摘要：Investment into a renewable energy project spurs theneed to investigate sites with potential for a renewable energy source. Such acrucial investigation is the main motivation for this study, which uses a geospatialtechnology to evaluate wind energy potential within the south-east andsouth-south regions of Nigeria. A multi-criteria decision analysis (MCDA) modelwas implemented using Landsat TM images at bands 2, 3and4, and integratedwith NASA global wind speed data, airport location map and forest reserve mapof the area. The criteria for generation of wind energy potential map were:wind speed ≥ 3m/s, 2000m buffer from built-up areas, 2,500m buffer fromairports and outside the forest reserve. The results indicate the presence of areasonable amount of potential for wind energy which lies mostly in thesouthernmost part of the study area. The total potential area is about 104,700hectares in land size, which is merely 1.2% of the total study area, althoughRiver state encloses most of the potential locations. When compared to globalvortex wind data, by visual inspection, these potential areas show a great dealof sensitivity to wind speed, highlighting its critical importance in thepresent modelling. Wind farms can be located in this area, although it is a rathersmall scale investment in a renewable energy resource considering that theconsumable amount of energy in the study area is in a steady increase. Stakeholders and experts in energy economy will find that the need to protect thispotential energy location from indiscriminate urban development and otheranthropogenic activities is compelling.
