Energy Resources mainly focuses on energy, including its definition, historical perspective, sources, utilization, and conservation. This text first explains what energy is and what its uses are. This book then explains coal, oil, and natural gas, which are some of the common energy sources used by various industries. Other energy sources such as wind, solar, geothermal, water, and nuclear energy sources are also tackled. This text also looks into fusion energy and techniques of energy conversion. This book concludes by explaining the energy allocation and utilization crisis. This publication will be invaluable to those interested in energy science.

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.

The first comprehensive case study of railroad electrification in the United States, this pioneering book highlights a subject of current government and industry studies and a target of billions of dollars of Amtrak rehabilitation funds. Both energy conservation and environmental quality remain at stake together with transportation efficiency. Electric traction on the Pennsylvania Railroad was a technological success handicapped by an economic factor: the onetime relatively low cost of petroleum, which gave diesel locomotives and highway vehicles a temporary advantage. Today the growing cost advantage of electricity--generated with coal; atomic energy; water, wind, and solar power--prefigures a revival of electric railroad traction. Drawing upon previously untapped records of the PRR and its suppliers, notably General Electric, the author traces stages in cooperative risk management. First came challenges of limited scope which steam locomotives were unable to meet: the New York City tunnel extension of 1910 and the Philadelphia suburban modernization begun in 1913. Next came a decade of mainline electrification, 1928-38: first New York to Washington and then passenger and freight extensions to Harrisburg. These projects were preceded by large-scale research and experimentation, followed by constant improvement in equipment and operations. Electric traction is depicted as a program involving not only the railroad but also its consultants, equipment and energy suppliers, and (to a lesser degree) governmental bodies. Locomotive and power transmission design is described in detail--with copious illustrations--as are the creative achievements of managers, engineers, and workers. And the presentation will be clear to readers without specialized technical or business backgrounds.
