Six renewable technologies were identified, and the multi-criteria technique is used to select the most appropriate technology. Fourteen sub-criteria have their weights assessed by expert opinion and with the use of lhe Analytical HierarchyProcess methodology. The PROMETHEE-GAIA software (Preference Ranking Organization Method for Enrichment Evaluation) is used to prioritize and select the most preferred renewable energy technology. Six community energy indicators were also identified from the inclusion of community agents in the decision-making process. A comparison is carried out with the opinion of experts in the renewable energy field and community agents with regards to the weights and usefulness ol the technical, environmental, economic, and social criteria in the decision-making process.
