This document describes an experiment conducted by an electric company to test two approaches to encouraging energy conservation among customers: 1) providing small digital displays in households to show current electricity use and estimated monthly cost, and 2) giving customers a chart and information to monitor electricity use from their outside meter. The company will conduct an experiment comparing these two approaches to a control group that only receives general energy consumption information. The summary describes how the experiment would use a randomized design involving 60 households willing to participate, with the households randomly assigned to the three groups to compare the approaches.
