Life Cycle Assessment of EVs Reveals Startling Results

Thanks for this informative article. Just for the sake of argument: Let’s assume that mileage of conventional vehicles will continue to improve over time. Do these studies take that into account? Second, I also suspect that biofuels may continue to play a larger role; it is debatable that they reduce emissions as compared to petroleum fuels, but assuming that the role of biofuels continues to expand (and that biofuels do in fact have a smaller carbon footprint than petrofuels [debatable]), and that the efficiency of conventional vehicles continues to improve, might not conventional fuel vehicles be a better option in the long run? Of course, if EVs only charged during off-peak hours, those emissions would be burning anyway, so EVs would simply be capturing energy that would otherwise go to waste, which is another matter to consider. It doesn’t really seem fair to charge th...
