In this study, it is aimed to determine the most suitable renewable energy alternatives that can be used in blockchain investments. In this context, firstly, a wide literature review is made and 6 different criteria that could have an impact on this decision are determined. The analysis process of the consists of two different stages. Firstly, the significance levels of these criteria are calculated with the help of interval type-2 (IT2F) decision making trial and evaluation laboratory (DEMATEL)-analytical hierarchy process (ANP) (DANP) method. According to the analysis results obtained, it has been determined that continuity in energy supply and legal conditions are the most important criteria. Hence, it is recommended that while choosing among renewable energy alternatives, it is necessary to pay attention to the legal regulations in the country. Another important point is that attention should be paid to this issue in renewable energy sources to be selected in order to have sustainable benefit from energy in blockchain technologies. On the other hand, in the second phase of the analysis process of the study, 5 different renewable energy alternatives are listed according to their suitability in blockchain technology. In this process, the IT2 fuzzy VIšeKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) approach has been taken into consideration. As a result, it is concluded that wind and solar energy are the most suitable energy alternatives for this technology. Considering the results obtained, it is understood that countries that use blockchain technology should pay particular attention to wind and solar investments. In this regard, companies that use wind and solar energy with individuals or institutions using blockchain technology should be in cooperation. Thanks to these renewable energy alternatives, excess energy consumption resulting from the use of blockchain technology can be achieved with environmentally friendly energy sources. In other words, it will be possible to minimize the carbon emission problem that occurs with the use of this technology.

选择绿色区块链投资的可再生能源替代品:基于IT2的混合模糊建模

本研究旨在确定可用于区块链投资的最合适的可再生能源替代品。在这种情况下,首先,进行了广泛的文献综述,并确定了可能影响该决策的6个不同标准。的分析过程包括两个不同的阶段。首先,借助间隔2型(IT2F)决策试验和评估实验室(DEMATEL)-层次分析法(DANP)方法计算这些标准的显着性水平。根据获得的分析结果,已确定能源供应的连续性和法律条件是最重要的标准。因此,建议在选择可再生能源替代方案时,有必要注意该国的法律法规。另一个重要的一点是,应该注意选择可再生能源中的这个问题,以便从区块链技术中获得可持续的能源收益。另一方面,在研究分析过程的第二阶段,根据其在区块链技术中的适用性列出了5种不同的可再生能源替代品。在此过程中,已经考虑了IT2模糊VIšeKriterijumskaOptimizacija I Kompromisno Resenje(VIKOR)方法。结果,得出的结论是,风能和太阳能是该技术的最合适的替代能源。考虑到获得的结果,可以理解使用区块链技术的国家应特别注意风能和太阳能投资。在这方面,与使用区块链技术的个人或机构一起使用风能和太阳能的公司应进行合作。归功于这些可再生能源的替代,使用环保能源可以实现因使用区块链技术而产生的多余能源消耗。换句话说,可以使使用该技术时发生的碳排放问题最小化。
