Tom Van Heeswijk and Changsoon Choi, landscape architecture master students at Wageningen University in the Netherlands have created the below “preliminary Sankey diagram of the Amsterdam energy system”. This is part of the larger project URBAN PULSE described on the research page of the NRG lab website.
Only the top part of a larger Sankey diagram is seen here, the bottom part with fossil fuels apparently cropped. No units or figures shown, so just a schematic visualization.
Nevertheless some interesting features: in contrast to many other Sankey diagrams, nodes are not depicted with outlines but shown as gaps with their name. Electricity is highlighted as red bands while all other flows have a single-hatching fill pattern.
Beauty of simplicity…
