Energy Footprints

DOE developed a series of Energy Footprints to map the flow of energy supply and demand in U.S. manufacturing industries. Identifying the sources and end uses of energy helps to pinpoint areas of energy intensity and characterize the unique energy needs of individual industries.

On the supply side, the footprints provide details on the energy purchased from utilities (electricity, fossil fuels), energy generated onsite, and excess energy transported to the local grid. On the demand side, the footprints illustrate where and how energy is used within a typical plant, from central boilers to motors. Most important, the footprints identify where energy is lost due to inefficiencies, both inside and outside the plant boundary. Considerable energy is lost, for example, in steam and power generation systems, as well as in the pipe and transmission lines that carry energy to processes. Losses are critical, as they represent immediate opportunities to improve efficiency and lower energy consumption through implementation of best energy management practices, improved energy systems, and new technology.

The Energy Footprints are based on the 1998 Manufacturing Energy Consumption Survey (MECS) conducted by the U.S. DOE Energy Information Administration. Distributions for motor-driven systems are taken from the U.S. Industrial Motor Systems Market Opportunities Assessment (1998, ORNL/Xenergy, for the DOE/EERE). The data in these sources spans entire industries, and thus represents an average picture of energy use. Actual energy patterns in individual plants will vary according to site.
