How effectively is energy used in U.S. manufacturing? How much greenhouse gas (GHG) is emitted from combustion in manufacturing operations? The U.S. Manufacturing Energy Use and Greenhouse Gas Emissions Analysis from the Oak Ridge National Laboratory traces energy from supply (fuel, electricity, and steam) to major end-use applications in U.S. manufacturing. The report ranks the energy use, energy losses, and energy-related greenhouse gas (GHG) emissions of 15 sectors. These sectors collectively account for 94% of all energy use in manufacturing. In addition, in-depth profiles of energy flows are available for U.S. manufacturing as a whole and for the five largest energy-consuming sectors:

  • Chemicals
  • Forest products
  • Petroleum refining
  • Food and beverages
  • Iron and steel

The report references the Manufacturing Energy and Carbon Footprints, which are based on data from the U.S. Energy Information Administration's Manufacturing Energy Consumption Survey. This analysis can help assess the potential impacts of energy-efficiency improvements at the macro level.
