Energies 2019, 12, 3658 21 of 37 greater COV than the other regions. However, the differences between the COV values of the region C, when compared with those in the regions A and B, are small and decrease as the water depth increases from 25 to 200 m. The region C has the smallest wave power variability during the year, which may lead to a higher capacity factor, while the regions A and B are the areas with the most energetic waves, allowing the deployment of the devices with higher installed capacity. A trade-off between the WEC nominal power and capacity factor as well as other local characteristics such as water depth should be considered to determine the proper locations for deploying wave farms. 9°N Latitude 0° 9°S 18°S 27°S 10 15 0 20 35 Annual Summer Autumn 25 20 15 10 20 30 30 15 10 25 15 30 35 20 Winter Spring 10 15 15 20 25 25 20 L Wave Power (kW/m) 10 15 25 10 25 5 25 20 30 30 25 35 35 30 50°W 45°W 40°W 35°W 30°W 25°W Longitude Figure 15.

Accordingly, a total available wave power of approximately 91.8 GW was estimated considering a total coastline length of about 7491 km (an approximate value without coastline details). It should be noted that this value is an estimation of the theoretical potential of
