The article ‘The Use of Energy in Malaysia: Tracing Energy Flows from Primary Source to End Use’ by Chinhao Chong, Weidou Ni, Linwei Ma, Pei Liu and Zheng Li features the two Sankey diagrams below. The article is available open access in Energies 2015, 8(4), pp. 2828-2866.

The first diagram is an ‘Energy Allocation Diagram’ that is structured (from left to right) in columns, fuel, primary energy supply (energy generation), primary energy supply (energy conversion), consumption/use in different sectors. The consuming sectors (transport, commercial, residential, etc.) are further broken down into groups, offering one more level of detail. Flows are in million tonnes of oil equivalents (Mtoe), data is for 2011.

The other Sankey diagrma offers a detailed view of oil and oil products. Flows are also shown in Mtoe, data again for 2011. The upper half is domestic production, the bottom part shows imports. ‘ATF’ could be automobile transmission fuel (machine oil), not sure about ‘AV’. Losses and stock changes branch out vertically to the top.

A nice, really well-structured diagram. Clear and comprehensible.
