Abstract
Examines the effectiveness of non-monetary nudges on household energy consumption. The study evaluates the impact of Opower reports, which compare a household's electricity usage to that of their efficient neighbors and provide a qualitative rating (e.g., 'Great' or 'Good').
Methodology
A large-scale randomized controlled trial (RCT) spanning over 600,000 households across multiple utility markets in the United States, utilizing longitudinal energy billing records.
Findings
The neighbor comparison letters reduced electricity consumption by an average of 2.0%, equivalent to a 5% to 20% price increase, proving that peer comparison and social proof are highly cost-effective behavioral intervention levers.
Applied nudge
Add ambient peer-performance benchmarking dashboards (e.g., 'You use 15% less storage than similar accounts') to foster pride and encourage sustainable patterns.
