Ranking Appliances
Q253 Rank the ten appliances below ...
- Got energy usage probes correct
- Utilized a ranking method by comparing appliances to a light bulb
- Stated that the electric oven at 450 degrees makes the kitchen hot in 10 min, so it must use more than a light bulb

- Believed that it still used more than a light bulb
- Noticed his bill gets higher the more laundry he does
- Thinks the increase in usage is attributed to the washing machine and not dryer
- Believed that fridge and freezer were essentially the same in usage
