Coal fuels about 50 percent of US electricity production and provides a quarter of the country's total energy. China and India's ferocious economic growth is based almost entirely on coal-generated electricity. Coal currently looks like a solution to many of our fast-growing energy problems. However, while coal advocates are urging full steam ahead, increasing reliance on the dirtiest of all fossil fuels has crucial implications for the global climate, energy policy, the world economy, and geopolitics. Drawbacks to a coal-based energy strategy include: Scarcity – new studies suggest that the peak of world coal production may actually be less than two decades away. Cost – the quality of produced coal is declining, while the expense of transport is rising, leading to spiraling costs and increasing shortages. Climate impacts - our ability to deal with the historic challenge of climate change will hinge on reducing our coal consumption in future years. Blackout goes to the heart of the tough energy questions that will dominate every sphere of public policy throughout the first half of this century, and is a must-read for planners, educators, and anyone concerned about energy consumption, peak oil and climate change.
This discussion of coal highlights the changing technology of underground and surface mining, the controversial issue of land reclamation, and the importance of this fossil fuel's many by-products.

Thoroughly revised and updated edition of this comprehensive survey of resource depletion.
We are facing a global energy crisis caused by world population growth, an escalating increase in demand, and continued dependence on fossil-based fuels for generation. It is widely accepted that increases in greenhouse gas concentration levels, if not reversed, will result in major changes to world climate with consequential effects on our society and economy. This is just the kind of intractable problem that Purdue University's Global Policy Research Institute seeks to address in the Purdue Studies in Public Policy series by promoting the engagement between policy makers and experts in fields such as engineering and technology. Major steps forward in the development and use of technology are required. In order to achieve solutions of the required scale and magnitude within a limited timeline, it is essential that engineers be not only technologically-adept but also aware of the wider social and political issues that policy-makers face. Likewise, it is also imperative that policy makers liaise closely with the academic community in order to realize advances. This book is designed to bridge the gap between these two groups, with a particular emphasis on educating the socially-conscious engineers and technologists of the future. In this accessibly-written volume, central issues in global energy are discussed through interdisciplinary dialogue between experts from both North America and Europe. The first section provides an overview of the nature of the global energy crisis approached from historical, political, and sociocultural perspectives. In the second section, expert contributors outline the technology and policy issues facing the development of major conventional and renewable energy sources. The third and final section explores policy and technology challenges and opportunities in the distribution and consumption of energy, in sectors such as transportation and the built environment. The book's epilogue suggests some future scenarios in energy distribution and use.
