Sustainable development of the Prefecture of Kephalonia
An optimisation methodology is applied on the islands of Kephalonia and Ithaca (Prefecture of Kephalonia) in Greece, where various Renewable Energy Sources (RES) can be found and could be exploited to satisfy part of their energy needs. These resources are examined and a case study is performed for Kephalonia that involves an application of specific mathematical tools that will lead to a set of energy solutions. Many scenarios of cases were examined where the requirements of certain end uses were increased and also cases where some of the renewable energy systems were not at the maximum of their potential.
Alternative scenarios of the utilisation of renewable energy sources in small prefectures: a case study in Lasithi Prefecture, Greece
The sector of Renewable Energy Sources (RESs) is growing very fast, with many innovations and applications becoming a reality. The continuous reduction of natural resources has forced all policymakers to turn to alternative energy sources. The total energy (oil and electricity consumption) consumed in the prefecture of Lasithi during the years 1997â€“2002 in correlation with the RES exploitation potential in the prefecture is the base of an analysis where RES methodologies are exploited to satisfy part of the prefecture's energy needs. Solar energy, wind energy, geothermal energy and biomass are examined and a case study is performed for Lasithi that involves an application of specific mathematical tools leading to a set of alternative scenarios. The objective of this work is the integration of environmentally friendly processes for the satisfaction of the energy needs of Lasithi Prefecture, paying attention at the same time to the financial viability of these systems.
A comparative study of critical factors influencing the renewable energy systems use in the Indian context
The use of renewable energy technologies in developing countries has steadily increased over the past few decades. The widespread use of renewable sources requires a greater understanding of the available options. In order to ascertain the quantum of acceptance of renewable energy sources in the context of possible deterioration of the environment, on account of the increased use of fossil fuels, a Delphi study had been conducted. The feedback from the study was collected and analysed, so as to arrive at a general consensus. By the year 2020, the renewable energy contribution is expected to be 25% of the total energy use in India. At that time, the main resources utilised would be biomass, wind and solar in the order of their quantum of use. Using skewness and rank correlation analysis the results of the Delphi study were studied. It is identified that price, equipment efficiency and technology are the critical factors for commercialising renewable energy sources as denoted by skewness coefficients of 11.6, 5.55 and 0.68, respectively. Rank correlation indicates that the correlation between biomass gasifier electric conversion and biogas electric conversion for lighting is positive, denoting the possibility of integration of the two systems. Similarly, it has been analysed for integrated systems in the area of cooking, pumping, heating, cooling and transportation. This study will help in the formation of strategies which will ensure the development of the optimal integrated energy systems for continuous power supply.
