This makes me think is it even possible to have clean energy.  Maybe its not.  Idk.  I do think of the thing that says "for every reaction there is an equal and opposite reaction" and if that holds true for clean energy... maybe that is a fallacy.<br><br>I honestly don't know  But it does make me wonder if its possible or not.,(reply>), Well Lithium is needed in batteries, the chemical reaction "stores" electricity, that's how we've been doing batteries for a very long time, however much like how Rubber used to be harvested from Rubber trees, science and technology made synthetic rubber more effective, perhaps via nano technology less resources can be used for the same effect but we don't have that technology now and we might never get it, im no expert but from history I can say, science, technology and innovation drives this progress the most.
