Energy efficient lighting programs have been the most important source of residential energy savings for many utilities in Canada and the United States. The purpose of this paper is to examine the role and impact of various marketing activities on residential electricity savings for lighting. This paper has four main conclusions. First, utility residential lighting programs vary substantially in terms of the marketing mix. Second, for the programs examined, estimated average energy savings were 80.3 GWh per year. Third, an increase in any of the three factors in the marketing mix (DSM program budget, breath of the program product offering, depth of the incentives offered) statistically significantly increases program energy savings. Fourth, the average utility cost of conserved energy was $0.035 per kWh with a low of $0.005 per kWh and a high of $0.218 per kWh.
