This Asia Times article is dramatically titled The Renewable Energy Transition is Failing. This seems overly dramatic to me, but the point to me is that if we overcome one limit, in this case the atmospheric sink for carbon dioxide, we will encounter other limits. In this article, the author focuses on availability of raw materials like metals. If we overcome that limit, we may have an issue of sinks for these metals and other waste products produced. So we bounce back and forth between sources and sinks being the limiting factor.
