Hi everybody,
When we discuss pollution due to vehicles, we have to be aware that the problem is in the cities, where the concentration of vehicles are very high. The high number of vehicles in a small place like a city, creates "hotspots" of pollution. So if we can replace legacy vehicles with Electric Vehicles (EV), then we would be able to reduce the pollution in the cities.
As for the overall pollution of the whole world, whenever the EV gets charged, then the pollution moved to the electric generation point. The quantum of pollution is open to argument. But we have to realise that the generation plant has efficiencies of up to 70%, whereas the individual vehicle engine would have efficiencies of about 30%. In this sense, for an equal amount of energy used in the vehicles, you have to burn more petroleum to run the legacy internal combustion engine.
AS for the resources required to make the batteries for EVs, I am not sure how much more pollution would be created compared to legacy vehicles. The article above says the point of return (when pollution becomes equal) is 80,000 miles. I yhink it should be a lot less than that. But I am not sure. More research is needed for this.
