The Electricity Use at Home activity develops students’ auditing skills and raises awareness around energy consumption at home. The exercise enables students to learn where electricity is used at home, investigate how much is used and the frequency of use over time. Students are then able to readily identify where electricity use is highest and develop recommendations for energy saving opportunities.

Energy Use, Electricity, Conversions

1. Students will be able to identify where electricity is used at home
2. Students will be able to calculate electricity use of various appliances over time
3. Students will be able to order where electricity use is highest and develop recommendations for energy saving opportunities

3. Compare your data with someone else from your class.
a) How did your electricity use compare to your classmate’s? What was similar or different?
b) What external factors (such as building size, material, number of inhabitants, etc.) may affect electricity consumption between your two homes?
c) What other behavioural factors affect electric energy consumption in the home?
