Good article about why plain switching to EVs isn’t the solution.

    Indeed. The sting is in the quoted study:

    electric vehicles (EVs) were found to be 24% heavier than equivalent internal combustion engine vehicles (ICEVs). As a result, total PM10 emissions from EVs were found to be equal to those of modern ICEVs. PM2.5 emissions were only 1–3% lower for EVs compared to modern ICEVs.

    This is definitely pretty counter-intuitive and a bit of a bummer. Turns out a very large part of particulate emissions comes from tires and brakes. I thought the regenerative braking used by EVs would help, but apparently not much. The reduction is surely bigger than 3% when compared to diesels, but still.

    That still leaves the non-particulate pollution, including carbon monoxide and NOx, EVs have none of that. And almost no noise pollution either, at least at low speeds.

    I have been to Shanghai and I can tell you that a city full of EVs is just much, much more pleasant. The air quality, the silence, it’s almost night and day. Replacing combustion cars with EVs is still a huge win, we should not lose sight of that.

    But yes, it’s not the solution. The solution is less cars.

      The solution is less cars.

      And less car (singular/measurement). Weight and size are multipliers to problems (including cost).

      Sure E-bikes are better (bikes are better than that, and walking is the best especially for mixed transit), but there should be incentives to drive the smallest cars. And the giant behemoths we have in the US are like 3-4 classes up, these are a problem all on their own.
