DOWNLOAD EBOOKCoal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

DOWNLOAD EBOOKWorld 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.
