Introduction to Energy Efficiency – Energy Efficiency and Trade-Offs – Student

Summary

Students test two paper fan designs to experience efficiency as smarter design, then compare real appliance kWh data to identify more and less efficient options. A budget-constrained home design challenge asks them to weigh upfront costs, annual energy use, and comfort across two differentiated options. Pairs directly with the companion teacher guide and works well for middle or high school energy efficiency units.
