Peak Resources & the Preservation of Knowledge

By Alice Friedemann    January 6, 2006

Last updated May 25, 2016

“Peak oil will affect more people, in more places, in more ways, than anything else in the history of the world”. Walter Youngquist, author of Geodestinies


After worldwide oil production peaks, there are no substitutes ready to make up the energy shortfall.  The immediate problem will be a need for liquid transportation fuels.

Liquid, renewable fuels, such as ethanol, biodiesel, and hydrogen, do not have a high enough Energy Returned on Energy Invested (EROI) to run civilization, let alone maintain the existing infrastructure, the majority of which was built when oil had an EROI of 40 to 100 (Hall 2003).

Liquid, non-renewable fossil fuels that could be used to replace oil, such as liquefied coal, require a tremendous amount of expensive infrastructure that needs to be built at least ten years before the world peak production of oil (Hirsch 2005).  We haven’t done that, nor is it likely we ever will, because after peak, fossil fuels will be rationed and apportioned to agriculture and other critical agencies (USDOE 1980).

We’re likely to lose many of the books printed on acidic paper between 1850 and most of the 20th century within decades. For the last twenty years, many books and journals have been printed on non-acidic paper and put on microfiche.  Both can last for centuries if kept at an ideal temperature and humidity.  But that isn’t permanent enough.   Librarians are aware of this, and have turned to computers as a way to preserve knowledge.  Some libraries are stopping the delivery of many printed journals and have them online only.

But microelectronic data storage systems such as magnetic disks, tape and even optical storage systems can only safely store information a few decades (Markoff 2015).

And computers are the top card in the house-of-cards complex civilization we built with coal and oil. Computers will be the first to go when supply chains fail as global trade diminishes.  Apple alone has hundreds of suppliers from over 25 countries, and each of these suppliers has suppliers all the way back to the mining of the ore.  Financial crashes, natural disasters, war, and oil shortages will break these super-long, super-fragile supply chains. Fossil fuel shortages mean that electric grids won’t be up all the time, or energy available to mine ore to make steel to make computers and storage media with.

Declining energy supplies are likely to trigger a global depression, resulting in political instability, which may trigger resource wars.

Preservation of knowledge needs to start immediately, while nations are still stable and wealthy.  Now is the time to consider how to preserve knowledge with a material that won’t decay, rust, mold, or shatter easily.  We should leave our descendants knowledge they can use and be amazed by, information to fuel the next Renaissance.


Since there are no alternative energy sources, except for fusion, which could possibly replace fossil fuels (Hoffert 2002), a priority should be the preservation of knowledge.  Fusion is unlikely to ever be harnessed as a source of energy, and certainly won’t be ready in time to save us from the impact fossil fuel decline will have upon civilization.

Fossil fuels enabled the human population to grow at a rate 133 times higher than all of human history before then (Hardin 1995).   Fusion would allow exponential growth to continue until we used up all of the other resources on the planet (e.g. water, topsoil), and lead to an even greater loss of human life and biodiversity.

There aren’t any alternative energy sources that can replace fossil fuels in the window of time left.  If only we’d listened to Jimmy Carter, while there was still a chance of reducing the inevitable tragedy relying on non-renewable energy sources would bring (Carter 1977).

We are about to enter a time of social, political, and economic hardship and instability, and these human factors will exacerbate the problem of declining energy.

Our lives depend on oil, natural gas, and coal for our food, clean water, sanitation, transportation, electricity, cooling and heating, cooking, and health.   These fossil fuels are composed of complex hydro-carbon chains that provide the feedstock for over half a million products, including plastics, medicine, paint, chemicals, etc.   We are utterly dependent upon the fossil fuels entwined in all aspects of our lives.  They have enabled our population to grow from one billion before coal to six and a half billion now (Smil 2000).

The biggest mistake people make about the seriousness of “Peak Oil” is assuming there is a technical fix.  This is understandable, given how virtually all articles in the press and scientific journals are about advances and breakthroughs.

Plan B

There is a “Plan B”.  Hirsch’s stopgap measure, Peaking of World Oil Production: Impacts, Mitigation, & Risk Management, is the most likely plan to be attempted as the energy crisis worsens.  The solutions are heavy oil, gas-to-liquids & liquefied natural gas, enhanced oil recovery, efficient vehicles, and coal liquids.  Notice that nearly all depend on using low quality liquid fossil fuels (which would increase global warming).  Some highlights:

  • The peaking of world oil production presents the U.S. and the world with an unprecedented risk management problem. As peaking is approached, liquid fuel prices and price volatility will increase dramatically, and, without timely mitigation, the economic, social, and political costs will be unprecedented. Viable mitigation options exist on both the supply and demand sides, but to have substantial impact, they must be initiated more than a decade in advance of peaking.
  • The problem of the peaking of world conventional oil production is unlike any yet faced by modern industrial society.
  • Oil is the lifeblood of modern civilization. It fuels the vast majority of the world’s mechanized transportation equipment – automobiles, trucks, airplanes, trains, ships, farm equipment, the military, etc. Oil is also the primary feedstock for many of the chemicals that are essential to modern life. This study deals with the upcoming physical shortage of world conventional oil–an event that has the potential to inflict disruptions and hardships on the economies of every country.
  • Use of petroleum is pervasive throughout the U.S. economy. It is directly linked to all market sectors because all depend on oil-consuming capital stock.
  • The world has never faced a problem like this. Without massive mitigation more than a decade before the fact, the problem will be pervasive and will not be temporary. Previous energy transitions (wood to coal and coal to oil) were gradual and evolutionary; oil peaking will be abrupt and revolutionary.
  • Even if efficient vehicles were mandated or a technology breakthrough occurred, it would take 10-15 years to replace the existing vehicle fleet. In 2004, …U.S. oil consumption was 20 MM barrels per day, two-thirds of which was in the transportation sector.
  • The implications for U.S. … mitigation of world oil peaking are troubling. To replace dwindling supplies of conventional oil, large numbers of expensive and environmentally intrusive substitute fuel production facilities will be required. Under current conditions, it could easily require more than a decade to construct a large coal liquefaction plant in the U.S. The prospects for constructing 25-50, with the first ones coming into operation within a three year time window are essentially nil.

Congressman Roscoe Bartlett (R-MD), a co-founder of the House of Representatives Peak Oil Caucus, said that we should not try to fill in the gap between supply and demand with the Hirsch plan, because after these measures run out, civilization will crash even harder, and these measures will damage the environment.

Another Plan B would be to build new nuclear power plants.   Since the issue that needs to be solved is liquid transportation fuel, nuclear power is irrelevant.  So are solar, tidal, and wind power.

Currently there is only enough uranium left to power existing plants for about fifty years.  If Generation IV nuclear power plants can be made to work, they could stretch U235 fuel for several millennia, as well as reduce nuclear waste considerably.

Per Peterson, chairman of the nuclear engineering department at the University of California, Berkeley, said that Gen IV might start being built around 2025-2030. These plants generate tremendously high heat, which could contribute to solving the liquid fuel problem by splitting hydrogen from water to convert low-grade heavy oils into high-energy fuel.   We’ve known since 1969 that we needed to build these types of reactors to stretch out nuclear fuel, but still haven’t figured out how to do this safely (Hubbert 1969).

Saudi Arabian oil reserves

So here we are close to Peak Oil (Deffeyes 2001), and we haven’t started on any Plan B.   We‘ll know we’re at Peak Oil production when Saudi Arabian oil extraction declines, because they have such a huge portion of the world’s remaining oil, nearly a quarter of it.  But Matt Simmons believes that they may have exaggerated their reserves and have other problems (Simmons 2005):

1)      There’s a 35-40% probability that Saudi Arabian oil fields “could fall over a 30 month period of time by 50-70%”.   Fields that are produced too quickly, (which has happened in the past and may be happening now as well), can drop off suddenly and quite sharply, leaving oil behind that may never be recovered.

2)      Saudi Arabia claims to have 260 billion barrels of reserves, but the real number is probably less than half of that.

3)      The Saudis damaged their oil fields by over-producing in the early 1970s and again after Iraq invaded Kuwait in 1990. That changed the subsurface pressure, creating huge water problems that will make it harder to recover oil.

4)      Congress had evidence in the 1970s that the Saudi oil fields had only about 30 years of sustained production left but kept it secret.

5)      There are no new large oil fields likely to be discovered in Saudi Arabia

6)      The Saudi’s are mining their oil in ways that Hubbert hadn’t anticipated. They’re using new technology, which depletes the oil sooner, which makes the decline rate steeper than what Hubbert and others calculated.

7)      We’ve used up the vast majority of the world’s high flow rate, high quality oil. We still have a lot of oil. But it’s heavy, gunky, dirty, sour, contaminated oil.  It doesn’t come out fast, and it’s very energy intensive to get out.

So not only do the Saudis probably have a lot less oil than they claim, but extraction could fall off precipitously due to poor management in the past and the use of new technology, which is depleting the oil sooner than it otherwise would have been.  Worse yet, what’s left is poor quality, difficult and expensive to refine oil that’s hard to get out.

Consequences of a decline in oil

When world oil production declines, all nations will be affected.  The major likely consequences are global depression and civil disorder as decline continues, starvation as agriculture is affected, and World War III over the remaining resources.  Wars have been fought over minerals throughout history (Youngquist 1997). Colin Campbell has written a global depletion protocol to try to prevent this from happening, but at this point most governments are not even aware of it, let alone trying to implement this plan (Heinberg 2006).

As time goes on, shortages will occur, triggered not only by declining oil supplies, refinery breakdowns, and hurricanes destroying oil infrastructure, but also from revolutions and terrorists blowing up oil refineries, pipelines, and oil tankers.

The USA is down to oil reserves that could power our country, at current rates of use, for four years.  This vast country, with limited train and mass transit systems, combined with massive dependence on vehicles to reach sprawling suburbs, makes the United States very vulnerable to oil shocks.

There are plans in place for rationing should shortages strike (Wendling 2005, IEA 2005), and there is room for demand destruction.  The U.S. rationing plan calls for agriculture to take what it needs off the top.  After that other critical agencies will get what they need.  Anything left over will be distributed to everyone else.

Natural Gas Depletion

Natural gas heats over half of all American homes and provides twenty percent of our electricity.  Natural gas is also used to make plastics, chemicals, fabric, carpets, packaging, and many other products. It is the feedstock and energy source used to create nitrogen fertilizers that grow up to four times more food than could be grown otherwise.  It’s also used to refine oil and tar sands (Darley 2004).

North America will face the depletion of natural gas within the next decades.  Natural gas extraction has a much steeper rate of decline than oil – current annual new well decline is 31% and half of the natural gas needed in 2012 is going to come from fields that haven’t even been discovered yet (EIA 2000). This problem is as serious as oil depletion.

Replacing fossil fuels with some other energy source

At one time, the Energy Returned on Energy Invested (EROI) for oil was at least 100 to 1.1   We are reaching the point where the EROI of oil will be 1 and no more drilling will take place (Boxell 2004). It was while the EROI of oil was high that most of our current infrastructure was built.

Evidence suggests that the EROI of corn ethanol is less than one, which means it takes more energy to make than you get out of it – an energy sink.

Pimentel and Patzek have shown that it takes 27 to 57 percent more fossil fuel energy to create ethanol or biodiesel than you get in the energy returned.  Worse yet, this is done at a tremendous environmental cost, since biofuel crops harm soil structure and remove the nutrients, deplete groundwater, pollute water with pesticides, insecticides, and herbicides, cause eutrophication of water via nitrogen runoff, increase soil erosion, and contribute to air pollution and global warming at the ethanol plant and when burned in cars (Pimentel et al 2005).

Even if the highest claim of a net energy for ethanol of 1.67 were true, a much greater EROI than .67 is needed to run civilization.   The 1 in the 1.67 is needed just to make the ethanol.  An EROI of .67 has 150 times less energy than oil when we started building American infrastructure.

Charles A. S. Hall, who has been studying net energy for decades, believes that you’d need an EROI of at least 5 to run civilization, because you need to include the energy to make the machines, mitigate environmental damage, feed and house the workers, and so on (Hall 2004).

For example, consider a windmill composed of steel and concrete.  A windmill farm in the Escalante desert, built to produce 5.55 TWh of power, would require 13.8 million pounds of aluminum, 2.8 trillion pounds of concrete, 639 billion pounds of steel, etc.  The wind farm would occupy over 189 square miles (Pacca et al 2002). Pacca & Horvath don’t give the capacity factor for these windmills, but an often used number is 30% (i.e. wind blows hard enough 30% of the time), so a 5.55 TWh wind farm might serve around 175,000 to 350,000 people, depending on the wind speed and how close people were to the windmills, since power is lost via transmission over long distances.

In 1992 such a wind farm would cost $200 million, which doesn’t include labor and maintenance costs, and would serve less than one percent of the United States population.  It would cost over $200,000,000,000 to build enough windmills to generate electrical power for everyone (though of course, you couldn’t, since not all areas have enough wind).  With energy prices many times higher now than in 1992, the cost would be far more expensive.

After fossil fuels are gone, the windmills must be able to generate enough energy to maintain themselves and build new windmills, including all of the equipment used to mine the metal and concrete components, forge metal into blades and towers, and build the trucks and roads that enable windmills to be delivered to their sites.  Windmill energy must also provide the energy to build and maintain the electric grid and storage battery infrastructure, and all of the people involved in the process.  Any extra energy could now be used to run civilization.

It’s often said that once oil goes to “x” dollars a barrel, alternative energy will become economically viable.  But this will never happen, because the alternative energy infrastructure is built with fossil-fuel inputs, so alternative energy sources will always cost more than oil. To even talk about energy using dollar figures makes no sense — you can’t stuff dollar bills down your gas tank.

Energy can be reduced to physics, to the laws of thermodynamics and other rules that the Big Bang bequeathed our universe.  Oil has been a free lunch, one that nature spent hundreds of millions of years making, reducing 196,000 pounds of plant matter into one gallon of gasoline – pure, unadulterated solar power that no alternative energy source but fusion could possibly hope to replace (Kruglinski 2004). Oil is also incredibly easy to use, ship, and store.

The number of scientists who insist that alternative energies can substitute for fossil fuels, and ignore or deny the basic laws of physics and thermodynamics is frightening.  It’s reminiscent of Lysenkoism.

United States Infrastructure

While the EROI of oil was high, we built a vast infrastructure to deliver clean water, treat sewage, built roads, bridges, dams, and so on.

Any non-fossil fuel type of energy will have a great deal of work just maintaining the existing infrastructure.  The American Society of Civil Engineers gave the following grades to our infrastructure (ASCE 2013).

  • B- Solid Waste
  • C+ Rail, Bridges
  • D+ Energy
  • D Dams, Drinking Water, Hazardous Waste, Wastewater, Roads, Transit
  • D- Levees

Consider just the drinking water infrastructure, the main reason our life spans have increased so much (Garrett 2001). In this century, all of the 600,000 miles of pipes delivering clean water to homes will need to be replaced.  Every component of the water system is aging.  The energy required to replace or maintain thousands of treatment plants, pumping stations, reservoirs and dams over the next century is staggering (USEPA 2002).

Useful Life Matrix

Clean Water (years, infrastructure)

  • 50 Treatment Plants – Concrete Structures
  • 15- 25 Treatment Plants – Mechanical & Electrical
  • 25 Force Mains
  • 50 Pumping Stations – Concrete Structures
  • 15  Pumping Stations – Mechanical & Electrical

Drinking Water

  • 50- 80 Reservoirs & Dams
  • 60- 70 Treatment Plants – Concrete Structures
  • 15– 25 Treatment Plants – Mechanical & Electrical
  • 65– 95 Trunk Mains
  • 60- 70 Pumping Stations – Concrete Structures
  • 25    Pumping Stations – Mechanical & Electrical
  • 65- 95  Distribution

And consider the energy required to deliver the water.  According to Allan Hoffman,  “Energy is required to lift water from depth in aquifers, pump water through canals and pipes, control water flow and treat waste water, and desalinate brackish or sea water. Globally, commercial energy consumed for delivering water is more than 26 Quads, 7% of total world consumption” (Hoffman 2004).

The fragility of global trade and infrastructure

Science fiction movies used to scare us with out-of-control robots bent on world destruction.  If there’s a runaway robot now, it’s global corporations doing what’s best for the shareholder rather than the citizens and nations of the world.  Pensions have been looted, health care benefits taken away, taxes avoided, and regulations ignored.

Risks are being taken that could bring down the global financial system.

One of the risks to global trade is due large computer and electronic companies using the same outsourcers for similar components from the same region — even the same place – such as an industrial park in Hsinchu, Taiwan.  The risk is a single source of failure.

Microprocessors are essential to the modern world

Billions of chips are created every year for a myriad of applications: in autos, airplanes, ATMs, air conditioners, calculators, cameras, cell phones, clocks, DVDs, machine tools, medical equipment, microwave ovens, office and industrial equipment, routers, security systems, thermostats, TVs, VCRs, washing machines – nearly all electrical devices.

So when an earthquake struck Taiwan in 1999, world markets were shaken. Willem Roelandts of Xilinx immediately knew this had the possibility of hurting the world economy.  “There is not an electronic product in the world that does not contain a Taiwanese component”, he said.

Even though the factories were fine, electrical and transportation systems weren’t, so production and delivery of components stopped, which caused assembly lines in the United States to halt as well.  Wall Street traders sold off electronic firms, especially Dell, HP, and Apple.

You wouldn’t think the United States would build microchip factories offshore in industries that were essential to its national and economic security.  But low wages are irresistible to corporations.  Also, many foreign countries are closer to sources of natural gas, which is declining at an alarming rate in North America.

According to Jack Gerard, president and CEO of the American Chemistry Council, “ “Natural gas is a raw material for compounds used in thousands of consumer products — from agriculture, telecommunications and automobiles to pharmaceuticals…and food packaging. More than 96 percent of all manufactured goods are directly touched by chemistry.  The industries that rely on chemistry together represent more than a quarter of the nation’s entire workforce. Unaffordable natural gas is driving away investment, crippling our manufacturing base, and reducing job opportunities. It is transferring to foreign countries the advanced research and technology desperately needed in order to compete on the world stage. In effect, our nation’s energy policy has become its de facto manufacturing and national-security policies as well (Gerard 2005).

Industries also like to locate factories where environmental regulations are less stringent.

The chemicals used to create computer parts have resulted in 29 superfund sites in Silicon Valley, the most concentrated number of superfund spots in America.  At the Advanced Micro Devices superfund site in Sunnyvale, California, chemicals are in the groundwater and soil that can cause death, cancer, brain and central nervous system damage, leukemia, anemia, convulsions, nausea, unconsciousness.  The zinc and copper at this site are toxic to plants, ruining what were once some of the best orchards in the world.

The need to go where costs are lowest is driven by the enormous amount of money it takes to build a mega-size wafer fabrication plants — nearly ten billion dollars (Skinner 1998).

Part of this amount is due to very high insurance costs.  In 1997, an Hsinchu Taiwan fabrication plant had a fire that caused $421 million dollars in smoke and water damage.

Business interruptions can cost a fabrication plant 20-30 million dollars in lost revenue.  For instance, a plant that had a four-hour long electricity outage had to spend the next four days recalibrating their equipment, resulting in a $5 million dollar loss. Insurance companies have responded with huge deductibles and capped the loss amounts (Buys 1998).

As unexpected energy shortages and outages grow more common in the future, this will wreak havoc on microprocessor production.

Outsourced products are delivered just-in-time to the factory assembly.   According to Barry C. Lynn, “Our corporations have built a global production system that is so complex, geared so tightly, and leveraged so finely, that a breakdown anywhere increasingly means a breakdown everywhere, much in the way that a small perturbation in the electricity grid in Ohio tripped the great North American blackout of August 2003” (Lynn 2005).

Less major blows to assembly lines have come from strikes, SARS, fires, explosions, and manufacturing mistakes, such as the ones that resulted in Chiron’s failure to deliver half of the American flu vaccine.   Fortunately, the impacts so far have been temporary and regional. But it’s not hard to imagine events that could result in worldwide disruptions leading to a global depression.

Energy shortages for instance.  Already many businesses in the chemical, agricultural, steel, glass, and other industries have failed or are in pain from high natural gas prices in America (AP 2004, Abbot 2004, Schneider 2004).  When enough key suppliers of infrastructure components fail, this will stop the downstream assembly line.  Suppliers might also go out of business because of economic failure in the manufacturing country, civil or regional wars, and extreme weather.

Despite the risk, single-sourcing occurs because cutting costs is how you stay in business, so the cheapest supplier wins the race to the bottom.  Corporations have gone cuckoo with outsourcing; letting suppliers located in potentially shaky political and economic countries hatch their nest eggs.

When the fledglings hatch they often fly on Fed Ex, which is so reliable it seems as if the supplier were on the other side of town instead of across the world.  But the airline industry is reeling from higher energy prices, so it’s possible that the intricate, just-in-time, high-speed aircraft delivery of electronic gear will shift to ships, a much slower, less predictable way to deliver cargo “just-in-time”.

Most products traded globally travel by sea.  Over 50,000 large ships carry 80 percent of the worlds’ cargo. Shipping faces critical challenges in the future.

Oil and LNG tankers are increasingly failing from corrosion. Over 2400 tankers split up or nearly did so from 1995 to 2001 according to the International Association of Independent Tanker Owners (Martin 2002).

Another hazard to shipping is piracy or terrorism. According to Gal Luft, executive director of the Institute for the Analysis of Global Security (IAGS), and Anne Korin, director of policy and strategic planning at IAGS and editor of Energy Security (Luft 2004):

  • The number of pirate attacks on ships has tripled in the past decade.  In 2003, there were 445 attacks. 92 seafarers were killed, and 359 assaulted and taken hostage, in 19 hijackings and 311 boardings.
  • Three-quarters of the globe is covered in water that is thinly policed.
  • Pirates are often trained fighters armed with automatic weapons, antitank missiles and grenades. Most of the world’s oil and gas is shipped through the world’s most piracy-infested waters.  Piracy is becoming a tactic of terrorists, who see it as a lucrative source of revenue. They’ve attacked tankers near Iraq, Nigeria, Saudi Arabia, and Yemen.
  • 60 percent of oil is shipped in 4,000 tankers passing through bottlenecks where they’re vulnerable to attack.  If a tanker were set on fire at one of these vulnerable points, the sea-lanes would be blocked.
  • Many shipping companies don’t report piracy lest their insurance premiums go up, but what is reported amounts to over 16 billion dollars per year.

Terrorism is affecting the worlds’ energy infrastructure. U.S. Energy Secretary Spencer Abraham has repeatedly warned that “terrorists are looking for opportunities to impact the world economy” by targeting energy infrastructure. Nigeria, Columbia, and Iraq have seen many attacks in the past few years.  There have been 469 attacks on oil infrastructure and personnel in Iraq from June 2003 to 2008 (IAGS 2008).

Trading Partners

Trading partners matter.  Strategically, it’s probably not a great idea to partner with China because of their bloody history, economic booms and busts, and a landscape so environmentally devastated millions of Chinese are on the brink of starvation.

But it’s corporations that are now making strategic decisions about what’s best long-term for U.S. citizens based on how profitable next quarter will be.  The United States relationship with China began with Motorola, and Wal-Mart consummated the marriage.

China is on the verge of being unable to feed itself. More than 900 square miles of land degrade into desert every year while even larger areas are losing their productivity (Eckholm 2000).  The soils are becoming acidic and lifeless, making the crops vulnerable to fungal attacks. Worse yet, this shift has caused grain yields to fall by 20% (Pearce 2004).

Water is growing scarce for farmers because cities usually win the rights to it. Aquifers are depleting and irrigation wells are drying up, forcing farmers to abandon their land.

According to Lester Brown of World Watch, “The cheap food of the last century may soon be history.  China will soon have to buy grain on the world market, and given their 150-billion trade surplus, will be competing with Americans for food, at a time when the USA is also losing cropland to aquifer depletion and soil erosion” (Brown 2004).

Much of the country is an environmental disaster.  The Gobi desert grew 20,000 square miles in five years and is now within 150 miles of Beijing.  This has been brought on by over-farming, over-grazing, and destruction of forests.  The dust from this desert is starting to affect the whole world, and contains arsenic, cadmium, and lead (French 2002).

We’ve become so linked to China economically that their frequent booms and bus could do the same to our economy.  Many industries have China to thank for their good times, especially shipping lines, which are hauling enormous amounts of oil, 150 million tons of iron ore, coal, and other raw materials to China, and bringing back finished goods like electronics, furniture, and clothing.

China has surpassed the United states in the market for cell phones and color TV’s, and is on their way to outdoing us in buying PC’s and soon, perhaps, energy.

There are almost 120 boys for each 100 girls being born in China, due to the one-child policy leading parents to prefer boys to girls.   Historically, this skewed ratio has meant big trouble, and one of the ways societies coped was by starting wars.

Women are being kidnapped and sold as brides. From 2001 to 2003 China’s police freed more than 42,000 kidnapped women and children.  And it’s only likely to get worse; one estimate puts the number of bachelors over the next decade at 40 million.

This could pose a threat to China’s stability according to Valerie Hudson and Andrea Den Boer, authors of “Security Implications of Asia’s Surplus Male Population”, which cites two Manchu Dynasty rebellions in areas that were disproportionately male.  They believe that young adult men unlikely to find wives are “much more prone to attempt to improve their situation through violent and criminal behavior in a strategy of coalitional aggression.”

Whether China dissolves in internal chaos, kicked off by hunger and unhappy bachelors, or explodes outward militarily as resources grow scarce, remains to be seen.  But given China’s violent history, it’s a sure bet there’s a conflagration ahead (Wikipedia 2015).

Stephen LeBlanc, Harvard archeologist, believes that throughout most of history we have been engaged in constant battles.  When trying to find out why war was so prevalent, he assumed people were fighting for real reasons, and he discovered that the fights were always over scarce resources, usually food and often women.

He has evidence that we have never been able to control our population growth, which inevitably resulted in over exploitation of the environment, as far back in time as you go.

The consequence of over-exploitation is scarce resources, and that usually leads to war.

LeBlanc concludes: “Humans starve only when there are no other choices. One of those choices is to attempt to take either food, or food-producing land, from someone else. People do perceive resource stress before they are starving. If no state or central authority is there to stop them, they will fight before the situation gets hopeless” (LeBlanc 2003).

Jared Diamond looks at the recent example of the Rwandan genocide in “Collapse” (Diamond 2006).  Although most people think this was an ethnic struggle between the majority Hutu and ruling Tutsi, that’s because most people understand the world in terms of ethnic conflict. Since there were areas where Hutu killed Hutu, Diamond concludes that the real reason for the slaughter was for ecological reasons: “Look at the land: steep hills farmed right up to the crests, without any protective terracing; rivers thick with mud from erosion; extreme deforestation leading to irregular rainfall and famine; staggeringly high population densities; the exhaustion of the topsoil; falling per-capita food production. This was a society on the brink of ecological disaster, and if there is anything that is clear from the study of such societies it is that they inevitably descend into genocidal chaos”.

If LeBlanc and Diamond are correct about hunger resulting in battles, then we’re in for a rough time, as oil and natural gas grow scarcer.  Food, from planting, fertilizing, harvesting, and distribution, is utterly dependant upon fossil fuels in the United States.

How America handles a declining standard of living, given our addiction to comfort and super-sized meals, with over half of Americans owning guns, and 30,000 people killed with guns in 2002 (NCIPC 2002), remains to be seen.

Continued global trade at current levels cannot be sustained as energy declines.  At some point global trade will lessen due to a combination of declining fossil fuels, piracy, terrorism, energy shocks, pandemics, natural disasters, political turmoil, global depression, and a shortage of large, non-oil based vessels.

Global trade will not disappear, since moving freight over water is very efficient, but there will be several discontinuities as declining energy forces us to roll backwards though history.

Most cargo is shipped on enormous container vessels that can be over 1100 feet long with ten thousand containers stacked many stories high.

The first discontinuity will come when we have to retrofit ships to run on coal, and set up coal stations and tenders all over the world.

The second discontinuity will occur when coal gets scarce and container ships are moved by wind power (if this is even possible), with liquid fossil fuel only used when entering and leaving ports.  A further step down will happen when it’s too energy-intensive to keep harbors dredged deep enough accommodate large container ships.  It’s already very tricky getting these large ships into port, a local pilot is brought in and complex computer systems are used to delicately park these gargantuan ships along the wharf (dIBBLE 2005).

These huge ships would have to remain offshore and unloaded to smaller ships, if that is possible, since they weren’t designed for this.

The third discontinuity will come when containerization can no longer be supported due to lack of fuel and/or electricity for cranes, trucks, and trains.  Containerization revolutionized the amount of cargo and the swiftness with which it could be loaded and delivered from origin to destination by orders of magnitude over earlier forms of transportation.

The final discontinuity will come when ships need to be built from wood, because the remaining mineral ore is too low quality and energy-intensive to process, and when we can no longer recycle the rusted and dispersed iron and steel.

The Fragility of Microprocessors

I work in the computer industry as a systems architect/engineer.  My father got in on the ground floor, programming computers with wires before there were even punch cards.   As far as I could tell, his job was to draw squares, circles, and triangles and connect them with arrows.  I used to fill the flow charts in with crayons when I was younger.

I took an introductory course to find out what Dad had been doing, and was hooked.  I couldn’t believe you could get paid to solve intricate and interesting puzzles.  I abandoned my plans to get a PhD in molecular biology and started working at EDS.

I think computers are the most amazing achievement of mankind.  I especially like being in touch with family, friends, and new acquaintances from around the world with common interests.

The first computer, the ENIAC, built in 1940, took up 1500 square feet.  The same floor space now could contain 1.4 million microchips, each with orders of magnitude more computing power.  A car now has more computing power than the first lunar spacecraft.

Microchip fabrication (Van Zant 2004, Quirk 2001)

Creating a chip begins by cutting a thin 12 inch slice, called a wafer, from a 99.9999999% pure silicon crystal, one of the purest materials on earth.  Wafers require such a high degree of perfection that even a missing atom can cause unwanted current leakage and other problems in manufacturing later on.  This is the platform that about 5000 computer chips will be built on. Each chip will contain millions of transistors, capacitors, diodes, and resistors built by punching and filling in holes in more layers than a Queen’s wedding cake.


Particles 500 times smaller than a human hair can cause defects in microchips. The more particles that get on a wafer, the greater the chance there is of a killer defect. Some particles are worse than others — a single grain of salt could ruin all the chips on a wafer.  Sodium can travel through layers even faster than stray bits of metal.  Particles that outright kill a chip are caught during the testing phase at the factory.  Sometimes only 20% make to the end.  The traveling particles are insidious, and can cause a chip to malfunction, perform poorly, or die later on (hopefully before your warranty expires).  Consumer reports recommends not even trying to repair a personal computer after four years, and in the two to four year range it’s a tossup whether to repair or buy a new one.

Typical city air has 5 million particles per cubic foot.  There are processes that require a maximum of 1 particle per square cubic foot.

People are among the worst offenders, as far as particle generation goes.  If you walk at a good clip, you emit 7.5 million particles per minute.  Even sitting still, you are still emitting particles.  A smoker is a particle-emitting dragon long after the cigarette, and a sneezing worker is even worse, a veritable Krakatoa.

City water is not pure enough to be used — it’s full of bacteria, minerals, particulates, and other junk.  To make city water clean enough requires many filters, UV-light, and other water treatments.  Some fabrication plants use millions of gallons of water a day, requiring a huge investment in water processing and delivery systems.

Microchip fabrication is primarily a chemical process, requiring ultra-clean 99.9999% chemicals and 99.9999999% gases.   About one in five steps use water or chemicals to clean the wafers or prepare their surface for the next layer.

Firemen practically need a chemical engineering degree to inspect and fight fires in a chip fabrication plant.   During a fire, they risk being exposed to volatile, flammable, or combustible solvents, and chemicals like arsine, used in chemical warfare.

The chips also require humidity to be just right.  If the humidity is too high, the wafers accumulate moisture, and the layers won’t stick.  Too dry and static electricity will suck particles out of the air and practically glue them to the surface, they’re so hard to remove.

So it shouldn’t surprise you that it costs over 3 billion dollars to build a clean room. The inside is composed of non-shedding materials, especially stainless steel. Floors have sticky mats to pull dirt off of operators’ shoes.  Pens, notebooks, tools, and mops – everything is built of material that sheds as few particles as possible, but even so, equipment particles cause a third of the contamination.

How chips are made

Wafers move from workstation to workstation and have different operations performed on them at each one.  Wafer fabrication for a chip might involve 450 processes with operations that overall take several thousand individual steps. The machines that make this all happen include high-temperature diffusion furnaces, wet cleaning stations, dry plasma etchers, ion implanters, rapid thermal processors, vacuum pumps, fast flow controllers, residual gas analyzers, plasma glow dischargers, vertical furnaces, optical pyrometers, etc.

If you were shrunk to chip size and tied to a wafer, you’d go through the car wash from hell.  You’ll be moved along by robotic wafer handlers from one machine to the next, where you’d be layered with different materials, centrifuged, electro-polished, dyed, scraped, heated to 1,800 F, ultrasonically agitated, sputtered, doped, hard baked, dipped in toxic chemical baths, irradiated, blasted with ultrasonic energy, spray-cleaned, dry-cleaned, scrubbed, micro-waved, x-rayed, shot with metal, etched, and probed.

At various points, the “Survivor” show comes on.  Chips are examined at an atomic level for defects, and their electrical functioning tested. They’re usually thrown out if anything is wrong, since most mistakes can’t be fixed.

There are many problems that can cause a chip to fail besides contamination. The wafer must be perfectly flat in structure and while it goes through the workstations.  If the wafer were 10,000 feet high, you’d see bumps or holes no higher than 2 inches – more than that and the layering is thrown off.   If the wrong step was performed after 3,841 correctly performed steps, the chip was under or overheated, the layer didn’t fully stick, was improperly aligned before the next layer was added, or a chemical misapplied, the chip is thrown out.  It’s amazing any chips make it out the door.

After your makeover, you’d emerge in a designer outfit composed of up to 25 layers embedded with millions of transistors, diodes, and resistors.  You’ll find yourself “best in show” at tattoo competitions and irresistible to Terminator fans.

The Case for collapse starting sooner than later

Jared Diamond lists five main factors for the collapse of civilization (Diamond 2006). All five are evident. The first two reasons, collapse from environmental reasons and climate change are so evident they require no further comment.

The third factor is not being able to adapt to new conditions.  Dmitry Orlov makes a good case for the eventual collapse in the United States being much harder than the recent collapse in the former Soviet Union due to our cultural weaknesses (Orlov 2005). Ecologists believe that we needed to have started adapting to the decline of energy in the 1970’s by reducing our population and encouraging small family farms to get people back to the land.

The fourth reason for collapse is “relations with hostile neighbors”.  There is reason to believe sleeper Jihad cells lie in wait of an opportunity to blow up key pieces of infrastructure in America.  Russia, China, and Europe may unite against the U.S. to prevent America from taking the lions’ share of the remaining oil.

On the fifth factor, relations with friendly nation, Diamond said: “Almost all societies depend in part upon trade with neighboring friendly societies, and if one of those friendly societies itself runs into environmental problems and collapses, that collapse may then drag down their trade partners. It’s something that interests us today, given that we are dependent for oil upon imports from countries that have little political stability in fragile environments”.

Diamond’s “loss of trading partners” factor is another reason computers won’t survive PetroCollapse.  As global shipping, factories, and countries have a hard time keeping the lights on; computers will stop being made as supply chains break down.  If even one of the dozens of types of single-sourced equipment or pure chemical suppliers goes out of business, the assembly line stops.

Andrew Gould, CEO of Schlumberger, said of the oil decline that “An accurate average decline rate is hard to estimate, but an overall figure of 8% is not an unreasonable assumption” (Gould 2005).

Matt Simmons also believes that an 8% rate of decline is possible, given how Saudi Arabia’s fields were mismanaged, the use of technology to extract the oil sooner than it would have otherwise been pumped, other super giant oil fields having depleted rapidly after their peak, and the likelihood that Saudi oil reserves are probably half of what is reported.

The decline after peak might initially be low, buying a few years of time, but if it does reach 8% per year, world oil extraction would decline by almost half in eight years.   That is likely to lead to the collapse of civilization, because there is too little time to adapt.

Preservation of Knowledge

A project to preserve knowledge may be unable to continue in an unstable society beset with power outages, hunger, and crime. Once rationing and shortages begin, agriculture and other essential services will receive the most energy.   Scientists will be unemployed.  It is likely that resource wars will erupt all over the globe, so the military will be taking a large portion of the dwindling energy resources as well (Roberts 2004, Scully 2004, Luft 2004, Glain 2004, Kunstlr 2005, Gordon 2005, McNamara 2005).

The time to begin is now, before we begin the inexorable retreat to wood as civilizations’ main energy source.

We’ve reached the point where we need to be concerned about the preservation of knowledge.  This cannot be done with computers, which are the least likely component of all to survive long-term, but this is the main plan for storing knowledge at institutions dedicated to this issue.

Computers are the top cards in the civilization house of cards.  Knock out any below and it all crumbles.  Computers have too many complex, energy intensive inputs and dependencies (Hawken 1999, Shaw 2004 2005, Boberg 2000).

How can it be done?

We may be able to cannibalize computers for parts to keep some machines running, but eventually all the knowledge stored in computers will be unavailable.  Not just because some key material to make computers is missing, such as a rare earth metal, but also because the electric grid very likely can’t be made 100% renewable, possibly no more than 56% renewable, because wind and solar are so intermittent, unpredictable, and destabilizing that operators won’t be able to keep supply and demand in exact balance.

Although archival paper and microfiche can last for five hundred years when kept at ideal temperatures and humidity, power outages will make it impossible to maintain them for that long.  If trees run short, people may burn books to cook with, and books in abandoned houses will quickly decay.

From a practical standpoint, paper is the best bet for most people.  Here is what Walter Isaacson had to say at the Goldsmith Awards ceremony about this.  He told the audience that Leonardo DaVinci left more than 7,200 notebook pages of sketches and ideas.  They’re very easy to access, unlike the emails Steve Jobs sent in the 1990’s that he couldn’t retrieve, not even with the help of technical staff at Apple from the NeXT computer.   And what about CompuServe emails and WordPerfect documents?  Paul Sagan,who worked on the Riptide project at the Kennedy School told me there are problems with the digital age – it doesn’t give us the real foundations and information we need.  When I consider paper, “I realize what a good technology paper actually is.  It’s really good at the storage and distribution and retrieval of information.  It’s got an incredible battery life.  It doesn’t have to have backwards compatible operation systems. It just works.” (Isaacson)

Justin Fox, a columnist at Bloomberg, estimates that about 5 exabytes of information were written down from the beginning of civilization through 2003 (a byte is 1 character, an Exabyte is 1,000,000,000,000,000,000 bytes.  According to Eric Schmidt at Google, now we create 5 exabytes every 2 days due to the internet and digitizing everything.

Fox writes “I’m starting to worry, though, about the possibility of a new information Dark Age. When I asked a university librarian recently the best way to preserve some interesting emails I had, she said I should print them out on paper and put them in a box.  One of the strengths of paper as a data-storage technology is that it can preserve information that no one really intends to preserve. To someone with embarrassing photos on Facebook, it can seem as if the Internet does the same thing. But Facebook may be gone in a few decades, whereas paper has proved itself over centuries. Printing has the added benefit of mass redundancy – even if most copies of a book or old newspaper are destroyed, a few may live on in attics or libraries” (Fox).

But if it is possible to preserve knowledge longer than paper will last, we ought to try.  Perhaps words can be printed on non-corrosive metals or other extremely durable substances.

I’m sorry I don’t have more technical and specific proposals.  I tried!  I’ve written soil scientists, ecologists, biofuel scientists, and petroleum scientists, among other disciplines, to obtain information for writing posts at energyskeptic and my book “When Trucks Stop Running”. A large percent of them replied and continue to do so.

But not one of the hundreds of material scientists I wrote about preserving knowledge wrote me back, not even to suggest someone else.  I also printed this essay out in 2005 and put it in Steven Chu’s mailbox (he lived just a few doors away).  At the time he was the director of Lawrence Berkeley Laboratory, and in my cover letter I suggested he fund research on preserving knowledge in the materials science department.  He could this because National Lab directors have funds they can give out.  Of course I didn’t expect to hear back from him, and of course he never funded such research.

Nor did he fund a project proposed in 2006 by Tad Patzek, former professor of civil and environmental engineering at Lawrence Berkeley National Laboratory (LBNL) who proposed a study on energy returned on invested (EROI).  Clearly an EROI analysis would help society and policy makers choose the best options of which energy resources to invest in.  So Patzek proposed a broad EROI study of a range of energy sources. But he was unable to get funding “to compare BTU’s to BTU’s for apple to apple comparisons and consistent thermodynamic descriptions of all major energy capture schemes.” He concluded that this might be due to “no one wanting to know they may be working on a senseless project, such as industrial hydrogen from algae.”

It seems a shame that we aren’t making any attempt to preserve knowledge for millennia, after all, we once put a disk on a space probe to explain humanity to potential aliens, why can’t we do that for our descendants?

Clearly not everything in print can or should be saved.  Priority should be given to information that would be useful for a society far simpler than ours.  And interesting books on history, anthropology, the best literature, and so on for a world without TV’s, radio, or computers.

We should also leave our descendants with information they can be amazed by. Especially a list of the millions of species we drove extinct, and pictures of as many of them as possible to preserve awareness of the wonderful life that used to exist before 7+ billion humans took over most of the planet. We owe it to them.  It’s the least we could do, since it is highly unlikely we’ll clean up our toxic nuclear, mining, and industrial waste and are a leaving them climate changed world where crazy weather will make it hard to grow crops reliably, among other sins.

If we can spend billions on microchip factories that are out-of-date within two years, surely we have the resources to save some useful knowledge and music for our descendants.

We need to find better materials than paper and clay tablets to preserve knowledge.  Someday there will be a new renaissance.

Maybe it’s as simple as converting Coca-cola factories from making soda cans to printing aluminum books.

17 Responses to Preservation of Knowledge

  1. Brian Dunn says:

    Alice, Alice – what perverse dark fun it is to read what you’ve written here! I remember many days and nights in Unit One and its cultural environs as we all faced the onset of the 1973-74 oil shocks and wondered what it all meant, with the likes of Bob Olsen (locally) and Stewart Brand, Robert Heilbroner, Amory Lovins and Hazel Henderson (imported) fanning the flames of futurism amid dark forebodings. I am VERY grateful for your work in assembling and overviewing the above. Steward Brand’s turnaround on nuclear power (illustrated in his TED talk on “Whole Earth Discipline”) has been very impressive, but in the wake of Fukushima I wonder about the hurdles even the sensible work will face. The most intriguing development I remember him mentioning was the creation of self-contained electricity-generating “micronukes”, appliances about the size of a raised-roof minivan, if I remember correctly, which could be manufactured as a commodity under optimal conditions with minimal risks….gotta go, thanks again!

  2. Laura Geiger says:

    Thank you for all the work you have done to assemble and clearly present this information. Another way to store knowledge is through oral traditions (storytelling). Not sure if that would work for “how to build a nuclear reactor” or even “how to make a pencil”. I have some experience making pottery; even preserving knowledge by carving it on clay would consume a lot of energy, since the clay would need to be fired to make it durable. And where to start? What is the most important piece of knowledge to preserve on the first tile that I carve?

  3. Cassie says:

    “oh, ye of little faith” : Nature will decide what is useful to our ascendants (see that notion of progress there?) and all our connivances will be of immense personal comfort to us as our eyes close, as we pull the blanket of soft darkness over our heads, snuggle in, and drop off into the slumber of extinction.

    This does not trivialize this process, but do not imagine that we can define or imagine the needs of those in circumstances unknowable.

    I suspect our shards and what books or things remain – all clues that there are indeed mysteries – will help those who follow us sufficiently to meet their needs.

    The biggest needs will be for some aid to our personal losses – our current mild pandemics and mild disasters involve large personal and economic loss. Big changes imply big problems, as the effects of population overshoot and loss of available resources cross, slowly at first and then rather too fast for peace.

    But note that species either take care of themselves as a whole or they do not. The components’ fates make little difference except to themselves.

    My spouse says I seem to have lost some of my innate cheery optimism. I cannot begin to tell her how “concerned” I feel right now that we are at the cusp of the really loooong slide, and it is hard to see the shape of the slide in the dark. I hear unpleasant sounds though.

    There is no need to recite the litany; we all know what may well crash around us now, but our blind drive to find a way out even frames our language and syntax, and we hope we are wrong.

    I hope I am wrong. I think I am right, though.
    Cognitive dissonance, eh? Schizmogenesis? Survival instincts or culturally derived self-deception?

    However. Even the cold bite in the air is a pleasure, and anticipating loss for too long will make you feel the loss before it occurs.

    All vision is confusingly wrong looking forward and always right looking back.

  4. tim bastable says:

    Hi This isn’t a comment as such – just that i can see no way to e-mail you or a comment space under the entry that interests me – I’m trying to get some sort of EROEI on pelleted straw – proposed fuel for a bio-fuel power plant close to where I live in Norfolk in England. I’m someone who’s been into sustainability for most of my adult life – and I’m in my 60’s now so that’s quite a while, and I’ve learnt enough to know which “green ” proposals have merit and which are questionable – bio fuels have never been high on the list and I enjoyed your take on them in “Peak soil” I’ve similar reservations and concerns about the need to retain an organic component to the soil structure.

    However what I’m really interested in is the energy chain of harvesting, processing and transporting straw – it’s not a bad on farm fuel but I can’t imagine it has much viability in any situation where it creates an energy cost – any leads to information that quantifies this would be helpful.

    Hope you can help


    • energyskeptic says:

      Charles Hall, Tad Patzek and others who’ve done excellent work on EROEI have had to do so with their own money for the most part. There’s little to no funding for this work. For example, Patzek once wrote me “Right now Steven Chu decided not to fund my Laboratory Directed Research and Development (at Lawrence Berkeley Laboratory) project whose goal it would have been to arrive at a consistent thermodynamic description of all major energy capture schemes bio and fossil, so that we compare apples with apples. What I did not appreciate is that no one wants to know that they may be working on a senseless project, such as industrial hydrogen from algae. I despair seeing the rapid corruption and sovietization of American science (without the Soviet strengths in basic sciences), but can do little about it. I am currently too hot to be touched, having run afoul twice of the current sorry Secretary of Energy and Secretary of Agriculture. Perhaps it is time for me to move back to Europe. It is not easy to get funded on the subjects I have proposed. I have been severely criticized by the Secretary of Energy, second time at LBNL. After that Steven Chu distanced himself from me. In fact, my LDRD proposal to develop the comprehensive thermodynamic language to talk about the different energy resources was just not funded. My only hope is private funding here and abroad, but there is much work to do to establish contacts and credibility.”

      So I doubt there’s funding for straw pellets EROEI. It is indirectly implied in biofuel and wood/biomass combustion plants studies at DOE, NREL, the California Energy Commission, etc., that the maximum distance is 40 to 50 miles because beyond that the diesel fuel to go empty from biofuel plant to farm and back with lightweight material or biomass heavy with water if it isn’t gathered before the first storms. It’s also implied because these studies mention that this short distance doesn’t allow these plants to be built to the proper economy of scale (so how can it have a positive EROI?).

  5. Jeremy Grimm says:

    I recall seeing an announcement in a design magazine (Design News?) about an IBM process for etching microfiche records onto stainless steel. I think the time frame was right around 2008-2009 roughly the time when the Federal government started the push for electronic medical records initiatives. The product disappeared after that one announcement and I haven’t been able to locate the reference I remember or any other reference since.

  6. richard says:

    Some internal hard disks are now quoting MTBF times of over 2 million hours. I’d suggest that some way will be found to preserve knowledge over at least that timespan.

    What to preserve, now that’s a more difficult question.

    How to compile an OS kernel from the basics, might be a good start. Maybe right below methods of forecasting the future.

    • energyskeptic says:

      Declining oil will cause a financial depression, businesses will go bankrupt, supply chains will break, so who will make hard disks? The electric grid is 90% fossil fuel dependent and it is is likely that without energy storage, wind and solar can not contribute more than 30-50% of power, and we don’t have energy storage (see the posts about that under the energy menu item). So what will power the remaining internal hard disks? I agree that what books to preserve is difficult. I hope that people will buy hard copies of the books I recommend, and perhaps put them in gallon freezer bags, or in arid climates, bury them in waterproof chests to keep the Religious fundamentalists and right-wing demagogues who will arise in the chaos of decline to keepm them from burning them, since knowledge is a threat to religious and political systems who thrive best when people are kept ignorant.

    As we don´t know the level of technology, resources or energy available, so, preservation of knowledge should start from the basics;

    Diagrams (pictures) of: a masonry heater, Biochar production and/or Activated Charcoal (Activated Charcoal has many uses) production, water filtration using that charcoal, rain water harvesting in aquifers through bawris, a well to reach that aquifer, a persian water wheel, a windmill (preferably ancient Greek Mykonos-style with sails), a wooden watertank, irrigation channels to crop fields, an Iron Works, Ethanol brewery, a steam engine, a Roman Hypocaust bath, a Brick kiln, a Woodmill, cement and concrete production, and a Chinese Dragon kiln for pottery.

    One of the most crucial classes of chemicals throughout history has been alkalis like potash (potassium carbonate) and soda (sodium carbonate), as these are needed in making glass, paper and soap. Potash can be simply extracted from the ashes of a wood fire by soaking water through them. Discard the insoluble minerals that settle on the bottom, and then recover the dissolved potash by evaporating away the water. Soda is made in the same way, from burning seaweed.

    And finally with glass production capabilities, a diagram of an earth sheltered vertical green house, that incorporates in its design a lot of those diagrams mentioned earlier. Including chicken coops, rabbit coops and hydroponics.

    One way of preserving knowledge would be to have a number of those earth sheltered vertical greenhouses with masonry heaters, ethanol breweries and Roman Hypocaust baths, with instruction diagrams etched on metal plates attached. Such buildings would be too valuable for anybody to destroy on purpose.

    thanks a lot Alice for your excellent review!
    As a former atomic physics scientist, I fully agree to your list of predicaments. I bailed out of science, since a while ago, I did not see any point in it anymore, my writings will be amongst the literature soon forgotten. I worked different jobs over the past years mostly as a high-tec engineer; sounds ludicrous, but that’s all I learned and I have to pay the bills for preparing a prepper compound. One of those jobs was in a company that is the world leader in archiving systems. Btw. I created the OS16000 line, but the product of interest here is the “ArchiveWriter OP 600 / 700 HR” It’s the ONLY device on sale world-wide that is designed to write HighRes Computer screenshots on microfilm. It’s on offer already quite many years, because all government archives here in Europe use silver-coated, grayscale microfilm to store document pages on microfilm in barrels underground. The abovementioned device can handle also colored images by writing 4 images (BW, Red, Green, Blue) separately. It also writes markers on the side to wind fastforward through a roll of film more easily with the readers available at Zeutschel too. It requires in extreme cases just a magnifying lens to read documents on that microfilm, the compression ratio was for that very reason chosen not too high. They claim, microfilm in that storage is virtually permanent, but I’m not an expert on this. But there are 2 problems: we were running out of suppliers for the microfilm itself, and once the flow of oil stops, microfilm will become unavailable. And how to dig through thousands of steel drums full of steel boxes with thousands of kilometers of microfilm without electronic readers but by hand remains a mystery to me. At least they exist and there are tables of contents on microfilm, listing all the microfilm rolls down to the position of the desired document image on the roll (in mm from the start marker). But I guess these archives will become forgotten for another not so surprising reason: who will care for them, if the rest of mankind struggles to survive? So despite of being proud of my old employer: I’ll stick to paper books myself, and try to explain and excuse to my kids, once they’re old enough, the old fashioned way: talking to them sitting around a camp fire.
    keep up the good work on this great page,
    cheers, Chris from Germany

      Thank you for your great reply! I suggested printing books on aluminum cans in this article, but your bringing up the retrieval issue is huge – even if you preserve knowledge, how will anyone find it?

      • chris says:

        yes, indeed, aluminum books would work out better, but I’d like to add another detail, not trying to make you feel bad, but: what does it take to understand what those books are about? Even if you know how to read the symbols: I still have a collection of books from my studies, e.g. Landau-Lifschitz: “course of theoretical physics” including general relativity. It takes years of studies just to grasp the concepts explained in it, and I guess, books about biology, chemistry, medicine, engineering, and so on will be facing the same problem: it takes prior education just to understand and apply the contents. Education and science are the highest achievements of civilizations, as it requires huge rerouting of resources to nourish and equip people devoted to knowledge: scientists, researchers, teachers, librarians and so forth. Will there be a future, where new civilization are able to afford such people to be fed by the small harvest of hard-working peasants? Open to debate…

        • energyskeptic says:

          Yes, what books to try to save is important. Nearly all knowledge now is only available electronically at universities in journals and online books. Poof, it will vanish. So I imagined college textbooks as one easy way to capture what we know about the world. In the future there will only be a few rich, elite people with the luxury to learn to read and write, though ironically now that people can do so, they for the most part choose not to, and if a book is read, it’s fiction. Without an organized effort I expect that whatever survives will be the random books on people’s shelves, one hell of a lot of Steven King and other popular writers. Starting at the end of the Roman Empire, Christians spent the next six centuries smashing, burning, looting, and taking down pagan temples, entering people’s homes and taking their books and paintings, so I expect that the Bible Belt with have no books but bibles at some point.

    This is a really informative and fascinating read,but I am wondering why do we need to preserve all the knowledge that we have today if the means of using that knowledge(namely energy) will not be with us in the future.

    For example: Making a microchip is a very complex and difficult process as you have mentioned. In the distant future it will be impossible to gather the minerals needed to make the chip or have the energy to power it,so what is the point of having the knowledge of chip fabrication.

    Applying this reasoning to other things we see around us today it becomes obvious that most of the knowledge we have accumulated is dependent on fossil fuels to be useful.(eg: MRI,Aircraft,Pharmaceuticals)

    There are a few things however which are useful regardless of fossil fuels.
    But this amount of knowledge is very small and can be put onto a few books and passed on from generation to generation.There are books that date back to thousands of years which are with us.The most famous one would be Euclid’s Elements.

    This site has a great collection of such books.

    Wouldn’t it be enough if we simply preserve the books mentioned above and pass them on from generation to generation?

    • energyskeptic says:

      I agree not all information will be useful, but it would be great if libraries took this challenge on and had criteria, such as technology that doesn’t require fossil fuels, etc. Maybe high school or college textbooks in various topics. I’d like future scientists and historians to know what went on in our time, even if they can’t replicate it, and so society doesn’t become some sort of cargo cult, and religious fanatics don’t burn every book they can find as they did during the Roman empire (see The Darkening Age. The Christian Destruction of the Classical World by C. Nixey for the full horror of this. The pagans were upset about the destruction of tens of thousands of their temples, libraries, and more than we’ll ever know was lost, and the absolute lack of a sense of humor in Christian writings and the Christians they knew personally or who spoke for the church. That still hasn’t changed!)

      • Kiran says:

        I agree that the lack of scientific knowledge will allow superstitious beliefs to fester and push us back to dark ages.

        I feel as though there are two ways to view the oncoming crisis – one is short term outlook and other is the long term one.

        In the short term I think we have some time.The global oil production (all liquids) is around 95 million barrels.But all we need is around 30-35 million barrels to feed the people all over the world and have a spartan economy with the absolute basics.This might be possible since we might still be producing that amount in 2050. Of course that would require energy gluttons like U.S to share the world’s oil equitably with the rest of the world.As unlikely as it is,if done it does buy us time till the end of century.

        The long term view is much more bleak. I had been to an (surface mined)Iron ore mine recently.I enquired about the stripping ratio and overburden.It seems as though with the exception of the float ore which is formed at the surface,rest of the ore is out of the reach of manual mining.So after a few thousand years
        when all the metals on the surface that we have extracted have rusted away we will have to go back to stone age.There may be a few regions around the world who will be able to enter a brief iron age or bronze age which may last for a few centuries but for most of the world it is stone age.

        Looking at things from this perspective what kind of information storage system would be viable?
        Maybe if we select the most important information we could carve it into stone tablets. I am curious to hear your thoughts on this.

        • energyskeptic says:

          I wish I knew how to preserve knowledge long term. Former energy secretary Steven Chu lived a couple of doors down from me, and at a block party I asked him if some material scientists at the Lawrence Berkeley National Lab couldn’t work on that. He probably thought I was nuts… I’ve written dozens of material scientists and gotten no reply, whereas when I wrote peak soil and wrote 50 soil scientists, nearly all of them wrote me back. I’ve heard that Europe has a project going, I need to do a post on what I know about that so far.

          The 500 giant oil fields, that we get over half of our oil from, decline at the slowest rate after peaking: 6% on average. So when all oil fields are declining, the minimum rate of decline is 6%, and giants and the other 49,000 other oil fields have exponential decline rates, so in 5 years, the average will be 7% and so on. That means in 16 years there’d be just 10% of the oil we had at peak. Social unrest and war are just as likely, if not more likely, than geological depletion to cause collapse within 20 years (which is the average of nearly all historic collapses according to Peter Turchin (a few posts about him are here: )
