Empowering remote island communities with renewable energy : a preliminary study of Talaud Island

Following a rise in population, load demand is increasing even in the remote areas and islands of Bangladesh. Being an island that is also far from the mainland of Bangladesh, St. Martin’s is in need of electricity. As it has ample renewable energy resources, a renewable energy-based microgrid system seems to be the ultimate solution, considering the ever-increasing price of diesel fuel. This study proposes a microgrid system and tests its technical and economic feasibility in that area. All possible configurations have been simulated to try and find the optimal system for the island, which would be eco-friendly and economical with and without considering renewable energy options. The existing power supply configuration has also been compared to the best system after analyzing and investigating all technical and economic feasibility. Sensitivity and risk analysis between different cases provide added value to this study. The results show that the current diesel-based system is not viable for the island’s people, but rather a heavy burden to them due to the high cost of per unit electricity and the net present cost. In contrast, a PV /Wind/Diesel/Battery hybrid microgrid appeared to be the most feasible system. The proposed system is found to be around 1.5 times and 28% inexpensive considering the net present cost and cost of energy, respectively, with a high (56%) share of renewable energy which reduces 23% carbon dioxide.

Island Community

Purpose – The purpose of this paper is to discuss and use living stories to provide examples and some basic principles of cooperation as the alternative way of organising island community. Design/methodology/approach – This study draws upon autoethnography and storytelling to show co-operative practices. Storytelling is supported by deconstruction of living stories. Findings – Island communities create and maintain resistance through a culture of cooperation. Living stories (I-V) illustrate different instances of cooperative practices, for example, friends in need, gathering, search and moba, and where sympathy, gift, and humanity and care are essential elements. Research limitations/implications – It would be interesting to explore whether island communities elsewhere exhibit similar patterns. Practical implications – Deconstructed stories helped in reconstructing the bigger picture of how the people on the island offer collective resistance by developing different ways of cooperation. Social implications – Living stories (I-V) based on reciprocity of taking turns and giving back to the community, is a strategy for survival and of collective resistance within the rural island communities. Originality/value – Appreciation of the true value of collective resistance based on gift and reciprocity rather than financialisation and economisation aids to better understanding of the needs of traditional societies of island archipelagos, on the part of policy makers and other stakeholders who are involved in the process of planning for island development.

Haemolysis Test

SUMMARYThe single radial haemolysis test is conveniently practical and economical and promises to have wide applicability in the study of influenza antibodies in human populations. It can also be adapted for preliminary examination of new virus isolates during epidemics.Using this test a rather higher proportion of the population in the Highland Region of Scotland was found to possess antibody to a recent epidemic strain of influenza (A/Scotland/74) than was the case in the south of England. Antibody was detected and apparently evenly spread throughout all but the most remote island communities. Some evidence of the spread of the subsequent variant, A/Victoria/75, was obtained. Most of the school children in our study had high antibody titres to recent strains but the proportion with high antibody titres to these strains declined speedily from the age of 17 years onwards.

Este artigo evidencia um estudo preliminar de dimensionamento de um parque eólico com base nos dados obtidos pelo INMET – Instituto Nacional de Meteorologia apresentando os conceitos aplicados para a geração de energia sustentável. Propõe-se um estudo que apresenta a implantação de um parque eólico em uma região do Espirito Santo, comparando a média de velocidade dos ventos anuais em cada região (Linhares e Presidente Kennedy), analisando qual região será mais viável a implantação, a escolha do modelo de aerogerador e a análise da melhor eficiência para implantação do parque eólico. Os resultados obtidos mostram que o munícipio de Presidente Kennedy apresenta o melhor potencial para o dimensionamento do parque visto que apresenta a melhor estabilidade na direção dos ventos (Nordeste seguido de Leste-Nordeste) e a melhor média de velocidade de 3,7m/s. A partir da escolha da região foi escolhido o aerogerador para o parque (modelo Enercon E-82/2000KW com torre de concreto de 98 metros), e calculado a melhor eficiência que o parque poderá operar que é de 75,095%. Operando-se nessa eficiência o parque contará com 27 aerogeradores distribuídos em três fileiras numa área de 8000m2 podendo produzir uma energia anual em torno de 74079,183 MWh.Palavras-chave: parque eólico, aerogerador, eficiência. RENEWABLE ENERGY: PROPOSAL FOR WIND FARM SCALING OF ESPÍRITO SANTOABSTRACT: This article shows a preliminary study of the design of a wind farm based on data obtained by INMET - National Institute of Meteorology presenting the concepts applied for the generation of sustainable energy. It is proposed a study that presents the implementation of a wind farm in a Espirito Santo region, comparing the average speed of the annual winds in each region (Linhares and Presidente Kennedy), analyzing which region will be more feasible the implantation, the choice of Wind turbine model and the analysis of the best efficiency for the implementation of the wind farm. The results show that the municipality of Presidente Kennedy presents the best potential for the dimensioning of the park since it presents the best stability towards the winds (Northeast followed by East-Northeast) and the best average speed of 3.7m / s. From the choice of the region, the wind turbine was chosen for the park (model Enercon E-82 / 2000KW with a concrete tower of 98 meters), and the best efficiency that the park can operate is calculated to be 75.095%. Operating in this efficiency the park will have 27 wind turbines distributed in three rows in an area of 8000m2 and can produce an annual energy around 74079,183 MWh.Keywords: wind farm, wind turbine, efficiency.
