Compared to 1990, Germany's GDP increased by 54% in 2019; renewable energy R&D expenditures increased by 99% and renewable energy use increased by 84811% (excluding hydro), while total energy consumption decreased by 14% and total energy losses 415%. In other words, Germany increased its use of renewable energy with its high income and managed to reduce its total energy consumption and total energy losses significantly. In the same period, France and Italy, which are partners between the G7 countries and the European Union countries, increased their total energy consumption by 7% and 0.71%. In comparison, Germany achieved a remarkable reduction of 14%. Therefore, the difference of this study from other studies is that the question of how Germany earned more income with less energy in the relevant period is investigated by econometric methods. In doing so, R&D expenditures made in renewable energy, non-renewable energy and nuclear energy were used for Germany from 1990 to 2019. For this purpose, the stability of the variables was investigated during the period examined by using Perron (1989) and Zivot and Andrews (1992) tests in which structural breaks were taken into account. Later, the long-term relationship was tested with the Gregory and Hansen (1996) cointegration test, and a cointegration relationship was found. Then, it was tested with estimators that structural changes such as the Developed Least Squares Method (FMOLS) and Canonical Cointegrated Regression (CCR) were included in the model as dummy variables for the long-term relationship. The findings show that the energy R&D expenditure for Germany that decreases the total energy use amount the most in the long term is the R&D expenditure for renewable energy. In contrast, the energy R&D expenditure that increases the most is the R&D expenditure for nuclear energy. Germany's increase in renewable energy R&D expenditures by 99% in 2019 compared to 1990 and decreased nuclear energy R&D expenditures by 45.46% supports the results obtained. Therefore, improvements in energy in Germany offer significant opportunities.

Almanya’nın 1990 yılına göre 2019 yılında GSYİH’sı %54, yenilenebilir enerji AR-GE harcamaları %99 ve yenilenebilir enerji kullanımı %84811(hidro hariç) artış gösterirken, toplam enerji tüketimi %14 ve toplam enerji kayıpları %415 oranında azalış göstermiştir. Yani Almanya yenilenebilir enerji kullanımını geliriyle beraber yüksek oranda artırmanın yanında toplam enerji tüketimini ve toplam enerji kayıplarını ciddi oranda azaltmayı başarmıştır. Ayrıca aynı dönemde G7 ülkeleri ve Avrupa Birliği ülkeleri arasında ortak olarak yer alan Fransa ve İtalya ülkeleri sırasıyla %7 ve %0.71 oranında toplam enerji tüketimini artırırken, Almanya ise %14 gibi dikkate değer bir oranda toplam enerji tüketimini azaltmayı başarmıştır. Dolayısıyla bu çalışmanın diğer çalışmalardan farkı Almanya’nın ilgili dönemde daha az enerjiyle nasıl daha fazla gelir elde ettiği sorusunun ekonometrik yöntemlerle araştırılmasıdır. Bunu yaparken Almanya için 1990-2019 döneminde yıllık verilerle yenilenebilir enerji, yenilenemez enerji ve nükleer enerji alanlarında yapılan AR-GE harcamaları kullanılmıştır. Bu amaçla yapısal kırılmaların dikkate alındığı Perron (1989) ve Zivot ve Andrews (1992) testleri kullanılarak incelenen dönem boyunca değişkenlerin durağanlığı araştırılmıştır. Sonra uzun dönem ilişkisi Gregory ve Hansen (1996) eşbütünleşme testi ile sınanmış ve eşbütünleşme ilişkisine rastlanmıştır. Daha sonra uzun dönemli ilişki için Geliştirilmiş En Küçük Kareler Yöntemi (FMOLS) ve Kanonik Eşbütünleşik Regresyon (CCR) gibi yapısal değişmelerin kukla değişken olarak modele dâhil edildiği tahmincilerle test edilmiştir. Bulgular, Almanya için uzun dönemde toplam enerji kullanım miktarını en fazla azaltan enerji AR-GE harcaması türünün yenilenebilir enerji için yapılan AR-GE harcamaları olduğunu, en fazla artıran enerji AR-GE harcamaları türünün ise nükleer enerji için yapılan AR-GE harcamaları olduğunu göstermiştir. Almanya’nın 1990 yılına göre 2019 yılında yenilenebilir enerji AR-GE harcamalarını %99 oranında arttırması ve nükleer enerji AR-GE harcamalarını ise %45.46 oranında azaltması elde edilen sonuçları desteklemektedir. Dolayısıyla Almanya için enerji alanında yapılan iyileştirmeler çok önemli fırsatlar sunmaktadır.
