Agree with you 110 Terawatt Hours per year is likely too much, even though it's `less alarming than you might think` (quote from the last paragraph of HBR article). Core of the post was not much on the usage of Bitcoin rather than the trend towards decentralisation. Resource usage of proof-of-work based blockchain is definitely a discussion for a later post though.
I also invite you to look at the source for this number (https://cbeci.org/cbeci/comparisons), which is nuanced, and makes the distinction between electricity and energy consumption.
