Challenges in Replacing Fossil Fuels with Green Energy: Mineral Shortages and Timelines

Do you know why fossil fuels will never be fully replaced with green energy at the current rate of consumption? It's because there isn't enough minerals available for renewable tech devices, not even for the first generation that is supposed to phase out the old machines. For example, we need 4.5 billion tonnes of copper, while global reserves are less than 0.9 billion tonnes (20% of our needs). The situation is even worse with lithium, as our planet only has 2.3% of what we need.

Even if we had access to the necessary minerals, it's already too late to mine them. It would take approximately 190 years to extract all the necessary copper, and around 10,000 years for lithium.

I am including the data tables in this post, which are from the presentation given by Professor Simon Michaux. I highly recommend watching it here: https://www.youtube.com/watch?v=MBVmnKuBocc

In any case, we can forget about achieving 'net zero.' It simply cannot happen within the timeline we are all supposed to pledge to. This will have numerous and severe consequences, but I will stop here and allow you to contemplate the implications.
