Simon Scarr has won a SOPA 2013 Award for Excellence in Information Graphics (PDF, see p. 13) with this Sankey diagram titled ‘Wiring the City’ originally created for the South China Morning post.

It shows energy flows and energy use in Hong Kong

On his blog he writes: “… we took a look at Hong Kong’s power consumption. Who uses all the electricity in our city and what is it used on? (…) Data set was provided by the government’s Electrical and Mechanical Services Department. (…) This type of chart is known as a Sankey diagram. The thickness of each line reflects a value. In this case, an amount of electricity in terajoules. All of the lines add up to give subtotals and totals by users (grey) and end use (coloured).”

Congratulations, Simon!
