The book chapter examines the various facets of wave energy, including resource quantification and wave measurement, the wide variety of onshore and offshore wave energy devices, the variety of power take-off (PTO) mechanisms which convert wave power into other useful forms and concluding with some insight to how wave energy devices are modelled and controlled.
