    And where do you think all the materials for that come from? Eind turbines, solar panels and batteries require huge amounts of (rare) earth materials that need to be dug up in very -let’s say ugly- mines… lithium for example, is now the core component for most of our batteries and lithium mines are polluting as hell. If we want to have all the lithium we need for all of our storage capacity, well need to destroy beautiful places like the Atacama desert because if we don’t we won’t have enough lithium.

      The rare in ‘rare earth’ is not related to scarcity, many of the most common elements in the crust are ‘rare earth materials’ lithium is a great example because it’s hugely abundant especially in salt water where it can be extracted at the same time as desalination - which is especially good paired with wind and solar because it can rapidly switch power usage so excess energy at peek times can be used which helps stabilise the grid, then when generation is low it can pause to conserve power. Also ideal for placement directly tied to solar where sun and saltwater are plentiful, such as the equator.

      The other good thing is that lithium is infinitely recyclable and battery tech keeps evolving to require less of it in its chemistry. Theres endless other battery technologies and energy storage methods available too, lithium is great for cars and phones because of the energy density but for grid tied storage that’s not really an issue.
