From an expert who advised on the Chernobyl problem as well as in the aftermath of Three Mile Island comes a book that contains experienced engineering assessments of the options for replacing the existing, aged, fossil-fired power stations by renewables, gas-fired, or nuclear plants. From geothermal, solar, and wind to tidal and hydro generation, this important book assesses the engineering of renewable sources for commercial generation and discusses the important aspects of the design, operation, and safety of nuclear stations.
