La fascinante historia de la civilización a traves del prisma de la energía.La energía es la única moneda de cambio universal. Sin transformación de energía, no hay nada. La vida en la Tierra depende de la conversion de la energia solar en biomasa vegetal, mientras que los seres humanos hemos aprendido a utilizar otros flujos de energia, como los combustibles fosiles o la generacion fotovoltaica de electricidad.En esta monumental historia, Vaclav Smil ofrece una impresionante panoramica de como la energia ha impulsado el progreso cultural y economico de las sociedades humanas durante los ultimos diez mil años, desde los primeros grupos de cazadores-recolectores hasta la civilizacion fosil, pasando por las sociedades agricolas tradicionales y la "gran transicion" que lo cambio todo.Energia y civilizacion es la gran obra maestra de Vaclav Smil, "el mayor experto mundial en el ambito de la energia" segun la revista Science. Una lectura fascinante en la que se habla de todo: agricultura, transporte, construccion, economia, ecologia, guerra, tipos de carbon, petroleo, electricidad, hornos, motores, piramides y mucho mas.

There is no author whose books I look forward to more than Vaclav Smil' Bill Gates__________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 perils 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, making their complete and rapid elimination unlikely. For example, each greenhouse-grown supermarket-bought tomato requires the equivalent of five tablespoons of diesel oil for its production; and we still lack any commercially viable ways of making steel, ammonia, cement or plastics on the scale required globally without fossil fuels.Vaclav Smil is neither a pessimist nor an optimist, he is a scientist; he is the world-leading expert on energy and an astonishing polymath. This is his magnum opus and a continuation of his quest to make facts matter. Drawing on the latest science, including his own fascinating research, and tackling sources of misinformation head on - from Yuval Noah Harari to Noam Chomsky - 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 masterpiece 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.__________'Very informative and eye-opening in many ways' Ha-Joon Chang, author of 23 Things They Don't Tell You About Capitalism'If you are anxious about the future, and infuriated that we aren't doing enough about it, please read this book' Paul Collier, author of The Future of Capitalism

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 Now a fifth transition is underway the environmental changes that will determine the success or eventual failure of the preceding transitions that have made the world we inhabit today

This book offers a comprehensive look at the role of energy in world history, ranging from human muscle-power in foraging societies and animal-power in traditional farming to preindustrial hydraulic techniques and modern fossil-fueled civilization.

Este libro aborda el problema de cómo se podrán producir suficientes alimentos para nutrir a los 10.000 millones de personas que previsiblemente habitarán la Tierra a mediados del siglo XXI. El autor, adoptando un enfoque cientifico, no se suma ni a la vision catastrofista segun la cual es inminente una hambruna generalizada, ni a la vision optimista, que da por buenos grandes incrementos de poblacion como fuente de inagotable inventiva humana.

The story of how diesel engines and gas turbines, used to power cargo ships and jet airplanes, made todays globally integrated economy possible.The many books on globalization published over the past few years range from claims that the world is flat to an unlikely rehabilitation of Genghis Khan as a pioneer of global commerce. Missing from these accounts is a consideration of the technologies behind the creation of the globalized economy. What makes it possible for us to move billions of tons of raw materials and manufactured goods from continent to continent? Why are we able to fly almost anywhere on the planet within twenty-four hours? In Prime Movers of Globalization, Vaclav Smil offers a history of two key technical developments that have driven globalization: the high-compression non-sparking internal combustion engines invented by Rudolf Diesel in the 1890s and the gas turbines designed by Frank Whittle and Hans-Joachim Pabst von Ohain in the 1930s. The massive diesel engines that power cargo ships and the gas turbines that propel jet engines, Smil argues, are more important to the global economy than any corporate structure or international trade agreement. Smil compares the efficiency and scale of these two technologies to prime movers of the past, including the sail and the steam engine. The lengthy processes of development, commercialization, and diffusion that the diesel engine and the gas turbine went through, he argues, provide perfect examples of gradual technical advances that receive little attention but have resulted in epochal shifts in global affairs and the global economy.

An interdisciplinary and quantitative account of human claims on the biospheres stores of living matter, from prehistoric hunting to modern energy production.The biospherethe Earths thin layer of lifedates from nearly four billion years ago, when the first simple organisms appeared. Many species have exerted enormous influence on the biospheres 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 biospheres stores of living matter, from prehistory to the present day. Smil examines all harvestsfrom prehistoric mans hunting of megafauna to modern crop productionand 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 civilizations 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 wide-ranging, interdisciplinary look at global changes that may occur over the next fifty yearswhether sudden and cataclysmic world-changing events or gradually unfolding trends.Fundamental change occurs most often in one of two ways: as a fatal discontinuity, a sudden catastrophic event that is potentially world changing, or as a persistent, gradual trend. Global catastrophes include volcanic eruptions, viral pandemics, wars, and large-scale terrorist attacks; trends are demographic, environmental, economic, and political shifts that unfold over time. In this provocative book, scientist Vaclav Smil takes a wide-ranging, interdisciplinary look at the catastrophes and trends the next fifty years may bring.Smil first looks at rare but cataclysmic events, both natural and human-produced, then at trends of global importance, including the transition from fossil fuels to other energy sources and growing economic and social inequality. He also considers environmental changein some ways an amalgam of sudden discontinuities and gradual changeand assesses the often misunderstood complexities of global warming.Global Catastrophes and Trends does not come down on the side of either doom-and-gloom scenarios or techno-euphoria. Instead, Smil argues that understanding change will help us reverse negative trends and minimize the risk of catastrophe.

An investigation of the America-Rome analogy that goes deeper than the facile comparisons made on talk shows and in glossy magazine articles.Americas postCold 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 basicspopulation 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 Romes.

An objective, comprehensive, and accessible examination of todays most crucial problem: preserving the environment in the face of societys insatiable demand for energy.In Energy at the Crossroads, Vaclav Smil considers the twenty-first centurys crucial question: how to reconcile the modern worlds 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 todays complex energy issueshow 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 centurys 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.

There is no author whose books I look forward to more Bill GatesA fascinating deep dive...a wonderful fact-based tour of our food system, past and present. It opens up plenty of interesting debates on what to do next to feed 10 billion people without wrecking the planet Hannah Ritchie, author of Not the End of the World In this ambitious, myth-busting book, leading scientist and internationally bestselling author Vaclav Smil investigates many of the burning questions facing the world today: Why are some of the worlds biggest food producers also the countries with the most undernourished populations? Why is food waste a colossal 1,000kcal per person daily, and how can we solve that? Could we all go vegan and be healthy? Should we? How will we feed the ballooning population without killing the planet?How to Feed the World shows how 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. Ultimately, this data-based, rigorously researched guide explains how we will survive and thrive long into the future.
