A comparison was made of energy conservation data for the years 1974 and 1972 to determine the degree to which conservation was being accomplished by the cement industry. It was found that the cement industry reduced its total consumption of petroleum products by 10.7% in 1974 as compared to 1972. Natural gas consumption declined 7.2% in the same period. The reduction in natural gas and oil consumption was offset by a 13.8% increase in coal usage. The industry's total energy usage declined 0.7% while production expanded 0.9%. Electric power consumption increased 2.6% in 1974 compared to the base year 1972, although production increased less than 1%. This increase in power usage reflects the industry-wide adoption of EPA air pollution control standards. The cement industry continued its trend towards greater kiln fuel flexibility with the number of plants using more than one type of kiln fuel increasing 16%. Wet-process plants reduced their unit energy requirement 0.2% while the unit energy consumption for dry-process plants declined 2.6%. Only 17% of the plants surveyed used over 9.0 million Btus per ton in 1974 compared to 21% in 1972.
