    • Manufacturing Thermal Energy Use in 2014

    Metadata Updated: July 24, 2025

    The first data set estimates thermal energy use (i.e., fuels combusted for process heating, boilers, and combined heat and power/cogeneration) by end use, temperature, county, and facility employment size class for all U.S. manufacturing industries in 2014. The estimation methodology builds off of prior estimates of industrial energy use (https://dx.doi.org/10.7799/1481899, https://dx.doi.org/10.7799/1461488). The second data set estimates hourly heat load (as a fraction of annual energy used for heat) using hourly observations of industrial boiler and combined heat and power/cogeneration heat load from EPA's Air Markets Program Data, weekly operating hours in 2014 from Census Quarterly Survey of Plant Capacity Utilization, and annual production hours reported by assessments conducted by Industrial Assessment Centers. ERRATA: Representative heat load shapes were revised based on an updated estimation methodology. Hourly heat load relative to peak load is estimated by NAICS code, employment size class, month, day of week (Monday == 0) for a range of average weekly operating hours for boilers and process heating. The high and low operating hours values represent the 95% confidence interval of average weekly operating hours.
