Are EV’s Good for the Environment?

Pretty impressive breakdown of environmental impacts from EV vs ICE vehicles.

    Note that the top-of-line batteries are only 70% higher than Carbon impact of manufacturing.

    Tessum et al 2018 published in PNAS, finds that total life cycle emissions and pollution costs of EVs vs. the gasoline car they replace, shows that off the standard grid charging, the EV provides only a tiny advantage in total life cycle emissions, and a significantly worse pollution beyond GHG’s http://www.pnas.org/content/pnas/early/2014/12/10/1406853111.full.pdf Obviously, charging your EV off of rooftop solar will be much better and the obvious choice. The point is, for now, EVs aren’t providing the benefit many may think. Not to criticize going towards EV’s, so please don’t confuse me with FF apologist!

      What?

      Just glanced at it, but abstract says FF ICE even with ethanol *raises* environmental air quality problems by 80%, while EV’s *reduce* it by 50%.

    He says sell your FF car, but then someone else will be driving it. For example, my 16 year old Toyota with 200,000 km might go another 100,000 km (might sell for ~$1500 ?). I would save many tons of emissions by scrapping it instead. But then, fewer cars on the market might lead to more FF cars being manufactured.

    As some in the YT comments have pointed out, there is no estimate of the carbon profile of the gasoline before it goes into the tank. To move those molecules, you need pipelines and tankers and pumps (Oh my!).

    Then there is the long range thinking of buy pure electric and demand clean energy where ever you are. As we grow in numbers, the market demand itself changes the utilities.

    Refining oil to petrol is not in this calculation. Or is it included in the car emissions?

    When an EV battery fails it is often only one or two cells that fail. Tesla make replacing those one or two cells much more dificult than it should be. 1:Make the battery packs repairable.

    When battery packs loose capacity to the point they are not viable for a car they still hold a very significant charge. If these used battery packs were added together they would make an exceptional household storage system. 2: Use old car packs domestically.

    Where pollution levels are concentrated, battery vehicles keep pollution out of the city centre. 3: Reduced congestion taxes for EV’s.

    ICE cars suffer there worst wear and tear and use the most fuel in those first few miles after a cold start. People like me who drive less than five miles, turn if off let it get cold, then drive five miles home and repeat a few times a day should be encouraged to EVs.

    The cost of Uber and other ride share are now, for many people, much cheaper than owning a car.
