This century is going to be powered by an element which is relatevly aboundant, but not so easy to find anywhere, I mean lithium. 

Bolivia and Chile have the largest terrains with lithium high concentration, and with the rising search of materials to make bateries for our cellphones, laptops, and the new and growing electric car market, lithium have became the new white gold in these recent years.

I think that it's also important for us to learn how to recycle this element, because as we already know there's no infinite element in this planet, specially minerals.
