Locating appropriate sites where wind farms can be established requires a powerful spatial decision-making framework that considers technical, environmental, climatic and socio-economic aspects. Despite the fact that the interest in renewable energy in Iraq is growing, there are no prior works that have considered the suitability of wind farms in the Basra Governorate with the help of a Multi-Criteria Decision-Making (MCDM) approach based on the Analytic Hierarchy Process (AHP) methodology. The current study fills this gap by developing an AHP-based spatial evaluation model to include the necessary criteria used to identify the best locations of wind power installations. The disciplines of environmental science, geographic information systems and renewable energy are used to arrive at expert judgment that is reflected in pairs of comparison matrices through which criterion weights are derived after consistency has been ensured. It is found that the climatic factors have the strongest impact on the site suitability by 56.2%. This indicates that climatic variables play a critical role in regulating the efficiency in energy production. Geomorphological features are next in significance by 17.4%, Economic factor by 18.3% and environmental factor by 8.1%. Collectively, these results are a complete spatial decision support system that can be used by policy-makers and developers to plan wind farms projects in Basra and other similar areas.
