Abstract: The negative effects of traditional methods ofelectricity generation on the environment have created the need for strategicplanning and development of renewable and sustainable energy systems. Thispaper presents the analysis of the suitability of wind farm sites using a Booleandecision-making approach based on geographicinformation system (GIS) modeling. This analysis is based on differentclimatic, geographical, economic and environmental criteria such as wind resource, slope, accessibility by road,proximity to the electricity network and optimal distance from airports.The results of the study show that the most favorable sites are mainly locatedin the northern part of the country, particularly in the Far North and Northregions. There are also favorable sites inthe North-West, South-West, West, Littoral and very little in the Southwhile the central and eastern regions are not suitable. This is mainly due tothe tropical forest that covers the entire region of East Cameroon and the lowwind speed in these regions which is the determining factor for theinstallation of wind farms. The appropriate land for the installation of wind farms is approximately2.56 corresponding to an area of 11,602.494414 km2. However, when we include the condition that a wind farmmust have at least 4 km2 of surface area, is goes from 2.56 to 2.22 (11,602.494414 km2 to 10,344.424539km2); thus asurface reduction of approximately 1258.069875 km2. We can conclude that despite the fact that Cameroon does not have ahuge potential for wind energy because of the low wind speed observed in thecountry, it is still possible to have some favorable sites for the installationof the parks wind. In addition, a study of hybrid solar-wind systems couldimprove the efficiency of the power plants in Cameroon.
