@dec23k @doctormo @Kiloku Aluminium is mostly used for high voltage lines though, and with solar + battery there is no need for that. I don't think we have a battery that uses aluminium. Also the mining needs oil. I'm not going to argue for all my arguments, but I have looked into this for a long time and the outlook is looking very grim because lack of energy leads to war even if that war must be limited since there is no energy to wage it. Good luck out there, with or without solar panels!

@TechConnectify So a few clarifications nobody will ever read: 1. Hydrocarbons are dead trees which are renewed but very slowly. The tree is the best solar panel with integrated battery. Just takes say 100.000 years to renew. 2. You cannot replace organic energy with metal energy, because you cannot create metal from scratch without coal, oil and gas; and recycling it is only partly a solution. 3. Nuclear (and fusion) is just boiling the planet with atoms instead. 4. The real problem is food.
