Energy savings opportunities at the University of Nigeria, Nsukka

Abstract

This paper examines the potential for energy savings in Nigerian higher institutions with particular reference to the University of Nigeria, Nsukka. Electricity consumption and cost profiles for a period of 10 years indicate a steady rise attributable to marginal improvement in staff living standards, increasing students’ enrolment, infrastructural development, preponderant use of inefficient electrical appliances and increasing business activities within the community. Investigations show that about 51% of the total electricity consumption occurs in staff housing units, 16% in students’ hostels and the balance in academic and public buildings on the campus. An internal energy policy, awareness creation and establishment of an energy management unit in the University system are some of the measures that can guarantee good savings. This paper estimates electricity savings potentials of 10-20% in Nigerian higher institutions through well articulated and vigorously pursued energy efficiency programmes in the system.
