My mistake. In the past when I’ve seen that set of points (and I see them with some frequency) they’re talking points repeated by people not interested in discourse and it’s proven to be a waste of time to go to the effort of rebutting them with facts or argumentation. I’m glad to find I’m wrong in this case.
OK, let us summarize the claims of the paragraph in question and take them one by one:
- EVs have 10 year lifespan vs. 20 years for ICE.
The onus is not on me to disprove this, but on you to prove it. Modern EVs haven’t even been on the road for >= 10 years, so there’s no worked example, and it’s hard to prove a negative. That said, there are a decent number of Teslas that have been on the road since 2012. There are also quite high-mileage Teslas, that have put ~200,000 miles (heh, kilometer fans can convert for themselves, or furlongs, light years, whatever) into the pack. This story reports a pack being replaced for reasons unrelated to capacity. After about 200,000 miles it had lost 6% of capacity.
Anyway, this goes to say that with modern temperature-controlled batteries and battery management systems the shibboleth that batteries will wither and die quickly is at best, not strongly supported by evidence. I will add that these batteries are replaceable. They’re not cheap, but they are replaceable. When an ICE vehicle reaches middle age, by that time it will have required a good amount of money in service, and will require progressively more expensive services as bigger-ticket items start to need replacement. In the case of an EV there’s essentially one big-ticket drivetrain item in this category: the battery. Furthermore, batteries are likely to be substantially cheaper by the time the service life of currently in-service packs is reached, so you can view the current expensive replacement cost to be an upper bound, not an expected value.
If you meant something other than battery life by the claim about “10 years”, please be more specific.
- It’s not like nickel and lithium mining are super great for the environment either.
This is a strawman, nobody says they’re super great for the environment. If I put words in your mouth and rewrite your objection as “the carbon impact of EV manufacture is greater than that of ICE manufacture” that is true, but per the Union of Concerned Scientists, that handicap is completely overcome within 18 months and the EV is better from then on. I’ll also point out that lithium is valuable enough that the simple economics of it mean that batteries will be recycled, not for noble reasons but because money.
If I’ve misconstrued your point, please articulate it more clearly.
- Power from natural gas, not reducing anything, just shifting production.
I think you have conceded this point, correctly pointing out that carbon attributable to EVs is <= half that to ICEs. I’ll just add that it’s also desirable to move particulates and other emissions out of city streets and to a central, scrubbed, inspected plant.
