Energy Consumption Benchmark Guide: Cement Clinker Production
The Energy Use Plant Ranking (bar chart) helps cement plants compare their own energy use to that of other plants in the industry. Along the X axis, the chart ranks individual plants from the most efficient (1) to the least efficient (15) in terms of the number of gigajoules used per tonnes of clinker (GJ/T), ranging in single digit increments from 0 to 8 along the Y axis.

The cement industry is the most energy intensive of all manufacturing
Energy-intensive manufacturing accounted for a little more than half of total industrial energy use. Although the cement industry used only one-quarter of one percent of total U.S. energy, it is the most energy-intensive of all manufacturing industries, with a share of national energy use roughly 10 times its share of the nation''s gross output of goods and services .

Fossil fuels continue to provide the majority of energy in the cement sector, with alternative fuels such as biomass and waste accounting for very small portions. Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker
