Blog reader Johan Land submitted the Sankey diagram below. “As I am interested in the energy field I especially was fascinated by the LLNL graph over US energy consumption. I spent the weekend on further enhancing the LLNL graph using a trial version of e!Sankey (and data that I have gathered the last few years). I’m attaching the PNG-file for this graph. Feel free to share it if you like the graph!”

The typical LLNL graph has been extended by the red section on the left that shows a world energy breakdown. Only the U.S. energy consumption is traced further.
The second extension is the pink section. Here, Johan has broken down the energy use sectors ‘Residential’, ‘Commercial’, ‘Industrial’ and ‘Transportation’ in one or two further steps.

All flows are in TWh, data is from 2005 to 2009. The author used several additional data sources and recompiled the data, so that “figures may differ from Lawrence Livermore Laboratory estimations”. See notes for further information.

Good Sankey diagram, and definitely a great job Johan did here. The only suggestion I have, is to add percentage figures to the regional energy breakdown (red section on the left). Unfortunately, the watermark spoils the overall impression, but this is owed to the fact that he used a free trial version.

Johan also mentioned that he is working on forecasts up to 2050, and an animated GIF “running it over time since 1950 up until 2008”. Hope to be able to show you these here on the blog someday.

    why is there no solar flow to residential, commercial and industrial sites.
