Evaluation of renewable energy sources in TR83 region by CRITIC based grey relational analysis approach

Abstract

One of the important factors of both regional progress and economic development is energy issue. As the demand for energy increases with the growing population, countries are developing various policies about the supply, distribution and sustainability of energy in planning energy investments. At this point, investments for renewable energy (RE) sources that will cause the least damage to the environment and can be transferred to future generations are increasing considering the climate change and greenhouse gas emission risks. The aim of the study is to analyze RE resources in TR83 region from a multi-criteria decision making (MCDM) perspective by presenting an application for evaluating RE investments. For this purpose, using the CRITIC based Grey Relational Analysis (GRA) approach, it was provided that the RE sources in TR83 region were evaluated and ranked with respect to their performance. While the CRITIC method allows an objective weighting for the criteria, GRA provides to find out the best alternative for problems which include missing information or uncertainty. According to the result of the method, it is observed that the province which is the best in point of RE investments at the regional level is Samsun.
