Limits to green growth?

By 2050 solar panels and wind turbines will require around 12 times as much indium as the entire world produces right now, the analysis predicts. Neodymium production will have to grow by more than seven times, and silver will have to grow by nearly three times. And this is just for renewable energy; all of these metals have other uses in other industries, meaning mining will have to ramp up very quickly.

And, will it be sustainable?
