Collapse, you say? Part 2: Inputs and Outputs

Waves breaking along the Lake Huron shore—and this on a relatively quiet day.

The title of this series of posts comes from the typical reaction you get when suggesting that our civiiization might be collapsing, "Collapse you say, surely not!" In my last post I said that I am convinced it is already happening or at least will happen at some point soon. Then I went on to explain what I mean by collapse—the process by which a civilization declines in its ability to provide the necessities of life to its members, the end result being that people are forced to fend for themselves or perish.

It seems to me that this is in fact happening today—that for all but a tiny minority at the "top", things are getting continually worse. The how and why of this process is the subject of this post and the ones that follow it.

The means of production and distribution that provide us with the necessities of life in modern industrial civilization require certain inputs and produce certain outputs. Today I want to the look at the problems posed in acquiring those inputs and disposing of those outputs.

I would guess that it's clear that by inputs I mean the energy and materials required to make the things we need. But what I mean by outputs may be less clear. I am not referring to the goods that are produced from the inputs, but the waste products produced in the process and the garbage that is left over when we are done using those goods.

But why should these inputs and outputs constitute problems?

Conventional thinking has our civilization in a box, separate from our planet and its ecosphere. The inputs (energy and materials) our civilization uses come from sources that are seen as essentially infinite and the outputs (waste heat and waste materials) are discharged into sinks that are also seen as being essentially infinite in size. Given all that, no reason is seen for progress—economic growth in this context—not continuing for the foreseeable future. This way of looking at things typifies some of the blind spots of modern thinking on economics and business.

Figure 1

Figure 1 illustrates what I am talking about. As long as there were relatively few people on our planet, and they weren't consuming excessively, it's easy to see how we might have looked at things this way. But now that we are well on our way to filling up the planet—or more likely well beyond that point—this is no longer valid. And sure, many people are aware that this is a very unrealistic picture, but the people who are running things, even those who verbally acknowledge the realities, continue to act as if there are no limits built into the system. In a future post we'll look at why this is so, but for now it suffices to say that it truly is the case.

Figure 2

Figure 2 is a different diagram, which provides a more realistic depiction of things as they exist today.

First of all, our civilization exists on a finite planet, entirely within that planet's ecosphere, with no real separation from it (note the dashed border). Our inputs are taken from that finite source and our wastes are discharged back into that same finite space, used as a sink for waste heat and all our material wastes. This has some truly nasty consequences.

Inputs and outputs come in two forms: energy and materials. Energy flows from more concentrated to less concentrated forms, and regardless of where it comes from, is eventually radiated away from the planet as waste heat. Because of this, at any one level, we only get to use energy once. Materials stay around and can be reused, but generally change from more organized forms to less organized, (and less useful) forms as time passes.

For the planet itself, on the relatively short timescales we are considering, the only significant inputs and outputs are in the form of energy—sunlight in and waste heat out. This means that the planet isn't a closed system and incoming energy can be used to arrange matter into more complex forms, converting the energy used to a less concentrated form in the process. That's the good news—the rest of the news is bad.

Outputs

Let's look at outputs first, since that will make it easier to understand some of the problems with inputs. As I said, the outputs I am talking about are the wastes from processes within our society, and the garbage left over when we are done with the products of those processes. We simply throw these things away, but the trouble is that there is no such place as "away". The sinks into which we dispose of wastes are part of the very same environment where we get our inputs from, so this is much like shitting in our own nest. And in a great many cases it is not necessary at all. Many of these end products could, with relatively little effort, be fed back into the processes, and not treated as "wastes" at all.

That we haven't "circularized" our use of materials is a really bad sign. Why we continue to do this is inherent to the internal workings of our civilization and I'll go into the details of that in a future post. For now it is sufficient to understand that as long as that civilization exists in its present form, it's outputs will continue to be a problem.

There are a great many different types of pollution, but for our purposes today I'll concentrate on two particular type of waste—carbon dioxide and methane.

Carbon dioxide (CO2) is produced in the burning of fossil fuels and biomass, and in the processes we use to make things like steel and concrete, essential building materials of our civilization. CO2 is a major contributor to the greenhouse effect and consequently climate change, and is also the cause of ocean acidification.

Methane (natural gas, CH4) has been touted as a replacement for coal and oil since it gives off less (but not zero) CO2 when burned. But it is an even more potent greenhouse gas than CO2. Between the wellhead and where it is used a great deal of methane leaks into the atmosphere—probably enough to overshadow any reduction in CO2 released by burning natural gas instead of other fossil fuels. Methane is also produced during the decay of organic matter and by the digestive systems of many animals. Warming due to climate change is releasing methane currently trapped in permafrost and in methane clathrate hydrates at the bottom of the Arctic Ocean, further intensifying the warming process.

Ocean acidification the lesser known evil twin of climate change, occurs when CO2 is dissolved in water. An estimated 30–40% of the carbon dioxide from human activity released into the atmosphere dissolves into oceans, rivers and lakes. Some of it reacts with the water to form carbonic acid. Some of the resulting carbonic acid molecules dissociate into a bicarbonate ion and a hydrogen ion, thus increasing ocean acidity (H+ ion concentration).

Increasing acidity is thought to have a range of potentially harmful consequences for marine organisms such as depressing metabolic rates and immune responses in some organisms and causing coral bleaching. A net decrease in the amount of carbonate ions available may make it more difficult for marine calcifying organisms, such as coral and some plankton, to form biogenic calcium carbonate, and such structures become vulnerable to dissolution. Ongoing acidification of the oceans may threaten food chains linked with the oceans.

(Thanks to Wikipedia for the last two paragraphs.)

These are food chains that we sit at the top of, with many people, especially in poorer nations, relying heavily on seafood for protein.

Climate change has been in the news a lot lately, with a wide range of people expressing concern about its negative effects on our future. If, despite this, you are still a doubter or denier, you're in the wrong place on the internet, and need not bother leaving any comments. In my experience, if you scratch a climate change denier, you will find beneath the surface a rich person who is worried about losing their privilege.

So, climate change is real and it is driven by increases in greenhouse gases (CO2 and CH4 among others) in the atmosphere which cause the planet to retain more of the sun's heat. It has also been called "global warming", since it causes the overall average temperature of the planet to going up. The high latitudes in particular are already experiencing temperature increases. Eventually this is going to cause enough melting of glaciers to make for a significant increase in sea level.

In the meantime, climate change is also causing more frequent and heavier storms, which combined with even small increases in sea level, are causing a lot of damage along the oceans' shores. Such storms are also causing more frequent and serious flooding of many rivers.

Climate change is also intensifying droughts in many other areas, and in some of those areas this is leading to wild fires.

How does all this tie into collapse?

Storm surges, high winds, river flooding and wild fires are doing a great deal of damage to human settlements, at a time when our economy is struggling and the added cost of rebuilding can scarcely be afforded. Especially since we tend to rebuild in the same areas, leaving rebuilt settlements just as exposed as they were before.

The effects of climate change on agriculture are even more serious. In the ten or so millennia since we started practicing agriculture the climate on this planet has been particularly friendly to that endeavour. Farmers have been able to count on reliable temperatures and rainfall. This is now starting to change and as the rate of that change picks up over the coming decades, it is going to be very challenging to adapt to. This at a time when we are struggling to keep up to the demands of a growing and ever more affluent population for food and when there is little left in the way of wilderness to expand our farms into.

Even if climate change was the only problem we faced, it is serious enough to place the continued survival of our species into question. We are facing, to quote Jem Bendell, "inevitable collapse, probable catastrophe and possible extinction."

The threat of climate change is serious enough that most people who worry about such things at all are concentrating on it alone. Unfortunately, they are largely ignoring looming problems with the inputs required by our civilization.

Inputs

The problem with inputs is "resource depletion". We live on a finite planet and we can really access only a small part of it—the lower part of the atmosphere, the oceans and a few thousand feet at the top of the crust. Within that volume, there are finite supplies of the resources that we rely on.

Several problems result from the way we access and use those resources.

We generally access the lowest hanging fruit first. This means that the most convenient, easily accessible and highest quality resources get used up first. That makes sense as far as it goes, but it means as time goes by we are forced to use less easily accessible and lower quality resources. This takes more energy and more complex equipment, and is more costly.

Many of the resources we rely on are non-renewable—there is a finite amount of them on this planet, and "they" aren't making any more. Further, we use them in very wasteful ways. It is important to be aware here that, even at best, there is always some irreducible waste in our use of any resource, but currently we tend to make things, use them once and throw them "away". This means that depletion of many resources is happening thousands of times more quickly than it really needs to, and as I said in the section on outputs, that waste is accumulating in the environment.

Some of the resources we use are renewable, but the processes by which they are renewed work at a limited rate. We are using many of these so called renewable resources at greater than their replacement rate, and so they too are becoming depleted.

Conventional economists will tell you that when a resource starts to get rare, its price goes up, encouraging the development of substitutes. This is true to some limited extent, but many of the most critical resources simply have no viable substitutes. Not unless we are willing to make significant and unwelcome changes to the way we live.

At this point, we should look at some specific resources and the unique problems each of them presents.

Energy, Fossil fuels

Despite what conventional economists would tell you, energy (not money) is actually the keystone resource for our economy. Nothing happens inside our civilization without energy as an input and degraded energy (waste heat) as an output. Money functions as a medium of exchange, a unit of account and a store of value, all of which is very useful, but energy is what makes the economy function and grow. About 80% of that energy currently comes from fossil fuels (primarily coal, oil and natural gas). The remaining 20% comes from sources that we can only access using equipment that is both made using fossil fuels and powered by them.

So, our civilization is utterly dependent on having a cheap and abundant supply of fossil fuels. "Peak Oil" enthusiasts have been saying for decades now that we'll soon run out of oil and things will come to a grinding halt. In fact, though, there are still large quantities of hydrocarbons to be found in the earth's crust, so you might ask, "What's the problem?"

Well, there are two problems with continuing to burn fossil fuels.

One is the consequences for the climate of burning hydrocarbons and releasing ever larger amounts of carbon dioxide into the atmosphere. This is a very serious problem, for which we are having trouble finding and implementing any sort of solution.

The other problem, I'll be calling it "the surplus energy problem", is in many ways more complex and more serious.

Because we use various forms of technology to access energy, many people think that technology makes energy, and with improved technology we can always make more energy. Or, in this case, access the difficult to access hydrocarbons that currently remain in the ground. But in fact, the opposite is true—technology uses energy and won't work without it.

The energy that remains after we've powered the processes used to acquire that energy is referred to as "surplus energy." For instance, the technology used to drill oil wells and pump crude oil out of the ground uses energy. Back in the day, it used to take the energy equivalent of about one barrel of oil to get 100 barrels of oil out of the ground, leaving a surplus energy equivalent to 99 barrels of oil. This is usually expressed as "Energy Returned on Energy Invested" (EROEI), in this case 100/1, giving an EROEI of 100. Another way of looking at this is to talk about the Energy Cost of Energy (ECoE). In this case that would be 1/100, or 1%. Note that both these numbers are just bare numbers without units, and most significantly without a dollar sign in front of them. The "money cost" of energy is another thing entirely and since it is influenced by speculation on future supply and by fluctuations in demand (as we have seen in 2020 during the pandemic) it is not a reliable indicator of the actual cost of energy in energy terms, or the future availability of energy.

Conventional oil discoveries have not been keeping up with depletion for some time and our use of conventional oil actually peaked in the last few years. So we have been forced to switch to lower quality and more difficult to access sources. Conventional oil today has an EROEI ranging from 10 to 30. Tight oil and gas (from fracking), heavy oil and the "dilbit" (diluted bitumen) made from tar sands all have EROEIs less than 5, or ECoEs of 20% or greater.

"So what?" you might say. As long as the net amount of energy available is sufficient to power our civilization, what's the problem? Well, it's not just the amount of energy available from any particular source that really counts, but the EROEI. Or more precisely the weighted average of the EROEIs of all the various energy sources an economy uses. That number needs to be around 15 or more to keep that economy growing.

When the average EROEI goes below 15, growth slows and eventually stops and it becomes difficult to raise enough capital to even maintain existing infrastructure. Why our civilization needs to grow is a topic for another day, but it certainly does. This is what most people are missing about energy. Yes, a country can use debt to finance access to low EROEI energy resources in order to keep the economy going. But only for a while, until its economy contracts to the point where things begin to fall apart. This is certainly the case in the US. Fracking has made sufficient energy available, at what seems like a reasonable dollar price, but the real economy is mysteriously contracting, and debt is continually growing. Both economists and politicians, while putting on a brave face, are hard pressed to do anything about it, because they don't understand the surplus energy problem.

As we saw in the section on "Outputs", there are pressing reasons not to continue burning fossil fuels. But even if that were not the case, it would not be possible to continue running a growth based industrial civilization on the low EROEI fossil energy sources now available to us. For this reason alone, collapse seems like a sure thing to me, and I would say it has been underway since oil production in the continental U.S. peaked in the early 1970s.

But, you may say, what about renewable energy sources? Like non-conventional fossil fuels there are large amounts of energy available from sources like hydro, biomass, wind, solar and so forth. A great many people today believe that renewables can replace fossil fuels and solve both our surplus energy and climate change problems. In fact it has become very unpopular to challenge that idea, but I am afraid I must do just that.

This post ened up at over 6000 words long, enough to try the patience of even my most loyal readers. So I have split it in two at this point, leaving the second half for my next post, which will pick up from here and cover renewable energy sources, ecosystem services and fossil water.

Responding to Collapse, Part 12: coping with longer power outages

Volunteer butternut squash and gourds
that grew from one of our compost bins this year.


Dealing with power outages, Section 2

This is the second of the four sections I promised in my last post where I talked about the most basic preparations you should make for short power outages.

Today we'll talk about some further preparations that you can make that aren't (for the most part) terribly expensive and which will help see you through longer outages. There are some pieces of camping equipment that can be quite useful when the grid temporarily lets you down, and useful for camping, as well. This still comes under the classification of coping with a failing BAU (Business as Usual), rather than adapting to a failed BAU.

Because camping often takes you out of contact with the power grid there is a range of camping equipment that uses energy sources other than electricity or allows you to generate your own electricity. When camping, or during an outage, you want to use as little electricity as possible, so that the equipment you need to generate it is as small, simple and inexpensive as possible. Electrical appliances that turn electricity into heat are the first thing you want to get rid of in favour of using some sort of fuel directly to produce that heat. Things like furnaces, heaters, stoves, toasters, and so forth.

Two different type of small propane cylinders
and a can of Coleman fuel

The fuels you'll most likely use are either propane gas or white gasoline (also known as naphtha or Coleman fuel). You can easily store enough of these fuels to get you through an outage a few day to a couple of weeks in length. There is quite a bit of discussion on the internet as to which is better, liquid fuel or propane. All the camping equipment I have uses liquid fuel, which costs less, is less bulky, is safer to store, handle and move in a vehicle, and works better in the cold. It is a bit more complex to use. I do have a propane barbeque and a propane torch for soldering and such.

I keep two or three cans of Coleman fuel on hand, and I've read that as long as the can hasn't been opened it stores quite well. I've left fuel in partly empty cans (with the cap closed) for years and then used it with no problems, so I'm not sure how much of an issue stale fuel really is.

The choice between liquid fuel and propane gas is largely a matter of personal preference. If you go with liquid fuel, have a funnel on hand for filling and a spare set of guts for the air pump. And the one thing you must not do is to fill Coleman appliances with liquid fuel indoors. That's asking for a fire. Make sure you go outside to a well ventilated area with no nearby sources of ignition.

There is also a lot of discussion on whether it is safe to use this equipment indoors, much of which is pure bunk. For safety's sake crack a couple of windows to get some ventilation and have a carbon monoxide detector in the area where you'll be using the equipment. I have found when using even a small appliance like a mantle lantern indoor in the winter that it generates enough heat to make up for the loss from windows that are slightly open.

At this point I should address the issue of natural gas. Many of you probably have a natural gas supply connected to your house. You'd think that this supply would be unaffected by electrical outages. Sadly this is unlikely to be true. In the majority of cases, that natural gas supply is pressurized by electrical pumps that won't be working during a power outage. Some large trunk lines are pressurized using pumps powered by natural gas, and I am told they will probably continue to work during a power outage. But their controls are probably electrical, and unless they have battery backup and/or a backup generator, they won't work either. So I wouldn't rely on your natural gas supply to be impervious to power outages. In any case, most of your natural gas appliance have electrical control and ignition, so they won't work during an outage. Unless you have a generator (see more below).

Perhaps some of you have propane appliances supplied from a large tank that the propane company installed next to your house, and which they fill regularly. This is a source of energy that may well carry you through a power outage. As with natural gas appliances, most propane appliance have electrical controls and ignition, so you need a generator, or a way of hooking you camping style propane appliances up to that big tank. There are a couple of other concerns. Most propane companies work on just in time delivery and if your tank is almost empty when an outage happens, your propane supply won't last long. Perhaps you can talk you propane supplier into a different delivery arrangement. And during high use periods like cold snaps the local supply of propane may run out and you won't be getting any deliveries, even if the power is on.

At this stage you probably still don't want to make majors changes to your lifestyle—when the power is out, you'd like to be able to have some electricity, for a variety of uses that aren't easy to power with other energy sources, or to provide control power to appliances that burn natural gas, propane or even fuel oil.

If you just want a small amount of power, there are small battery banks which store enough power to recharge your phone, tablet or even your laptop. The simplest ones can only be recharged from 120V AC, but the more sophisticated ones (know as solar generators) can be recharged from a solar panel, 12V car outlet, or 120VAC, and they sell foldable, portable solar panels which will charge these battery banks. They have power outputs at 120V AC, 12 VDC and powered USB ports for phones and such like.

I don't have one of these devices, so I can't speak from personal experience, but while they do appear to offer a certain degree of convenience, they are quite expensive and they really don't store very much power—a few amp hours at the most. Certainly not enough to run typical refrigerators or freezers, for instance. If you want to go with solar power, you might be better to consider the full fledged solar panel, inverter-charger and battery system that I'll be discussing in my next post.

Generators

Our Generator

The obvious thing here is to get a generator. I finally gave in and bought a generator a couple of years ago, and last fall we installed a wood stove. We have electric heat and it just isn't practical to have a large enough generator to run our electric furnace, so the two decisions went together.

Our generator is a gasoline fueled, 5500W model made by Champion Global Power Equipment that we got on sale at Canadian Tire for less than $1000 Canadian. (Canadian tire is a chain of automotive/hardware/houseware/sports/garden stores here in Canada. If you live outside Canada don't know what you are missing.) If I had deeper pockets I would have gotten a Honda generator—in my experience Honda power equipment starts more easily, is more reliable and lasts longer, but also costs a lot more. So far the Champion has started easily and run well, even in the winter. This was the smallest generator I could find with a 240V output, needed to run our furnace fan and some of my woodworking equipment.

Some may wonder why I didn't get an "inverter-generator", which uses a DC generator and solid state invert to produce AC. They offer better fuel economy if you want to run your generator pretty much continuously and under light loads most of the time. And they usually are set up to run quite quietly for use in campgrounds. But they are more expensive and more complicated. I intend to run my generator only when there is really something for it to do, and I needed to get the most bang for my buck.

Draining stale fuel form generator
into spare jerry can.
On the left, two jerry cans full of gasoline.

Generators do require some on-going effort to keep them in good condition. I start ours once a month and run it for a short while, then shut off the fuel valve and let it run dry so as to stop fuel from leaving deposits in the carburetor. Fresh fuel is also very important. I have three 20 l. (5 gallon) jerry cans, two of which I keep full of fuel. Before running the generator each month, I drain its fuel tank into the third jerry can and empty that can into my car's fuel tank. The other two cans are labelled "odd" and "even" and in odd numbered months I empty the "odd" can into the generator and then fill it with fresh fuel at the gas station. Same for the "even" can in even numbered months.

Like most generators, this one will run about 8 hours at 50% load. My jerry cans hold the same amount of fuel as the generator's fuel tank, so I'm good for 24 hours at half load. Of course, most of the time I'll to be running the generator at less than 50% power and I have no need to run the generator round the clock, especially with the wood stove and Coleman equipment. I expect that during an outage I would run the generator for an hour or so morning and evening to cool down our freezers and fridge, and do anything else that I need power for at those times. So I hope to be good for outages up to a couple of weeks long.

I got a gasoline fueled generator because my car uses gasoline and I can rotate stale fuel into the car rather than throwing it away. And during an outage, if I desperately have to go somewhere and gas stations aren't operating, I have some spare transportation fuel on hand. If you have a diesel vehicle or you live on a farm with diesel equipment and have a big tank of diesel fuel in your equipment shed, you should consider a diesel generator. If you have propane appliances already and a large tank of propane that your supplier fills regularly, you might want to consider a propane fueled generator.

I just googled "does diesel fuel get stale" and apparently it does after a few months, so you'll still need to rotate your diesel fuel. This will be much less of an issue with propane.

There are a few other complications with owning and using a generator that we should discuss.

Some maintenance will be required, such as changing the oil regularly (check the owner's manual for how often) and cleaning or changing the spark plug. And eventually you'll want to take that generator to your local small engine place for a complete overhaul.

Because the gas tank is full of fuel, a generator is a fire hazard and you shouldn't keep it in your house. I keep mine in my backyard tool shed.

When it is running, the exhaust is a problem (carbon monoxide and so forth), so it should be run outdoors or the exhaust vented outdoors, and not upwind of any ventilation intakes.

Because this is a piece of electrical equipment it needs to be kept dry, and this includes keeping it dry when it is running outdoors in the rain. A leanto made with a trap and some 2X4's would do in a pinch. Or you might want to build a very well ventilated shed to both store and run the generator.

Hooking your generator up to the electrical system in your house in a way that is safe and meets the requirements of the electrical code is a job for an electrician. Until that job is done, you can hook up individual loads to the generator with extension cords. Using a cord with two male ends to plug your generator into the house system is dangerous and illegal. The main concern is that if you leave your main breaker or switch closed, you'll be livening up the whole grid and the people who are working on it trying to restore power. It is no exaggeration to say that that deaths can result from this.

My generator is quite noisy and I don't plan on running it through the night. You can get generators that run fairly quietly, but they are more expensive and usually come in smaller sizes, so I chose not to get one. During an outage, that noise is going to attract attention. In the little town where I live, I expect my neighbours to drop by and see if I have power. When outages become more common, I expect we'll develop a tradition of generator parties, and I'd be pleased to host one.

I hear American survivalists and preppers talking about noisy generators attracting unwanted and possibly dangerous company. They'll probably shake their heads and laugh at my idea of a generator party, but things really are different here in Canada. As my American daughter-in-law, who grew up in Camden, New Jersey, and lived in Jacksonville, Florida, before coming here, says, "it's like moving to a different planet."

Single Mantle
Coleman Lantern
Spare mantles on the right.

OK, having covered all that information, now let's run through our list of services with all this in mind.

Lighting

You can get battery operated lanterns that are quite effective, but I would advise getting a Coleman mantle lantern. They generate a bright white light that is barely distinguishable from the electric light we are all used to and give off a fair bit of heat as well. The mantles are fairly fragile when in use, so keep a couple of spare mantles on hand. Kits of repair parts for the air pump on Coleman appliances are available and you should have one.

Water

Additional water storage would be a good idea, enough for a week or two, at minimum of a gallon per person per day. For two people for a week that's 14 gallons. The next step after storing more water is to have a water filter that can make surface water safe to drink. If you live near a lake, pond or stream, this will prove usefull.

Google will give you links to many types of water filters, but if you are looking for a tabletop filter that will turn the most unsavory surface water into something drinkable, Berkey or Doulton are the brands you want.

Filter elements

Our homemade water filter

They are a little pricey, though, and it is possible (I have done it myself) to put together a much less expensive DIY filter using a pair of plastic buckets that is functionally equivalent to the factory made filters, and uses the same filter cartridges. Here are a couple of links to instructions: 1, 2.

It is also a good idea to keep some 5 gallon plastic buckets on hand for carrying water. You'll find they actually come in handy for a great many purposes.

There are a variety of water treatment/filtration systems for use when camping or backpacking. I'm not really up to speed on these, so I'll include this link to a review of Best Backpacking Water Filters & Purifiers of 2019 to start you on your own research if you are interested.

Of course there are filters you can make at home using charcoal and sand, but I'm going to leave those for my next post.

If you have a well and a generator, best call your electrician and see what is going to be involved in powering your water pump from the generator. Many water pumps have a 240V motor, so you'll need a generator with a 240V outlet, a suitable extension cord, and some wiring at the pump to make it safe and easy to hook the generator up to it.

"Jenkins" Style Sawdust Toilet
with bale of wood shavings in front

Sewage

What I said in my last post applies here as well. Keep an emergency bucket toilet on hand, or go for a Jenkins style sawdust toilet . I have one of them tucked away in a secluded corner of my basement woodworking shop. If we were going to use it regularly, some ventilation to the outdoors would be needed.

I can recommend a couple of books on the subject of humanure: The Humanure Handbook by Joseph Jenkins, and The Scoop on Poop by Dan Chiras.

Food

I'm going to leave the issue of storing large quantities of food for a post in the near future where I'll discuss the ongoing availability of diesel fuel and its effect on supply chains. But it is a good idea to have enough food on hand to last two weeks at a bare minimum, assuming that many stores won't be open and regular deliveries won't be happening during an outage. The idea here is to store what you eat and eat what you store. Don't get taken in by those people who are selling expensive freeze dried emergency food.

Some of that food may end up getting served at a generator party, so plan accordingly.

Two burner liquid fuel Coleman stove, and large kettle

If you are in the habit of always eating out and don't normally keep much food in the house, you need to break that habit and learn how to cook as part of your collapse preparations. It is likely that most restaurants won't be operating during an outage.

The first long outage will catch a lot of people, both consumers and those working in the supply chain, by surprise. A rude awakening, but one that may lead to better preparation for future such problems.

Cooking

You won't want to subsist for very long on food that doesn't need to be cooked. I would recommend a two burner Coleman stove to use when your electric range isn't working. If you have a propane stove that will work without power you're in luck. Propane barbeques can also be useful when the power is out.

Spare parts for Coleman pumps

I recently acquired some spare parts for the pumps of my Colman lantern and stove. The cup on the right is made of leather and will work at much lower temperatures than the usual rubber cup, which stiffens up in the cold.

A big kettle for heating water for washing is also handy.

Refrigeration

At this level of preparation, refrigeration is a tough issue. My own response was to get a generator and plan to run it for short periods a few times a day to keep our fridge and freezer cold. Freezers will stay cold for a day or two without power (especially if they are full), but refrigerators only stay cold for about 4 hours without power and I expect to keep several bags or plastic bottles of ice in my fridge to extend that time (so I can get a full night's sleep if nothing else). I'm also shopping around for a "fridge thermometer" so I can tell how that's working.

There are refrigerators intended for off grid situations that are better insulated and take less power than typical fridges. And there are propane powered refrigerators of the type used in RVs. Both are pretty expensive, so I'm not seriously suggesting you get one at this point.

It is possible to turn a horizontal chest freezer into a refrigerator that takes very little power and stays cool longer. When you open the door, the cold air doesn't fall out, and they have thicker insulation than a regular fridge, so they stay cold longer and use less power. This would be particularly useful if you are setting up an off grid solar power system and need to keep your power usage to an absolute minimum but still want to have refrigeration.

Here are some links to instructions: 1, 2.

The only criticism I would make of these instructions is that it is pretty dumb to run the capillary tube for the sensor bulb under the door seal—hard on the door seal, and leaky. Instead, you can get the temperature sensing bulb in into the fridge through the drain valve and put some duct seal (industrial strength plasticine) around it for a good seal. The "old school" mechanical temperature controller shown in both those articles is definitely the way to go since it uses no power itself. Sometime ago I read another article where the author had gone to a lot of trouble to build an electronic controller that used less power than the fridge. It still used a bit of power, though—better to stick with the simple mechanical controller.

Awnings on the south side of our house

Cooling

As I said in Part 1, if you've chosen your location carefully, you should be able to get by without air conditioning, and just suffer through the few hottest days in summer. Shade and ventilation will help, and believe it or not, if you stay out of air conditioned spaces for a few days , you will get used to the heat. Try to take it easy though, until you've adapted.

Shade can be provided by trees and/or awnings. Trees take a while to grow, so it's best to look for a place that already has shade from tall deciduous tree, definitely on the south side and if possible on the west side. Or plant quick growing trees like mullberries, and wait patiently.

My house has lots of south facing windows from solar gain in the winter, but that's not a good thing in the summer. And it is in a location without trees and where planting trees isn't really practical. So I made up awnings to shade the windows that were picking up the most heat in the summer. They have to be put up in the spring and taken down in the fall, but it's worth the effort.

A well designed house can get quite a bit of cooling from natural ventilation, especially from cool breezes in the evening. It helps to have windows that open. This still just wasn't enough for our house, so I put in an attic fan which draws air in through the windows and pushes it out through the attic vents, cooling both the house and the attic in the process. This works best when it cools down after dark, which it usually does in our area.

Our wood stove

Heating

We have an electric forced air furnace, so when the power is out, we have no heat. We do have a catalytic tent heater that uses liquid Coleman fuel. It works pretty nicely in a tent and does OK in the house in a pinch, but it would be best to do the initial lighting outside and you really have to open some windows for ventilation.

There are space heaters that burn propane or kerosene and apparently are safe to use indoors and don't use electricity, or at least work OK on batteries, and aren't terribly expensive. Something to look into if you really don't want to get a woodstove, or simply can't afford one.

But perhaps it would be best to just get a wood stove. Especially if wood heating is common in your area, and there are people making a business of installing wood stoves and supplying firewood.

We did that last fall, and while it was a major expense (especially the chimney—we have a tall house), wood is still cheaper than electricity, so it will pay itself back over a number of years. Of course, there is a bit of work involved in tending a wood stove, but it seems worth it to me. Though I must admit that I am retired and often looking for something to do in the winter.

Communications

You should make arrangements for communicating with your family (and other house mates) who may be away at the start of an outage. Cell phone will be working for 2 to 4 hours and landlines for quite a bit longer than that.

It appears that CB radio is no longer a big thing, but amateur (ham) radio is. For those who are so inclined I would suggest taking up ham radio and joining a group who use their two way radios for emergency response co-ordination. Not for everybody, clearly, but a fun hobby for techies who like to talk to strangers.

Transportation

I don't have much more to say here than in the first section. Keep you vehicle's tank at least half full, and in a pinch you can use some of your stock of generator fuel in your car.

Bicycles are useful, even when the power is on. I have to admit that living in a hilly town I lust after a bicycle with electric assist, which could be charged by generator or maybe even by a solar panel if you don't plan to use it too much.

And of course, in a small town, walking is quite practical and something we should all get more accustomed to doing.

In Closing

Quite a bit of what I've advised here is not expensive and can be done even by apartment dwellers or if you are renting a house. Much of it would probably be a good idea even if you aren't preparing for collapse. And it will allow you to get through longer and more frequent power outages with relatively little suffering. But best not to kid yourself that this will give you much in the way of long term independence from BAU. We tackle that sort of preparation in my next post.
