#### 3.3.1. Wind Power Sources

In Nigeria, coastal, mountainous, and offshore sites are endowed with huge wind power resources. The wind speed over the complex landscapes and the plain surface ranges between 3.60 and 5.40 m per second in the north, whereas the south is characterized by small wind resources with speeds ranging between 1.4 to 3.0 m per second. The wind speed (WS) information obtained from the NASA Prediction of Worldwide Energy Resources (POWER) database [63] over thirty years is given in Table 5. The wind data show that there is a great change in the wind speed reported from November to March of each year in the different locations. Observation of the wind speed information reveals that the minimum and maximum wind speeds are reported in different months due to distinctions in the geographical characteristics and climatic conditions of each site. The lowest wind speed recorded in Sokoto is 3.78 m/s (September), while those of Ikeja, Enugu, Port-Harcourt, Maiduguri, and Minna were obtained at 2.65 m/s (December), 2.83 m/s (November), 2.43 m/s (December), 3.96 m/s (September), and 2.75 m/s (October), respectively. Furthermore, the highest average wind speed values of 7.25 m/s (January), 4.9 m/s (August), 5.03 m/s (August), 4.0 m/s (August), 7.12 m/s (February), and 5.69 m/s (January) were reported in Sokoto, Ikeja, Enugu, Port-Harcourt, Maiduguri and Minna, respectively with a yearly average of 5.44 m/s, 3.81 m/s, 4.09 m/s, 3.15 m/s, 5.50 m/s, and 3.97 m/s, respectively.
