| Summary: | This study explores the potential of renewable energy in Owerri Municipal, Nigeria, using Geographic Information Systems (GIS) to identify optimal locations for renewable energy projects. The objective is to contribute to sustainable energy development by assessing the spatial distribution of renewable energy resources, evaluating environmental and socio-economic factors, and generating suitability maps for various renewable energy technologies. This was achieved by integrating GIS-based analysis with comprehensive data on solar radiation and Land Use Land Cover (LULC) types. Classifying LULC was a critical step in remote sensing, offering insights into various land cover classes' spatial distribution and dynamics. An aspect model was employed to determine slope orientation with maximum solar exposure. Proximity to road networks and grid stations in Owerri Municipal was also analyzed to identify the most accessible and motorable locations. Land surface temperature (LST), a measure of the earth's surface temperature, was also examined using data from the thermal Band-10 of the Landsat 8 OLI satellite. Combining these datasets and applying the weighted overlay tool, this research identified locations with the highest potential for renewable energy generation while minimizing negative environmental and socio-economic impacts. The results aim to assist policymakers, investors, and project developers in making informed decisions regarding renewable energy projects in Owerri Municipal and serve as a valuable reference for similar initiatives in other regions. |
