B4E: Energy loss is synonym of ‘non-quality’

French La Courneuve based engineering consultancy B4E shows the following Sankey diagram on their energy diagnostics page.

Unfortunately the resolution is not good enough to determine any detail. I can understand as much as that they present fuels (“combustibles”) and electric energy (“electricit√©”) as the main energy sources. From these two sources the use of energy and losses (“pertes”) in a company is visualized in a bottom-to-top layout. No numbers are given, so this is just a schematic visualization.

As they say in the text: energy loss is synonym of ‘non-quality’
