Energy Analysis by Sector

Manufacturers often rely on energy-intensive technologies and processes. AMO conducts a range of analyses to explore energy use and trends by sector.

MANUFACTURING ENERGY and carbon footprints 

Manufacturing Energy and Carbon Footprints map the flow of energy supply, demand, and losses as well as greenhouse gas combustion emissions in diverse U.S. manufacturing industries, based on 2010 EIA MECS data. Detailed analysis of the 2006 footprints is available in the U.S. Manufacturing Energy Use and Greenhouse Gas Emissions Analysis report published November 2012.



Static Manufacturing Energy Sankey Diagrams

Static Manufacturing Energy Sankey Diagrams map energy supply, demand, and losses in the U.S. Manufacturing sector using data from the AMO Manufacturing Energy and Carbon Footprints.  The Sankey diagrams visually complement the Footprints by presenting weighted energy flow lines, capturing the pathways from energy source to facility end use in succinct images, and displaying the amount of energy applied directly to an end use and the energy losses. The Sankey Diagrams and the footprints both rely on energy use data from the 2010 EIA Manufacturing Energy Consumption Survey.

Dynamic Manufacturing energy Sankey Tool

AMO’s interactive Dynamic Manufacturing Energy Sankey Tool displays the Manufacturing Energy Footprint data as dynamic Sankey diagrams. Line widths indicate the volume of energy that flows to major energy end uses in manufacturing and line colors indicate fuel, steam, electricity, and applied or lost energy. Users can pan, zoom, and customize the display to explore the flow of energy use at the macro scale or compare energy consumption across manufacturing subsectors. Selected images can be saved for export.

Energy & Environmental Profiles

Energy & Environmental Profiles describe selected U.S. industries in terms of their energy and material consumption, market trends, and environmental performance. These detailed reports benchmark the energy and environmental characteristics of the key technologies that are used in the major processes of each selected industry.

Bandwidth Studies

Starting in 2013, AMO developed and refined a consistent methodology for bandwidth studies such that comparisons could be made across the manufacturing sector.  Energy Bandwidth Studies analyze energy use and the potential for energy savings in various processes for selected manufacturing sectors. The studies estimate potential energy savings by calculating differences among the typical energy consumption levels for a specific process and lower consumption levels based on the use of state of the art technology and technology currently under research and development. Bandwidth studies are available for the following sectors, and additional studies are underway:

Earlier energy bandwidth studies are available for the following sectors. Methodologies used in these earlier studies vary.


Energy consumption among manufacturing facilities is heavily weighted toward larger, more energy-intensive companies. A study estimates the number of manufacturing large energy users (LEUs) in every state by manufacturing sector. Large energy users are defined as manufacturing facilities with total site energy consumption greater than 0.2 TBtu.
