ESG Hound, I'm enjoying your substack a lot, albeit with some delay. Looking forward to part 2 and 3 of this series.

Now allow me to play devil's advocate:

- Germany does not use / need that much of AC: it never gets that hot there, so that solar energy will rather be needed elsewhere

- I would be curious to see a more recent graph of these prices ...

- In the long run, is an 'energy source' really "renewable" if it needs /rare earth materials/ ? I mean, by the time we've mined the economical part of it, we won't be able to use that 'energy source', are we ? how renewable was it then?

- "Battery" could simply be alpine dams (and pumping up), but this is not without environmental consequences...

- if Bitcoin or crypto is about an 'international payment network', then that could be the 'value' of it, as opposed to current speculation / ponzi stuff ... But I have yet to see the compelling numbers for crypto as 'international payment network'

- at the end of the day, I fully agree with you that crypto's energy and computation power gluttony could definitely be used better, even ESG-wise - medical research ? environmental research ? you name it ...
