In the Net Zero Scenario the thermal energy intensity of clinker production declines by slightly less than 1% per year to a global average of around 3.3 GJ/t, and the electricity intensity of cement production as a whole fall to less than 95 kWh/t (relative to about 105 Reducing energy consumption of a raw mill in cement ,Cement production in the world is currently about 1.6 billion ton per year. About 2% of the electricity produced in the whole world is used during the grinding Reducing energy consumption of a raw mill in cement ,While total electrical energy consumption for cement production is about 100 kWh/ton of cement, roughly two thirds are used for particle size reduction [2].
