Energy Sector

Residential Energy Conservation via Neighbor Benchmarks

Percentage Household Energy Savings moved from 0.1% to 2.1% — a +2.0 percentage-point (2000% relative) change (sample: 600,000 households).

Study details

Challenge
Traditional educational brochures advising consumers to turn off appliances had zero measurable impact on electrical grid conservation.
Intervention
Opower printed a peer-comparison chart on monthly utility bills, grading energy usage against efficient neighbors and rewarding efficiency with simple emoticons (smiley faces).
Outcome
Percentage Household Energy Savings: 0.1% (control) → 2.1% (treatment); +2.0 pts, 2000% relative
Sample
600,000 households
Key takeaway
Peer benchmarking induces healthy competition and social validation. The addition of emotional feedback (smiley faces) prevents efficient users from experiencing the 'boomerang effect' (increasing usage toward the average).
