ABSTRACT
Sustainable energy management essentially plays a critical role in the socio economic activities of man and in the overall productive processes of a nation. Consequently, efficient energy utilization and robust management are key parameters that drive energy sustainability. Energy efficiency in this context can be viewed as a function of technological advancement, owing to the fact that what are regarded as efficient products in the 1970’s and thereafter, have in contemporary time been replaced by the modern efficient ones. In the industries, obsolete equipment are giving way to more efficient and automated ones. Architects too have improved considerably in the design of energy efficient buildings, while in the transport sector, energy efficient automobiles that are eco -friendly are gradually emerging.
