I have been having a bit of an argument with some anti-EV types who claim that the mineral/metal resource constraints of the earth would never allow for enough batteries and solar panels to have a true EV/Solar world.
Since I know there are a lot of people smarter than me here on the forum I thought maybe someone could answer this question?
I have heard that in terms of the batteries it is only Cobalt that is really even remotely scarce. Panasonic has reduced the amount of Cobalt in its batteries by 75% in the last three years as well.
I guess if we included all the resources required for batteries needed for off-grid storage, EV's, and solar panels for roughly every home and vehicle in the world would be a start...I know its a lot to ask but can anyone come up with some rough numbers?
I think we should also remember that unlike fossil fuels the metals/minerals used here can be recycled for use in future technologies...whereas when you burn oil/gas it is gone forever.
If Tesla and SolarCity actually have this vision in mind for the planet I guess we should know if we have the resources in the earth to do it.
Hope someone out there can help!
