Introduction to Energy Efficiency – Bell Ringer
Summary
Three short bell ringer prompts introduce students to energy efficiency by connecting the concept to everyday decisions and personal behavior. Each prompt builds slightly in complexity from personal examples, to behavioral trade-offs, to the nuanced relationship between efficiency and waste. Works well as a standalone warmup or as an opening hook for a middle or high school energy efficiency unit.
Energy efficiency means using less energy to do the same work. What is one example from your own life where something uses less energy but works just as well?

List three ways you could use less energy in one day without changing your lifestyle or giving anything up. Do you think these choices would help the planet? Why or why not?

Can something be energy efficient but still wasteful? Give an example, or explain why not.
