Sankey diagram
National energy flow
Generation by source, split into consumption and losses.
What this chart shows
The classic Sankey use case: every terawatt-hour generated is either consumed by a sector or lost in transmission. Losses get their own band, so efficiency is a width you can measure with your eyes.
