CMU team finds regional temperature differences have significant impact on EV efficiency, range and emissions

Green Car Congress

Among their findings is that the resulting regional differences in efficiency, range and emissions are large enough to affect adoption patterns and the energy and environmental implications of battery EVs relative to alternatives. For grid emission factors, they used a recent analysis by Graff Zivin et al.
