You started by trying to discredit the work based on the author's work history. Then you threw out a few unspecific attacks on his data sources. Hardly convincing. Essentially name calling. > The absolute most generous interpretation of the report you linked is that it was a mastubatory exercise by a completely naive person who thought he was the first person to think of problems that have been studied for decades Here is a paper published by IEEE this year, On the History and Future of 100% Renewable Energy Systems Research. It is a comprehensive review of the research in this field. https://ieeexplore.ieee.org/document/9837910 https://ieeexplore.ieee.org/document/9837910 Section D. Raw Material Demand for 100% Renewable Energy Systems As the previous criticisms are starting to become less and less tenable, increasing attention is now shifting towards the more salient point of raw materials needed for the transition towards a sustainable energy system. Practically all research in this field finds critical limits for material availability. This may be a major concern and should be addressed with more consideration and analyses to truly test the material limits. Hardly mastubatory, then.
