Solar photovoltaic (PV) on atolls: Sustainable development of rural and remote communities in Kiribati

On the remote and geographically fragmented atolls of Kiribati (Republic of), imported petroleum products are the main sources of energy. The other sources of energy utilised include biomass, solar energy and wind power. Of these three renewable energy sources, biomass is the most, and wind power is the least, exploited in terms of the contribution it makes to the total primary energy supply. Solar energy makes a very insignificant contribution to the total primary energy supply in Kiribati. Petroleum products, biomass and solar energy contribute approximately 75%, 25% and less than 1%, respectively to the total primary energy supply annually. Solar energy has been exploited mostly in the form of photovoltaic (PV) technologies for the provision of lighting.The geographical, social, economic and political situation in Kiribati is considered in this paper to give an overview of the country. The current energy situation in Kiribati is presented with emphasis on the application of PV technologies. Some recommendations that will promote sustainable development of the rural and remote communities on the outer atolls of Kiribati, through the use of PV technologies, are also presented in this paper.
