Do you think it is possible to maintain solar/wind for an extended period of time given the reliance on rare earth minerals that it would create? Also one argument that I haven't heard answered is how to handle the non-biodegradable old solar panels/windmills that need to be replaced. These things definitely can be implemented but are they sustainable? Not a rhetorical question, I'd actually like to hear some opinions on this.
