Vaclav Smil Books

The story of how diesel engines and gas turbines, used to power cargo ships and jet airplanes, made today's globally integrated economy possible.

Addressing critical global issues, this book delves into the paradox of food production and undernourishment, the staggering amount of food waste, and the implications of a vegan diet. It challenges misconceptions about food sources and dietary needs, emphasizing their significant impact on our planet. Through rigorous research and data analysis, the author explores sustainable solutions for feeding a growing population while highlighting the urgent need for change to ensure future survival and prosperity.

"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. Materials and Dematerialization: Making the Modern World explores the costs of this dependence and the potential for substantial dematerialization of modern economies. Revised throughout to highlight advances that have taken place over the last decade, including a thorough review of statistics and references to 2022, this new edition includes new sections to explicitly address material for global energy transition and for securing food for a still growing global population. Smil concludes with an updated appraisal of material requirements and prospects during the coming decades. This interdisciplinary text will provide useful perspectives for readers with backgrounds including resource economics, environmental studies, energy analysis, mineral geology, industrial organization, manufacturing and public policy"-- Provided by publisher

A realistic yet encouraging look at how society can change in ways that will allow us to feed an expanding global population. schovat popis

Examines the Earth's biosphere, including its workings, interactions, and complexity.

The book presents a compelling argument about the complexities and lengthy nature of energy transitions, emphasizing that underestimating these factors leads to unrealistic expectations regarding the rapid reduction of fossil fuel dependency in the U.S. and other economies. It challenges prevailing narratives and explores the implications of this misunderstanding for future energy policies and global economic strategies.

The transformative period from 1867 to 1914 marked a pivotal moment in history, characterized by the rise of a civilization fueled by innovative technologies and scientific advancements. Key developments, such as the invention of dynamite, played a crucial role in shaping industries and societies. This era laid the groundwork for modernity, highlighting the synergy between energy sources and technological progress, which fundamentally altered human life and set the stage for future advancements.

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

The book highlights the critical role of ammonia synthesis in supporting global population growth, emphasizing its significance over other technological advancements like airplanes and nuclear energy. Dr. Smil, a leading expert on nitrogenous fertilizers, explores how this industrial process has fundamentally transformed agriculture and society, enabling the world’s population to expand from 1.6 billion in 1900 to six billion today.

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.
