At no cost to the tax payer? I keep on reading bail out but I’m inclined to think it’s going to more like a bail in. Depositors transformed into shareholders. I read about these possible type of changes after the last banking crisis.

The negative development in our service business underscores that we have much work ahead of us to stabilize our business and return to profitability," said Siemens Gamesa Chief Executive Jochen Eickholt, who joined from Siemens Energy last year.

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)

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.

Nobody is refuting that there are not alternatives & solutions. Each of the pts are supported. It’s the shear scale of replacing conventional energy & we haven’t really dented its use.

This is from today’s James Kunstler blog:

The solar electric I installed on the house nine years ago is down. It’s supposed to feed that monster called the grid. Since April, I noticed that the electric bill is creeping up way beyond the usual seventeen bucks that the electric company charges home solar producers for the privilege of feeding their system — which, let’s face it, has a downside for them because the intermittency of so-called alt-energy disorders their operations.

This article covers major issues:

Limits to Green Energy Are Becoming Much Clearer: https://ourfiniteworld.com/2022/02/09/limits-to-green-energy...

[1] It is becoming clear that intermittent wind and solar cannot be counted on to provide adequate electricity supply when the electrical distribution system needs them.

2] Adequate storage for electricity is not feasible in any reasonable timeframe. This means that if cold countries are not to “freeze in the dark” during winter, fossil fuel backup is likely to be needed for many years in the future.

3) After many years of subsidies and mandates, today’s green electricity is only a tiny fraction of what is needed to keep our current economy operating.

[4] Even as a percentage of electricity, rather than total energy, renewables still comprised a relatively small share in 2020.

5] Most modelers have not understood that reserve to production ratios greatly overstate the amount of fossil fuels and other minerals that the economy will be able to extract.

6] The world economy seems already to be reaching limits on the extraction of coal and natural gas to be used for balancing electricity provided by intermittent renewables.

7] Conclusion. Modelers and leaders everywhere have had a basic misunderstanding of how the economy operates and what limits we are up against. This misunderstanding has allowed scientists to put together models that are far from the situation we are actually facing.
