Infrastructure is coming with the smart grid, technology is developed and being fine tuned via multiple presentation mediums AND culturally, we’re already there. Feedback is everywhere, calorie count of food, cotton counts on clothing.

2. Underlying Assumptions
1. Technology & new media are changing how people
interact with our natural, built, and social worlds.

3. Underlying Assumptions
1. Technology & new media are changing how people
interact with our natural, built, and social worlds.
2. There are potential opportunities to leverage these
changes for pro-social / pro-environmental benefit.

4. Underlying Assumptions
1. Technology & new media are changing how people
interact with our natural, built, and social worlds.
2. There are potential opportunities to leverage these
changes for pro-social / pro-environmental benefit.
3. Psychology provides a rich history and theoretical base
with which to understand this potential.

6. What is Feedback?
“Information about the result of a process
or action that can be used in modification
or control of a process or system”
Oxford English Dictionary

“Information about the result of a process
or action that can be used in modification
or control of a process or system”

11. The “Behavioral Wedge”
— “Unlocking Energy Efficiency in the US Economy”
— $1 trillion
— 20 gigatons of greenhouse gas
“…but only if the nation can craft a comprehensive and innovative
approach to unlock it.” (McKinsey & Company, 2009)
— “Household actions can provide a behavioral wedge to rapidly
reduce carbon emissions”
— 5-12% reduction in 5 years
— 9-22% reduction in 10 years
“…without waiting for new technologies or regulations or changing
household lifestyle.” (Dietz, Gardner, Gilligan, Stern, & Vandenbergh, 2009)

14. Looking at past research
— 100+ studies conducted since 1976
— Effect sizes ranged from -.0830 to .4803
— Mean r-effect size = .1174 (p < .001)
— Moderating variables:
— duration (longer = more effective)
— Frequency (more frequent = more effective)
— Medium (computer/device > paper)
Karlin 2012
15. Limitations of Studies
— Not naturalistic
— Participants recruited to participate
— May be different from “active adopters”
— Not comparative
— Most studies tests one type of feedback (vs. control)
— Very few commercial products in studies
— Not testing mediation
— DV is energy use, but studies rarely test possible
mediators to explain effectiveness
Karlin 2012
16. Present research
1. Identify ‘naturalistic’ users of feedback
— Who is really using these products?
— Purposive sampling
2. Ask about the user experience
— Enables comparisons between devices
— Gain insights into usability, adoption, etc.
3. Explore perceptions and barriers
— Understand market beyond the “early adopters”
— Identify potential barrier and leverage points

— Where did you get it?
Findings
— Social Diffusion (family/friends/colleagues)
— 20% learned about product through friend/family
— 14% received product from friend/family
— Utility acquisition (21%)
— Borrowing (13%)

Had no idea that these exist. The idea of it I find very appealing.
I have never heard about this kind of mechanism
as I have not been proactive in learning about it.

No because I don't feel its your business to tell me
what I can use or to monitor my opinions on the matter
Assume they make sense since the
utility companies are promoting them.
A wonderful idea!

Do not know how to install/set up 18%
Already conserving energy 16%
Never got around to it 15%

Do not see any benefit in using such a device 5%
Conserving energy is not a priority in my life 2%
they might not be
available in my area
I’m too busy to worry about
my energy consumption
I already keep track of many things in my life
and do not want to add another burden

“I often recommend it, but have a hard time convincing
others that it is worth the [money]”
Karlin 2012
“To induce behavior these devices have to
be free or very low cost.”
35. Our Study
Knowledge Persuasion Decision Confirmation
Karlin 2012
Did they adopt?
Confirmation factors:
1. Usability
2. Outcome
36. Confirmation
Usability
— What do you like / dislike about the product?
— What was your most surprising experience?
Outcomes
— Did knowledge, behavior, and/or energy use change?
— Do you still use this product?
Karlin 2012
37. Confirmation – positive
Usability
— Ease of use
— Effective energy information
Outcomes
— Correct inaccurate assumptions about energy use
— Both general and specific behavior change reported
We installed power strips to easily power off all
high energy items
Karlin, 2012
I had no idea how much energy computers used
38. Confirmation - negative
“Rebound Effect”
— 15% were surprised that they used less energy than they thought
Diminishing utility
“…I’ve actually wound up using more energy on some devices
when I see how little energy they use (my laptop, for one).”
— 48% said they do not still use the product
— No longer in possession/borrowed
— Do not see a need to continue using
“it’s served it’s purpose”
“I checked almost every device I have, so continued usage isn't
very informative unless I start tracking usage in a spreadsheet -
way too much work.”
Karlin, 2012
39. Implications
1. Further research into active feedback adopters could yield
positive results for segmentation.
2. Research into leveraging social networks to promote the use
of feedback devices is promising.
3. There is promise for utility-based and lending/borrowing
programs for distribution.
4. Integrating injunctive social norms (e.g. social comparison)
could address rebound effect.
5. Further research is needed into actual and perceived barriers
of potential users.
Karlin 2012
40. Closing Thoughts
“Energy efficiency is not just low-hanging fruit; it is fruit
that is lying on the ground.”
