Illustration of an energy footprint of the U.S. Manufacturing Sector Total Energy Input for Heat and Power: 24658 Trillion Btu. This diagram shows how Fossil Energy Supply and a Utility Power Plant creates Energy Supply, then travels within the Plant Boundary into Central Energy Generation/Utilities, then Energy Distribution, then Energy Consumption, and finally Process Energy Use, all the while recycling energy and have energy losses.
