Energy policy in the United States and much of the analysis behind those policies is largely incomplete according to many. Systems for energy production, distribution, and use have traditionally been analyzed by supply sector, yet such analyses cannot capture the complex interplay of technology, economics, public policy, and environmental concerns that shapes energy supply. In this book, experts from diverse fields examine the evolving structure of the energy system, explore the changing patterns of supply and demand, offer insights into the forces driving the changes, and discuss energy planning strategies. Also covered are: the vulnerabilities in the energy system in the United States such as the lack of a comprehensive nuclear policy and the uncertain role of alternative fuels; the influence of technological change; and the increasing importance of the environmental aspects of energy systems; automotive emissions; pollution transport; carbon dioxide production and global warming; and the relationship among energy, ecology, and economic development.
