Re: If only battery production was green...
Agreed. Lithium ion batteries are nice in small scale (phones, laptops etc) but the qty of material needed to cover all the proposed EVs and grid storage required to 'green the grid' is horrific. No doubt mostly sourced from China and other countries with lax or zero environmental and worker protection.
Trains could work with alternative technologies such as redux flow or sodium ion as the energy density issue is less of a problem.
