As the government considers a revamp of electricity tariffs, we took a look at Hong Kong's power consumption. Who uses all the electricity in our city and what is it used on? This graphic was printed last week as a full broadsheet back page. 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).
