A very compelling case and the material for 100% renewables is staggering. How this can be ignored is bewildering.

A discussion at:

https://www.reddit.com/r/collapse/comments/wuc4vg/assoc_prof...

Simon Michaux presents the deck of data showing details of where his calculations are coming from that show even the first generation of renewables to replace fossil fuels is going to outstrip our capacity to source the minerals (lithium, copper, vanadium, manganese, cobalt, etc required for only the first generation of renewable energy) and the amount of energy to be replaced based on efficiencies is exorbitant. Summary: EROI going down, mineral requirements going way up spell issues moving forward.

Right from the introduction he assumes all EVs will be using Li ion which is already being phased out of everything but top performance luxury vehicles, then goes on to double count the storage asking where one could possibly find a few trillion Wh of batteries. Then blindly asserts that recycling will be impractical when recycling facilities already exist and are fighting over access to dead batteries.

He then bemoans the lack of a better solution which, as the people who have been promoting renewables for half a century have been saying the entire time while the infrastructure was torn down, is trains and ebikes (or just bikes in most areas).

Every single statement is fractally wrong and I'm only a paragraph in.

I’m interested in the new phase out and the realistic time frame. It’s not this: https://www.theverge.com/2022/1/24/22898666/panasonic-4680-t... Currently recycling is very low. I think he’s focused on what’s likely in production for the near future and the real material problem of all infrastructure ( its massive)

I'm hoping we can spend some tax money on real infrastructure rather than handouts for rich people to line elon musk's pockets. A train line, a bike lane and a handful of trolley busses take far less network upgrades than 10,000 luxury cars.

It would also help immensely if we could find our sanity and build some 400kg LEVs and NEVs with a 2kWh battery and a 150cc range extender rather than 2-5t padded ego protectors with 50-100x as much battery.

The bus and bus network of the future is more likely to be built and operated by Elon Musk than any Government agency. Auto-routing, and segregation by socio-economics (based on rider ratings and enforced subscription fees) is the killer feature of a sustainable mass transit system.

So just saying the quiet part out loud now, huh?
