But in Bitcoin's case it's the same, even the article mentions that "doing today’s calculations would “consume way more power than is generated on the entire planet” if it were done using the CPUs available when Bitcoin launched in 2009.". Energy used when mining Bitcoin could also be considered incidental, the goal is to calculate hashes.

And for all the question there is the same, simple answer - which 'deadmetheny provided in a sibling comment. In all those examples, energy use is incidental. It's an upkeep you want to reduce, and there's money to be made reducing it. In Bitcoin, however, wasting energy is a feature, an integral part of the system.
