This video details the required materials needed to complete the transition from fossil fuels to the “green economy”. It’s basically an engineering feasibility study. It’s reasonably thorough, a little over an hour. The presenter is a PhD in mining engineering.
The quantity of metal required to make just one generation of renewable tech units to replace fossil fuels, is much larger than first thought. Current mining production of these metals is not even close to meeting demand. Current reported mineral reserves are also not enough in size. Most concerning is copper as one of the flagged shortfalls. Exploration for more at required volumes will be difficult, with this seminar addressing these issues.
