Found the below two videos while browsing for the keyword “sankey diagrams” on youtube.com.

This seems to be the output of a student assignment at Universidad Nacional de Colombia. Note that the narrative is in Spanish.

In the first video Marcela Rojas explains the basics of building up Sankey diagrams and how to create a national energy balance diagram.

In the other, longer video Paola Cifuentes shows us how she created the ‘balanco energetico minero de Colombia’.

Enjoy!
