    Economic indicators and bioenergy supply in developed economies: QROF-DEMATEL and random forest models
    (Elsevier, 2022) Bhuiyan, ?Miraj Ahmed; Dinçer, Hasan; Yüksel, Serhat; Mikhaylov, Alexey; Shah Danish, Mir Sayed; Pintér, Gábor; Uyeh, Daniel Dooyum; Stepanova, Diana
    Bioenergy is a renewable energy source that saves from fossil fuel dependence. Therefore, it is important to increase the efficiency of bioenergy investments to create an environmentally sustainable energy supply. This paper aims to identify economic indicators significant in forecasting the supply of bioenergy. Considering this goal, an integrated evaluation has been performed for 17 developed economies using the Random Forest method and the Fuzzy Decision-Making Trial and Evaluation Laboratory (QROF-DEMATEL) method. The main contribution of this study is conducting analysis by using both quantitative and qualitative data. Additionally, the coherence of the results made with the QROF-DEMATEL method is also verified by implementing a sensitivity analysis. The results of both approaches are quite similar and provide information about the reliability of the findings. This situation demonstrates that for the development of bioenergy investments, firstly, countries’ macroeconomic conditions should be improved. Consequently, economic growth and unemployment (weighting results - 0.159 and 0.155) should be primarily considered for the bioenergy supply forecast.

    The role of hydrogen in the black sea for the future energy supply security of Turkey
    (IGI Global, 2021) Yüksel, Serhat; Mikhaylov, Alexey; Ubay, Gözde Gülseven; Uyeh, Daniel Dooyum
    In this study, the importance of hydrogen sulfide resources in the Black Sea region for future energy supply security has been analyzed. In this context, Turkey has been the scope of review. Through the world's largest hydrogen sulfide deposits in the Black Sea region with which hydrogen can be used effectively in the production of this resource, Turkey will be able to meet the annual energy needs face. This will provide benefits to many aspects of Turkey's economic development. Turkey's current accountdeficit, which would import energy problem, can also be reduced. This situation will contribute to reducing the fragilities in the country's economy. In this respect, Turkey should give priorities for the hydrogen sulphide reserves in the Black Sea. In this framework, detailed studies should be conducted on the conditions of the region.
