Strategies for reducing the costs of clean-energy technologies in buildings in Nigeria

Abstract

AbstractThe costs of clean-energy technologies are currently very high and their adoption in buildings is voluntary. This study evaluated strategies for improving the cost performance of photovoltaic (PV) electricity applied in buildings in Nigeria using a questionnaire survey involving 415 targets. The efficacy of each strategy and consensus in respondents’ perceptions were determined using Fuzzy Set Theory and Kruskal–Wallis tests. The top four strategies for achieving PV-cost reduction are mandating green buildings, standardization of building designs and PV components, facilitating import licensing and massive public education. Developing these strategies to improve the PV value chain will increase the supply capacity of clean energy in emerging markets.
