Türkiye'de Yenilenebilir Enerji Tüketiminin Ekonomik Büyüme Üzerindeki Asimetrik Etkileri (The Asymmetric Effects of Renewable Energy Consumption on Economic Growth in Turkey)

Turkish Abstract: Ekonomik buyume ve kalkinma tum dunya ulkelerinin en temel amacidir. Artan enerji talebinin onemli bir kismi birincil enerji kaynaklarindan karsilanmasina ragmen, son yillarda yenilenebilir enerji kaynaklarinin uretim ve tuketimi de giderek artmaktadir. Bu calismanin amaci yenilenebilir enerji tuketiminin ekonomik buyume uzerindeki asimetrik etkilerini ampirik olarak analiz etmektir. Turkiye‟nin 1965-2017 donemine ait verileri kullanilarak yapilan analizde, dogrusal olmayan gecikmesi dagitilmis otoregresif model kullanilmistir. Calismada ayrica, duraganligi test edilebilmek amaciyla, ADF, PP, Ng-P ve KPSS birim kok testlerinin yani sira Zivot ve Anders tarafindan gelistirilen yapisal kirilmali birim kok testi kullanilmistir. Elde edilen bulgulara gore, degiskenler fark duragan olarak bulunmus ve iki degisken arasinda uzun donemde asimetrik bir iliski tespit edilmistir. Ayrica bulgulara gore, yenilenebilir enerji tuketimi ile ekonomik buyume arasinda dogru orantili bir iliski vardir. Ancak yenilenebilir enerji tuketiminde meydana gelen pozitif ve negatif soklar, buyume uzerinde asimetrik etkiler ortaya koymaktadir. Calismada yenilenebilir enerji tuketimindeki pozitif soklarinin etkisinin, negatif soklarin etkisine gore daha kucuk oldugu bulunmustur. Yenilenebilir enerji tuketimindeki yuzde birlik artis ekonomik buyumeyi yaklasik olarak yuzde 0.4 oraninda artirirken, yuzde birlik azalislar buyumeyi yuzde 0,7 oraninda azaltmaktadir. English Abstract: Economic growth and development is the main aim of all countries worldwide. Although an important part of the increasing demand is met by primary energy sources, the production and the consumption of renewable energy sources have risen in recent years. The objective of this study is to empirically analyze the asymmetric effects of renewable energy consumption on economic growth. In the analysis conducted using Turkey's 1965-2017 period data, the nonlinear autoregressive distributed lag (NARDL) model was used. In addition to the classical unit root tests such as ADF, PP, Ng-P and KPSS, structural break unit root test, proposed by Zivot and Anders was used in order to test stationary. According to the results of unit root tests, the variables were stationary in the first degree, and an asymmetrical relationship between the two variables was determined in the long-run. Moreover, according the findins, there is a direct correlation between renewable energy consumption and economic growth. However, positive and negative shocks in renewable energy consumption have asymmetric effects on growth. In the study, it has found that the impact of positive shocks in renewable energy consumption was smaller than the effect of negative shocks. The one percent increase in renewable energy consumption increases economic growth by approximately 0.4 percent, while the one percent fall decreases growth by 0.7 percent.
