Content/concepts goals for this activity

  • Analyze energy source, usage, and cost by region of US
  • Compare household energy use to regional norms
  • Calculate household CO2 emissions based on electricity source
  • Discuss ways to reduce electrical footprint

Higher order thinking skills goals for this activity

  • Interpretation of tabular and graphical data
  • Ability to analyze energy use patterns

Other skills goals for this activity

  • Communication via writing and oral presentation

Description of the activity/assignment

Students use their household electric bills and available online data sets describing US regional electricity use, cost, and source to explore household energy use on personal, regional and national scales.

Determining whether students have met the goals

Students will create bar charts to summarize the regional data, participate in a discussion of how their electric bills compare to the regional average and the possible reasons for variation, and calculate their CO2 emissions and write about how to reduce their electric use.
