Now that we have been on the path of increasing use of electricity for personal transportation, researchers are beginning to be able to statistically link the benefits of EVs to reduced pollution and illness by zip code, and correlate with higher EV adoption rates.
This study looked at EV adoption by zip code in California (the state with the fastest EV adoption rate, providing the largest amount of relevant data) and showed that the zip codes with higher EV registration rates had measurably lower NOx pollution and lower Asthma-related ER visits as EV registrations increased.
This may feel like an obvious correlation to some of us, but it is useful to begin building the scientific body of work to support these claims. The immediate human benefits of the transition to clean energy may sometimes be understated if there is a lack of hard data.
