Re: sustainable, clean energy
"Neither are solar and wind, because after 20+ years you need to replace the infrastructure. I'd bet the junk this creates has a higher volume than nuclear waste ;)"
20 years is optimistic. Not too far from where I live is a wind area (it's windy right now) with derelict turbines only 10 years old. Once the manufacturer updates their products or loses out to other companies and shuts down, there aren't spare parts to be had to repair existing infrastructure. The new turbines are larger and on bigger pylons so the old ones have to be completely torn down one rusty bolt at a time. I'm not sure if it isn't cheaper to install them over tearing them down. New parts go together much easier and faster than torching a tower structure apart.
