Question

Can you guys give me the calculation for a Sankey diagram of led light, filament lamp and thermal power station by seeing the picture?
(Plz do not write anything unrelated)

Answer 1

Explanation:

Note: In the original publication the Sankey diagrams are not to scale to each other, so that the arrows for the primary energy values (320 units in the first, 224 units in the second, and 64 units in the third one) on the left all show the same magnitude. By bringing all three flow diagrams to the same scale, the significant difference between them becomes even more visible.
