Sankey Diagrams

Kris commented on my last post, that there is an updated version of the Sankey diagram on energy flows in Austria in 2006 to be found in the Statistical Yearbook Austria 2009 on page 360 (page 6 in this PDF).

I also checked out some other Austrian sites and found one for Austrian Energy Flows 2005 (Energieflussbild Österreich 2005) on the Austrian Energy Agency website. It is a little more colorful, and has more information too.

Flows are in TJ. The diagram is divided into four sections, namely “Aufkommen” (energence?), “Umwandlung” (transformation), “Sonst. Verwendung und Verluste” (other uses and losses), and “Endenergieeinsatz” (final energy use). The color code for the energy types is as follows: oil (pale orange), electric energy (red), coal (dark grey), gas (yellow), renewables (dark green), distance heating (light green), hydro (blue). On the right side useful energy is shown in purple, and losses are displayed as light grey arrows. (Thank you to my friend Leo for the translations…).

Yet another national energy flow Sankey diagram, and indeed a very beautiful one. Hope to see updates of it every year.

Found this Sankey diagram displaying the energy flows in Austria in 2002 on a web page with didactic material from that country.

Unfortunately this copy of the diagram isn’t very large, and I have trouble reading and translating everything. Flows are in petajoule (PJ), source given is Statistics Austria.

On the left are imports, withdrawl from stocks, and domestic production. Losses branch off in black to the top. The diagram differs fundamentally from the ones I have presented for other coutries (such as for New Zealand, the United Kingdom, or the U.S.) in two ways:
First, it doesn’t show the energy use by sectors, but instead a breakdown by energetic end use (985 PJ), non-energetic end use (101 PJ), exports (150 PJ), stock increase (18 PJ), as well as energy use within the energy sector itself (81 PJ).
Second, the colors of the flows are used to differentiate between liquid fossil (dark blue), gaseous fossil (medium grey) and solid fossils (light bluegrey) rather than specific energy carriers. Furthermore biogenic energy flows are shown in medium blue, renewables in very light blue. Converted electric energy is in dark grey.
