This set of flow charts illustrates energy sources and uses in 136 countries around the world. The data from 2007, but is still useful for comparing energy patterns in different countries. This is the first comprehensive package of worldwide, country-level energy flowcharts that has been produced.

Teaching Tips

  • Teachers will need to come up with their own strategies to make use of this tool by either creating a lesson around it or incorporating it 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" 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 in 2007 the Russian Federation and Saudi Arabia were the largest exporters of oil; France relied heavily on nuclear power for generating electricity; Costa Rica was rich in geothermal energy; and New Zealand had a mix of renewable energy (geothermal, hydro and wind) as part of its portfolio.
  • Since 2007, countries such as China, Brazil, and India have had significant changes in thier energy portfolios.
  • This type of graphic is called a Sankey diagram.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • This resource compiles the energy flow data from IEA into a scrollable, user-friendly document that provides visual analysis of our global energy resources.
  • There is no page or country finder, but the maps are in alphabetical order by nation.
  • Teachers will need to find ways to scaffold this information or use small parts of it. For example, the data could be used in case studies or to answer investigative questions.
