Bu çalışma yeşil büyüme stratejisi çerçevesinde değerlendirilen değişkenlerin G-7 ülkelerinin enerji verimliliği üzerindeki etkilerini araştırmaktadır. 1990-2020 dönemleri arası yıllık verilerinden faydalanılmıştır. Enerji verimliliği hem büyüme süreçleri hem de çevresel sürdürülebilirlik açısından oldukça önemli bir konudur. Bu kapsamda sürdürülebilir kalkınma hedefleri kapsamında enerji verimliliği üzerinde etkili olabileceği düşünülen değişkenler çalışmada kullanılan modele dâhil edilmiştir. Yeşil büyüme, yeşil teknoloji olarak kabul edilen çevre ile ilgili teknolojiler, yenilenebilir enerji arzı ve kaynak verimliliği değişkenlerinin enerji verimliliği üzerindeki etkisi değerlendirilmiştir. Değişkenler arasındaki ilişkiyi tespit edebilmek için CS-ARDL tahmincisi kullanılmıştır. Ampirik uygulama sonuçları yeşil büyümenin enerji verimliliğini artırdığını gösterirken, kaynak verimliliğinin enerji verimliliğini azalttığını göstermiştir. Öte yandan yeşil teknoloji ve yeşil enerji arzı değişkenleri ile bağımlı değişken arasında istatistiki olarak anlamlı bir ilişki gözlemlenememiştir. G7 ülkelerinde yeşil enerji ve teknolojilerinin bölgesel düzeyde farklılık gösterebilecek olması literatürden beklenen genel etkilerin değişebilmesine yol açabilmektedir. Ayrıca G7 ülkelerinde Rebound (geri tepme) etkisi, politik ve piyasa uyumsuzlukları, enerji kaynaklarının çeşitliliği, bölgesel dağılım sorunları gibi faktörler sonuçların her ülkede farklılaşmasına yol açabilecektir. Bu nedenle bulguların her ülkenin dinamikleri doğrultusunda ele alınması son derece önemli olacaktır. G7 ülkelerinde yeşil büyüme ve enerji verimliliğini artırıcı yönde Rebound etkisinin azaltılması, yeşil teknolojilerin ar-ge yatırımlarının artırılması, enerji depolama, iletim altyapılarının enerji verimliliğini teşvik edecek şekilde tasarlanması vs. politikaların çok önemli olacağı önerilmektedir.

Investigating the Effect of the Green Growth Process on Energy Efficiency: A Study on G-7 Countries

Öz

This study investigates the effects of variables evaluated within the framework of green growth strategy on energy efficiency of G-7 countries. Annual data between 1990-2020 were used. Energy efficiency is a very important issue in terms of both growth processes and environmental sustainability. In this context, variables that are thought to have an effect on energy efficiency within the scope of sustainable development goals were included in the model used in the study. The effects of green growth, environmental technologies accepted as green technology, renewable energy supply and resource efficiency variables on energy efficiency were evaluated. CS-ARDL estimator was used to determine the relationship between the variables. Empirical application results showed that green growth increases energy efficiency, while resource efficiency decreases energy efficiency. On the other hand, no statistically significant relationship was observed between green technology and green energy supply variables and the dependent variable. The fact that green energy and technologies may differ regionally in G7 countries may lead to changes in the general effects expected from the literature. In addition, factors such as rebound effect, political and market incompatibilities, diversity of energy resources, regional distribution problems in G7 countries may cause the results to differ in each country. Therefore, it will be extremely important to consider the findings in line with the dynamics of each country. It is suggested that policies such as reducing the rebound effect, increasing R&D investments in green technologies, designing energy storage and transmission infrastructures to encourage energy efficiency, etc. will be very important in G7 countries in order to increase green growth and energy efficiency.
