Life After Fossil Fuels


In 2020, Jeff Gibbs’ documentary Planet of the Humans fell out of the sky.  It aimed a spotlight on the many ways in which solar and wind power were neither green nor renewable — no free pony.  In response, many “green” activists explosively soiled their britches and demanded that the film be banned.  Millions watched it.  Similarly, in 2021, Derrick Jensen and team published Bright Green Lies, which was soon followed by a documentary based on the book.  

These two projects were righteous fire-breathing exposés of the deceptions regularly made by folks promoting “green” technologies.  Passionate preaching can often get some folks to listen.  Sometimes it inspires minds to change.  Other folks prefer to have deeper understanding before revising their views.  Alice Friedemann’s book, Life After Fossil Fuels, will appeal to them. 

Without rage and condemnation, she calmly and carefully described why she thinks we would be wise to end our addiction to fossil fuels as soon as possible.  She evaluated the alternatives, and concluded that most are not free ponies.  Importantly, she carefully explained the benefits, limits, and faults of the various options, and meticulously cited the sources of her information — literally hundreds of them. 

Readers are introduced to the notion that alternative energy is not the magic key to a sustainable utopian wonderland.  The status quo is a high speed, ridiculously luxurious, one-way path into dark and treacherous realms.  We’ve been living like scruffy back alley gods on drugs.  The good news here is that no “green” solution can permanently keep the massively destructive status quo on life support — it’s going to end up where it’s headed.  “We are nearing the end of a one-time binge.”  Indeed!

So, my eyes began tap-dancing across page 1, and I was soon scrolling through a thrilling 86-page joyride.  Friedemann presented an informative and embarrassing birds-and-bees discussion of the horrific unintended consequences of our childlike obsession with living like crazy dysfunctional grownups.  I cheered with excitement with each new chapter.  It was so refreshing to experience such a sumptuous feast of clear and coherent bullshit free information. 

Readers are introduced to the important notion of EROI (energy returned on energy invested).  Each year it’s taking more and more energy to find, extract, process, and distribute fossil energy.  Imagine having a job that paid $100 per day, but the bridge toll for getting to work was $99.  For this reason, enormous amounts of fossil energy will remain in the ground forever, thank goodness!  About 65 percent of buried oil is technically or economically unrecoverable. 

The fracking industry is drilling like crazy, while more and more unlucky tycoons land with a splat in the tar pits of bankruptcy.  The richest discoveries were drilled and drained first.  “Globally, new oil discoveries have fallen for 6 years, with consumption of oil six times greater than discoveries from 2013 through 2019.”  Trouble ahead. 

In manufacturing, would it be possible to eliminate fossil energy by switching to wood-based fuel?  Take a wild guess.  Can we continue producing mountains of food when energy-guzzling synthetic fertilizers have become fond memories of the good old days?  Can industrial agriculture continue when energy-guzzling farm equipment runs out of affordable fossil energy to guzzle?  Will high speed horse carts haul fresh California veggies to Minnesota?

Can industrial civilization exist without energy-guzzling fleets of ships, planes, trains, and trucks?  “In the U.S., trucks deliver 80% of goods over 4.1 million miles of roads, with 80% of towns completely dependent on trucks.”  Can transportation systems shift to electric power?  “A truck with a driving range of 600 miles needs a battery pack weighing 35,275 pounds and can carry just 10,000 pounds.”  Oh, and cold weather reduces driving range by 35%.

“All contraptions that produce electricity need high heat in their construction.  They all need cement made at 2600°F.”  There is no known way to make concrete with electricity.  Making steel for wind turbines requires 3100°F (1700°C).  “Solar panels require 2700° to 3600°F (1500° to 2000°C) of heat to transform silicon dioxide into metallurgical grade silicon.”  Nuke plants still on the drawing board, in theory, might be able to generate 1562°F (850°C), but this is not hot enough for making cement, steel, glass, and lots of other stuff.

Friedemann’s key question is: could life as we know it continue in an alternative energy future?  By chapter 13, all contestants for powering a happy sustainable future were rejected, except one — biomass.  Prior to the fossil fuel era, heavy industry was powered by charcoal made from dead trees.  Brazil is still making steel with rainforest charcoal. 

“Biomass is the only renewable energy source that can generate the high heat needed by industry to make cement, iron, steel, aluminum, trucks, computers, electronic equipment, ceramics, bricks, and machinery.  Biodiesel is the only renewable drop-in fuel that can keep heavy-duty trucks, locomotives, and ships running.  Biomass, with a little help from hydropower, is the only renewable way to keep the electric grid up.”

Yikes!  This spooky paragraph sent a cold chill through my body.  Weird chapters followed.  I began to wonder if I had just wasted two entire days of the only life I may ever live.  But, by this point, I was aware that Friedemann had a whimsical side, so I kept reading, hoping for a sharp turn.  It came later.  Act two of the book was focused on contemplating how we could produce enough biomass to power industrial civilization, and prepare to feed the 3 billion additional folks expected for dinner in 2050.  Hope fiends will have a good cry.

Bummers obstructing the rise of a biomass utopia include climate change, freshwater scarcity, brutalized topsoil, and our addiction to countless fossil powered processes.  Turning biomass into a liquid fuel known as ethanol is idiotic.  Trucks can’t guzzle it, and it refuses to be pumped through pipelines.  It takes about as much energy to make a gallon as the finished gallon contains.  (Ethanol is a monster child fathered by gold plated government subsidies to Big Ag.) 

The bummer parade is long and unusual.  Make biodiesel with algae?  Make ethanol with seaweed, sorghum, or corn stalks?  Biodiesel could indeed replace oil-based diesel, if we were able to produce it in high volume.  This would require enormous amounts of cropland, and it would pummel the land as much as other types of agriculture.  If climate shifts blindside farm country, game over.

Bottom line: “The electric grid can not stay up without natural gas due to a lack of energy storage.  Transportation, agriculture, and manufacturing can not be electrified.  If transportation can not be electrified or run on Something Else, civilization as we know it ends.  Agriculture goes back to horses and human labor.”  When readers finally reach chapter 33 and slither across the finish line, their brains have been reduced to a bucketful of steaming glop.  It doesn’t look like we’re on the Yellow Brick Road to the Emerald City.  The sky is full of flying monkeys.  What a book!

The pisser here is that this very important book is sold by a textbook publisher, and it’s very expensive.  It won’t be able to catch much of a ride on the wave of interest generated by Gibbs, Jensen, and others.  Its modest collegiate audience is mostly the well-dressed offspring of the idle rich, and desperate students who are massively in debt.  Non-billionaires may need to rob a gas station, or get a library card.

The bigger pisser is that 12 year olds don't already know this stuff.  Maybe it would be polite to inform youngsters about the challenging future they have inherited.  I hope that Friedemann is busy working on something like a Dick and Jane primer for school kids — an affordable, competent, un-redacted, easy to read, mind-expanding introduction to actual reality, warts and all.  Imagine that.

Afterburn


Once upon a time, Richard Heinberg was a mild-mannered college professor in northern California.  In 1998, he happened to read an article in Scientific American that revealed the peak oil theory.  A small clan in the lunatic fringe had been discussing the notion, but it was now being yanked out of the closet by a number of retired petroleum geologists — respectable experts having front line experience with an increasingly ominous reality.

Peak oil was terrifying.  The geologists were telling us that our way of life was racing toward the cliff.  Dignified ladies and gentlemen naturally swept it under the carpet, because the notion was certainly impossible in this age of techno-miracles.  Anyway, the anticipated calamity was still 20 or 30 years away, so there was no need to think about it.

In 2003, Heinberg published The Party’s Over, which explained peak oil to a general audience.  Since then, he’s made a career out of exposing the dark side of growth, progress, and other mischief.  Eventually, he left the university and joined the Post Carbon Institute.  His message is that resource depletion, climate change, and economic meltdown will blindside our way of life in this century.  He suggests that now is a great time to pay closer attention to reality.

Decades of explosive economic growth were only possible because of cheap and abundant energy, abundant high quality mineral resources, and highly productive oil-powered agriculture.  Today, the perpetual growth monster is kept on life support by pumping it up with trillions of dollars of debt.  Back in the 1960s, a dollar of debt boosted the GDP by a dollar.  By 2000, a dollar of debt boosted GDP by just 20 cents.  Today, the tsunami of debt is creating a new stock market bubble, and its collapse may be worse than the crash of 2008.  The notion that “growth is over” inspires the titans of finance leap from tall buildings.

Well-paid goon squads of spin-doctors are effectively conjuring doubts about peak oil.  What they don’t mention is the energy returned on energy invested (EROEI).  A century ago, it took one calorie of energy to produce 100 calories of petroleum.  The EROEI was 100:1.  Today, the EROEI of U.S. production has plummeted to 10:1.  Tar sands, oil shale, and biofuels all are less than 5:1.  Most fossil energy will be left in the ground forever, because of low or negative EROEI.  Imagine having a job that paid $100 a day, but the bridge toll for getting there was $105.

It’s already too late to cleverly pull the plug on climate change and live happily ever after.  Our current strategy, ignoring the problem and denying it exists, is the preferred policy of our glorious leaders.  It might be possible to soften the worst-case scenario if we reduced our fossil fuel consumption by 80 to 90 percent by 2050, a daunting challenge.  The transition to renewable energy will be turbulent, because of its numerous shortcomings.  For example, trucks, planes, and agriculture cannot run on electricity.  Many uses of oil have no substitute.

Welcome to the subject matter of Heinberg’s latest book, Afterburn.  We’re living in the final decades of a one-time freak-out in human history, the Great Burning.  For two centuries, we’ve been extracting and burning staggering amounts of sequestered carbon, for no good reason.  What were we thinking?  It’s nonrenewable, so using it as the core energy source for industrial civilization could only have a crappy ending.  For thousands of years, Arab herders traveled across regions containing oceans of oil, left it alone, and enjoyed a good life.  Self-destruction is not mandatory.

The book takes readers on an up-to-date tour of the unintended consequences of the Great Burning, and presents reasonable arguments for why it’s moving into the sunset phase.  The final chapters of Afterburn contemplate life after the burn.  What can intelligent people do to prepare for a way of life that will be far smaller, simpler, and slower?

In the 1930s, a Nazi control freak named Joseph Goebbels revolutionized mind control via high-tech propaganda.  This was made possible by the latest consumer fad, radio.  One person spoke, and millions listened, day after day.  Today, with the internet, and hundreds of TV channels, many millions are speaking at once, presenting a fantastic variety of viewpoints.  Truth (if any) can become a needle in the haystack.

Many huge ideas have been born in the lunatic fringe, presented by heretics like Galileo and Darwin.  At the same time, the fringe produces oceans of idiotic balderdash.  At the opposite end of the spectrum is the mainstream world, where the one and only thing that matters is ongoing economic growth.  Other issues, like climate change and resource depletion, are nothing more than annoying distractions that must be stepped around.

Heinberg is interesting because he camps in the no-man’s-land between shameless mainstream disinformation and the wacko hysteria of the fringe.  He’s a likeable lad, and a clear writer who makes an effort to be respectful and fair-minded.  Until recently, it’s been compulsory for eco-writers to include hope and solutions, even if they’re daffy, because bummer books gather dust.  It’s encouraging to see an emerging trend, in which the emphasis on hopium is becoming unhip, and readers are served larger doses of uncomfortable facts with no sugar coating.

Afterburn includes small servings of magical thinking, but overall it lays the cards on the table.  A way of life can only be temporary if it is dependent on nonrenewable resources, or on consuming renewables at an unsustainable rate.  An economy requiring perpetual growth is insane.  Nature will fix our population excesses and eliminate overshoot.  The lights will go out.  All civilizations collapse.  Ours will too.  We won’t be rescued by miraculous paradigm shifts.  The biggest obstacle to intelligent change is human nature.  Folks with food, money, and a roof don’t worry about threats that are not immediate.  There is a possibility that humankind will no longer exist by the end of this century.  And so on.

Yes, things can look a little bleak, but don’t surrender to cynicism and give up.  We can’t chase away the storm, but we can do many things that make a difference.  Learn how to do practical stuff, like cook, sew, and garden.  Become less reliant on purchased goods and services.  Develop trusting relationships with your neighbors.

Today is a paradise for folks interested in changing the world.  Imagine cool visions of a new and improved future where we could nurture cooperation, eliminate inequality, mindfully manage population, and minimize environmental injuries.  Unfortunately, visioning is limited by the fact that the future is certain to be radically different.  What can we say for sure about 2050?  I remain stubbornly confident that there will be sun and moon, mountains and oceans, bacteria and insects.

When civilizations die, most or all of their cultural information also dies.  Today, much of this information is stored in electronic media, or printed on acidic paper that has a short lifespan.  Heinberg believes that it’s essential to protect our books, because they are vital for cultural survival.  He fears that the amazing achievements of the Great Burning will be forgotten.  “Will it all have been for nothing?”

A far better question is, “What cultural achievements would we want to be remembered by?”  During the Great Burning, we’ve learned so much about environmental history and human ecology.  We are coming to understand why almost every aspect of our way of life is unsustainable.  (Our schools should teach this!)  The most valuable gift we could give to new generations is a thorough understanding of the many things we’ve learned from our mistakes, and the mistakes of our ancestors.  They need a good map of the minefield.
