Denmark Energy Flows

Denmark’s Energy Flows for the year 2016 were published by Danish Energy Agency (‘Energistyrelsen’).

For detail, I recommend to study the high-quality image of the Sankey diagam in this PDF.

Flows are in petajoule (PJ). Smaller flows are shown with a minimum width, so they are not to scale with the others, but remain visible. Even zero flows are shown, either because there is actually a quantity (less than 1 PJ) that is just rounded, or, because in other years there might be a flow quantity available for them. Arrows arrive at the nodes separately, their flow labels shown inside the node. This feature enhances legibility quite a bit.
