博士 === 長庚大學 === 企業管理研究所博士班 === 105 === In recent years, global warming is one of the most serious issues. Many countries have implemented various policies and incentives to reduce emissions and to promote the renewable energy development. Taiwan has almost no natural resources, 98% of total energy supply depending on imports. This issue has become increasingly important in Taiwan for the objectives of energy independence and reduction of gas emissions. Four Multi-Criteria Decision Making Methods (MCDM), namely WSM, VIKOR, TOPSIS, and ELECTRE are used to rank renewable energy sources. The four dimensions and ten decision criteria are used to evaluate the priority of five possible renewable energy sources in Taiwan. First, the weights of these criteria are calculated using entropy method for different renewable energy sources. The results show that technical is the most crucial dimension, followed by economic, environmental and social dimension. Efficiency is the most important criterion. Then, these four MCDM methods are used to evaluate the ranking of all alternatives. The purpose of the comparative analysis is to determine what different using various MCDM methods for a renewable energy sources assessment model. The results show that the ranking of these four MCDM methods were almost the same: hydro power is the best choice for Taiwan, followed by solar PV, wind, biomass and geothermal. Furthermore, the sensitivity analysis was conducted to reveal the ranking of alternatives changes due to variation of criteria weights. The results of this study can be provided to decision makers as a reference for the development of renewable energy.
