Özet:Population increment, industrialization, and developments in technology cause increase in energy demand. In order to meet this demand, fossil fuels are used excessively despite being exhaustible and harmful to environment. It is necessary to decrease use of fossil fuels to meet energy need without causing burdens on environment. Thus, renewable energy sources such as wind, solar, biomass, and geothermal has been started to use significantly. From renewable energy sources wind energy has taken considerable attention to generate electricity due to being developed technology. Moreover, wind power plants (WPPs) are installed in many countries to benefit from clean source of electricity. Also, it is known that to meet increasing demand in peak hours energy storage has become crucial and many energy storage systems are utilized. Since environmental concerns have been risen over time, necessity of using environmentally friendly energy storage systems such as pumped storage hydropower (PSH) has been one of the major issues. In this dissertation, emissions of two environmentally friendly systems Gökçekaya PSH (not commissioned yet) and Metristepe WPP (commissioned) both located in Turkey are investigated and compared by using life cycle assessment (LCA) method. To vi carry out LCA studies, one of the most common software GaBi is used and CML impact categories are considered to evaluate emissions. In addition, to have comprehensive comparison of systems, cost of the systems are calculated and compared. Besides, whether these systems compensate their investments in 20 years lifetime or not is revealed.
