods run out in stores and scavanged homes until a wave of starvation.

    All in all, I’d say you’d probably be over the bulk of the mass deaths after 6 months, and with a significantly reduced population… Which will be to the benefit of the survivors, since less people per mile will make farming/hunting easier, and life safer… because while raiders/thieves will always be a overarching concern and safety issue, at this point, most of the desperation should have passed along with most of the desperate.

    There will also be, for at least a generation, possibly two, the lingering unspoken understanding that more people than anyone would ever care to count only survived the famines and fall by eating the long pig.

      You forgot water in your scenario.

      To be fair most people in a first world country don’t need to think about water since it’s just “there”, all the time.

      But as soon as the electricity goes out the water supply goes out too.

      No water supply means no water to drink, with no water the human body die within 3 days, so people will start to rely on any dirty water they can find.

      About dirty water, no water also means no WC. I repeat: no WC so no evacuation of feces and urine. Within a few day a big city swill be covered with human excrement. Mixed with no clean water access it means that deadly waterborne diseases will spread extremely quickly.

        I wonder about the population using non-refrigerated but still vital medication being “comparatively small.” There are countless people who would no longer be getting things they need to live, and only a very small percentage of those folks would have the ability to grow a plant or something and refine themselves a substitute of some kind. I am really curious how those numbers would line up.

      Yep. I’d have about a month and a half of insulin to use, since it lasts that long out of refrigeration. It would take a while to actually kill me probably, but yeah that would be what gets me I think.

      You got it right. If you’re already in a hospital you’re screwed. Anyone on a ventilator etc. is dead in hours.Then there’s people who need special meds that require refrigeration. They’re dead in days. Depending on the season, many more are dead in weeks. Food would be an issue but there are lots of shelf stable/canned goods that could last for a bit. Scarcity would be the bigger concern.

      The dead bodies themselves could also be an issue at scale.

      The crazier issue in my mind are all the industrial plants, nuclear power plants, chemical processing facilities…

      In any major catastrophe they are abandoned and likely the meltdown and other issues could render whole areas uninhabitable. Might be manageable in certain power loss scenarios… but anything major and sudden like if you’re country suffered a nuclear attack or a major natural catastrophe and you survived I’d stay away from nuclear plants or chemical processing facilities. Potable water will be hard enough to come by…

    There is a book that describes exactly that: Ashes, Ashes by Barjavel.

    It’s a classic of French science-fiction literature and I recommended everyone to read.

    It was written in 1943, it describes a parisian dystopian society in 2050 where all the electricity suddenly stop overnight. Even thought the book is 80 years old it is surprisingly accurate in some aspect.

    Hard to say.

    The biggest challenge would be to get out of the city and make the trip to my family’s farm safely. It would take about a week on foot/bikes using less known roads with all the supplies/weapons that would be crucial.

    If I could get to the farm, rest would be fairly easy. I can farm, fish and and hunt. Heating works with wood. Fresh water is not a problem, nor is refrigeration with an ice cellar. My family has an old mill that we could restore to get flour and I think I could retrofit it to produce hydroelectricity in a year or so.

    I’d trade access to electricity to get horses and other farm animals.

    Almost every neighbour is related to me, so forming a defensive alliance should be possible.

    I have the gear and the knowhow to make things work, it’s the not-getting-killed part at the start that’s hard.

      The trouble isn’t that you can’t do all that. It’s how many other people have that same idea. Rural areas will be overrun by people who think getting out of the cities is the best idea – not that they’re wrong – but it will run supplies low outside cities too, and home gardens and the local deer population can only take so much pressure. That’s not even to mention the road traffic. If cities can’t handle rush hour, 2 lanes will certainly be gridlocked as everyone looks for the next road not taken. The locals would not take kindly to such an influx either.

      The best strategy in my mind would be to stockpile food and other necessities wherever you are now and prepare for a long wait, hoping power gets restored. It would be horrible and dangerous no matter where.

      3 months is when my insulin runs out. I doubt I’d make it that long in the USA.

        Like I said, the start would be the hardest part. Cars or any other motor vehicles would be out of the question.

        f this scenario would happen during the winter, it would effectively block all the lesser known forest roads for vehicle use. Doing the trip with skis would easily halve my travel time, even with the supply sled and heavy backpacks. 30-50km per day would be easy, when one wouldn’t have to go around all the lakes and rivers. We don’t get much daylight here in the far north so travelling in the cover of darkness would be ideal. I can find my way in dark forests with ease.

        In the summer, the trip would be much more problematic. My country has countless number of old, unmarked roads and forest paths that are usually suitable for mountain bikes. This would be my first option. The second would be crossing the forests by foot which would be very safe, but it would take time.

        My relatives would take care of the farm until I would arrive, of that I am certain - and they are very capable of doing so. My family has stuck around those parts for hundreds of years and we aim to keep it that way in any scenario ;)

      I don’t know how well I would do even if I escaped to my inlaws farm. It is pretty low tech but they are depending on city water which involves pumps and a moped to even get to the farm from their house still requires a battery.

    Way longer than your average person but I’d start running out of supplies after few months too. I have food stocked up for few months, 90 litres of drinking water and a water filter, 120 litres of diesel plus what I have in the tank, enough fuel to run alchohol stove for few months aswell and I have a fireplace to keep myself warm basically indefinitely.

    It’s kind of scary to think that even me whose somewhat of a prepper would run out of supplies quite quick. What does that mean for the average person who doesn’t even have a jug of water stored up.

    Also, this is the kind of discussion that would fit well on !zombiesurvival@sopuli.xyz

        I mostly stock up on items I’m using anyways such as rice, beans, noodles, sugar, coffee, crackers, honey, peanut butter etc. and I’m constantly using the oldest packages from my stock and replacing them with fresh ones.

    If given enough notice to store water and fill 3 good coolers with ice, longer than 2 weeks - we lost power for 2 weeks with a hurricane once and had an electric well pump so no water either. Had set up a system with one cooler allowed to be opened, the others not often. By 2 weeks the water that we’d filled the tub with (for washing not drinking - water with a little bit of bleach) was getting questionable.

    Like you, I think the biggest issue would be people.

      Same reason you’d want to live in this fucked up world full of injustice and suffering.

      Most people have a very powerful inherent drive to survive, and a lot of people who think they’ve got nothing to live for experience a reprioritization and will fight like hell to survive.

      Most individuals who try to kill themselves immediately regret their decision. This happens a lot with jumpers, where most survivors report immediately regretting the decision as soon as they are in free fall and their brains reprioritize survival over the petty or even significant reasons we had to jump in the first place.

      Just after jumping and while mid-air, Ken said, “I realized, at that moment, this is the stupidest thing I could have done.”

      “I instantly realized that everything in my life that I’d thought was unfixable was totally fixable — except for having just jumped.” Source

        Yeah yeah. Heard that story like a billion times. Totally agree. I’d rather die from starvation after having witnessed my loved ones die from similar circumstances. And I’m not being facetious. This is preferable to suicide.

            Nah. If Food runs out, food runs out. Evenly distributed rations. It’s simply more likely I’d survive longer as my general health is better than my loved ones right now, and therefore I would likely be the one to bear witness to their tragic demise.

            I can see why you’d think that though, based off of the unclear wording of my previous reply.

    There’s a fantastic book series based on exactly this: The Change Series. This is a double storyline with the Emberverse series in which the present time beginning in March 1998 loses electricity and “most forms of high-energy-density technology” due to “The Change”, which occurs at 6:15 p.m. Pacific Standard Time, March 17, 1998.

    The companion series, which was written first, is the Nantucket Series, in which the island of Nantucket is transported back in time to 1250 BC due to something called “The Event”, the same Event that caused The Change. But— they got to keep all their physics intact.

    If property rights are still enforced in the turmoil probably indefinitely. Doesn’t mean I’d enjoy it, though.

    I come from a place where survival agriculture was the norm well into the 1980s. Would have to start having cows and pigs again, need to work out a salting station, which we haven’t had for a few decades. I remember soap making was a mess. We got rid of our wood-fueled kitchen at some point, so that’s a problem until society settles back in enough to start selling those again. We’d probably have to go back to setting up a corner for a fireplace in the meantime. That’s before my time but it should be possible.

    This question reminded me of the Dr Stone anime. The premise is that a wave turns everyone into marble, several thousands years later a young scientist is unfrozen and uses science to restore society to its former state.

    Also, I wonder what the effects of long term exposure to EMP would be to life on earth. Since most neurological systems use electromagnetic waves maybe they are impacted?

    Another interesting question would be if there would be a way to work around the EMP. For example, would a Faraday cage work to allow electronics to work inside it? Or maybe electronics are improved to work under the effect of EMP? Like how the CPUs have bit correction algorithms because of random bit flips that occur due to solar flares.

    Last but not least, in such a situation my plan would be to go as far away as possible, since there will be food shortages, being in an area where you can forage for food or hunt animals would be a priority. Then, I would probably die eating something poisonous. If I survive long enough to set up a farm, I would probably survive the next 10 years or so until I die of old age at 35 the new average life expectancy.

    I have a bike and know how to repair it, so if there are materials availiable in case of an emergency, I would have a means of transport that doesn’t rely on electricity or gas. I’m a bit out of shape ATM but that’s a problem that would fix itself if I “had to” rely on a bike to get around.

    I know how to build fires, chop and dry wood, sharpen an axe properly and there are lots of trees around these parts, so with a little extra work I would be able to stay warm and cook food. I think I even still have my grandpa’s old axe here somewhere.

    My grandparents taught me how to preserve stuff properly; drying, pickling, smoking and canning raw foods, like fruit, veggies, fish, meat and mushrooms. I know how to grow and store potatoes properly - the only thing I’d need here would be a bit of fertile land and a cellar, but in case of a world wide disaster like that, it would probably not be that hard to find people willing to turn their lawn into a field and toss out obsolete electronics out of their cellar to store food there instead.

    I know how to fish and I’m not that bad with a bow either (medieval enthusiast here), and I know how to quickly kill and properly prepare chickens, ducks and rabbits. No actual experience with bigger animals yet, but the basics are there and I’m not icky about getting my hands dirty. I know how to skin rabbits too, but I have not yet tried to make leather / pelts.

    I am somwehat okay at identifying wild mushrooms, but not good enough to be 100% certain all the time, so that’s a point where I needed to be cautious.

    There are plenty of small rivers around these parts, so drinking water might not be an issue, provided that stuff is actually safe to drink. Boiling doesn’t always remove all the nasty stuff, and I only have a very vague idea of how to build filters out of natural materials, so I would either need to experiment around, rely on the knowledge of others, or look it up on the then nonexistent internet.

    I would definitely miss the internet and since I’m a total videogame nerd as well, it would suck big time to lose that hobby permanently, but as for sheer survival, I’m fairly certain I would make it for a while, especially if I could find other people to teach them what I know and build a small community. I can’t do ALL of the things mentioned above all on my own every single day for weeks or months on end, but if the knowledge is there and there are people willing to learn and do their share, I’m positive it would work out after a while.

    The biggest issues would probably be medicine and other people: My knowledge about natural medicine is VERY limited - birch bark for pain and the like, but I wouldn’t be able to treat more serious injuries or diseases properly on my own. And since people as a whole tend to be assholes when presented with disastrous conditions, I would be very cautious about whom to trust. A lot of doomsday preppers seem to have the only plan of hoarding weapons and food and shooting others when running low on supplies so they can take other people’s stuff, and that’s nothing I would want to have to deal with.

    PS: Just to mention it; I live in a somewhat rural area anyway. Plenty of people here still keep their own chickens, live in houses that still have wood stoves and “old timey” fireplaces, grow their own veggies and fruit, and I know at least two families around these parts that still have horse-drawn carriages and trained shirehorses (they offer rides for a fee for events, parties and the like). A lot of older folks here grew up on farms and have the respective knowledge still. We even have a “traditional” blacksmith and farrier here, as well as a hunting club with a couple dozen members. The knowledge of how to survive without elctricity is definitely there, a lot of non-electric tools as well, and everything else is just a matter of time and cooperation.

    Medicine would still be an issue tho. (Insulin has been mentoined a couple of times already - you can’t just substitute traditional natural folk medicine for everything)
