研究发现,EVs由于缺乏可再生能源,致使26个国家的CO2排放量增加。 Study finds EVs increase CO2 emissions in 26 countries due to lack of renewable energy sources.

奥克兰大学和Xiamen大学研究人员最近进行的一项研究发现,在过去15年中,26个国家采用电动车辆与二氧化碳排放量的增加有关。 A recent study by researchers from the University of Auckland and Xiamen University found that electric vehicle (EV) adoption in 26 countries has been linked to increased CO2 emissions over the past 15 years. 研究表明,只有可再生能源占一个国家电力组合的48%左右时,EV才会减少排放量。 The study indicates that EVs only reduce emissions if renewable energy makes up about 48% of a country's electricity mix. 目前,可再生能源只占全球电力的30%。 Currently, renewables account for only 30% of global electricity. 研究人员建议,为了从EVs中受益,各国政府需要通过雄心勃勃的目标和补贴来增加可再生能源的使用。 The researchers suggest that to benefit from EVs, governments need to boost renewable energy use through ambitious targets and subsidies.
