Bøker av Vaclav (Distinguished Professor Emeritus Smil

Creating and Transforming the Twentieth Century combines two of Vaclav Smil's seminal works--Creating the Twentieth Century and Transforming the Twentieth Century--in this revised and expanded edition. Covering technical advances that shaped the period from 1867 through the end of the 20th century, this new edition contains numerous updates and features a new preface and a final chapter examining key themes in light of major 21st-century events and publications. Now in a single volume, these classic texts remain central to Smil's acclaimed oeuvre, and their lessons are perennially fascinating.

A comprehensive overview of Earth's biosphere, written with scientific rigor and essay-like flair.

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. Vaclav Smil is Distinguished Professor at the University of Manitoba and the author of many books, including Energy at the Crossroads (2003), The Earth's Biosphere: Evolution, Dynamics, and Change (2002), and Energies: An Illustrated Guide to the Biosphere and Civilization (1998), all of which are published by The MIT Press.

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.
