Sankey diagrams

1/1

The thickness of the arrow represents the amount of energy.

Sankey diagrams are just energy transformation diagrams – they make it easy to see at a glance how much of the input energy is being usefully employed compared to how much is being wasted.

The thicker the arrow, the more energy it represents – so you see a big thick arrow going in, then several smaller arrows going off to show the different energy transformations taking place.
