- Excellent springboard to discussing a variety of energy topics.
- This can help set the stage for another National Academies online visualization on Energy Efficiency: http://needtoknow.nas.edu/energy/interactive/understanding-efficiency/
About the Science
- This interactive diagram is based on the energy flow diagram produced by Lawrence Livermore National Laboratory in 2009. The data are from the Energy Information Administration of the U.S. Department of Energy (DOE/EIA-0384(2008), June 2009).
- This is a Sankey diagram. Schmidt, M., 2008, Journal of Industrial Ecology, vol. 12, no. 1, pp. 82-94. See also http://www.sankey-diagrams.com for more information.
- Passed initial science review - expert science review pending.
About the Pedagogy
- Excellent tool to show the sources of energy consumed in the U.S. and what happens along the way between energy production and consumption.
- The questions that must be emphasized are: 1) what is "unused" energy? 2) why does it account for nearly 60 percent of our overall energy use? and 3) why is energy conservation and efficiency so crucial?
