Estimated International Energy Flows 2007

Clara Smith, Lawrence Livermore National Laboratory

This Energy Flow Charts website is a set of energy Sankey diagrams or flow charts for 136 countries constructed from data maintained by the International Energy Agency (IEA) and reflects the energy use patterns for 2007.

Teaching Tips

  • Teachers must come up with their own strategies to make use of this tool by either creating a lesson around this information or carefully inserting this tool into a unit.
  • While these diagrams may be initially difficult for some learners to grasp, a careful initial walk through followed by "pair and share" can help make the basic "spaghetti diagram" logic easier to understand.
  • These flow charts can be used in an energy unit with a well-crafted inquiry and discovery project that guides students through a global "compare and contrast" worksheet/exercise where they can construct their own conclusions.
  • Educators will want to discuss impact of population, geography, and seasonal variability on the magnitude and timing of energy use.

About the Science

  • The diagrams show domestic and imported energy for each country.
  • These flow charts provide overviews of energy input and outputs, allowing users to examine the diverse energy portfolios of different nations.
  • For example, these diagrams show that the Russian Federation and Saudi Arabia are largest exporters of oil; France relies heavily on nuclear power for generating electricity; Costa Rica is rich in Geothermal; and New Zealand has a mix of renewable energy (Geothermal, Hydro and Wind) as part of its portfolio.
  • Because the development and vetting of these flow charts takes several years, the data are from 2007. Since then, countries such as China, Brazil, and India have had significant energy portfolio changes.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • Except for the fact there is no page or country finder (maps are in alphabetical order by nation) this resource compiles the energy flow data from IEA into a scrollable, user-friendly document that provides visual analysis of our global energy resources.
  • Provides a visual representation to frame the sources and use of energy by nations around the world.
  • Teachers will need to find ways to scaffold this information.

Disciplinary Core Ideas: 4

HS-PS3.A1:Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system’s total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms.

HS-PS3.A2:At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy.
