What is considered "individual energy end use"?

A typical energy end uses are lighting, heating, cooling, fans, pumps, service hot water, etc. In a manufacturing facility you would still have these end uses but you also have industrial process. This could be broken down several ways and there is probably no right way to do it. Following the logic about you could maybe breakdown the manufacturing process into conveyance, fans, heating, etc. depending on the process. I would not considered Widget A an end use if the process to make it is comprised of different types of energy using equipment. If it is all just motors however maybe that makes sense. I think you have to consider the specific process to make this determination. Part of that would be how the process energy use would be metered. Obviously this gets potentially messy in a manufacturing facility.
