In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy. Learners use a meter to measure the energy use of household appliances and calculate and extrapolate data. Use this activity for any lesson on climate change, energy consumption, and CO2 emissions. Note: the cost of materials includes the cost of one Kill-a-Watt meter.
