A key issue for the accomplishment of renewables is power storage because of the impact of wind and solar intermittency, both of which are highly intermittent. Most studies assume gas will be the buffer for intermittency. Other than using fossil fuel such as gas as a buffer, an adequate power storage system to handle intermittency will require 30 times more material than what electric vehicles require with current plans, meaning the scope is much larger than the current paradigm allows.
There are legal things/goals we could try for like reducing current planned obsolesce and enshrine right to repair laws and similar, that would save us on materials and energy in general. Ideally, reducing costs of recycling and becoming more effective at it would be another way to get more metals (might help with the toxic e-dump sites around the world too).
This shows that the whole capitalist growth ideology is fundamentally incompatible with our civilization surviving long term. It’s kind of amazing how all these economists can’t imagine our society running any other way than it is now.
