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.

      I hate when people try to brag that they’d easily survive the apocalypse cause they’ve prepped, or hoarded, or trained, or whatever. Like bitch if you’re in the first city to be bombed or patient zero, you dead.

          Perhaps I worded it poorly. I quoted you qualifying your success with the necessity for luck. I was applauding the affirmation that even with plenty of skills and preparedness, some things are out of our hands.

          No doubt there would be people that had no business surviving but make it on pure luck and the goodwill of others. Though luck favors the prepared.

    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.

    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.

    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’ve always wondered. Do you folks just chow on nothing but canned food ands military reasons for a few months straight every couple years when things expire? Or just donate?

      Don’t get me wrong. I think it’s good to have emergency supplies. But things expire…

        EMP would not affect devices that aren’t connected to the grid. Atleast I don’t think it would, and even if it did, there’s still plenty of older diesel powered machines that don’t need electricity to run such as some diesel heaters. If nothing else I could trade it for something more useful then.

          EMP affects all electronics as long as it’s in line of sight. With that said EMPs are not a very effective way to knock out power for the entire US.

          You’d have to launch nukes up into the sky and detonate them in the air in order for an EMP to be effective. You’d need to use several of them spread out across the US.

          The chances of that happening are super low unless it’s our own government doing it.

    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.

    Hopefully quite a while. I’m regularly in the wilderness, a holiday is 2-3 weeks off-grid. The only thing I use electricity for is lighting (torches and camp) and music/radio, powered off battery’s that are handled by solar.

    I aim to extend food by fishing, which usually is week 2 after my stored meat is gone and I need more protein. I have a couple of different weighted bows, but rarely hunt as it requires extra licensing. Lots and lots and lots of expedition-level outdoor/survival gear.

    Combine that all with still having a house for shelter, should be fine. Love a book and crosswords for non-electric entertainment, otherwise mountain biking or rock climbing. I won’t get bored.

      I think fish wouldnt be as available as you think, since tons of desperate people will use less than ethical means to harvest every edible, living thing from the river systems.

      Leaving to massive ecological damage, and possibly massive contamination as well.

              You are thinking like a fisherman, and not a throng of panicky, starving masses.

              I bet most the fish wont even be cooked before being consumed.

              Nor will care be given for any toxins dumped into the water to try and scoop every living organism out of it in the starved panic.

                  Assuming an intentional EMP sent America back to the stone age, then America would respond in kind to China, N.Korea, Iran, Pakistan and Russia. England, continental Europe, Turkey, India, Israel, Japan, S. Korea would all have been hit with the same at the same time. If somehow we all just traded queens and stopped there, or if a prolonged solar storm hit the planet repeatedly accomplishing the same, I really think your optimistic limiting global losses to 75%

                  After the first northern winter I would assume 90-95% of humanity is gone. Those that can hunt are the most likely to survive. Seafood increases your odds of survival by orders of magnitude, as it requires some skill, but much less caloric investment before reward. By and large we’ve lost the ability to farm without fertilizers and pesticides, many will try but one early freeze will kill off dependant communities. Climate change making weather less predictable def does not work in our favor.

                  After the first winter I wouldn’t be afraid of strangers. Another person is far too valuable, when you remember that there are lots of things outside that will happily kill us. We only have strength when we’re in numbers.

              Depends if you’re fishing off a river or ocean/lake. Could easily see goofs just throwing a net across an entire river.

              Even lakes, I wouldn’t be sure about in the long term. Every boomer with a fishing pole is probably headed to a lake if they can…

    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)

    I think the biggest issue would be food. We have loads of farmers in the area and the bike is usable. However, to many people in the area and a lot of specialized crop.

    With the canned food, I guess around a month, then it’ll get challeging.
