Regarding EV, is the main battery running out after 10 years truly a concern?

It's less about the age and more about the miles and battery charge cycles associated with that.

Real-world data (for Teslas at least) shows that the batteries tend to retain 90% of their capacity after ~200k miles. If that amount of reduced range isn't a problem for your usage, you can just keep driving it probably out to half a million miles or more.

Also I would expect these "spent" EV batteries to still hold a lot of value to be repurposed into a second life as home energy storage. They can also have value to recycling plants, which I would expect to start popping up soon. The cost of a replacement battery can be offset somewhat is what I'm suggesting.



Edit: So this brings up an interesting topic (to me at least). Once this first wave of EV batteries starts getting swapped out in quantity, we're going to have a shitload of battery packs that still have ~70% of their original capacity. Maybe that's not good enough in a car, but it's still a nice chunk of energy. If you can pick up an old pack for a couple thousand dollars and have it wired up on your house, even if you don't have solar panels that's a good way to insulate your entire home from power surges/failures/brownouts or to serve as backup power in place of or in combination with a generator.
