This paper empirically assesses energy efficiency (EE) adoption among firms by examining the factors that drive investment in EE in the Onitsha plastic cluster, South-East, Nigeria.


Self-administered questionnaires were delivered to the selected enterprises. A total of 450 questionnaires were administered of which 423 were certified valid and used for the analysis. A Heckit model was developed and estimated.


Gender, firm size, Joneses effect and expected cost reduction benefits are the significant determinants of EE investment. However, firm structure, government incentives, regulatory requirements and reduction of carbon emission are insignificant drivers of EE investment decisions in the Onitsha plastic cluster.


This paper presents a foremost attempt at analysing the determinants of energy investment in a cluster in Nigeria.



The paper benefited from the critical inputs of the participants of the 11th International Conference of the Nigeria Association of Energy Economics held in Abuja from 22nd–24th April 2018, and Seminar organised by the Department of Economics, Nnamdi Azikiwe University Awka on the 26th June, 2019. The editors and reviewers of this journal are also commended for their detailed insights.
