When the wind speed map at a height of 100 m produced for the Balikesir Province (Figure 5) is examined, the speeds are distributed between 2.52 and 10.91 m/s. When the speed distributions are evaluated for the districts, the high-speed values in the Balya, Bandrma, Edremit, Burhaniye, Havran, and Erdek districts are greater than those in the other districts. In addition, the maximum, minimum, and average wind speeds, and standard deviations at a height of 100 m are shown according to district in Table 5. These wind speeds were derived from the wind speed maps in raster data format. Figure 8 illustrates the wind speed maps of the Ayvalik, Balya, Bandrma, and Bigadic districts at a height of 100 m. The wind speed maps of the other districts are also given in Figures 11-14 of Appendix A. Wind speed varies depending on landforms. While the friction effect of wind increases in mountainous and rough terrains, its speed decreases. On smooth surfaces, such as the sea and oceans, the wind speed increases as the friction effect decreases. When the wind speed map created is examined, it is seen that the wind speeds are generally higher on the coastline. The Ayvalik, Gomez, Burhaniye, Edremit, Gonen, Bandrma, Erdek, and Marmara districts are located on the coastline. To the west of the Ayvalik and Gomes districts, there is the island of Lesbos. Due to the roughness caused by Lesbos Island, the wind speeds in the Ayvalik and Gomes districts are lower than those in other districts on the coastline. In addition, the wind speeds in the Ivrindi and Savastepe districts are lower than those in other districts for the same reason. However, due to the air corridor formed by the passage of the Bosphorus between the Canakkale Province and  
Figure 7: Excluded areas. Lesbos Island, the wind speeds are at high levels in the districts of Burhanjye, Edremit, Havran, and Balya, which are located in this direction. Since Sundrygi, Bigadic, Dursunbey, and Kepsut are the furthest districts from the coastline, their wind speeds are lower than those of other districts. When the maximum and average wind speeds and standard deviations are examined, it is seen that Bandirma is the most favorable district in terms of wind speed. There is the Marmara Sea to the north of Bandirma and Lake Manyas to the south. Therefore, the roughness that will prevent the wind flow in the district is low. For this reason, wind speeds are at high levels throughout the district. \begin{table}

Since wind speed is the main factor in the calculation of wind power potential, the distribution of wind power potential in the districts also differs due to the reasons stated above and is parallel to the wind speed distribution.
