Vaclav Smil On The Two Cultures And Our “Fully Post-Factual World”

Vaclav Smil On The Two Cultures And Our “Fully Post-Factual World”

My emails with Smil on C.P. Snow’s 1959 essay, scientific illiteracy and innumeracy. Plus: Kotkin, Gurri, and Teixeira on the elites vs. the “normies”

In 1959, British novelist and physical chemist C.P. Snow gave a now-famous lecture called “The Two Cultures.” Snow argued that there was a growing disconnect between the culture of the sciences and the culture of the humanities and that bridging that gap was critical to understanding and addressing the world’s problems. Snow declared,

I believe the intellectual life of the whole of western society is increasingly being split into two polar groups… Literary intellectuals at one pole – at the other scientists, and as the most representative, the physical scientists. Between the two a gulf of mutual incomprehension.

Snow then underscored the general public’s lack of understanding of energy. As Snow put it:

A good many times I have been present at gatherings of people who, by the standards of the traditional culture, are thought highly educated and who have with considerable gusto been expressing their incredulity at the illiteracy of scientists. Once or twice I have been provoked and have asked the company how many of them could describe the Second Law of Thermodynamics. The response was cold: it was also negative. Yet I was asking something which is the scientific equivalent of: Have you read a work of Shakespeare’s?

Indeed, while most moderately cultured people will be familiar with the Bard’s A Comedy of Errors or The Merchant of Venice, the three laws of thermodynamics are considered by most people to be the domain of nerds and wonks…

Vaclav Smil: We Must Leave Growth Behind

On September 23, the United Nations opened its Climate Action Summit here in New York, three days after the Global Climate Strike, led by Greta Thunberg, swept through thousands of cities worldwide. To mark the occasion, Intelligencer will be publishing “State of the World,” a series of in-depth interviews with climate leaders from Bill Gates to Naomi Klein and Rhiana Gunn-Wright to William Nordhaus interrogating just how they see the precarious climate future of the planet — and just how hopeful they think we should all be about avoiding catastrophic warming. (Unfortunately, very few are hopeful.)

Vaclav Smil cuts an unusual figure in the climate world — an iconoclastic Czech-Canadian scientist, he is often called the person who understands energy transitions better than anyone else in the world. (Bill Gates is a particular fan.) But his view of energy transitions is, famously, dour — that it will take, at least, many more decades to produce a transition to renewable energy than most analysts and advocates predict and that a total transition may prove tremendously difficult.

In his new book, Growth — a dense, 500-page treatise that covers everything from “microorganisms to megacities,” whose afterword we’re excerpting here — Smil makes perhaps an even-more-off-putting proposition: that in order to “ensure the habitability of the biosphere,” we must at the very least move away from prioritizing growth and perhaps abandon it entirely.

Let me start by asking you about the very end of the book. I know so much of this was written in a spirit of caution and care and wanting to avoid drawing long-term, large-scale conclusions from the material. But from my read, at least, it ends on a quite definitive note…

Vaclav Smil: ‘Growth must end. Our economist friends don’t seem to realise that’

Vaclav Smil

The scientist and author on his latest book – an epic, multidisciplinary analysis of growth – and why humanity’s endless expansion must stop.

Vaclav Smil is a distinguished professor emeritus in the faculty of environment at the University of Manitoba in Winnipeg, Canada. Over more than 40 years, his books on the environment, population, food and energy have steadily grown in influence. He is now seen as one of the world’s foremost thinkers on development history and a master of statistical analysis. Bill Gates says he waits for new Smil books the way some people wait for the next Star Wars movie. The latest is Growth: From Microorganisms to Megacities.

You are the nerd’s nerd. There is perhaps no other academic who paints pictures with numbers like you. You dug up the astonishing statistic that China has poured more cement every three years since 2003 than the US managed in the entire 20th century. You calculated that in 2000, the dry mass of all the humans in the world was 125m metric tonnes compared with just 10m tonnes for all wild vertebrates. And now you explore patterns of growth, from the healthy development of forests and brains to the unhealthy increase in obesity and carbon dioxide in the atmosphere. Before we get into those deeper issues, can I ask if you see yourself as a nerd?
Not at all. I’m just an old-fashioned scientist describing the world and the lay of the land as it is. That’s all there is to it. It’s not good enough just to say life is better or the trains are faster. You have to bring in the numbers. This book is an exercise in buttressing what I have to say with numbers so people see these are the facts and they are difficult to dispute.

GROWTH: From Microorganisms to Megacities

GROWTH: From Microorganisms to Megacities

Vaclav Smil’s latest book explores growth in nature and society. It examines the rules and patterns of growth in four key domains, those of the living world; human energy consumption; human artifacts; and human populations, societies and economies. The author is a passionate advocate of quantitative analysis, and thus Growth is filled with numbers, graphs and mathematical notation. Yet it’s written to be easily understood by non-mathematicians, making brilliant but accessible use of statistics to illustrate salient features of growth in all its terrestrial forms (the book’s scope is limited to Earth). In short, Growth is a compelling read for statisticians and non-statisticians alike.

A favorite author of Microsoft cofounder Bill Gates and a Foreign Policy magazine Top 100 Global Thinker, Smil is known for his multidisciplinary approach, energy-related expertise and penchant for packing his many books with all manner of fascinating facts. Growth‘s chapter on the biological realm supplies as fine a sampling of this latter propensity as can be found. Did you know that average dinosaur body volumes declined at the beginning of the final period of the Mesozoic era but then made a near-comeback to their previous highs by the time of the dinosaurs’ extinction? You will after reading this book–and if you’re as much of a nerd as I am, you’ll relish this and innumerable other scientific tidbits. You’ll also be awed by the 100-page bibliography and the fact that scarcely a sentence goes by without some bit of quantitative analysis or scholarly citation.

A Novel

Prehistoric trivia aside, Smil’s chapter on the living world rightly focuses on those life forms most necessary to humanity’s survival and the functioning of the biosphere. These include, of course, modern-day trees and forests, microorganisms, agricultural crops and animals.

Replacing diesel tractors with horses or oxen – what will that be like?

Replacing diesel tractors with horses or oxen – what will that be like?

Preface.  Since fossil fuels are clearly finite, at some point increasing numbers of farmers with diesel vehicles and equipment will want to replace them with horses, which can do the work of six people.  Here’s what  energy expert Vaclav Smil has to say about that.

***

Vaclav Smil. 2017. Energy and Civilization A History. MIT Press.

During the 1890s a dozen powerful American horses needed some 18 tonnes of oats and corn per year, about 80 times the total of food grain eaten by their master.

Only a few land-rich countries could provide so much feed. Feeding 12 horses would have required about 15 ha of farmland. An average U.S. farm had almost 60 ha of land in 1900, but only one-third of it was cropland. Clearly, even in the United States, only large grain growers could afford to keep a dozen or more working animals; the 1900 average was only three horses per farm.

Even in land-rich agricultures with extraordinary feed production capacities the substitution trend could not have continued much beyond the American achievements of the late 19th century. Heavy gang plows and combines took animal-drawn cultivation to its practical limit. Besides the burden of feeding large numbers of animals used for relatively short periods of field work, much labor had to go into stabling, cleaning, and shoeing the animals. Harnessing and guiding large horse teams were also logistical challenges. There was a clear need for a much more powerful prime mover—and it was soon introduced in the form of internal combustion engines.

The simplest way of transporting loads is to carry them. Where roads were absent people could often do better than animals: their weaker performance was often more than compensated for by flexibility in loading, unloading, moving on narrow paths, and scrambling uphill.

Vaclav Smil. Making the modern world: materials and dematerialization

Vaclav Smil. Making the modern world: materials and dematerialization

Preface.  I can’t believe I read this book, it is just a long litany of the  gigantic amounts of materials we exploit, with no analysis, implications, or the meaning of what impact this will have on the planet.

I certainly don’t expect anyone to read even this shortened version of his book, but it might be worthwhile to skim for an idea of how much material we’re consuming.

As I point out in my review of the United Nations 2016 report Global material flows and resources productivity” here, in order to accommodate an additional 2 billion people in 2050, material consumption will need to nearly triple to 180 billion tonnes of materials, almost three times today’s amount. If 180 billion tonnes grows in the future at a 5% compound rate, in 497 years the entire earth will be consumed, all 5.972 x 1021 tonnes of it, and we’ll be floating in outer space.

After reading this book, it’s hard to believe there’s anything left to exploit, though here it is 5 years later and the earth is still being pillaged.  But from Smil’s gargantuan numbers and the exponential exploitation of just about everything, clearly this will end badly.  The issue of peak sand has been in the news more frequently lately, which is essential for civilization to make concrete, computer chips, solar PV, and fracking.

Smil covers a wide range of materials that are essential to civilization that you may not have thought much about, and all the myriad uses of silicon, plastics, nitrogen, aluminum, steel, hydrogen, ammonia, cement, and more.  All of them made possible by oil.  All of them essential for civilization, so if one fails….(Liebig’s law of the minimum).

Energy prospects: little to Smil about?

Energy prospects: little to Smil about?

Last week saw much of Britain in the grip of uncharacteristic snowstorms and freezing temperatures. The picture shows the woods near my holding in their snowy raiment. I thought it would be crowded when I went walking there, because it’s usually a popular spot. But with the roads impassable, it was almost deserted. Ah yes, traffic chaos – the cue for the usual British complaints about how bad we are at coping with a bit of snow (I always think a bad feature of British culture is our readiness to complain about how bad we are at things). No doubt it’s possible to blame the government (another common British pastime, though one I suspect not limited to this country alone) but the truth is we hardly ever have snow like this, and it would be pointless to stand constantly prepared for it. When I’ve been in places where heavy snows are a regular occurrence, what’s struck me most is the enormous fossil energy input invested in the snowploughs, gritting trucks, snow blowers, 4WDs, heating systems and so forth. All that ancient sunlight invested in keeping modern people moving, no matter what. In the 19th century Russia of Turgenev’s Sketches From A Hunter’s Album that I’m currently reading, what’s striking is that when travellers get hit by inclement weather they basically stay put, sometimes for weeks on end. Though to be fair, travelling in 19th century Russia was mostly a pursuit of the wealthy few. There’s nothing like serfdom for keeping you close to home.

Anyway, this is all vaguely relevant to my present theme, which is some thoughts on Vaclav Smil’s Energy and Civilization: A History (MIT Press, 2017). It’s hard to keep up with Smil’s output, since he seems to produce about three books every year, but I find him an interesting writer.

Revolution? More like a crawl

Revolution? More like a crawl

The energy visionary Vaclav Smil — Bill Gates’s favorite author — says that when our leaders promise quick energy transformations, they’re getting it very wrong.

America in 2015 finds itself almost in a new energy reality. It recently became the world’s secondlargest extractor of crude oil, and since 2010 has been the leading producer of natural gas, whose abundant and inexpensive supply has been accelerating the retreat from coal as a national source of electric power. 

Some see this as the beginning of an even bigger transition, one in which America’s dominant status as a producer of hydrocarbons ends its allies’ dependence on Russian gas and makes OPEC terminally irrelevant, while its entrepreneurial drive helps it quickly advance to harness renewables and reduce greenhouse gas emissions.

All of this sounds too good to be true — and it is. Indefensible claims of imminent transformative breakthroughs are an unfortunately chronic ingredient of American energy debates.

When American leaders talk about energy transitions, they tend to sell them as something that can be accomplished in a matter of years. Al Gore, perhaps the country’s most prominent climate activist,proposed to “re-power” America, making its electricity carbon-free, within 10 years, calling the goal “achievable, affordable and transformative.” That was in 2008, when fossil fuels produced 71 percent of American electricity; last year 67 percent still came from burning fossil fuels.

President Barack Obama, who has a strong rhetorical dislike of oil — although kerosene distilled from it fuels the 747 that carries him to play golf in Hawaii — promised in his 2011 State of the Union message that the country would have 1 million electric cars by 2015. That goal was abandoned by the Department of Energy just two years later.

The energy revolution will not be televised

The energy revolution will not be televised

Three recent news items remind us that energy transitions take time, a lot of time–far too much time to be shrunk down into a television special, a few talking points, or the next big energy idea.

For example, the complex management task of putting together the international fusion research project called the International Thermonuclear Experimental Reactor (ITER) has resulted in estimated final costs that have tripled since the 2006 launch. Fusion could theoretically offer clean and abundant energy almost indefinitely because it uses ubiquitous hydrogen* as fuel and creates helium in the process. (Water you’ll recall is two hydrogen atoms and one oxygen atom and is therefore the most abundant source of hydrogen.)

Despite nine years of effort, ITER has yet to carry out a single experiment; and, the project is not expected to do so for another four years. The idea for such an international project was hatched in 1985 during a summit between U.S. President Ronald Reagan and Mikhail Gorbachev, the leader of what was then still called the Soviet Union. Thirty years later fusion is still receding into the horizon of our energy future.

While there are certainly issues that are managerial rather than merely technical, the technical challenges remain enormous. After decades of experimentation, no laboratory has ever produced more energy from a fusion reaction than it took to create it. One of the most promising tests was performed last year at the National Ignition Facility of the Lawrence Livermore National Laboratory in California. This test produced about 17 kilojoules which was more energy than was used to create the fuel. Problem is, the lasers that initiated the fusion consumed about 2 megajoules or 118 times the amount of energy created by the test.
