Visualizing Alberta energy flow, emissions and water use by sector

Related to my earlier post Visualizing Canadian Energy Flows with d3.js Sankey diagrams, here I am presenting Sankey diagrams with data from the publication:

2011. Development of Energy, Emission and Water Flow Sankey Diagrams for the Province of Alberta Through Modeling Final Report. April 11, 2011. Amit Kumar, Veena Subramanyam, Md Ruhul Kabir. Department of Mechanical Engineering, University of Alberta.
Sankey diagrams (click on links for interactive diagrams):
 The last is particularly illuminating, showing a huge amount of both surface water and ground water used by the petroleum industry from the Athabasca River basin. See http://en.wikipedia.org/wiki/Athabasca_oil_sands#Water:

Thanks again to Mike Bostock and his d3.js plugin for making Sankey diagrams

Visualizing Canadian Energy Flows with d3.js Sankey diagrams

I have been working with processing.js but wanted to learn a little about d3js for visualizations, so took a look at Mike Bostock's d3.js plugin for making Sankey diagrams.

So I pulled down two documents that had energy flow diagrams for Canada:

I extracted the data from these diagrams and built these interactive Sankey energy flows:
Note that these two documents are looking at slightly different views of energy flows (and 2007 does not include Uranium), so can't be compared directly.

If you have any (preferably Canadian) datasets that could be presented in this fashion, let me know and we can collaborate in getting them into this form.

Addendum: 2012 10 26 22:28: Wow! The Economist's blog Graphic detail: Charts, maps and infographics has an article about this post: Charting Canada's energy: Go with the flow
