Chapter 10 Comparison of Wave Energy and Offshore Wind Laura Castro-Santos and Félix Puime Guillén Abstract The aim of this chapter is to compare wave energy and offshore wind energy in economic terms. The future of energy and electricity production will be at ocean. In this sense, offshore wind and wave energy are the two main important offshore renewable energies. However, it is important to compare them in economic terms to calculate their feasibility in order to take strategic decisions. In this context, aspects such as the LCOE are calculated to provide an economic comparison of these two technologies. The methodology will be carried out for a particular case of study. The location selected for this purpose has the offshore wind resource, and the wave energy resource is very good: It is the region of Galicia (located in the northwest of Spain). Results indicate the best ocean renewable energy in economic terms. This comparison is useful for future considerations in order to select the best location for an offshore renewable energy farm. Keywords Wave energy · Offshore wind · Feasibility · Ocean energy · Renewable energy 10.1 Introduction When talking about renewable energy, it is important to point out that in addition to the important advantages that these have over other types of energy, such as that they do not generate polluting gases, or waste, their use is infinite and that they generate by investment many more jobs than other alternative sources. However, it is important to bear in mind that they may also have disadvantages for their development since in their initial phase, the one corresponding to the investment, the profitability for L.
