  • These figures are also heavily dependent on where and how the car was manufactured, too. If the factory is powered by clean energy, doesn’t that reduce the amount of greenhouse gas emitted during manufacturing? If EV tech advances enough that the mining rigs are electric-powered, does that not also reduce the amount of GHG emitted mining lithium? Eventually we’ll also have enough batteries to recycle that too (batteries are basically a very rich lithium ore), can’t we do that in clean-powered factories?

    Basically, I think the conversation on “how much manufacturing a given product pollutes” is entirely focused on the wrong thing…

    Also, a lot of these studies compare an EV’s complete lifecycle with just the tailpipe emissions of an ICEV. Mining, refining and transporting gasoline has a huge carbon impact before you even put it in the car.





  • You vastly overestimate that. It’s not a fixed number of cycles, it’s a number before significant degradation. In other words, after you’ve spent ~8000 hours driving, you’ll have to recharge about 40 minutes earlier.

    If you think your ICE car is still top shape after that long, go ahead man… But in all likelihood, it’s burning a little oil, it’s not as quick as it used to be, the transmission has a weird clunk in third, etc… nothing mechanical works forever, and yes that includes hydrogen.

    Hydrogen, by the way, is the worst of both worlds… It solves a very minor issue (charging on road trips) while introducing a whole lot of new ones. The infrastructure for it is non-existent, it’s still a lot of mechanical parts (if you’re talking about the ICE version) or pretty niche technology (if you’re talking about fuel cells), it’s a nightmare to store, and it’s probably still produced from fossil fuels.

    There’s a reason BEVs have caught on, and hydrogen hasn’t.

    In short, Ukraine allowed itself to be instrumentalized by the west as a weapon against Russia.

    Pretty sure Ukrainians just want better living conditions just like anyone else. And “the west” happens to have arguably the best living conditions; I’m not surprised anyone would want to be at this table. Are you really arguing that people are looking at Russia as a nice place to go live? I’ve never actually set foot there, but from the other side of the world it doesn’t look good. Even I know it’s not actually “liberalized”.

    Also, invading Ukraine as a preventative measure against NATO expansion turned out to be spectacularly stupid, because it directly led to NATO expansion to a direct neighbour (Finland).

    But yeah, in general I’m not on the side of countries invading other ones. What Russia is doing in Ukraine is wrong, what Israel is doing in Palestine is wrong, and what the US is doing in Venezuela/Iran/Greenland/Cuba is also wrong.

    I kinda doubt the genuineness of the question given the comment about telemetry… I’ll be the first to admit that these things are a privacy nightmare, but that’s a problem with ALL modern cars, not just EVs. It just so happens that most EVs are modern cars, but they’re not necessarily worse than your random off-the-shelf 2026 Nissan Rogue.

    Still, genuine answer: Haven’t done that many roadtrips where I’ve needed to charge more than once, actually. But my car can easily leave now and go 2-3 hours at highway speed without stopping. Make that 3-4 hours if I set it to charge at 100% the night before (in case of a planned roadtrip), as I usually only charge it to 80% to preserve battery life. Not sure how many miles that is as I’m to lazy to do the conversion, but this is why I use “hours at highway speed” as a metric.

    A good resource to look at the various scenarios specific to your situation / area would be ABRP.
