Evidence from Two Large Field Experiments that Peer Comparison Feedback can Reduce Residential Energy UsageIan AyresYale University - Yale Law School; Yale University - Yale School of Management Sophie RasemanYale University - Law School Alice ShihYale University - Law School July 16, 2009 5th Annual Conference on Empirical Legal Studies Paper Abstract: By providing feedback to customers on home electricity and natural gas usage with a focus on peer comparisons, utilities can reduce energy consumption at a low cost. We analyze data from two large-scale, random-assignment field experiments conducted by utility companies providing electricity (the Sacramento Municipal Utility District (SMUD) and electricity and natural gas (Puget Sound Energy (PSE), in partnership with a private company, Positive Energy/oPower, which provides monthly or quarterly mailed peer feedback reports to customers. We find reductions in energy consumption of 1.2% (PSE) to 2.1% percent (SMUD), with the decrease sustained over time (seven months (PSE) and twelve months (SMUD).
