The thesis provides an overview of power take-off systems used in wave energy converters with descriptions of wave energy device concepts. Wave energy potential of the Gulf of Trieste is assessed based on the data obtained from the Vida buoy placed in the vicinity of Slovenian coast. All of the calculations and the final assessment are based on the linear wave theory, where results are compared to other energy resources in the country of Slovenia and the future of renewable energy is discussed. Performed calculations indicated that low to moderate sea states in the Gulf of Trieste at the current state of the wave energy converters technology, provide significantly lower amount of electrical energy compared with other renewable energy resources.
