Found in rushing rivers and the churning waters of the ocean, hydro and wave energy technologies turn the movement of water into useful electricity. The Science of Hydro and Wave Energy examines the fields of hydroelectric and ocean energy technologies, including the underlying scientific concepts, their potential for replacing fossil fuels, examples of how they are used today, and prospective future developments.
