We all know that the list of crises most survivalists plan for – and with good reason – usually includes the threat of an EMP attack. Whether it be from a nuclear explosion, solar flare, or some sort of specialized weapon, they have the capability to knock out the electrical grid. Thereby, leaving society without power for weeks, months, or even longer. Immediately coming to mind is the short lived Warner Brothers show called “Revolution”.
But with so much information and misinformation floating around about EMPs, it can be hard to know what is fact and what is fiction. This is why I would like to debunk some common EMP myths to help cipher fact from fiction when SHTF.
An EMP Will Fry Everything Electric
What is likely the biggest myth involving EMPs is that they will instantly destroy everything that has an electric current, leaving nothing functional. While it is true that an EMP can damage electronics, especially those which are plugged into the grid or are otherwise not shielded, it won’t necessarily take out everything. The small electronics not plugged into the grid, like a handheld radio, a flashlight, or select models of cars, can survive according to the pulse and shielding.

Truthfully, the damage that will happen from an EMP is unpredictable, and while one should be prepared for widespread power outages, it’s not guaranteed all electronics would instantly be destroyed. In fact, the wise thing to do is to have some critical devices shielded, such as communications or medical equipment, but don’t think everything electronic in nature will become permanently useless.
A Car EMP Attack Will Stop All Vehicles
You might have seen a movie where an EMP goes off and right away, every car in the road just stops working. This is an exaggeration. Although it is true that high level electronics, particularly those newer model cars, are more susceptible to EMP damage, many vehicles would still run after an EMP event, especially older ones. Cars from the 1980s or earlier, not reliant upon heavy electronic components, would likely survive an EMP.
Even some newer model cars would still run, depending on factors such as the strength of the EMP and what position the vehicle was in when hit. It does make sense to have an older model vehicle in preparation for EMPs, but not all hope is lost for those with newer models. It just isn’t as cut-and-dried as it seems portrayed in Hollywood.
You Can Cover Your Entire House with a Faraday Cage
Faraday cages are great at offering shielding against an EMP for a few select electronics, but they are not a universal remedy. You really can’t make your entire house into one big Faraday cage. I guess you could if you had the resources, time, and lack of concern for aesthetics. A smarter move is to focus on protecting the essentials – the smaller devices that keep you alive and connected, like radios, solar chargers, and medical gear.
In this case, the EMP Cloth comes in handy.
But keep in mind that this is not your average tinfoil trick or makeshift Faraday cage. In fact, it’s a specialized, military-grade material, notoriously difficult and costly to produce, that blocks every form of electromagnetic wave.
At 15 feet long and 3.5 feet wide, it’s built to cover practically any generator, be it diesel, gasoline, propane, or solar. And the best part? You don’t need tools or technical know-how. THIS VIDEO will show just how simple it is to wrap your generator in minutes with no wires, no grounding and no fuss.
A Solar Flare is the Same as a Nuclear EMP
A solar flare, such as the one that created the famous, or more appropriately infamous, Carrington Event in 1859 did cause an uncompromising geomagnetic storm that disrupted electrical systems.
However, that is not the same thing as a nuclear EMP. As most experienced preppers know, nuclear EMP is much stronger and radiates three different pulses: E1, E2, and E3. Each of those pulses does something different to systems, but the E1 pulse is most destructive to electronics. A solar flare, in turn, is best imitated by the E3 pulse, which really only affects long-distance electrical infrastructure-power lines and transformers.
In short, solar flares can indeed generate widespread power blackouts, but they are not nearly as destructive to smaller electronics as a nuclear EMP would be. Preparation against both sources of electromagnetic pulse is important but remember that they are different threats altogether.
Nothing Can Be Done to Get Ready for an EMP
Most people seem to believe an EMP is so disastrous and unforeseeable that nothing can be done to prepare for it. Nothing could be farther from the truth.
While it is impossible to say exactly when and how an EMP would occur, there are many things one can do in order to maximize your chances of survival when SHTF. For instance, you can start by learning the way our ancestors lived when they wouldn’t rely on electricity and other modern facilities.
If you wonder where to start, The Lost Ways II is that kind of book that will teach you anything you need to know, from how to preserve food without refrigeration, build hidden shelters, make natural medicines from common plants, and purify water using methods that don’t depend on modern tools.
An EMP Will Cause Immediate, Irreversible Chaos
Few people think that the instant an EMP strikes, we will see an immediate collapse into chaos as society at large is suddenly plunged into an irreversible world of post-apocalyptic nothingness. While an EMP would surely cause major disruptions, the aftermath would not necessarily be instant chaos. First, the scale of the impact would depend on how strong the EMP is and what region it hits. Second, many areas would immediately begin efforts to recover, apportioning resources to restore power and essential services.

Yes, things would be tough, and one should definitely prepare for a long period without electricity, but it’s not likely that overnight civilization would end. Communities would still organize, people would find ways to survive, and eventually, power would be restored in many areas. Keeping a level head and being part of a supportive community would go a long way in managing the aftermath.
Final Thoughts
Electromagnetic pulses, whether from a nuclear device or a natural event, form a very valid concern for the prepper. However, one should not allow all the myths surrounding EMPs to cloud their better judgment. An EMP might indeed cause serious disruptions, but the situation isn’t as hopeless as often painted on the big screen of Hollywood.

If there is no warning of an EMP, how can you get everything wrapped before damage takes place.
Keep your supplies wrapped. You don’t use you generator daily..
Its amazing only around 150 years ago there was no electrical devices. It’s hard to believe the grid all over the world could go down .But short term shtf involving electricity happens all the time .EMP was one of my main concerns as a prepper starting to studying the survivability of a nuclear war .This article helps take the doom fear out of the nuclear instant death scenario.Keep prepping…Watch out for the winter storms coming up.
Outer Spice – Well stated that “electrical issue” happen all the time! The concept of enjoy life and the luxuries of 2025 but be comfortable resetting to 1955 or 1920 when (not if) needed. Back that plan up by having the skills / practice to live as 1880 if forced to! That is a plan that covers a lot of possibilities!
We will be focused on growing food, gathering firewood and site security. If the aftermath of an EMP is absolutely crippling, a neighborhood meeting should be one of the first things to take place. Discuss all ideas going foreword with cooperation.
Absolutely! Getting everyone together early builds unity and makes planning so much easier. It’s the best way to stay organized and look out for one another.
Good article. The big take away from the “gained knowledge” since the 1970s is solar storms are different from EMP detonations. Solar Storms are rough on the whole electrical grid but much less impactful on individual electronic and vehicles. Sacrificial surge protectors and good grounding on incoming AC service for solar storms and lightning! An EMPs damage will vary based on size and location. A single EMP may affect a large city or region but even within that circumference the effects on individual electronics or vehicle (distance, angle, line of sight, etc) will be varied. Is the world in 2025 fully protected, no but the world is better than it was in 1980s, and better than it was in 1990s. Industries now test and consider EMP and Solar Storms in design and planning. The big problem as of 2025 for both EMPs and Solar Storms is “replacing all the transformers on the electrical grid” in a timely manner. Expect three to four years minimum in non-government, non-critical locations.
Hillbilly, your description of what could happen is one I agree with. I can live without small electronics but the overhead lines acting as an antenna that collects too much of a pulse for the transformers to handle may well be our undoing. Then there is no refrigeration for us as individuals or the supermarkets (or the whole supply chain) and all of the just in time scheduled delivery of our food becomes a big problem. This whole thing of small towns with fields raising food a short distance away has now changed to cities, suburbs, and sprawling growth that requires food from other states or other countries. This is the situation we have put ourselves into that concerns me the most. As a group we preppers are probably versatill, adaptable, and problem solvers enough for what comes our way but the reality is that if the grid is down for very long some people out there will starve to death.
Domeliving – Well stated by you that any disruptive event (natural or man-made) those living in dense population areas with high volume long distance supply logistic systems and on government assistance will suffer the most. A regional even will look much like Hurricane Katrina, a few weeks of major suffering followed by band-aids (red cross) and then relocation of the masses affected. As a prepper you want to avoid being the spot the government decides to relocate the masses to. A knowledge point for preppers to retain is past behavior by the government is to relocate those masses to other medium to large urban areas just outside the affected area. This is typical because of existing government infrastructure (building, offices, services) and efficient travel routes (highways, trains, bus routes, airlines) to those locations. Secondary relocation locations tend to be government controlled open spaces such as military bases, reserves, undeveloped property due to less paperwork (permits, approvals, local resistance).
Lome locations will benefit form quicker electrical restoration even if they are not on the priority list. Example would be a town that is adjacent to a hydroelectric dam, wind farm or power plant (coal or nuclear). Yes the Federal government will have everyone focused on the priority government installations and major cities but the local operators, technicians and linemen will ensure the town their families are living in while they run the dams and plants have power (even working on the side and in secret) no matter what the Federal government directs. Just human nature.
With an EMP cloth wrapped generator, does the generator need to be wrapped underneath/on the ground? Same with vehicles? Does the EMP penetrate up from the ground?
You need to wrap it underneath too, yes!
I typically ground my truck when not driving. Will this protect my pickup?
Bruce Latham – That is great question to start a big argument! LOL. Two theories at play, make a deliberate path to ground or leave as a high resistance isolated object to deter energy absorbance. Stating a baseline for general information to my knowledge EMP exposure testing is typically done on vehicles “as normal” so no extra grounding connection to earth. Now the argument part, starting with grounding the vehicle when parked or even dragging a conductor when driving. If the ground connection to earth is good (a big if) then the theory is the vehicle shell becomes its own Faraday cage assuming the shell of the vehicle (exposed or hidden) is metal and encompassing. In modern cars there are large open areas only covered by plastic or glass (full length sun roofs, fiberglass hoods, plastic pumper covers. etc). So grounding the vehicle to earth is questionable for effectiveness. The other theory is similar to airplanes getting struck by lightning while flying or cars with a downed power line on them. Because the is no strong path (low resistance path) to ground the energy tends to stay on the outer shell of the aircraft or car; jumping off asap to find a way to ground. Inside the airplane or car there is very little energy movement (surge) which is what does damage because there is no path to earth on the inside (default Isolated ground plane design). If you add a ground path to the car it basically becomes a lighting rod; “Hey surge I have a great path to earth so come to me”. My opinion – Do not add extra grounding conduction (earth connection) to any transport vehicle (on tires). Exception would be a large generator on a trailer that is parked and connected for use powering structures or tools, then ground to earth per the generator manufactures recommendations. I think you opened up a topic for a whole new article!
Self reply – I need an edit button for my posts so when I type fast and the wrong spelling is an actual word which spell check misses. Above “pumper” should have been bumper. I am a better welder than typist!
;-D
the elec grid is, tenuous, I am told. IF, thats a big IF a large area crashes, it can cause other areas to crash as they try to pick up load they can NOT handle. IF the problem is big enough we all go dark. Problem is, it takes good stable electric to be able to put areas back into Action. In todays world, they dont carry many transformers in stock, The back order line is long. If they need a hundred transformers to solve a problem, we have a giant problem. If 6 substations fail, its a bigger problem. Puch your baby kissing sucker stealing elected officials to address the GRid problems, protection from EMP’s of ALL sources, and the foolish lack of spare components. ( the entire just in time system is foolish ).
One commenter said if we are not warned, well if its not already protected, its too late.
How bad, well, sears told us they made 100 yr paint, laboratory tested, well those artificial lab tests for length of protection, well they dont use real calendars, so unless someone has set off a MASSIVE EMP, then we just dont know, for sure.
Faraday cage, ahead of time, good place for a tablet, lap top etc, a SPARE, loaded with what you want, after, is the best way to shield electronics.
Exactly! The grid’s more fragile than most think. If a big section fails, it can snowball fast. Without spare parts or stable power to restart, recovery could take a long time. Best move is to prepare ahead and protect what you can.
The second part of that equation is “fast”. In past cascading events (what you are referencing) the event occurred, demand spiked to fill the void, and the chain reaction failures occurred faster than humans could intervene to disconnect / isolate the affected areas (triage) and save the remaining grid. Very much like a solar storm surge but pulling (power demand) instead of pushing (power surge). One thing that A.I. may be of benefit for everyone is to exponentially improve the reaction time to that type of failure scenario. The other side of that argument is you have to give the AI control system the leeway to isolate (triage) areas of service for the greater good. I imagine the 1-800-who-can-I-sue lawyers will have a field day if that ever occurs. Prepper rule – Every decision is a two edged sword, consider both sides!
I was wondering…..like always….would communication be the number one priority on your EMP list of things to wrap up ? For cheap starters…some transistor radios and batteries? I think FEMA has some kind of national emergency broadcasting system hidden deep in a EPM proof bunker somewhere that could at least let the surviving citizens of the U.S.get a heads up on whats going on .
Outer Spice – A logic exercise. You want to prepare to have communications available after an event. So what type of communications do you intent to use or think will be beneficial?Starting with a hand crank AM/FM/weather/ EBS transistor radio to hear the Government Emergency Broadcasts. What is the benefit? You may get some generic music to listen to why resting from your chores. You may get directions to go to a FEMA location that you will ignore. You may get news reports of the overall impact and effected areas, a good thing if you think you can trust the information as true. Is it worth the prepping effort for the cost? Probably; I considered it a freebee prep, low cost and low effort. Local area communications with family and neighbors is probably a highly desirable item. That would be CB radios, scanners, and walkies talkies.You will get much more accurate information affecting your region by listening to a scanner than to any “official” media broadcasts Medium effort and medium cost. I consider this a must do! The monies are well spent and the effort to setup common channel uses with neighbors are important. Ham radio / satellite communications means very long distance communications. Is it a real benefit to know what is occurring 2000 or 3000 miles away? Do you want to know what is occurring, probably, but the cost is high and the effort is high (license, equipment, tower, spares) so unless you really enjoy the hobby aspects (a everyday hobby for you in a normal world) it will likely have a lower priority on your prepping list. A root cellar, alternative fuel heating system, alternative water supply system maybe a higher priority use of those monies and effort.
Ozark Hillbilly ….Yes there is something in side of me that would like to know the real truth and reason for a grid down scenario that i may be in as soon as possible.And not two years later….any way we may never know for sure…but i would think i could make better use of my time trying to survive ….if i knew right away the cause and scope of the event . Getting as much intelligence as possible including the neighbors and passers-by. And god forbid…..FEMA .
Oh….Due to the lack of funding parts of FEMA may not be functional at this time…Way to go Demacrats….Pull your heads out of your a** and vote to keep the Government running….Your a pain in the a** And a worthless party .
I have had lots and lots of e- mail from (ask a prepper) and I have downloaded to my bookmarks a lot of great recipes and ideas for how to’s , for just these situations. if I have this in a tablet (just say, and made it safe)…would I be able to get to these if the grid went down and there was no internet or wi- fi ?? in other words, would these bookmarks be accessible, can they be brought forward without the internet being available…thanx in advance for an answer
Simple answer – no. Anything on the web (bookmarks) or cloud is effected by power and connectivity issues,
Shelter(and clothing appropriate for the climate), then water, then food, then cooking and food preservation are top of the list. Worry about a radio is down about number ten on my list. But, thanks for your thoughts.
I agree with you ….but i was trying to address the issue of what electrical devices i would like to have covered first in the event of a EMP pulse on a late summers eve .Near Seattle WA.uhmmm..Electric prod…?….on second though…a taser and a walkman…☮
