Global Energy Flows
http://www.glbrc.org/education-and-outreach/teachers-13

Great Lakes Bioenergy Research Center, U.S. Department of Energy

In this activity, students analyze data detailing global energy sources and sinks (uses) and construct a diagram to show the relative scale and the connections between them. Discussions of scale; historical, socio-environmental, and geographic variation in this data; and implications for future energy use are included.

Activity takes one to two 50-minute class periods.

Benchmarks for Science Literacy
Learn more about the Benchmarks

Industry, transportation, urban development, agriculture, and most other human activities are closely tied to the amount and kind of energy available. People in different parts of the world have different amounts and kinds of energy resources to use and use them for different purposes.

Teaching Tips

  • Educators will need significant preparation time to facilitate this lesson.
  • Educators may wish to have students use more recent energy data from the International Energy Agency.
  • The resource material can be used for different types of exercises on regional/national/global levels. Students could be broken into different groups (regions) and share their pie charts and Sankey Diagrams and discuss what kind of policies might be needed to have sustainable energy development.

About the Science

  • All data in this activity comes from the United Nations 4th Inter-governmental Panel on Climate Change (IPCC) published in 2007. Students may wish to use more recent data that reflects recent downturns in economic activity.
  • Comments from expert scientist: This activity set is well-written, easy to understand, addresses a very important topic for increasing energy literacy. The materials assume an instructor and/or student inherently understands the definition of "source" and "sink." Discussion questions are interesting and answers are provided. The use of real energy flow diagrams and data is excellent.

About the Pedagogy

  • The resource contains excellent step-by-step instructions for teachers and support materials for the students.
  • Students will require prior knowledge about renewable and non-renewable energy sources, basic physics concepts related to the transformation of energy and matter, and the joule (J) as a unit of energy.

Technical Details/Ease of Use

  • The high-quality Global Energy Flows package include Teacher Instructions and Answer Key, Student Pages, Global Energy Flow Graph Slide Set, IPCC Chapter 4, Energy Consumption by Source Raw Data.
