With the rise in global warming and eventual premiums to keep using dirty energy, prices for electricity will most likely skyrocket in the coming decades, and with it, sustainability of Proof of Work chains.

While I agree that PoW has serious issues and limitations in terms of sustainability, it provides strong incentives to secure L1 and have been tested more heavily than PoS systems. I am not convinced that PoW will be completely replaced by PoS alone. Hybrid stacks are more likely

Proof of Work systems currently in place will continue for the foreseeable future, and electricity will become more available and inexpensive in the future.
