Nonrenewable Geology

 These days, we are constantly assured that our leaders and experts will do what’s necessary to promptly eliminate climate change, and open the gate to a clean green renewable utopia.  A golden bonus is that spending staggering amounts of money to radically alter the energy-related infrastructure of the entire world will be great for the economy, thrill investors, and create jobs, jobs, jobs!  If we have a fervent blind faith in this miracle, we can relax, keep our lives on autopilot, and shop till we drop.

According to bright green dreams, the answer to all our prayers is to simply abandon fossil energy right away, and power the global economy with wholesome carbon-free renewable electricity.  Not everyone agrees.  The mainstream media, and many environmental activists, have yet to acknowledge the grumpy skeptics who assert that it’s impossible for today’s industrial civilization, as we know it, to be entirely powered by any flavor of electricity, whether renewable or conventional.

Megan Seibert and William E. Rees explained why.  Their report relied heavily on research by Alice Friedemann.  Only fossil fuel can generate the intense heat needed to mass produce stuff like steel, concrete, silicon, and so on.  It’s also essential for keeping the current transport system on life support (trucks, trains, ships, planes, cars, etc.) — both manufacturing the machines, and fueling their lifetime operation.  A team led by Derrick Jensen focused additional attention on bright green hopium.

And now, at long last (sorry!), I shall get to the point of my message.  I recently learned about a thousand page report created by the Geological Survey of Finland, a government agency that employs 400 experts.  Geologists don’t believe in miracles, they believe in minerals — finite nonrenewable substances, resources that are diminished with each scoop of the power shovels.  Every passing year, the reserves get smaller, lower in quality, and more expensive to extract.

The Finnish geologists wondered if seemingly unbelievable miracles were actually possible in reality.  They contemplated what modifications would be needed to 2019 technology, in order to create a perfectly sustainable utopia by 2050.  The theoretical transition required super-massive global changes to be made in an unimaginably super-speedy manner.

The heroic geologists stumbled upon an important discovery.  One minor detail had somehow been overlooked by the clean green renewable dreamers.  Their primary focus had been on carbon, climate, positive thinking, and saving the world.  It seems there was little or no awareness that the miraculous global transition required huge amounts of specific minerals.  Some of the essential minerals were needed in quantities that far exceeded the world’s known resources and reserves.  The titanic dream smacked into an iceberg.  The geologist’s report focused on three subject areas: transport, electricity generation, and industrial manufacturing. 

[A quick vocabulary lesson.  “Reserves” are the amount of a resource that can profitably be extracted with existing technology at current prices.  “Resources” are the currently known amount of a resource, only a portion of which can be considered reserves.]

The Finnish report explained that the planet-thrashing monster we have created took more than a century to become uncontrollably catastrophic.  It was only made possible by guzzling staggering amounts of cheap and abundant oil, an extremely energy dense fuel.  Our monster has devoured massive amounts of high quality mineral resources.  At the peak of the joyride, folks in wealthy nations enjoyed a fantastic orgy of utterly idiotic waste.

And now, the monster must be ethically euthanized as soon as possible.  Energy is no longer cheap.  Mineral resources are lower in quality, and far less abundant.  Financial systems are loaded with debts, and full of surprises.  The planet’s ecosystems are disintegrating in front of our eyes, as the population explosion continues soaring.  World leaders are busy butting heads, shooting missiles, and cutting throats.  Alas, the Finnish geologists are not giddy with optimism for a quick and easy bright green future.

In the global energy system of 2018, fossil fuels provided 84.7% of the power, nuclear was 10.1%, and renewables were just 4.05% (solar, wind, geothermal, hydro, biofuels, etc.).  In other words, nonrenewable energy (fossil + nuke) provided about 95% of the monster’s life force.  The geologists focused on energy processes that involved minerals.  So, they didn’t mention humankind’s original energy resource, muscle power — it’s not a wildly exciting alternative, but it has a promising future.  Imagine everyone wearing bright green MAWA hats (Make America Walk Again).

Obviously, transport systems should rapidly eliminate carbon belching Internal Combustion Engine (ICE) technology.  Most green dreamers envision a shift to Electric Vehicle (EV) technology that utilizes rechargeable batteries or fuel cells.

EVs are a very trendy idea today.  Battery powered EVs are charged with electricity from the grid.  But if the grid is delivering electricity that’s maybe 95% nonrenewable, that’s what their batteries will be charged with.  How green is that?  Of course, an EV’s frame, fenders, battery, motor, etc., are not made of harmless green fairy dust.  Neither are solar panels, wind turbines, or roadways made of asphalt or concrete.  Walking has far less impact.

Fuel cell powered EVs use a chemical reaction to generate electricity from hydrogen.  During operation, they emit only water.  Hydrogen in pure form does not exist in the natural world.  Energy is required to separate hydrogen from other compounds.  The U.S. Department of Energy says that about 95% of hydrogen is made by processing natural gas (CH4).  The Finnish report mentioned an uncomfortable fact: “A potential downside is that much less electricity is harvested from hydrogen in a fuel cell than the electricity required to produce that same volume of hydrogen.”

In 2019, the global transport fleet included about 1.416 billion cars, trucks, buses, and motorcycles, of which 1.39 billion were ICE.  These ICE machines need to be sent to the crusher as soon as possible.  Is it possible (or ecologically intelligent) to replace them with EVs?

Batteries are a serious challenge for both transport and electricity generation.  I’ll chat more about batteries shortly.  First, let’s take a peek at electricity generation.  It produces energy that is the life force of the grid, the stuff that lights the night, powers appliances, and entrances glowing screen zombies.  As mentioned, electricity generation is currently fueled by energy that is maybe 95% nonrenewable, a huge drawback.

Currently, the grid is designed to reliably distribute electricity from large centralized power plants, something like a hub and spokes.  A renewable energy grid would have to distribute electricity produced by numerous, smaller, widely dispersed facilities (wind and/or solar).  These produce power intermittently, taking naps when the winds go calm, or the sunbeams stop — sometimes for extended periods.

Meanwhile, the end-user demand for electricity constantly rises and falls throughout the day.  Today’s power generation infrastructure is carefully designed to react to the frequent ups and downs of demand, by quickly delivering less or more electricity into the grid.  If this was not the case, life would have many more technological headaches.

On the other hand, a wind turbine farm pays no attention whatsoever to end-user demand.  More wind, more power.  No wind, no power.  The same is true for solar panel arrays, and the variable inflow of sunbeams.  For these systems to work, large scale battery infrastructure is needed to effectively store surplus energy when generation exceeds demand, and then later release stored energy whenever demand exceeds generation.  In northern regions, demand zooms higher when winter moves in, so the battery backup buffer would ideally need to store maybe four weeks of electricity — a huge challenge.  Nobody knows if this is even possible under real world conditions.

There are two forms of electricity, AC and DC.  The grid can only carry AC power.  When you plug a gizmo into a wall receptacle, it receives AC.  AC cannot be stored — once it is fed into the grid, it will either be used or lost.  Surplus AC can be converted to DC, which can be stored in a backup buffer battery, for later use.  When demand rises, DC in the battery can be converted to AC, and fed back into the grid.  Your cell phone and flashlight have batteries, because they run on DC.  Solar panels and wind turbines produce DC, which can be stored in batteries. 

And now, the plot thickens.  Lithium-ion batteries provide the most efficient storage.  To power 1.39 billion EVs, an estimated 282.6 million tons of batteries would be needed.  Plus, vastly more battery infrastructure would be needed to provide the storage buffer for the grid — an additional 2.5 billion tons!  So, to enable both EVs and grid buffer storage, an estimated 2.78 billion tons of batteries would be needed.  “This far exceeds global reserves of nickel, cobalt, lithium, and graphite.”  Without adequate storage buffers, “the wind and solar power generation may not be able to be scaled up to the proposed global scope.”

Indeed, the geologists wondered if there are adequate mineral resources to make batteries for just the 1.39 billion EVs.  They wrote, “Preliminary calculations show that global reserves, let alone global production, may not be enough to resource the quantity of batteries required.”  Oh, and those 1.39 billion EV batteries would have a useful working life of just of 8 to 10 years.  And the wind turbines and solar panels also have limited lifespans, 20 to 30 years or so.  Everything will need periodic replacement, from now to eternity.  For this reason, Alice Friedemann suggests that “renewable” should more accurately be referred to as “rebuildable.”  No free lunch.

Mineral resources are neither infinite, easily available, nor cheap.  The massive transition to renewables looks more like a frantic short term plastic bandage, rather than an effective, well planned permanent cure.  The geologists conclude that a transition to renewable energy seems to be seriously hobbled by the limited availability of nonrenewable minerals. 

The recipe for lithium-ion batteries requires five essential minerals: copper, nickel, cobalt, lithium, and graphite.  Are there adequate reserves of these minerals to manufacture all those batteries?  No, not even close.  EV transport would need 1.39 billion batteries.  “In theory, there are enough global reserves of copper if they were exclusively used just to produce lithium-ion batteries for just one generation of vehicles.”  Reserves of the other four minerals are not adequate to make all of those EV batteries.  See the chart on page six of the report’s summary. [LINK]

So, we’ve looked at transport and electricity generation, and their theoretical renewable options.  The third focus of the Finnish report was industrial manufacturing.  What are the theoretical options for running industrial systems on renewable energy?  The geologists can’t think of any.  See the chart on page two of the report’s summary.

Simon Michaux authored the Finnish report.  He wrote, “In conclusion, this report suggests that replacing the existing fossil fuel powered system (oil, gas, and coal), using renewable technologies, such as solar panels or wind turbines, will not be possible for the entire global human population.  There is simply just not enough time, nor resources to do this by the current target set by the world’s most influential nations.  What may be required, therefore, is a significant reduction of societal demand for all resources, of all kinds.  This implies a very different social contract and a radically different system of governance to what is in place today.  Inevitably, this leads to the conclusion that the existing renewable energy sectors and the EV technology systems are merely steppingstones to something else, rather than the final solution.  It is recommended that some thought be given to this and what that something else might be.”

GeoDestinies 2022


 

Walter Youngquist (1921-2018) was a petroleum geologist, a University of Oregon professor, and my friend.  His life’s masterpiece is a 600 page book that’s now available to everyone as a free PDF download [HERE].  

Geologists study Earth resources, many of which are being degraded and depleted — aquifers, topsoil, hydrocarbons, minerals, etc.  These resources have limits.  Every drinker learns that the glass starts full, ends empty, and the faster you drink it, the quicker it’s gone.  Consumers pay little attention to resource limits, but they’re beginning to comprehend the impact of carbon emissions on the climate.  Mainstream experts repeatedly tell us not to worry.  They preach a fervent blind faith in miracles — a smooth and easy transition to a clean, green, renewable utopia.  Geologists wince. 

Youngquist didn’t believe in miracles or techno utopias.  Today, we’re living dangerously fast by destroying astonishing amounts of nonrenewable resources — a onetime binge that can never again be repeated.  Nonrenewable energy is finite.  We have been soaring in a beautiful dream world, where the air is perfumed with the intoxicating aroma of a nonrenewable prosperity.  The era of cheap energy is fading away in the rear view mirror. 

In 1973, the Eugene newspaper wrote a story about one of his lectures, “Dark Picture Painted by Youngquist.”  He gave many talks to Chamber of Commerce groups, trying to introduce them to the concept of limits.  He was almost never invited back.  America worships perpetual growth at any cost.  Growth is our god word.

In the mid-1990s, a number of the world’s petroleum geologists became alarmed that the volume of new oil discovered was declining, while the volume of consumption continued soaring.  This inspired the dawn of the Peak Oil movement, a wakeup call.  In 1997, Youngquist published GeoDestinies, which quickly sold out.  Folks begged him to print more, but Walt was reluctant.  He wanted to update the info first, but the story was moving faster than he could type. 

Finally, in 2012, he finished the update.  Unfortunately, the process hit some curves.  The book did not get to a printer, Walt died, the publisher went extinct, and the manuscript gathered dust.  In 2022, a small group of fans was able to get a digital copy, and make it available to the world.  Most of the content is still timely and very important.  For most readers, this book is largely going to be a banquet of new information, important stuff that’s rarely taught in school, if ever.

Today, many snicker at the Peak Oil dimwits.  Dudes, we didn’t run out!  We’ll always find more!  In the ’90s, the industry was primarily producing cheap and easy conventional oil (insert a straw and suck).  It appears that the global production of this oil peaked around 2005.  Unfortunately, mad scientists developed new technology for extracting oil, like hydro-fracking and horizontal drilling.  This enabled a sharp increase in the production of unconventional oil from sources including tar sands, heavy oil, shale oil (tight oil), and deep water wells.  This oil was far more challenging and expensive to extract (and the mother of many bankruptcies).

In addition to declining discoveries, a new boogeyman is EROEI (energy returned on energy invested).  It takes energy to extract fossil energy.  For example, a hundred years ago, the EROEI for conventional oil was very high.  Ram a drill into a huge pool of Texas oil, and a geyser of black gold often shot high in the sky.  Today, with the shift toward unconventional oil, the EROEI is far lower and declining.  As the energy needed for extraction approaches the energy content of the output, the industry moves closer to its expiration date.  A lot of fossil energy will be left in the ground forever. 

It took more than 500 million years for geologic forces to transform plant and animal residue into fossil fuels — coal, oil, and natural gas.  It will take less than 500 years for humans to extract it and burn it.  We live during a brief blip in Earth history, an ecological hurricane.  Walt’s core message was a blunt warning.  “The momentum of population growth and resource consumption is so great that a collision course with disaster is inevitable.  Large problems lie not very far ahead.  …In some respects, the twenty-first century will be like the twentieth century in reverse.”

The public believes that adequate “renewable” substitutes will be available when needed.  Alternative energy is not clean, green, and free.  The hardware components have limited working lifespans.  Scaling up to replace nonrenewable energy would require vast land area, roads, power lines, and backup for when adequate wind or sunbeams are unavailable.  Manufacturing solar panels requires critical minerals like cobalt, gallium, germanium, indium, manganese, tellu­rium, titanium, and zinc.  Each wind turbine requires tons of concrete, steel, and other resources.

Walt described the alternative energy options, and their many limitations.  He concluded that renewable energy will not come close to replacing fossil energy.  In 2021, Alice Friedemann presented a far more thorough discussion in her book Life After Fossil Fuels.  A renewable utopia seems impossible. 

Oil is just one of many Earth resource topics in Walt’s book.  Plants and animals don’t need it.  Less than 200 years ago, oil was of no great importance to anyone anywhere.  For many thousands of years, nomads wandered across the Arabian Peninsula, under which laid oceans of ancient oil.  It never occurred to them to extract it, burn it, blindside the climate, and race down crowded highways in powerful motorized wheelchairs.  Naturally, in those days, the planet was in far healthier condition.  Then, in the twentieth century, Arabia became very rich, very fast.

Other resources are genuinely essential for the survival of the family of life — soil, water, air, and sunlight.  Of all minerals, soil is the most precious by far.  Fertile soil is created so slowly that, from a human perspective, it’s essentially nonrenewable.  In his book Dirt, geologist David Montgomery wrote, “Continued for generations, till-based agriculture will strip soil right off the land as it did in ancient Europe and the Middle East.  With current agricultural technology though, we can do it a lot faster.”  Peter Salonius studied soil for 44 years.  He concluded that all extractive agriculture, from ancient times to the present, was unsustainable. 

The problems associated with soil destruction are widely understood, and widely disregarded.  Nobody became a billionaire by promoting soil conservation.  Globally, billions of tons are lost every year.  Overall, one-third of the soil on U.S. cropland has been lost over the past 200 years.  Half of the excellent topsoil of Iowa is already gone.  The highest quality soil is close to the surface, and the first to erode.  Walt wrote, “Worldwide, the con­tinuing loss of soil and depletion of groundwater is leading humanity directly over the cliff.”   

All life needs water.  Water allows mineral nutrients in the soil to be absorbed by plants.  Your body is about 60 percent water.  In some regions, farms receive adequate water from precipitation.  Other regions require irrigation.  About 17 percent of cropland is irrigated, but it produces 40 percent of the world’s crops. 

Some underground aquifers are unable to recharge as fast as pumps are extracting the water — like the vast Ogallala aquifer in the U.S. midlands.  They are unsustainable water mines.  Several communities in Colorado are (temporarily) drinking from reservoirs of 10,000 year old water.  Forty percent of humankind now lives in regions with chronic water shortages, especially Africans, with their rapidly growing populations. 

When ancient aquifers are depleted, subsidence can occur — the ground sinks, filling the empty space where the water once was.  This makes it impossible for the aquifer to ever refill again.  In some portions of Mexico City, subsidence has lowered the ground surface up to 28 feet (8.5 m), causing much damage.  Irrigation can also lead to the accumulation of salt in the soil, which eventually creates a permanent wasteland.  In the cradle of civilization, the once thriving Tigris Euphrates floodplain is now “a glistening desert of salt.”

Earth resources have played a starring role in world history.  They enable the rise of civilizations, and their limited eras of prosperity.  It’s no coincidence that the Industrial Revolution began in Britain, because they had abundant deposits of coal, iron, and limestone in convenient locations.  The U.S. skyrocketed into a global superpower by exploiting huge deposits of a wide variety of Earth resources.  In World War II, Japan was short on iron, coal, and oil.  Hitler invaded southern Russia in an effort to seize the huge Baku oilfields.

In coming years, as fossil fuel fades out, agriculture will once again be muscle powered and low tech (if the climate crisis allows crop production to continue).  Industrial scale food processing and distribution will fizzle.  Potent synthetic fertilizers and other agrichemicals will no longer be available.  As harvests decline, population growth will shift into reverse. 

Finally, a few footnotes.  GeoDestinies was written on a tiny digital typewriter that allowed files to be saved on a floppy disk.  As Walt typed, the display presented a single line of text.  He never owned a computer, and never had direct access to the internet or email.  He had no spare time.  Finishing this manuscript was job one.

I gave him prints of interesting online stuff, and copies of my book reviews, including Brian Fagan’s The Great Warming, and The Little Ice Age.  The Fagan reviews reinforced his belief that climate always changed.  Back in 2012, the notion that human-caused emissions were disrupting the climate was still controversial in the mainstream mindset.

In his 96 years, Walt witnessed remarkable changes in the American standard of living.  These were only possible because of our maniacal binge of energy guzzling.  Modernity’s high standard of living, and fabulous healthcare was awesome.  But the long term environmental impact of these short term benefits was huge.

He lacked some sympathy for environmentalists who opposed energy development projects in America, whilst they were enjoying a comfortable consumer lifestyle.  High impact projects were often diverted to poor nations that had few regulations, if any.  In 2012, Walt was not fully aware of the serious long term hazards of nuclear energy, and the lack of permanent storage for high level radioactive wastes.

Walt was especially horrified by exponential population growth.  In his lifetime, the human mob skyrocketed from 1.9 billion to 7.6 billion.  He was deeply disappointed that overpopulation was a taboo subject for secular and spiritual leaders.  Large numbers of immigrants to the U.S. came from cultures where large families are the norm.  Their dream was to live a maximum impact consumer lifestyle.

Youngquist’s book pulls away cultural blindfolds, and provides a mind-expanding full immersion baptism in the actual facts of life.  “The confluence of factors soon at hand may make this century the most turbulent in human history.  There will be adjustment of population size.  There will be a new energy paradigm.  There will be lifestyle change.  There will be great economic change.  There will be environmental change.  Although change has always been the order of life, the particular confluence of major factors in each of these areas will make the twenty-first century a fundamental turning point for mankind.”

Walt completed the manuscript of the second edition in 2012.  Since then, he wrote four papers for the Negative Population Growth Forum.  Our Plundered Planet (2014), A Geomoment of Affluence (2015), The Scale of Things (2016), Framework of the Future (2016).
