Popis: Kosovo has limited renewable energy resources and its power generationsector is based on fossil fuels. Such a situation emphasizes the importance ofactive research and efficient use of renewable energy potential. According tothe analysis of meteorological data for Kosovo, it can be concluded thatamong the most attractive potential wind power sites are the locations knownas Kitka (42° 29' 41" N and 21° 36' 45" E) and Koznica (42° 39′ 32″ N, 21°22′30″E). The two terrains in which the analysis was carried out aremountain areas, with altitudes of 1142 m (Kitka) and 1230 m (Koznica). Thesame measuring height, about 84 m above the ground, is obtained for theseaverage wind speeds: Kitka 6,667 m/s and Koznica 6,16 m/s. Since the difference in wind speed is quite large versus a difference in altitude that isnot being very large, analyses are made regarding the terrain characteristicsincluding the terrain relief features. In this paper it will be studied how muchthe roughness of the terrain influences the output energy. Also, that theassumption to be taken the same as to how much they will affect the annualenergy produced.
