Comparative Analysis of Sustainable Solar Energy Use in the Context of Energy Policies: The Cases of Türkiye and Germany

The amount of energy consumption is one of the main criteria for technological and economic advancement in countries. In order to meet the increasing energy need, there is an increasing tendency towards renewable energy, which is an alternative to fossil fuels and sustainable. Countries are turning to solar power plants, which are safe, environmentally friendly, and sustainable energy sources, to protect themselves from the effects of a possible energy crisis. Türkiye, which is dependent on energy imports, is increasingly recognizing the importance of its renewable energy resource potential. Based on the generation obtained from investments in solar power plant construction and the number of sunshine days, it is observed that Türkiye has a twofold higher investment viability level compared to Germany. This study comparatively analyzes the support provided by Türkiye and Germany for photovoltaic (PV) plants, focusing on energy policies. Germany aims to reduce its dependence on imports by diversifying its energy sources in accordance with its articulated vision. The study concludes that distinctions have emerged between Türkiye and Germany in terms of solar energy generation, influenced by factors such as energy purchase prices, purchase guarantees, energy policies, access to financing, incentives, economic development, legal regulations, and costs. Utilizing these data, the study seeks to identify the shortcomings of Türkiye’s energy policies related to the generation of PV plants, thereby contributing to the existing literature in this field.
