Abstract:

The energy that is produced without harm to the environment is one of the top issues that people today care about. Therefore, the view that renewable energy systems should replace traditional energy systems is high. One of the most important methods used to determine which renewable energy system is more sustainable for a region is life cycle analysis. Life Cycle Assessment (YDD) is a method that is widely used to study all the environmental impacts of energy production processes. This method consists of the study of the stages of production, construction, operating- maintenance and cleaning-return. In this study, two different renewable energy systems configurations were compared with the YDD method, and the life cycles were environmentally evaluated in order to deal with the four phases of the renewable energy systems studied. The first of the selected systems is the ground wind power plant, and the second is the sea wind power plant. For this purpose, the Bozcaada region has been chosen as a pilot area; with the land wind farming operated in Bozcaada since 2000 and the possible construction in the same area in order to take advantage of the wind potential of this region, the supermarine wind power plant has been studied. For both configurations, the Gabi software has been used to evaluate energy production processes from five to a grave. In order to compare economically, the cost of the life cycle (YDM) of both systems is calculated. Life Cycle Assessment (YDD) and Life Cycle Cost (YDM) analysis methods have been analyzed for both systems and compared these analyses as they can be practical methods in terms of determining the long-term economic and environmental impacts of different renewable energy systems considered for a region. In light of the findings obtained, the conclusion has been that, although the surface wind farming is a more expensive technology, it is a more environmentally friendly system (except acidification). As a result, it has been found that the sea wind plant is more environmentally suitable for the Bozcaada region.
