Yes, in a couple years there will be more electric cars, but solar power installations are getting less expensive every year. I don't know how long until there are enough electric cars to need "Germany-sized" solar installations, but when they do they'll pay a lot less than Germany did. I don't think Elon Musk would green-light the "100% solar power" line without doing the math. Again: you can argue about whether he's lying, but I can guarantee you he knew exactly the scale of what he was promising. That makes it all the more impressive, imo. Re:lying, I'm imagining at some point they'll transition over to "we buy 100% solar power for SuperChargers", which is fine by me since it's functionally equivalent to what they're doing now.
