9 Mind Bending Effects of a Grid Collapsing EMP

We have seen swaths of Americans without power and basics services for weeks. We have seen the worst from desperate people in these situations.

What we have never witnessed is a nation of 300 million or even a quarter of the nation, 75 million people, falling victim to a compromised electrical grid. Even a partial grid down scenario would, to some degree, affect the flow of information, services and resources all over the nation.

The best source of EMP knowledge available is a report created by a committee of brilliant men and women. They are called the Commission to Assess the Threat to the United States from Electromagnetic Pulse (EMP) Attack.

“Because of the ubiquitous dependence of U.S. society on the electrical power system, its vulnerability to an EMP attack, coupled with the EMP’s particular damage mechanisms, creates the possibility of long-term, catastrophic consequences. The implicit invitation to take advantage of this vulnerability, when coupled with increasing proliferation of nuclear weapons and their delivery systems, is a serious concern. A single EMP attack may seriously degrade or shut down a large part of the electric power grid in the geographic area of EMP exposure effectively instantaneously. There is also a possibility of functional collapse of grids beyond the exposed area, as electrical effects propagate from one region to another.”

Excerpt from the Report of the Commission to Assess the Threat to the United States from Electromagnetic Pulse (EMP) Attack.

We live and operate in a fully connected and dependent system. We will observe the many consequences of an EMP attack on our highly-integrated systems.

Banking and Finance

According to the President’s National Security Telecommunications Advisory Committee (NSTAC):

“The financial services industry has evolved to a point where it would be impossible to operate without the efficiencies of information technology and networks.”

There are trades happening electronically faster than we can even fathom. The scary thing about all of this is that we have created a system that can only go forward. There is no standing still or going back. Banks would go into panic mode and they would be hard pressed to give out any cash money. Cash on hand is not the strong suit of most Americans.

Petroleum and Natural Gas

Though we are dealing with natural substances born of the earth the systems in place to refine, hold and transport this energy would be affected. Just as we discussed in the section on infrastructure valves, shutoffs and other components would be rendered inoperable. The flow of energy will come to a standstill in the face of an EMP.

This powerful report describes telecommunications about as thoroughly as possible.

  • The mix of equipment used to initiate and receive voice, data, and video messages (e.g., cell phones and personal computers).
  • The associated media (e.g., fiber optics and copper) and equipment (e.g., multiplexers) that transport those messages.
  • The equipment that routes the messages between destinations (e.g., Internet Protocol [IP]-based routers).
  • The basic and enhanced services offered by communications carriers such as AT&T, Verizon Wireless, and Comcast.
  • The supporting monitoring and management systems that identify, mitigate, and repair problems that can impact performance of services.
  • The supporting administrative systems for functions such as billing.

This explanation helps you understand just how much of your own life would be effected. Now imagine a world that is inextricably tied by these services. The true effect of the EMP is not merely the loss of electricity but a punishing blow to these systems that all depend on one another.

Transportation Infrastructure

Whether we are talking about railroad, trucking, maritime or air travel each will be drastically affected by an EMP. The very GPS and satellite information that drives these modes of transportation could be compromised not to mention our discussion on the energies they need to be fueled.

Of course, without these heavy freight transports food and textile resources would no longer move either. By now you are probably starting to understand just how connected and dependent these systems are.

Water Infrastructure

Now the obvious challenge with water will be the machinery that skims and cleans it as well as the pumps that prevent backflow. I want to present a different concern to the ‘pool’ of issues.

The analysis of our water is done primarily by TOC (totally organic carbon) analyzers that measure pollutants and other disease causing pathogens. Without our ability to analyze the water we would have to create a common and consistent method of measuring water quality. This could result in hundreds of thousands of sick people if not done correctly.

Food Infrastructure

Food processing—cleaning, sorting, packaging, and canning of all kinds of agricultural and meat products—is typically an automated operation, performed on assembly lines by electrically powered machinery.

Like so many of the systems we have created our food system has worked us into a corner. We would have to build new machines and employ hundreds of thousands of people to do the cleaning, sorting, packaging and preserving of all the food required to feed our nation.

That said we are in luck in that most of it grows in the nation. Many countries struggle to feed themselves on domestic product. Still, much of our farming is based on gas powered equipment as well. So, we would be stifled there as well.

Refrigerators and freezers would stop working immediately after an EMP strike and the food will spoil in a matter of days. 

Emergency Services

Whether we measure the effectiveness of emergency services by their access to energy, emergency supplies or ability to communicate it’s clear that these services will be insufficient. We have very real deficiencies in our emergency systems in today’s fast paced world. An EMP would place the burden of emergency services on local resources only. In areas like Manhattan there simply wouldn’t be enough to go around.

Space Systems

A high altitude EMP could damage satellites directly. There is some debate on this topic. What is not up for debate is that ground communications to those satellites will be disrupted. That is crucial because most satellites operate unhindered after the initial programming. The ping back of information from the satellite is often what counts. On the ground there would be no way to receive that information or communicate additional programming to those satellites above.

Keeping The Citizenry Informed: Effects On People

According to the Commission:

The human consequences of such a scenario include the social and psychological reactions to a sudden loss of stability in the modern infrastructure over a large area of the country. Loss of connectivity between the government and its populace would only exacerbate the consequences of such a scenario.

Failure of the vast array of systems mentioned would cause wide spread panic and it will be imperative that the public is communicated with. One of the greatest villains to arise following an EMP could be the vacuum of information to the public.

When you read stories about the world being thrust back to the 1800’s an EMP can truly have that effect. However, this is not an apt scenario. Instead we would have to figure out how to run a country like it were the 1800’s while living in the shell of a 21st century world. The hurdles may be far too high to get over.

    Water will be a huge issue and the first priority for our family since we get our water from a well. We plan to use our Emergency Well Tube (www.emergencywelltube.com) in a crisis to maintain our ability to get drinking water from our well.

      Assuming you have stored all your information on some electronic media device, and assuming that you have satisfactorily safeguarded that media in a faraday cage, and assuming that you have a solar charger that will recharge the batteries powering your electronic media device, how long are those batteries good for? Two years? Three? Five? The batteries in my laptop are good for about three years and then it is new battery time. I guess one could squirrel away replacement batteries and hope that usage played a part in the useful lifetime of a battery as opposed to just deterioration with age. BUT whatever you do, at some point in time your batteries will be dead and not rechargeable. Then what? The 500 books you have stored on your laptop or whatever are lost forever. There was a time between about the 1860s and the end of WWII when paper was high acid paper. You could tell because it got brown and crisp fairly quickly. The Library of Congress has a significant problem with trying to convert that high acid paper so that they can preserve the vast store of books they have written in that time period. Since about the 1960s or perhaps sooner, paper was made with a different process and lasts much longer. Properly cared for, paper has a life in excess of 300 years. All the knowledge you put away on paper will be there long after all the battery devices have faded away. You will be able to pass on the knowledge you have stored to your progeny or to others who need it. I wrap all my reference books in a double layer of heavy duty saran wrap and make sure that the edges are sealed down good and tight. If I need to refer to the book after it is prepared for storage, it is an easy matter to remove the wrap and replace it with new. The plastic wrap seals out moisture and bugs. I suppose a further step would be to seal it in a nitrogen filled sealed bucket, but that adds too much work to store and remove if needed. When one considers how long it takes government to respond to limited emergency situations and how long it takes government to ameliorate the damage from the emergency situation, a significant event such as an EMP attack, a CME event or even just a simple attack on multiple electricity generating facilities will take the government a minimum of six months to decide if something has really happened. Another six months of fingerpointing about who is at fault and then, maybe, they will start to take some action in response to whatever emergency has taken place.

    The effects you have listed would occur nearly simultaneously. The only variable would be for backup generators. Once their fuel supply is exhausted, which could range from a few hours to a few days, the systems that rely on backup power would also grind to a halt.

    I think you are being overly optimistic regarding our food infrastructure. Without fuel and harvesting equipment, crops would rot in the field. The Commission report projects that up to 90% of the U.S. population could die within the first year following an EMP event that brings down the national power grid.

    The mega electric transformers that support the flow of power aren’t even manufactured in the U.S., and it takes more than one year just to build one.

      I have read several authoritative articles by electrical engineers who say that the is is not the solar panels, per se, although you could get some minor degradation in output. The real issue is the circuit boards, which could be damaged or rendered useless in an EMP event. Do a search with the words “EMP damage solar panels,” or variations on that. The articles are out there, but I think they are two or three years old.

    Don’t forget the nuclear power stations running on an alternative fuel source to keep the reactors cool that will run out eventually. Then it will be a nuclear meltdown and additional lives will be lost and areas permanently comtaiminanted.

    Don’t take too much comfort in the idea that America grows a lot of food. Much of the ‘food’ we grow is animal feed and humans usually cannot digest the types of grain used for animals or ethanol. Most food in America travels an average of 1500 miles to reach our kitchens. So we need gas to power the farm equipment, petroleum based agricultural chemicals, and gas to ship to market, fuel for heat to process food, and refrigeration or freezers to keep food edible. We may have enough farm land to grow enough food for our nation, but people don’t live where the food is. If you think you could always grow a garden…try it this summer and see how hungry you’d be if that was all you had to eat.

      A comment like this does little to add to intelligent discussion. People come to this site to get information about surviving catastrophic events. None of us is an expert in what will happen in the event of a large CME event, an EMP attack which will be designed to inflict maximum damage or a standard attack on our grid system which is very vulnerable to such. While it may be your opinion that we are not vulnerable to such events, that is fine and you are certainly entitled to it. Perhaps many U.S. citizens are much more self-sufficient than is generally believed and it would be our hope that your views are correct. Yet you offer no evidence to support your opinion, if it is valid, and end your post with a vulgarity that adds nothing to the discussion. If you are not going to post factual information, please refrain from posting at all.

      As an interesting aside, I am currently reading a book about the Crusades and sometime in the 11th century there was an apparent CME event. The crusaders reported seeing aurora borealis as far south as south of Antioch in what is, I believe, current day Syria. Of course, then the internet was mainly trumpets and drums for those close by and a fast horseback messenger for those somewhat further away, so it was merely, according to the crusaders, a sign from God that they were on the right path. No other indication of the strength of the CME event other than how far south it was seen. It would appear to me, not being a solar scientist, that would make it somewhere on the order of the Carrington event which blew out telegraph facilities all over the northern hemisphere. I doubt that there were any telegraph facilities in the southern hemisphere at that time, but I could be in error.

    Re: Keeping people informed. There is an active program to make sure that there are broadcast stations still viable post-EMP. Have a hand crank/solar powered radio (or 2 or 3) shielded and in your preps. Most of these stations are AM, but there are a few FM’s scattered around.

    The Amish live without this stuff every day. The beginning, shuffling people around, will be tough, but Americans are very resourceful. I am certainly not above harvesting at local farms in return for food. Now if it happened in winter, that might be a real problem (except in AZ and SoCal).

      Jan Bo,
      While you are correct that crops are grown in southern and central Arizona year-round, the farmers still rely on fuel for tractors, electricity to pump water, fertilizers that they cannot store, and seed that they must purchase from sources that are not nearby. Transportation of harvested crops (in refrigerated tractor-trailers) is essential.

      I drive through many square miles of agricultural fields several times a week on the 303 Loop, heading into Phoenix. There are several hundred thousand people much closer these fields than you probably are, assuming that you could get to these farm fields on foot in the first place.

      Without fuel, these fields cannot be cultivated. Without electricity or fuel for generators, the crops cannot be watered. Without harvesting combines and transportation, the crops cannot be moved to processing facilities for transshipment.

      Assuming that any crop survives long enough to be harvested, you would be fortunate if it was sweet corn; but you are just a likely to end up with a supply of radishes as payment.

      My guess is that the farmers will have hired armed watchmen long before you reach their fields.

    EMP is a threat that many people believe is just a prepper sweet dream and not something that could actually happen. The fact is it’s not only possible, but it’s actually likely should anyone ever get serious about taking the US down. If we ever get past saber rattling with Russia, the threat of us getting hit with an EMP is going to skyrocket.

      EMP devices, relatively speaking, are rather cheap to make which allows the lower tier bad actors this ability as well as the larger nations. The threat is real and approaching probability as opposed to possibility.

      I have to agree, Rick. I haven’t thrown a saddle on a horse in over fifty years. My wife doesn’t know how to spin yarn and anyway, I sure am a little short on how to shear a sheep. Yeah, I got it. You hold the sheep down and give them a buzz cut. I feel confident it is just a little more complicated than that.

      I generally know how milk is obtained from a cow, but as to the actual technique, I am clueless. I would like to see a few more knowledgable articles on this site about the day in and day out mechanics of raising chickens, rabbits, goats, pigs. The sum totality of what I know about raising any of these common animals can be written easily on a 3″ x 3″ post it note. In the 1800s everybody knew how to raise any of those animals. Even 13 year olds knew more about the subject than I.

      True, DJ, however, trying to cram a lifetime of acquired knowledge into the time available is a daunting task. I am slowly acquiring a library of books pertaining to topics of which I have little knowledge, but animal husbandry is more than a matter of studying how to milk a cow from a textbook. Sure, I have read how one goes about it. I have watched videos and I think I have most of it down. but there is so much more than just the mechanical part of milking a goat, cow, camel or any other animal mankind has used to obtain milk and that so much more is where lifetime experience comes into play. In the 18th century, I am sure most 13 year olds knew how to milk a cow and all the sundry little tidbits of knowledge that come from a couple of years of hands on.

    It was a couple of years ago. That a cruise line ship was dead in the water. I am a retired Cheif Engineer. These are powered by electrical motors. You have generators for each motor, just like locomotives. You have back up generators for each motor, for service purposes. Then you have at least 2 generators for power to the ship for all your other electrical needs. On the older ones you had a third, that had a separate fuel supply. Just in case you got a load of bad fuel. This ship had to be towed in. No explanation was given why the ship couldn’t even keep the toilets working. It had lost all power. These Generators have separate wiring in case of over loads. There is only one thing that can kill at least 7 generators, where a Cheif Engineer can’t get power back online. Especially after a week. Every electrical system had to be fried. We carried spare parts. So even the spare parts had to be fried. I think someone was testing an EMP weapon. That’s the only logical explanation for them to be without any power for almost 2 weeks I believe. They were discovered & towed in. But you never heard how this could have happened.

    One thing to consider regarding our post-EMP water infrastructure, is that our waste water treatment facilities will no longer be operational once their generators run out of fuel, a few days after the EMP.

    My point is that if your home is on a sewage conveyance system, the sewage is going to start backing up into the sewer mains and into homes.

    Homes in low lying areas of communities will be the first to have sewage coming up their toilets, tubs, showers, sinks, etc. These low lying areas rely on sewage lifting (pump) stations to convey the sewage to higher elevations, where it can then flow by gravity to the waste water treatment plant.

    This problem will release toxic and explosive gases like hydrogen sulfide and methane into homes, buildings businesses, and overflowing sewer manholes. Disease will also be rampant in urban areas because of this, as well as fire and explosions.

    This is yet another reason to get out of the cities and into the country. If you can, get a home on some acreage with its own septic system.

    I worked for several years as a grocery manager at Walmart. They have only a few days of food in them and very little in the back. They are dependent on multiple trucks a day to restock grocery daily. All this runs on gas. Gas is pumped by power. No Power, no gas, no trucks, no groceries. Starvation will be rampant. People will riot and kill for food. At that point it is too late to plant gardens and grow your food. Our large factory farms will not be able to operate. No fuel for plowing, planting, harvesting or shipping. You will be on your own. This event will happen someday and it will be without warning. By then it will be too late. You will be competing with millions of starving, well armed, desperate people for the few resources available. Good Luck. Your only option is to be prepared now. You must have adequate food and supplies to last until the bulk of people have died and the situation stabilizes. Books on skills are a good idea but you need to practice them now. Learning how to organically garden when you are desperate is a mistake. Learn now. Even with a couple years food, at some point you will have to produce food. The power will not come up, anytime in the near future if ever in our lifetime. How is a destroyed society going to replace what we had, when we don’t have any power to produce it. The government will collapse, don’t count on them but do count on strong men to arise in local areas. A lot of people are worried about their phones in these comments, why? The systems that make them work will be toast, the internet too. Someone mentioned the Amish. You should visit their communities and study how they live, because that is the future at somepoint.
