I have a 12 year old electric car with an old battery chemistry known for it's fast degradation compared to current chemistries. It still has more than 50% of its original capacity, which is still more than we need.

I wouldn't be surprised if I can keep driving it for another 5-10 years before selling the battery for grid storage.

Faced a loose Pitbull when walking the streets on my own. It wasn't until then that I realised a dog is completely capable of killing me and there would be nothing I could do to stop it.

Fortunately, it turned out to be quite friendly, and the owners came looking for it a few minutes later.

You might be right on this one. I'm not able to find a source to dispute that.

In other news, some Chinese car manufacturers are releasing cars with sodium ion batteries late this year / early next year. Lithium might not be a bottleneck for EV production.

I still agree with your initial point. More public transport is needed.

"The U.S. Geological Survey produced a reserves estimate of lithium in early 2015, concluding that the world has enough known reserves for about 365 years of current global production of about 37,000 tons per year"

"With known lithium “resources” at 39.5 million tons, we get about 50 years of supply with 100 Gigafactories"

There is a lot more lithium in the world, particularly in solution in the ocean, that is not currently listed in resource estimates. As lithium demands increase, more of these sources will be utilised.

Not true. There is more than enough lithium in the world for every person to have an EV. This is not even accounting for new battery chemistries like sodium ion that don't use lithium.

I still want more public transport though. Trains are remarkably easy to electrify and don't need batteries.

Put the address in last. You can't accidentally send an unfinished email if there is no-one to send it to.

Interesting. From Nissan:
"The recommended service interval of the factory-fill coolant is 200 000km (125 000 miles) or 15 years, whichever comes first. Subsequent replacement ... should occur every 80 000km (48 000 miles) or 4 years, whichever comes first."

I guess I'll put that on my calendar.

It's a Nissan Leaf, generally known for it's battery overheating issues.

I also have the refreshed model of the Leaf. It has a higher density battery pack with more tightly spaced cells and still no battery cooling. It will overheat if driven more than 600km (400mi) in one day. When hot, the rapid charging speed drops to about 20kW.

Interesting. I guess my 2011 Nissan Leaf would be an outlier then. It's lost some range, but I think it will keep working for me for at least another 10 years.

What's your definition of consumable?

I would have thoughy that recycling almost 100% of a battery into new batteries would be considered renewable.

I'm fairly certain my car doesn't have a coolant system, but thanks for the reminder. I often forget these sorts of things.
