In the world in which we live, the energy requirement increases in a certain way, and studies on clean and renewable energy sources become important. Renewable energy sources ensure sustainable energy use, and at the same time, damage to the environment is minimized with these resources. 20% of the energy consumed in the world today is obtained from renewable sources. Although the consumption of fossil resources seems to be excessive in this case, the potential for using renewable resources increases over the years. As a result of the fact that countries meet their needs with their domestic resources by reducing their external dependence in the long term, energy bills are significantly reduced and benefits are provided in many areas, from national income to employment, environmental factors, energy supply security to resource diversity. In order for an energy source to exist, parameters such as the capacity of these resources, their adaptation to the environment, economic factors and their continuity must be taken into account. In the study, the importance of evaluating the energy potential, which is very important for humanity, more effectively and efficiently, meeting the increasing energy needs with alternative energy sources and minimizing the damage to the environment was mentioned. With the example of the city of Freiburg, it was desirable to attract attention to the impact of the production of renewable energy sources on the development of the country.
