OICC Press International Journal of Energy and Environmental Engineering 2251-6832 3 1 (December 2012) 2012 07 11 Efficient energy utilization as a tool for sustainable development in Nigeria 10.1186/2251-6832-3-11 EN Sunday Olayinka Oyedepo Mechanical Engineering Department, Covenant University, Ota, 2023, NG Journal Article 2012 07 11 Abstract This study takes a look at the national energy outlook of Nigeria. Energy utilization pattern of the country was investigated, and possible areas of energy conservation in the major economic sectors (industry, transportation, office and residential buildings) were considered. The study reveals that there is inefficient utilization of energy in the major economic sectors of the country. This study presented several energy conservation opportunities to cause energy savings and identified about six major areas through which energy conservation measures can effectively cause some savings in energy and allow for its stability. Such areas of focus for application of energy conservation measures include manufacturing/industrial setup, office and residential buildings, power generation and distribution, transportation, energy conservation through waste control etc. Various measures that need to be considered and appropriately addressed in moving towards energy sustainability in Nigeria have been recommended among which are energy use in ventilating equipment, lighting, electrically operated industrial machines and engines, design for energy-efficient buildings etc.
