Abstract
In this paper, citizen preferences for power supply visions were assessed using choice experiments. In particular, preferences for the composition of power generation including renewable energy and nuclear power were analyzed. We also investigated how the need and consciousness for electricity saving affected the preferences for power supply visions. The results indicated that a respondent group who felt negative about resuming the operations at nuclear power plants had discriminative preferences for attributes of the power supply visions, and that the priority of carbon dioxide emissions as a criterion for evaluating the power supply visions became lower when the composition of power generation was presented. Consciousness for electricity saving, as well as preferences for nuclear power generation, differed depending on regions of residence, while their relationship was similar among respondent groups who lived in the jurisdictional areas of the electric power companies that had experienced risks of demand-supply gaps.
