The demand of Americans for more and more power, particularly electric power, contrasted by the deep and growing concern for the environment and a desire by private citizens to participate in the public decisions that affect the environment is the dilemma explored in this book. Part One by John Holdren, offers a scientist's overview of the energy crisis, examining the sources and consumption of energy in the United States. He considers fossil fuels, hydroelectric energy, nuclear fission, energy use, thermal pollution, climate, tomorrow's energy supply, and some aspects of the demand, describing how production of power inevitably leaves its mark upon the environment. Part Two by Philip Herrera, reports a journalist's account of remarkable efforts by concerned citizens to protect the environment from the effects of power-activated air, water, and landscape pollution. Case studies of some of the major recent controversies over the placement and operation of power plants are given, summarizing their conflicts and resolutions. Together, the author's observations and recommendations raise hope that the United States can find a rational solution to its energy crisis. (BL)
