Abstract
This study aimed to evaluate the energy policies and investments in renewable energy resources. In this context, developing energy policy and investing in energy were defined as two different factors for renewable energy. Additionally, eight different criteria were also selected based on these two different factors. In the first stage of the analysis, these criteria were evaluated by using a correlation coefficient based on interval type-2 fuzzy sets. The findings show that five criteria have a relationship with policy factors, whereas seven criteria are related to the investment factor. After that, the fuzzy DEMATEL approach based on interval type-2 fuzzy sets were used to weight these criteria. It was identified that policy returns, policy facilities, and policy technology were the most important criteria. Additionally, a performance evaluation of renewable energy investment alternatives was made with a fuzzy TOPSIS approach based on interval type-2 fuzzy sets. It was concluded that wind and solar are the most significant renewable energy investment alternatives. Therefore, it is recommended that there should be government supports for wind and solar energy investments. Within this context, corporate tax discounts for these companies, customs duty decrease for the items used in the investments, and providing qualified personnel in this area can attract the attention of these investors.
Highlights
Renewable energy refers to the type of energy in which resources are not limited and can be renewed continuously [1,2]
The performance results of renewable energy investment alternatives are ranked as wind, solar, hydropower, geothermal, and biomass, respectively
It is concluded that five criteria have a relationship with policy factors, while seven criteria are related to the investment factor
Summary
Renewable energy refers to the type of energy in which resources are not limited and can be renewed continuously [1,2]. Because renewable energy has unlimited resources, it has attracted the attention of investors. In this circumstance, investors should focus on many different factors at the same time in order not to have a loss [3]. Geographical conditions, legislation, and climate factors are very important items in this investment decision process. Investors should make an analysis of the profitability and market conditions. Technological improvement should be provided for the countries to become successful in this process
