Anyone who watches the television news has seen images of firefighters rescuing people from burning buildings and paramedics treating bombing victims. How do these individuals make the split-second decisions that save lives? Most studies of decision making, based on artificial tasks assigned in laboratory settings, view people as biased and unskilled. Gary Klein is one of the developers of the naturalistic decision making approach, which views people as inherently skilled and experienced. It documents human strengths and capabilities that so far have been downplayed or ignored. Since 1985, Klein has conducted fieldwork to find out how people tackle challenges in difficult, nonroutine situations. Sources of Power is based on observations of humans acting under such real-life constraints as time pressure, high stakes, personal responsibility, and shifting conditions. The professionals studied include firefighters, critical care nurses, pilots, nuclear power plant operators, battle planners, and chess masters. Each chapter builds on key incidents and examples to make the description of the methodology and phenomena more vivid. In addition to providing information that can be used by professionals in management, psychology, engineering, and other fields, the book presents an overview of the research approach of naturalistic decision making and expands our knowledge of the strengths people bring to difficult tasks.

This second volume deals with power relations between the Industrial Revolution and the First World War.

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.

A landmark book rolls out a bold, new, energy-based theory of human history based on a simple, yet powerful law: whoever controls the world's effective energy supplies during a given energy age will inevitably dominate the economic, political, and cultural history of that age. The innovative theory articulated in Sources of Power: How Energy Forges Human History parses history into four ages: the foraging, agriculture, coal, and oil ages, each defined by the dominant source of power. Manfred Weissenbacher tests this sweeping theory against the panorama of world history, combining formidable powers of synthesis with a specialist's deep understanding of energy systems and technologies. After proving the operation of his law through history and into the present, Weissenbacher applies it to global geopolitical trends. He assesses the prospects of the various candidate technologies to succeed oil and charts future scenarios based on the distribution of energy reserves. Finally, he forecasts the fates of the American and Chinese empires in the twilight of the oil age: the United States as a mature superpower forced to deploy military might to occupy oilfields in the Middle East; China as an emerging superpower forced to deploy economic might to muscle in on the development of Third World oilfields.
