Bitcoin Energy Consumption Index

That linked article makes very interesting reading - I knew bitcoin gobbled up energy, but I did not realise it was the equivalent of a country like Denmark!

There’s a comment on PoS: “More energy efficient algorithms, like proof-of-stake, have been in development over recent years … energy consumption of proof-of-stake is negligible compared to proof-of-work. Bitcoin could potentially switch to such an consensus algorithm, which would significantly improve sustainability. The only downside is that there are many different versions of proof-of-stake, and none of these have fully proven themselves yet. Nevertheless the work on these algorithms offers good hope for the future”.

Is it feasible that Bitcoin could switch to proof-of-stake? That would present a challenge to Peercoin

And how does a proof-of-stake coin/blockchain ultimately “prove itself”?
