## P007

### Home Appliances

Q316 Appliances in home ...

• Said that he didn't know whether some of his appliances were electric or gas
• Understood what a hot water heater was

#### Electricity Use Questions

• Didn't know either questions (\$ or kWh)

### Pre-test

#### 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
• Asked whether the washing machine was a high efficiency one because the one he has at home was energy efficient
• 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

#### Electricity Cost / Electricity Use

• Believed that when people are using less, the cost will be lower for the utility
• Wasn't sure whether the question only applied to households
• Wasn't sure how it would rank differently
• Didn't seem to get the concept that cost for the utility is dependent on both residential and commercial demand

#### Electricity Definitions

Q321 Units of electrical energy called

• Didn't know

Q828 Power rating

• Thought that each appliance hod a power rating for how much it used for a given amount of time
• Thinks it has to do with multiplication but he doesn't know

#### Cost of a kWh

Q257 Avrg Cost

• Complete guess

#### Ranking Energy Saving Actions

Q824 Rank actions

• Believed that proactive saving actions save more energy (i.e. reducing temperature on water heater, turning up the temperature on the AC, etc)
• Was concerned about whether the washing machine was efficient or not
• Used his own usage patterns to rank the actions but wasn't sure whether it was supposed to be his own actions or for the average household
• Average household usage not clear to him
• Wanted to know what consisted of the US household (i.e. 4 householders)
• Wanted to know how often does the US household uses the dryer (every week? every month?)

#### Simulation Introduction

• Was shown the Smith's introduction
• Was anchored on the three appliances that were shown in the picture
• Understood that it was a mid-sized home
• Understood their budget was \$150

#### Passive Learning

• Said that most of the rankings he made were pretty much on target
• Didn't know that a refrigerator was that different in usage compared to a freezer
• Wasn't very vocal when thinking aloud
• He was just trying to memorize the ranking
• Said his guess for the Electricity Cost / Use question was pretty much the same

### Post-Test

Q269 Electricity Use Questions
