This second edition is now the definitive overview of the realities of adopting alternative energy technologies. Focusing mostly on the US situation but acknowledging that energy availability and technology choices cannot be understood apart from the international context, Simon makes an unassailable case that the world’s energy needs cannot be met without alternative energy. He points out that adoption decisions are not made in a technocratic vacuum but are instead made according to various political, economic, and social feasibilities. Explaining how the current mix of energy technologies was reached and the possibilities going forward, Simon provides a sophisticated understanding of the policy process. His analysis is comprehensive, accurate, and fair to all technologies—from the more established such as nuclear, solar, and wind to the less common, e.g., biodiesel, geothermal, and hydrogen fuel cells. Neither an advocacy book nor a book for those who want simple answers to solving the US’s (and the world’s) energy problems, this well-written resource is an impressive accomplishment. Summing Up: Essential. All readers.
