INSTANT NEW YORK TIMES BESTSELLER “A new masterpiece from one of my favorite authors… [How The World Really Works] is a compelling and highly readable book that leaves readers with the fundamental grounding needed to help solve the world’s toughest challenges.”—Bill Gates “Provocative but perceptive . . . You can agree or disagree with Smil—accept or doubt his ‘just the facts’ posture—but you probably shouldn’t ignore him.”—The Washington Post An essential analysis of the modern science and technology that makes our twenty-first century lives possible—a scientist''s investigation into what science really does, and does not, accomplish. We have never had so much information at our fingertips and yet most of us don’t know how the world really works. This book explains seven of the most fundamental realities governing our survival and prosperity. From energy and food production, through our material world and its globalization, to risks, our environment and its future, How the World Really Works offers a much-needed reality check—because before we can tackle problems effectively, we must understand the facts. In this ambitious and thought-provoking book we see, for example, that globalization isn’t inevitable—the foolishness of allowing 70 per cent of the world’s rubber gloves to be made in just one factory became glaringly obvious in 2020—and that our societies have been steadily increasing their dependence on fossil fuels, such that any promises of decarbonization by 2050 are a fairy tale. For example, each greenhouse-grown supermarket-bought tomato has the equivalent of five tablespoons of diesel embedded in its production, and we have no way of producing steel, cement or plastics at required scales without huge carbon emissions. Ultimately, Smil answers the most profound question of our age: are we irrevocably doomed or is a brighter utopia ahead? Compelling, data-rich and revisionist, this wonderfully broad, interdisciplinary guide finds faults with both extremes. Looking at the world through this quantitative lens reveals hidden truths that change the way we see our past, present and uncertain future.

A comprehensive account of how energy has shaped society throughout history, from pre-agricultural foraging societies through today''s fossil fuel–driven civilization. "I wait for new Smil books the way some people wait for the next ''Star Wars'' movie. In his latest book, Energy and Civilization: A History, he goes deep and broad to explain how innovations in humans'' ability to turn energy into heat, light, and motion have been a driving force behind our cultural and economic progress over the past 10,000 years. —Bill Gates, Gates Notes, Best Books of the Year Energy is the only universal currency; it is necessary for getting anything done. The conversion of energy on Earth ranges from terra-forming forces of plate tectonics to cumulative erosive effects of raindrops. Life on Earth depends on the photosynthetic conversion of solar energy into plant biomass. Humans have come to rely on many more energy flows—ranging from fossil fuels to photovoltaic generation of electricity—for their civilized existence. In this monumental history, Vaclav Smil provides a comprehensive account of how energy has shaped society, from pre-agricultural foraging societies through today''s fossil fuel–driven civilization. Humans are the only species that can systematically harness energies outside their bodies, using the power of their intellect and an enormous variety of artifacts—from the simplest tools to internal combustion engines and nuclear reactors. The epochal transition to fossil fuels affected everything: agriculture, industry, transportation, weapons, communication, economics, urbanization, quality of life, politics, and the environment. Smil describes humanity''s energy eras in panoramic and interdisciplinary fashion, offering readers a magisterial overview. This book is an extensively updated and expanded version of Smil''s Energy in World History (1994). Smil has incorporated an enormous amount of new material, reflecting the dramatic developments in energy studies over the last two decades and his own research over that time.

How much further should the affluent world push its material consumption? Does relative dematerialization lead to absolute decline in demand for materials? These and many other questions are discussed and answered in Making the Modern World: Materials and Dematerialization. Over the course of time, the modern world has become dependent on unprecedented flows of materials. Now even the most efficient production processes and the highest practical rates of recycling may not be enough to result in dematerialization rates that would be high enough to negate the rising demand for materials generated by continuing population growth and rising standards of living. This book explores the costs of this dependence and the potential for substantial dematerialization of modern economies. Making the Modern World: Materials and Dematerialization considers the principal materials used throughout history, from wood and stone, through to metals, alloys, plastics and silicon, describing their extraction and production as well as their dominant applications. The evolving productivities of material extraction, processing, synthesis, finishing and distribution, and the energy costs and environmental impact of rising material consumption are examined in detail. The book concludes with an outlook for the future, discussing the prospects for dematerialization and potential constrains on materials. This interdisciplinary text provides useful perspectives for readers with backgrounds including resource economics, environmental studies, energy analysis, mineral geology, industrial organization, manufacturing and material science.

From the New York Times bestselling author of How the World Really Works, a wide-ranging look at the most fundamental governing principle of our world: size, whose laws, limits, and peculiarities offer the key to understanding health, wealth, and even happiness “No one writes about the great issues of our time with more rigor or erudition than Vaclav Smil.” — Elizabeth Kolbert To answer the most important questions of our age, we must understand size. Neither bacteria nor empires are immune to its laws. Measuring it is challenging, especially where complex systems like economies are concerned, yet mastering it offers rich rewards: the rise of the West, for example, was a direct result of ever more accurate and standardized measurements. Using the interdisciplinary approach that has won him a wide readership, Smil draws upon history, earth science, psychology, art, and more to offer fresh insight into some of our biggest challenges, including income inequality, the spread of infectious disease, and the uneven impacts of climate change. Size explains the regularities—and peculiarities—of the key processes shaping life (from microbes to whales), the Earth (from asteroids to volcanic eruptions), technical advances (from architecture to transportation), and societies and economies (from cities to wages). This book about the big and the small, and the relationship between them, answers the big and small questions of human existence: What makes a human society too big? What about a human being? Which alternative energy sources have the best chance of scaling and reducing our dependence on fossil fuels? Why do tall people make more money? What makes a face beautiful? How about a cathedral? How can changing the size of your plates help you lose weight? The latest masterwork of “an ambitious and astonishing polymath who swings for fences” (Wired) Size is a mind-bending journey that turns the modern world on its head.

In this book, the author takes a wide-ranging interdisciplinary look at the catastrophes and trends the next fifty years may bring. The author looks at rare but cataclysmic events, both natural and human-produced, then at trends of global importance: the transition from fossil fuels to other energy sources; demographic and political shifts in Europe, Japan, Russia, China, the United States, and Islamic nations; the battle for global primacy; and growing economic and social inequality. He also considers environmental change and assesses the often misunderstood complexities of global warming.

''My favourite author has done it again. Numbers Don''t Lie is by far his most accessible book to date, and I highly recommend it to anyone who is curious about the world. I unabashedly recommend this book to anyone who loves learning'' Bill Gates Is flying dangerous? How much do the world''s cows weigh? And what makes people happy? From Earth''s nations and inhabitants, through the fuels and foods that energize them, to the transportation and inventions of our modern world - and how all of this affects the planet itself - in Numbers Don''t Lie, Professor Vaclav Smil takes us on a fact-finding adventure, using surprising statistics and illuminating graphs to challenge lazy thinking. Smil is on a mission to make facts matter, because after all, numbers may not lie, but which truth do they convey? ''Smil''s title says it all: to understand the world, you need to follow the trendlines, not the headlines. This is a compelling, fascinating, and most important, realistic portrait of the world and where it''s going'' Steven Pinker ''The best book to read to better understand our world. It should be on every bookshelf!'' Linda Yueh ''There is perhaps no other academic who paints pictures with numbers like Smil'' Guardian Vaclav Smil is Distinguished Professor Emeritus at the University of Manitoba. He is the author of over forty books on topics including energy, environmental and population change, food production and nutrition, technical innovation, risk assessment and public policy. No other living scientist has had more books (on a wide variety of topics) reviewed in Nature. A Fellow of the Royal Society of Canada, in 2010 he was named by Foreign Policy as one of the Top 100 Global Thinkers. This is his first book for a more general readership.

From one of the world''s leading experts on the history of energy, a rigorous examination of the transitions that structure our modern world--and the environmental reckoning that will mark its success or failure. What makes the modern world work? The answer to this deceptively simple question lies in four "grand transitions" of civilization--in populations, agriculture, energy, and economics--which have transformed the way we live. Societies that have undergone all four transitions emerge into an era of radically different population dynamics, food surpluses (and waste), abundant energy use, and expanding economic opportunities. Simultaneously, in other parts of the world, hundreds of millions remain largely untouched by these developments. Through erudite storytelling, Vaclav Smil investigates the fascinating and complex interactions of these transitions. He argues that the moral imperative to share modernity''s benefits has become more acute with increasing economic inequality, but addressing this imbalance would make it exceedingly difficult to implement the changes necessary for the long-term preservation of the environment. Thus, managing the fifth transition--environmental changes from natural-resource depletion, biodiversity loss, and global warming--will determine the success or eventual failure of the grand transitions that have made the world we live in today.

World acclaimed scientist Vaclav Smil reveals everything there is to know about nature''s most sought-after resource Oil is the lifeblood of the modern world. Without it, there would be no planes, no plastic, no exotic produce, and a global political landscape few would recognise. Humanity’s dependence upon oil looks set to continue for decades to come, but what is it? Fully updated and packed with fascinating facts to fuel dinner party debate, Professor Vaclav Smil''s Oil: A Beginner''s Guide explains all matters related to the ‘black stuff’, from its discovery in the earth right through to the controversy that surrounds it today.

From the New York Times-bestselling author, a new volume on the history of human ingenuity—and its attendant breakthroughs and busts. Included in BILL GATES''s 2023 Holiday Reading List Included in Lit Hub’s Most Anticipated Books of 2023 Included in The Next Big Idea Club’s February 2023 Must-Read Books "Every Smil book that I own is marked up with lots of notes that I take while reading. Invention and Innovation is no exception. Even when I disagree with him, I learn a lot from him...he always strengthens my thinking." —Bill Gates, Gates Notes The world is never finished catching up with Vaclav Smil. In his latest and perhaps most readable book, Invention and Innovation, the prolific author—a favorite of Bill Gates—pens an insightful and fact-filled jaunt through the history of human invention. Impatient with the hype that so often accompanies innovation, Smil offers in this book a clear-eyed corrective to the overpromises that accompany everything from new cures for diseases to AI. He reminds us that even after we go quite far along the invention-development-application trajectory, we may never get anything real to deploy. Or worse, even after we have succeeded by introducing an invention, its future may be marked by underperformance, disappointment, demise, or outright harm. Drawing on his vast breadth of scientific and historical knowledge, Smil explains the difference between invention and innovation, and looks not only at inventions that failed to dominate as promised (such as the airship, nuclear fission, and supersonic flight), but also at those that turned disastrous (leaded gasoline, DDT, and chlorofluorocarbons). And finally, most importantly, he offers a “wish list” of inventions that we most urgently need to confront the staggering challenges of the twenty-first century. Filled with engaging examples and pragmatic approaches, this book is a sobering account of the folly that so often attends human ingenuity—and how we can, and must, better align our expectations with reality.

An objective, comprehensive, and accessible examination of today''s most crucial problem: preserving the environment in the face of society''s insatiable demand for energy. In Energy at the Crossroads, Vaclav Smil considers the twenty-first century''s crucial question: how to reconcile the modern world''s unceasing demand for energy with the absolute necessity to preserve the integrity of the biosphere. With this book he offers a comprehensive, accessible guide to today''s complex energy issues—how to think clearly and logically about what is possible and what is desirable in our energy future. After a century of unprecedented production growth, technical innovation, and expanded consumption, the world faces a number of critical energy challenges arising from unequal resource distribution, changing demand patterns, and environmental limitations. The fundamental message of Energy at the Crossroads is that our dependence on fossil fuels must be reduced not because of any imminent resource shortages but because the widespread burning of oil, coal, and natural gas damages the biosphere and presents increasing economic and security problems as the world relies on more expensive supplies and Middle Eastern crude oil. Smil begins with an overview of the twentieth century''s long-term trends and achievements in energy production. He then discusses energy prices, the real cost of energy, and "energy linkages"—the effect energy issues have on the economy, on quality of life, on the environment, and in wartime. He discusses the pitfalls of forecasting, giving many examples of failed predictions and showing that unexpected events can disprove complex models. And he examines the pros and cons not only of fossil fuels but also of alternative fuels such as hydroenergy, biomass energy, wind power, and solar power. Finally, he considers the future, focusing on what really matters, what works, what is realistic, and which outcomes are most desirable.

Every human activity entails the conversion of energy. Changes in the fundamental sources of energy, and in the use of energy sources, are a basic dimension of the evolution of society. Our appreciation of the significance of these processes is essential to a fuller understanding of world history. Vaclav Smil offers a comprehensive look at the role

An overview of the state of manufacturing in America—both past and present—and how this sector and the jobs it creates are essential to the American economy “There''s no author whose books I look forward to more than Vaclav Smil.” —Bill Gates In Made in the USA, Vaclav Smil powerfully rebuts the notion that manufacturing is a relic of predigital history and that the loss of American manufacturing is a desirable evolutionary step toward a pure service economy. Smil argues that no advanced economy can prosper without a strong, innovative manufacturing sector and the jobs it creates. Smil explains how manufacturing became a fundamental force behind America’s economic, strategic, and social dominance. He describes American manufacturing’s rapid rise at the end of the nineteenth century, its consolidation and modernization between the two world wars, its role as an enabler of mass consumption after 1945, and its recent decline. Some economists argue that shipping low-value jobs overseas matters little because the high-value work remains in the United States. But, asks Smil, do we want a society that consists of a small population of workers doing high-value-added work and masses of unemployed? Smil assesses various suggestions for solving America’s manufacturing crisis, including lowering corporate tax rates, promoting research and development, and improving public education. Will America act to preserve and reinvigorate its manufacturing? It is crucial to our social and economic well-being; but, Smil warns, the odds are no better than even.

A comprehensive, systematic, analytically unified, and interdisciplinary treatment of energy in nature and society, from solar radiation and photosynthesis to our fossil fuelled civilization and its environmental consequences. Energy in Nature and Society is a systematic and exhaustive analysis of all the major energy sources, storages, flows, and conversions that have shaped the evolution of the biosphere and civilization. Vaclav Smil uses fundamental unifying metrics (most notably for power density and energy intensity) to provide an integrated framework for analyzing all segments of energetics (the study of energy flows and their transformations). The book explores not only planetary energetics (such as solar radiation and geomorphic processes) and bioenergetics (photosynthesis, for example) but also human energetics (such as metabolism and thermoregulation), tracing them from hunter-gatherer and agricultural societies through modern-day industrial civilization. Included are chapters on heterotrophic conversions, traditional agriculture, preindustrial complexification, fossil fuels, fossil-fueled civilization, the energetics of food, and the implications of energetics for the environment. The book concludes with an examination of general patterns, trends, and socioeconomic considerations of energy use today, looking at correlations between energy and value, energy and the economy, energy and quality of life, and energy futures. Throughout the book, Smil chooses to emphasize the complexities and peculiarities of the real world, and the counterintuitive outcomes of many of its processes, over abstract models. Energy in Nature and Society provides a unique, comprehensive, single-volume analysis and reference source on all important energy matters, from natural to industrial energy flows, from fuels to food, from the Earth''s formation to possible energy futures, and can serve as a text for courses in energy studies, global ecology, earth systems science, biology, and chemistry.

An investigation of the America-Rome analogy that goes deeper than the facile comparisons made on talk shows and in glossy magazine articles. America''s post–Cold War strategic dominance and its pre-recession affluence inspired pundits to make celebratory comparisons to ancient Rome at its most powerful. Now, with America no longer perceived as invulnerable, engaged in protracted fighting in Iraq and Afghanistan, and suffering the worst economic downturn since the Great Depression, comparisons are to the bloated, decadent, ineffectual later Empire. In Why America Is Not a New Rome, Vaclav Smil looks at these comparisons in detail, going deeper than the facile analogy-making of talk shows and glossy magazine articles. He finds profound differences. Smil, a scientist and a lifelong student of Roman history, focuses on several fundamental concerns: the very meaning of empire; the actual extent and nature of Roman and American power; the role of knowledge and innovation; and demographic and economic basics—population dynamics, illness, death, wealth, and misery. America is not a latter-day Rome, Smil finds, and we need to understand this in order to look ahead without the burden of counterproductive analogies. Superficial similarities do not imply long-term political, demographic, or economic outcomes identical to Rome''s.

China has a population of 1.3 billion people which puts strain on her natural resources. This volume, by one of the leading scholars on the earth''s biosphere, is the result of a lifetime of study, and provides the fullest account yet of the environmental challenges that China faces. The author examines China''s energy resources, their uses, impacts and prospects, from the 1970s oil crisis to the present day, before analysing the key question of how China can best produce enough food to feed its enormous population.

Der weltbekannte Wissenschaftler Vaclav Smil analysiert das kritische Thema der nachhaltigen Ressourcennutzung, das für Forschung und Politik von großem Interesse ist Im Laufe der Zeit ist die moderne Welt von Materialströmen in ungeahntem Ausmaß abhängig geworden. Selbst die effizientesten Produktionsverfahren und ein größtmöglicher Recyclinganteil reichen möglicherweise nicht aus, um die Dematerialisierung so weit voranzutreiben, dass sie die zunehmende Nachfrage nach Materialien ausgleichen könnte, die aus dem anhaltenden Bevölkerungswachstum und steigenden Lebensstandards entsteht. In Materials and Dematerialization werden die wichtigsten Materialien der Geschichte betrachtet, von Holz und Stein über Metalle und Legierungen bis zu Kunststoffen und Silizium, mit einer Beschreibung ihrer Gewinnung bzw. Herstellung und der wichtigsten Anwendungen. In einer detaillierten Analyse werden die steigende Produktivität bei der Gewinnung und Verarbeitung, Synthese, Veredelung und Verteilung von Materialien sowie die Energiekosten und die Umweltauswirkungen des zunehmenden Materialverbrauchs untersucht. Gleichzeitig wird die Beziehung zwischen sozioökonomischer Entwicklung und Ressourcennutzung insbesondere in Bezug auf die wichtigsten Technologien und Innovationen betrachtet. Das Buch endet mit einem Ausblick auf die Zukunft. Erörtert werden dabei die Möglichkeiten der Dematerialisierung, eine mögliche Beschränkung von Materialien und eine aktualisierte Einschätzung des Materialbedarfs sowie die Prognosen für die nächsten Jahrzehnte. Nach dem großen Erfolg seiner Veröffentlichung von 2013 hat Vaclav Smil sein wegweisendes Werk nun gründlich überarbeitet. In der neuen Ausgabe werden die Fortschritte der letzten zehn Jahren herausgestellt, und auch die Statistiken und Literaturhinweise wurden auf den Stand von 2022 gebracht.

Accurate, balanced AND imaginative.Jesse H. Anusubel, Director, Program for the Human Environment, The Rockefeller University

An interdisciplinary and quantitative account of human claims on the biosphere''s stores of living matter, from prehistoric hunting to modern energy production. The biosphere—the Earth''s thin layer of life—dates from nearly four billion years ago, when the first simple organisms appeared. Many species have exerted enormous influence on the biosphere''s character and productivity, but none has transformed the Earth in so many ways and on such a scale as Homo sapiens. In Harvesting the Biosphere, Vaclav Smil offers an interdisciplinary and quantitative account of human claims on the biosphere''s stores of living matter, from prehistory to the present day. Smil examines all harvests—from prehistoric man''s hunting of megafauna to modern crop production—and all uses of harvested biomass, including energy, food, and raw materials. Without harvesting of the biomass, Smil points out, there would be no story of human evolution and advancing civilization; but at the same time, the increasing extent and intensity of present-day biomass harvests are changing the very foundations of civilization''s well-being. In his detailed and comprehensive account, Smil presents the best possible quantifications of past and current global losses in order to assess the evolution and extent of biomass harvests. Drawing on the latest work in disciplines ranging from anthropology to environmental science, Smil offers a valuable long-term, planet-wide perspective on human-caused environmental change.

A realistic yet encouraging look at how society can change in ways that will allow us to feed an expanding global population. This book addresses the question of how we can best feed the ten billion or so people who will likely inhabit the Earth by the middle of the twenty-first century. He asks whether human ingenuity can produce enough food to support healthy and vigorous lives for all these people without irreparably damaging the integrity of the biosphere. What makes this book different from other books on the world food situation is its consideration of the complete food cycle, from agriculture to post-harvest losses and processing to eating and discarding. Taking a scientific approach, Smil espouses neither the catastrophic view that widespread starvation is imminent nor the cornucopian view that welcomes large population increases as the source of endless human inventiveness. He shows how we can make more effective use of current resources and suggests that if we increase farming efficiency, reduce waste, and transform our diets, future needs may not be as great as we anticipate. Smil''s message is that the prospects may not be as bright as we would like, but the outlook is hardly disheartening. Although inaction, late action, or misplaced emphasis may bring future troubles, we have the tools to steer a more efficient course. There are no insurmountable biophysical reasons we cannot feed humanity in the decades to come while easing the burden that modern agriculture puts on the biosphere.

The period between 1867 and 1914 remains the greatest watershed in human history since the emergence of settled agricultural societies: the time when an expansive civilization based on synergy of fuels, science, and technical innovation was born. At its beginnings in the 1870s were dynamite, the telephone, photographic film, and the first light bulbs. Its peak decade - the astonishing 1880s - brought electricity - generating plants, electric motors, steam turbines, the gramophone, cars, aluminum production, air-filled rubber tires, and prestressed concrete. And its post-1900 period saw the first airplanes, tractors, radio signals and plastics, neon lights and assembly line production. This book is a systematic interdisciplinary account of the history of this outpouring of European and American intellect and of its truly epochal consequences. It takes a close look at four fundamental classes of these epoch-making innovations: formation, diffusion, and standardization of electric systems; invention and rapid adoption of internal combustion engines; the unprecedented pace of new chemical syntheses and material substitutions; and the birth of a new information age. These chapters are followed by an evaluation of the lasting impact these advances had on the 20th century, that is, the creation of high-energy societies engaged in mass production aimed at improving standards of living.

Energy transitions are fundamental processes behind the evolution of human societies: they both drive and are driven by technical, economic, and social changes. This title describes the history of modern society''s dependence on fossil fuels and the prospects for the transition to a nonfossil world.

Natural gas is the world’s cleanest fossil fuel; it generates less air pollution and releases less CO2 per unit of useful energy than liquid fuels or coals. With its vast supplies of conventional resources and nonconventional stores, the extension of long-distance gas pipelines and the recent expansion of liquefied natural gas trade, a truly global market has been created for this clean fuel. Natural Gas: Fuel for the 21st Century discusses the place and prospects of natural gas in modern high-energy societies. Vaclav Smil presents a systematic survey of the qualities, origins, extraction, processing and transportation of natural gas, followed by a detailed appraisal of its many preferred, traditional and potential uses, and the recent emergence of the fuel as a globally traded commodity. The unfolding diversification of sources, particularly hydraulic fracturing, and the role of natural gas in national and global energy transitions are described. The book concludes with a discussion on the advantages, risks, benefits and costs of natural gas as a leading, if not dominant, fuel of the 21st century. This interdisciplinary text will be of interest to a wide readership concerned with global energy affairs including professionals and academics in energy and environmental science, policy makers, consultants and advisors with an interest in the rapidly-changing global energy industry.

The magnitude and rapidity of global environmental change threatens the perpetuation of life on Earth. Many aspects of this crisis are familiar to us - the destruction of tropical rainforests, the hole in the Antarctic ozone, desertification, soil erosion - yet we avoid the underlying challenge of a rapidly deteriorating ecological system and the breadth and complexity of responses demanded. Integrating an analysis of both social and environmental needs, the book explores the premises and problems of different paths towards global management. With its emphasis on flexible response, Global Ecology furthers our understanding of biospheric change and of our abilities and weaknesses in managing the transition to a sustainable society.

A comprehensive overview of Earth''s biosphere, written with scientific rigor and essay-like flair. In his latest book, Vaclav Smil tells the story of the Earth''s biosphere from its origins to its near and long-term future. He explains the workings of its parts and what is known about their interactions. With essay-like flair, he examines the biosphere''s physics, chemistry, biology, geology, oceanography, energy, climatology, and ecology, as well as the changes caused by human activity. He provides both the basics of the story and surprising asides illustrating critical but often neglected aspects of biospheric complexity. Smil begins with a history of the modern idea of the biosphere, focusing on the development of the concept by Russian scientist Vladimir Vernadsky. He explores the probability of life elsewhere in the universe, life''s evolution and metabolism, and the biosphere''s extent, mass, productivity, and grand-scale organization. Smil offers fresh approaches to such well-known phenomena as solar radiation and plate tectonics and introduces lesser-known topics such as the quarter-power scaling of animal and plant metabolism across body sizes and metabolic pathways. He also examines two sets of fundamental relationships that have profoundly influenced the evolution of life and the persistence of the biosphere: symbiosis and the role of life''s complexity as a determinant of biomass productivity and resilience. And he voices concern about the future course of human-caused global environmental change, which could compromise the biosphere''s integrity and threaten the survival of modern civilization.

The first systematic, quantitative appraisal of power density, offering detailed reviews of power densities of renewable energy flows, fossil fuels, and all common energy uses. “There''s no author whose books I look forward to more than Vaclav Smil.” —Bill Gates In this book, Vaclav Smil argues that power density is a key determinant of the nature and dynamics of energy systems. Any understanding of complex energy systems must rely on quantitative measures of many fundamental variables. Power density—the rate of energy flux per unit of area—is an important but largely overlooked measure. Smil provides the first systematic, quantitative appraisal of power density, offering detailed reviews of the power densities of renewable energy flows, fossil fuels, thermal electricity generation, and all common energy uses. Smil shows that careful quantification, critical appraisals, and revealing comparisons of power densities make possible a deeper understanding of the ways we harness, convert, and use energies. Conscientious assessment of power densities, he argues, proves particularly revealing when contrasting the fossil fuel–based energy system with renewable energy conversions. Smil explains that modern civilization has evolved as a direct expression of the high power densities of fossil fuel extraction. He argues that our inevitable (and desirable) move to new energy arrangements involving conversions of lower-density renewable energy sources will require our society—currently dominated by megacities and concentrated industrial production—to undergo a profound spatial restructuring of its energy system.

"Vaclav Smil is my favorite author."—Bill Gates An indispensable analysis of how the world really produces and consumes its food—and a scientist''s exploration of how we can successfully feed a growing population without killing the planet We have never had to feed as many people as we do today. And yet, we misunderstand the essentials of where our food really comes from, how our dietary requirements shape us, and why this impacts our planet in drastic ways. As a result, in our economic, political, and everyday choices, we take for granted and fail to prioritize the thing that makes all our lives possible: food. In this ambitious, myth-busting book, Smil investigates many of the burning questions facing the world today: why are some of the world’s biggest food producers also the countries with the most undernourished populations? Why do we waste so much food and how can we solve that? Could the whole planet go vegan and be healthy? Should it? He explores the global history of food production to understand why we farm some animals and not others, why most of the world’s calories come from just a few foodstuffs, and how this might change in the future. How to Feed the World is the data-based, rigorously researched guide that offers solutions to our broken global food system.

Dr. Smil is the world''s authority on nitrogenous fertilizer. The industrial synthesis of ammonia from nitrogen and hydrogen has been of greater fundamental importance to the modern world than the invention of the airplane, nuclear energy, space flight, or television. The expansion of the world''s population from 1.6 billion people in 1900 to today''s six billion would not have been possible without the synthesis of ammonia. In Enriching the Earth, Vaclav Smil begins with a discussion of nitrogen''s unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts to expand natural nitrogen flows through mineral and synthetic fertilizers. The core of the book is a detailed narrative of the discovery of ammonia synthesis by Fritz Haber—a discovery scientists had sought for over one hundred years—and its commercialization by Carl Bosch and the chemical company BASF. Smil also examines the emergence of the large-scale nitrogen fertilizer industry and analyzes the extent of global dependence on the Haber-Bosch process and its biospheric consequences. Finally, it looks at the role of nitrogen in civilization and, in a sad coda, describes the lives of Fritz Haber and Carl Bosch after the discovery of ammonia synthesis.

Reality: Comprehensive energy transitions take several generations. --

As China strives to significantly increase its economic output, the nation faces an acute deterioration of the physical resources from which this prodigious growth springs. Major problems include water shortages, the pollution of water, high levels of carcinogens in the air, accelerating erosion, and industrial pollution. Originally published in 1984, Vaclav Smil documents and evaluates China’s environmental crisis. This title will be of particular interest for students of Environmental Studies and Development Studies.

Although the last two generations have seen an enormous amount of attention paid to advances in electronics, the fact remains that high-income, high-energy societies could thrive without microchips, etc., but, by contrast, could not exist without steel. Because of the importance of this material to comtemporary civilization, a comprehensive resource is needed for metallurgists, non-metallurgists, and anyone with a background in environmental studies, industry, manufacturing, and history, seeking a broader understanding of the history of iron and steel and its current and future impact on society. Given its coverage of the history of iron and steel from its genesis to slow pre-industrial progress, revolutionary advances during the 19th century, magnification of 19th century advances during the past five generations, patterns of modern steel production, the ubiquitous uses of the material, potential substitutions, advances in relative dematerialization, and appraisal of steel''s possible futures, Still the Iron Age: Iron and Steel in the Modern World by world-renowned author Vaclav Smil meets that need. - Incorporates an interdisciplinary discussion of the history and evolution of the iron- and steel-making industry and its impact on the development of the modern world - Serves as a valuable contribution because of its unique perspective that compares steel to technological advances in other materials, perceived to be important - Discusses how we can manufacture smarter rather than deny demand - Explores future opportunities and new efforts for sustainable development in the industry
