Consuming immense amounts of energy is actually somewhat counterproductive if we consider the vision of Bitcoin giving us tools for independence. And it's somewhat unethical because we should not be using more than we need on this earth.
However, we don't really know how much energy it is consuming at this stage, so this could just be another reporter trying to find a story.
As time goes buy, I really accept that I am to consume portion of my income for bitcoin. I pay internet bill, but I guess it is small enough to what I receive and of course energy for charging my devices. But then it is not a huge factor after all compared to what I usually have.
