Power generation scenarios for Nigeria: An environmental and cost assessment

►The power sector in Nigeria is set to grow significantly in near future. ►Power sector scenarios are constructed and studied using LCA and economic analysis methods and then compared against the Government's plans. ►These include two fossil-fuel and two sustainable-development-driven scenarios. ►The results explicitly show the trade-offs between environmental impacts and costs. ►Following the fossil fuel paths will reduce capital costs but increase environmental impacts. The renewable energy paths will reduce some environmental impacts but increase the capital costs.
