Abstract

This work investigates the possibilities of renewable energy (RE) based interventions to build a sustainable community on a small island in Fiji. Yanuca Island is twenty kilometers away from the mainland (Viti Levu) with a population of approximately 210 people. Fishing is the main source of income for the villagers but with no electricity, storage of the catch is a huge challenge resulting in substantial losses. The village has no fresh water supply, and depends on rain water harvesting for cooking and drinking needs. The major challenge with current water supply is the frequent outbreaks of waterborne diseases, which are common in children and during the dry season, drinking water has to be carted from the mainland. Most islanders depend on kerosene lamps, small diesel generators and a few on portable solar lights for lighting. Use of fuelwood for cooking also poses a threat to the health of the community members as well as the degradation of environment.
The aim of this study is to investigate if Yanuca community would be able to satisfy most of its energy and drinking water needs using RE technologies. It involves an assessment of the RE resource potential on the island combined with the energy and water needs analysis of the community. A questionnaire based survey was carried out to assess the energy needs and priorities for the community. Based on the survey results, strategies are being developed to utilize available RE resources. A solar- battery hybrid mini grid system for electrical energy needs is being proposed to replace the defunct diesel generator. A solar thermal desalination system using F Cubed Carocells has been sized and installed to cater for drinking water needs of the community especially children who are vulnerable to waterborne diseases. A small solar powered refrigeration system has been established to support the income generation through enhanced fishing activities. A socio-economic study, through a questionnaire based survey and interviews will be carried out to determine the impacts of integrating strategies for energy access.
