Why EVs Aren't a Climate Change Panacea

Cars That Think

JANUARY 28, 2023

“Electric cars will not save the climate. This is not to imply in any way that electric vehicles are worthless. For instance, Alexandre Milovanoff at the University of Toronto and his colleagues’ research (which is described in depth in a recent Spectrum article ) demonstrates the U.S. billion to more than 2 billion.
