Electric vs Gas

An idling gas engine may be annoyingly loud, but that’s the price you pay for having WAY less torque available at a standstill.

    EVs are also a major issue for firefighters. Lithium ion battery fires following an accident are ridiculously hard to put out and present a significant safety hazard in confined spaces, like tunnels or narrow streets. It takes close to 6 times the water to control EV vehicle fires.

    And while it’s a more minor issue, EVs are heavier than ICE vehicles in the same class, which causes more road wear and more tire wear (and more micro plastics to enter the environment).

    And, I guess, finally, there’s no established break-even point for carbon emissions over ICE vehicles. The estimates provided in the literature vary wildly–from 13,000 miles to 94,000.

    I love the technology, but I hope solid state batteries become a viable option for EVs.

      Easy solution is to move to Indiana. Our environment means that almost every day from November through April, the temperatures will be in the 30s-50s in the day and 10-20 at night, so the pavement is constantly cracking. Combine that with the lack of investment in infrastructure (Indy literally has a ban on new streetlights and stop lights going back to the 80s) and it doesn’t matter how heavy the car is, the pavement will be just as broken.

      I’ll buy more tire wear and microplastics, but argue the reduction in carbon emissions still makes it a better choice. However I don’t think there’s a noticeable difference in road wear. We’ve all heard the claim that road wear increases dramatically with weight, but compared to large trucks, EVs are still in the category of “close to zero”

      no established break-even point for carbon emissions over ICE vehicles. The estimates… vary wildly–from 13,000 miles to 94,000.

      I once read an article that I wish I kept, that addressed this (for US) by calculating per state, based on each state’s typical energy portfolio. While you’d really need your local energy portfolio, state level really improved accuracy and gave something you could use.

      West Virginia and Wyoming really stood out. As the two states still getting most of their electricity from coal the break-even is further out - I think it was as long as 14 years typical driving. Don’t buy an EV yet if you live in those states, unless you have solar.

      Several states with more renewables or nuclear, had break-even as low as 2 years typical driving.

      For most of us, the breakeven is low enough to consider the switch. It’s important to remember that electricity generation is getting cleaner all the time, even in Wyoming, so it’s quite likely the break-even point will move toward you over the years of owning a vehicle
