The cement industrys total energy demand increased by 9.3 percent. Clinker production, however, rose by 26 percent. Therefore, energy use per tonne of clinker decreased by 14 percent over the nine-year period. These energy efficiency gains reflect continued technology improve- The cement sub-sector consumes approximately 1215% of total industrial energy use. Therefore, a state of art review on the energy use and savings is necessary to identify energy wastage so that necessary measures could be implemented to reduce energy consumption in this sub-sector.

Jun 02, 2021 The concrete and paper industries burn large amounts of coal to produce heat. The steel industry uses coal indirectly as coal coke to smelt iron ore into iron to make steel. The high temperatures created by burning coal coke give steel the strength and flexibility needed for bridges, buildings, and automobiles. Energy consumption by the cement industry is estimated at about 2% of the global primary energy consumption, or almost 5% of the total global industrial energy consumption . Because of the dominant use of carbon-intensive fuels, such as coal in clinker making, the cement industry is a major source of CO 2 emissions.

Energy Use. A cement manufacturing plant requires significant amounts of energy to produce clinker, the main ingredient in cement. Energy in the form of electricity is required to prepare the raw meal (typically limestone, clay, sand and iron ore), run the kiln and, in integrated cement plants, to grind the clinker, gypsum and other materials to produce cement in grinding mills. Chapter 3.3.4 describes the main drivers for energy consumption in the cement industry. The main driver is the production process of clinker. About 96% of the total energy consumption is used for producing clinker in the kilns. The main fuels used for clinker production are Mazout and natural gas. A much smaller part of the total
