    Manufacturing of cement is identified as one of the most energy intensive industries in the world. Therefore, there is a need for its effective and efficient utilization and hence conservation. In order to produce clinker, rotary kilns are widely used in cement plants. This study takes a look at the energy source, utilization and conservation in a Cement Company in Nigeria. The company’s energy source was determined, utilization pattern investigated and possible areas of energy conservation considered. The rotary kiln of this plant where the large form of energy is consumed has a capacity of 6000 tonnes per day. It was found that about 20% of the total input energy was being lost through hot flue gas (5.09%), cooler stack (12.4%) and kiln shell (2.61% convection and radiation). To recover some of this heat energy loses, a feasible energy management method was introduced and discussed. Findings showed that approximately 4MW of electrical power could be recovered through conservation and proper energy management.
