A Comparative Analysis for Taiwan’S Renewable Energy Using Mcdm Methods

In recent years, global warming is one of the most serious issues. Many countries have implemented the various policies and incentives to help reduce emissions and to promote the renewable energy development. Taiwan has almost no natural resources, 98% of total energy supply depends on imports. Thus, this issue in Taiwan has become increasingly important for the objectives of energy independence and reduction of gas emissions. This study using four Multi-Criteria Decision making Methods (MCDM), namely WSM, VIKOR, TOPSIS, and ELECTRE, to rank renewable energy sources. The four dimensions (economic, technical, environmental and social) 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 based on different renewable energy sources. Then, these MCDM methods are respectively used for the quantitative evaluation to obtain the ranking of all alternative. The purpose of the comparative analysis is to determine what different using various MCDM methods for a renewable energy sources assessment model. The applicability of different MCDM methods for the focused decision problem is investigated. In addition, the similarities in MCDM methods and contrasts the resulting rankings are addressed.
