A social impact assessment which focused on a Hawaiian community's evaluation of social change and development is reported. The research occurred on the island of Moloka'i, which depends largely on imports for its energy sources, although it has a number of natural sources (biomass, wind, solar, and water power). Specifically, the study identified values of the community so that alternative energy options could be related to the residents' preferred way of life. The Galileo methodology, which translates differences in values to physical distances on computer-generated maps, was used to compare value structures of 219 residents with those of decision makers (the governor, state legislators, heads of major economic interests, and county officials). Of the 15 value concepts appearing on the questionnaire, the principal values separating residents and decision makers are "slow pace" and "Hawaiian culture" (crucial for residents) and "education and jobs" (emphasized by decision makers). Generally, residents endorsed electricity self-sufficiency as long as the values they embraced were not endangered. These results give indications of the scale, timing, and types of energy development that residents will find most acceptable. Used with other data, these cross-community differences can provide the context for dialogue among social groups concerning perspectives on possible futures. (KC)
