Small Islands Developing States (SIDS) are isolated and surrounded by ocean. The generation and use of energy resources are two very important aspects for the development of SIDS. Unfortunately, most of SIDS do not use their potential in respect of energy resources, and they as a result have to depend on the import of fossil fuels in order to meet their energy needs. This increases the overall vulnerability of SIDS as they have to depend on the rising or fluctuating fossil fuels prices. Some SIDS, especially in the geographically dispersed Pacific region, do not have proper access to energy whereas other SIDS struggle more with energy security issue. At the same time, SIDS are most vulnerable to the impacts and effects of climate change, as they are among the ones to be most severely affected in case of natural calamities and sea-level rise.Drawing on experiences from Fiji and Mauritius, this paper explains core elements related to energy access and security in SIDS, contextualizes and discusses barriers and list some of the strategies that may be used to ensure access to and a continuous supply of energy in SIDS. A situational analysis of two SIDS outlines their current energy situation and compares their energy policies to globally accepted criteria for SIDS policies as well as with each other. It is claimed that the diverging energy performances of Fiji and Mauritius cannot be explained by policies differences. The reasons for the varying energy performances may therefore lie in the administrative and institutional mechanisms used by the two countries in implementing their energy policies. Finally, to enable SIDS to reduce their overall vulnerability and become truly sustainable islands, it is recommended to undertake careful assessments of the particular local contexts under which island energy regimes operate.

Purpose -The aim of this paper is to identify the factors that are responsible for the slow development of the renewable energy sector in the Pacific Island countries (PICs), and suggest ways of overcoming them. Design/methodology/approach -The paper compares the energy situation in Australia and Germany to that in the PICs, and the state of energy development in the PICs to its African, Caribbean and Pacific (ACP) counterparts. Findings -The paper finds that policy frameworks are important pre-requisites to the development of renewable energy. In addition, the absence of a science and technology base in the PICs is a serious impediment to the development of the renewable energy sector in these countries. It is found that the PICs are lagging behind in policy frameworks and institutional capacity building requirements as compared to other ACP countries. Practical implications -Policy frameworks must be established as an essential pre-requisite to the development of renewable energy in the PICs. In addition, ways and means must be found to address the lack of proper attitudes amongst decision-makers to the value of a science base in development. Originality/value -The paper identifies the underlying impediments to the rapid development of the renewable energy sector in the PICs, and suggests what could contribute to the lack of an appropriate science base that is considered as a requirement to development.

Problem statement: The use of vegetable oils as a fuel in diesel engines causes some problems due to their high viscosity compared with diesel. Various techniques and methods are used to solve the problems resulting from high viscosity. Approach: One of the techniques is the preparation of a microemulsion fuel, called a hybrid fuel. In this study, hybrid fuels consisting of coconut oil, ethanol and octan-1-ol were prepared with an aim to test their suitability as a fuel for diesel engines. Density, viscosity and gross calorific values of these fuels were determined and the fuels were used to run a direct injection diesel engine. The engine performance and exhaust emissions were investigated and compared with that of diesel and coconut oil. Results: The experimental results show that the engine efficiency of the hybrid fuels is comparable to that of diesel. As the percentage of ethanol and/or octan-1-ol increased, the viscosity of the hybrid fuels decreased and the engine efficiency increased. The exhaust emissions were lower than those for diesel, except carbon monoxide, which increased. Conclusion/Recommendations: Hence, it is concluded that these hybrid fuels can be used successfully as an alternative fuel in diesel engines without any modifications. Their completely renewable nature ensures that they are environmentally friendly
