An analysis of residents' preferences on electricity generation by source and their factors

A questionnaire survey to was carried out to Tokyo metropolitan area residents and their preferences and the factors on future electricity generation by source (EGS) were analyzed. Four clusters of ideal EGS were observed; C1: preferring renewable energy from viewpoints of Safety and Global Warming, C2: preferring thermal power generation from Safety and Energy Security, C3: preferring nuclear power generation from Energy Security and Economic Efficiency and C4: preferring mixed use from Energy Security and Safety. In feasible EGS, much of renewable energy and nuclear power generation were replaced by thermal power generation. This indicates that residents would have willingness to accept the power generation mix strategy. The level of residents' understanding of each power generation features still remain less interpretable. For the consensus building on the power generation mix strategy, providing detail information of each power generation features is required. (author)
