Ian Ayres, Sophie Raseman and Alice Shih (Yale University – Yale Law School , Yale University – Law School and Yale University – Law School) has posted Evidence from Two Large Field Experiments that Peer Comparison Feedback Can Reduce Residential Energy Usage on SSRN. Here is the 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, 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)).
