Here is one article I rely on with regard to mining: https://bfrandall.substack.com/p/copper

One take away: The good and easy to reach sites are already exploited; ore deposits dwindle worldwide, are harder to reach and of lesser quality. That is, need more, not less energy to find, mine, extract, process.

On the supply chain for PV, e.g.: https://www.theverge.com/22785274/clean-renewable-energy-supply-chain-crisis-climate-mining-manufacturing

To manage decarbonisation we need working supply chains. Which we don't have (pandemics, wars). Beside electricity production (mining, processing, building) and electricity trading (spot markets, subsidies, offsetting) there is the aspect (or: problem) of electricty distribution (network and grid expansions, transport). There is no reasonable time, money, qualified personnel to achieve that in the coming 20-30 years. Which leads me to keep the #infrastructure as is, refurbish and adapt it to more electricity interchange between players on the basis of current power plant technology (nuclear being my favourite). But that only as a side note.
