Book Description
This book presents a global and historical perspective of energy flows during the last millennium. The search for sustainable energy is a key issue dominating today’s energy regime. This book details the historical evolution of energy, following the overlapping and slow flowing transitions from one regime to another. In doing so it seeks to provide insight into future energy transitions and the means of utilizing sustainable energy sources to reduce humanity’s fossil fuel footprint. The book begins with an examination of the earliest and most basic forms of energy use, namely, that of humans metabolizing food in order to work, with the first transition following the domestication and breeding of horses and other animals. The book also examines energy sources key to development during the industrialization and mechanization, such as wood and coal, as well as more recent sources, such as crude oil and nuclear energy. The book then assesses energy flows that are at the forefront of sustainability, by examining green sources, such as solar, wind power and hydropower. While it is easy to see energy flows in terms of “revolutions,” transitions have taken centuries to evolve, and transitions are never fully global, as, for example, wood remains the primary fuel source for cooking in much of the developing world. This book not only demonstrates the longevity of energy transitions but also discusses the possibility for reducing transition times when technological developments provide inexpensive and safe energy sources that can reduce the dependency on fossil fuels. This book will be of great interest to students and scholars of energy transitions, sustainable energy and environmental and energy history.

Book Description
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.

Book Description
From the life experiences of a career teacher with a spiritual bent comes a how to book making the case for living a balanced life. Maintaining this balance is achieved through a conscious effort to keep your energy flowing freely. Your energy can be blocked in many ways, and it is important to identify the sources of blocked energy and to restore your balance. With restored balance comes a healthier, happier, and more harmonious life. An energy imbalance caused from blocked energy leads to dis-ease. If this happens over a long period of time, it becomes a destructive force. This can lead to mental and physical problems. Releasing blocked energy allows a free flow of energy. By unblocking your energy flow, you will have enhanced creativity, better relationships, a positive energized outlook, and a healthier life. This book describes how to raise your awareness and how to take steps to identify and release your blocked energy.

Book Description
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.
