Abstract

Inclement weather and climate change have created a sense of crisis that greenhouse gases must be reduced, and electric cars have been considered an eco-friendly means because they do not generate greenhouse gases except for the stage of generating electricity for charging and harmful exhaust emissions. In this study, by analyzing the digital tachograph data, the effects of converting a fleet of taxis operating in Gwangju to electric cars were calculated in terms of energy consumption, CO2 generation, and cost. As a result of the study, it was calculated that if the market share of electric vehicles increases by 5%, the average daily electricity consumption increases by 9.9MWh, and the LPG consumption and CO2 emission decrease by 7.3m3 and 10.8ton, respectively. Looking at the effect of 2044, assuming that all private taxis will be converted to electric cars, 108 tons of CO2 can be reduced, which is 36.0% compared to 2022, and the cost will be reduced by 26.0%, which is 38.8 million won compared to 2022. If this is aggregated on a one-year basis, it is analyzed that a total of 39,524 tons of CO2 can be reduced and a total of 14.2 billion won in cost can be saved in 2044 compared to 2022.

전 세계적인 이상 기후 현상은 온실가스를 감축해야 한다는 위기의식을 만들었으며 온실가스 총 발생량의 상당 부분을 차지하고 있는 수송부문에서 전기자동차는 충전을 위한 전기를 발생시키는 단계를 제외하고는 온실가스를 발생시키지 않고 다른 유해한 배기가스를 발생시키지 않는다는 점에서 친환경 수송수단으로 여겨지고 있다. 본 연구에서는 디지털운행기록계 자료를 분석하여 광주광역시에서 운행하고 있는 택시를 전기자동차로 전환하였을 때의 효과를 에너지 소모량, CO2 발생량, 비용 측면에서 산정하였다. 연구결과 전기자동차 점유율이 5% 증가하면 평균적으로 하루 전기 사용량은 9.9MWh 증가하고, LPG 사용량과 CO2 방출량은 각각 7.3m3과 10.8ton 감소하는 것으로 산정되었다. 전체 개인택시가 전기자동차로 전환될 것으로 가정한 2044년의 효과를 살펴보면, CO2의 경우 2022년 대비 36.0%에 해당하는 108ton을 저감할 수 있으며, 비용은 2022년 대비 26.0%인 38.8백만 원을 절감할 수 있는 것으로 분석되었다. 이를 1년 단위로 집계할 경우 2044년에는 2022년 대비 연간 총 39,524ton의 CO2를 저감하고, 비용은 총 142억 원을 절감할 수 있는 것으로 분석되었다.
