Those stories were based on [possibly intentional] misunderstandings of how #Bitcoin works.
It absolutely doesn't take a significant amount of energy to transmit a Bitcoin transaction. The one way hashes involved in signing the message are trivial, which is the whole point of a one way hash.
So those stories would be like computing the energy cost of writing a letter by including the energy used to transport the letter by air across the country for some reason.
But heck, those narratives got clicks, so ::shrug::
