And where does the lithium for all those batteries come from > Brazil and China. What do we do with worn out batteries? Scrap them because they cannot be reclaimed. Where will all this scrap go, and how long wtll the batteries last in all these electric vehicles, and houses and municipal grid storage centres? Abour 10 years then we are going to be back to rubbing sticks and using tinder boxes (no gas lighters or petrol lighters or tallow candles -- and no fireplaces in modern houses).
