World Energy Resources is an explanatory energy survey of the countries and major regions of the world, their geographic and economic settings, and signif icant inter-relationships. This book attempts to combine several interacting energy themes that encompass a historical development, energy issues and forecasts, economic geography, environmental programs, and world energy use. The main thrust of this book -World Energy Resources - is based on princi ples of energy science, applied geology, geophysics, and other environmental sciences as they relate to the exploration, exploitation, and production of resources in this country and throughout the world. This work is an analysis of the United States (USA) and world oil, gas, coal, and alternative energy resources and their associated issues, forecasts, and related policy. This book could not have been attempted without a broad geological exposure and international ge ographic awareness. Much information is scattered among federal and state agencies, schools, and other institutions, and this book has attempted to com bine some of the vast information base. This attempt can only skim the infor mation surface at best, but its regional and topical coverage is broad in scope. Part I introduces conventional energy resources and their historical develop ments, and includes chapters 1 to 7. The basic concepts and supporting facts on energy sources are presented here for the general education of energy analysts, policy makers, and scientists that desire a brief review of advanced technologies and history.

This report, Coal Data: A Reference, summarizes basic information on the mining and use of coal, an important source of energy in the US. This report is written for a general audience. The goal is to cover basic material and strike a reasonable compromise between overly generalized statements and detailed analyses. The section S̀̀upplemental Figures and Tables̀̀ contains statistics, graphs, maps, and other illustrations that show trends, patterns, geographic locations, and similar coal-related information. The section C̀̀oal Terminology and Related Information ̀̀provides additional information about terms mentioned in the text and introduces some new terms. The last edition of Coal Data: A Reference was published in 1991. The present edition contains updated data as well as expanded reviews and additional information. Added to the text are discussions of coal quality, coal prices, unions, and strikes. The appendix has been expanded to provide statistics on a variety of additional topics, such as: trends in coal production and royalties from Federal and Indian coal leases, hours worked and earnings for coal mine employment, railroad coal shipments and revenues, waterborne coal traffic, coal export loading terminals, utility coal combustion byproducts, and trace elements in coal. The information in this report has been gleaned mainly from the sources in the bibliography. The reader interested in going beyond the scope of this report should consult these sources. The statistics are largely from reports published by the Energy Information Administration.

This inquiry into the technical advances that shaped the 20th century follows the evolutions of all the principal innovations introduced before 1913 (as detailed in the first volume) as well as the origins and elaborations of all fundamental 20th century advances. The history of the 20th century is rooted in amazing technical advances of 1871-1913, but the century differs so remarkably from the preceding 100 years because of several unprecedented combinations. The 20th century had followed on the path defined during the half century preceding the beginning of World War I, but it has traveled along that path at a very different pace, with different ambitions and intents. The new century's developments elevated both the magnitudes of output and the spatial distribution of mass industrial production and to new and, in many ways, virtually incomparable levels. Twentieth century science and engineering conquered and perfected a number of fundamental challenges which remained unresolved before 1913, and which to many critics appeared insoluble. This book is organized in topical chapters dealing with electricity, engines, materials and syntheses, and information techniques. It concludes with an extended examination of contradictory consequences of our admirable technical progress by confronting the accomplishments and perils of systems that brought liberating simplicity as well as overwhelming complexity, that created unprecedented affluence and equally unprecedented economic gaps, that greatly increased both our security and fears as well as our understanding and ignorance, and that provided the means for greater protection of the biosphere while concurrently undermining some of the key biophysical foundations of life on Earth. Transforming the Twentieth Century will offer a wide-ranging interdisciplinary appreciation of the undeniable technical foundations of the modern world as well as a multitude of welcome and worrisome consequences of these developments. It will combine scientific rigor with accessible writing, thoroughly illustrated by a large number of appropriate images that will include historical photographs and revealing charts of long-term trends.
