Under the patronage of HRH Prince Abdulaziz Ibn Salman, a ?mandatory energy efficiency programme? was developed to encourage the cement industry to reduce its use of fossil fuels and overall energy consumption. Currently, heavy fuel oil is supplied to the cement industry throughout the Kingdom at around US$35/t. Currently, one third of its overall energy production is consumed in the Kingdom, and it is estimated that by 2020 around 60% of overall energy production will be required to fulfill the local demand.
