Recently, alternative energy based vehicles have drawn the attention of engineers specifically on the production of fully electric powered vehicles due to increased environmental awareness and fuel cost. As a result of difficulties in commercializing the vehicles, electric powered cars find an application area in public transportation. One of the solutions for public transportation is to use trolleybus system. This paper gives a comparison of Trolleybus system and existing Metrobus system in Istanbul, Turkey in terms of energy costs and CO2 emissions. The simulation results show that using Trolleybus system instead of Metrobus is much more economical based on the current prices. As for the emissions, the amount of CO2 for city centers and overall environment is evaluated.
