Abstract

This study aims at evaluating the environmental impacts in the hydroelectric power generation. The environmental impacts was assessed from impact categories such as abiotic resource depletion(ARD), global warming(GW), acidification(AD), eutrophication(EU), ozone depletion(OD), and photochemical ozone creation (POC). The most impact categories for hydroelectric power generation is global warming potntials (67%). The most life Cycle stage for hydroelectric power generation is step before manufacturing stage (94%). The significant environmental aspects in step before manufacturing stage were related with Dam(75.4%), power plant(6.3%) and used electric power(6.3%).
