电动汽车被赞为保护生态环境的解决方法,但新研究显示,相比燃气汽车,它们对污染产生的全面影响可能更糟。研究人员分析了整个美国的车辆废气排放,然后将燃气汽车和电动汽车对环境造成的伤害绘制成图。这些科学家在美国东部发现,相比加油站,给电动汽车充电一晚上对环境造成的伤害更大。这项由美国国家经济研究局负责的研究着眼于5种主要污染物,分别是碳、二氧化硫、氮、悬浮微粒和挥发性有机化合物。研究人员考 Electric vehicles are hailed as a solution to the ecological environment, but new research shows that their overall impact on pollution can be even worse than gas cars. Researchers analyzed vehicle emissions across the United States and then plotted the environmental damage caused by gas and electric cars. These scientists found in the eastern United States that charging an EV a night harms the environment more than a gas station. The study, conducted by the National Bureau of Economic Research, looks at five major pollutants: carbon, sulfur dioxide, nitrogen, aerosols, and volatile organic compounds. Researchers test
