Abstract 

The main aim of this research is to determine how energy improvement, efficiency and conservation can be achieved in industry such as the cement plant. Energy, is an essential ingredient for socio-economic development and economic growth. The objective of the energy system is to provide energy services. Energy services are the desired and useful products, processes or indeed services that result from the use of energy, such as for lighting, provision of air-conditioned indoor climate, refrigerated storage, transportation, appropriate temperatures for cooking, industrial processes such as conversion of raw materials to final products, etc. The energy chain to deliver these cited services begins with the collection or extraction of primary energy, which is then converted into energy carriers suitable for various end-uses. These energy carriers are used in energy end-use technologies to provide the desired energy services

It is a well-known fact that Energy is one of the most important catalysts in wealth generation, economic growth, and social development in all countries. In industry particularly in cement plants, the energy cost forms about 35 to 45% of the total cost of production. Out of this, thermal energy constitutes around 70%, whereas electrical energy about 30%, which may vary from plant to plant and local conditions. Energy cost is a major factor in pricing of a product and thus the energy cost needs to be minimized to the extent possible to ensure profitable operations and to reduce the deficit in the energy sector. The energy input to the cement plant includes both thermal and electrical energy and cost of these two forms of energy needs to be controlled.
