Im very suspicious climate change investments, it sounds nice 'clean energy', but those batteries need lithium, the supply locations are limited and not fully explored, but the worst thing is the 'damage' it does to water sources especially in 'dry regions' as it's very water-intensive to process it. Plus a full global consumption against current reserves need calculating.
The banks shouldn't all rush into climate friendly investment due the lithium factor is well explored and it's impacts to water or if another processing method can be used.
