A 2002 Integrated Pollution Prevention and Control (IPPC) report on energy efficiency by UK’s Environment Agency features the following Sankey diagram on page 10.

It shows energy flows in a paper mill. Unfortuntately no values are given nor a unit. So this is to be considered merely as a schematic diagram, not necessarily based on real energy data.

The guidance document explains (p.9):

“It is useful to supplement energy consumption information with energy balances (e.g. “Sankey” diagrams, other flow diagrams or descriptions) to illustrate how energy is used throughout the process (see Figure 2.1). This is particularly relevant where energy conversion is highly integrated within the activities, in order to illustrate any inter-dependencies between energy use and selection of other operational or environmental control measures.”
