U.S. Oil Import Sankey Movie

Renown Rocky Mountain Institute (RMI) founded in 1982 by Lovins and Lovins have an interactive oil imports map on their MOVE project webpage.

You can see the oil imports to the United States from January 1973 to August 2008 on a map that depicts the flow quantities as Sankey arrows linking the country of origin and the U.S. If you switch to the unit “Dollar”, you can see the value of the oil imported depicted as Sankey arrows.

One can play the the whole 35-year period as a movie, or use the slider on the time line to see individual months. The data used is from publicy accessible EIA/DOE statistics.

The United States is still 60 % dependent on imported oil. MRI’s MOVE project seeks possibilities to reduce foreign crude oil dependencies. The goal is to “get completely off oil by 2050, led by business for profit.”

Go to the RMI movie page and try it yourself. When I did the Lybia Oil Export map last year I wasn’t aware of this Sankey movie, which is of course much nicer.

Oil Exports visualized as Sankey Diagram

After my posts on visualizing Rotterdam port’s imports/exports and on Internet traffic maps, I have started to experiment with showing the export quantities and destinations for a certain trade good.

I wanted to do a Saudia-Arabia or Irak oil export Sankey map, but couldn’t find good data. I finally came across this summary on Lybian oil exports, and converted the data from the pie chart Lybian Oil Exports, by Destination, 2006 to a Sankey style export flow diagram.

It was new to me that “Libya has the largest proven oil reserves in Africa” with 41.5 billion barrels, and estimated net exports of 1.525 million barrels per day in 2006.

The underlying map is a crop from a World map found on Wikicommons. I think it could be a little more transparent though…
