You seem to have a good grasp of creating high level models.

I always see people referring to the energy consumption of bitcoin as though it’s strictly additive.

What I’d be interested to know is how it compares relative to energy costs for transacting with and securing fiat currencies.

Second, what people tend to ignore is that innovation doesn’t come in a vacuum - there are second, and third degree improvements triggered from it. In a world where bitcoin is $1million, it means the world has agreed on the benefits, and we will see innovations to address the tradeoffs that come from this. For example, we could see significant investment into renewable energy as a means to support the energy consumption of bitcoin.

Third, and this isn’t directed at you, just a general statement based on arguments I see on HN - cryptocurrency itself does not have high energy consumption. Proof-of-work mining does. There are methods to support cryptocurrency that do not result in high energy consumption (Proof of Stake, DAGs). It’s wrong to generalize energy consumption issues to all cryptocurrencies.
