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
  • Surprised by dryer and washer
    • He was just trying to memorize the ranking
    • Said his guess for the Electricity Cost / Use question was pretty much the same

Post-Test

Q296 Electricity Knowledge Questions

  • Was anchored to the four appliances that were shown in the images for the Smith's Family
    • When asked why he only used those 3 appliances, he said that he thought those were the appliances that made up the budget
  • Reiterated energy saving actions

Evaluation Phase

  • Should people who get the passive learning condition still see the evaluation phase sections?
  • Thought that 20% reduction was "reasonable" because his family was not "egregious" on usage as is
    • This plays into the unrealistic reduction forecasts made by people
    • Self-set goals might lead to a lot of unrealistic expectations

Demographics

  • Was questioning how the self-efficacy questions pertained to first part of the survey

Hypothesis: Electricity hyoptheticals were meant to instill a sense of one's impact and usage of resources
