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.
Many say bitcoin use too much energy and it is a popular debate that we see going on about the environmental damage that is done due to bitcoin mining and I have heard some miners say bitcoin mining consume more electricity than other currency mining and some even don't mine bitcoin anymore specially in countries like mine where electricity prices are high so there wont be any considerable amount of profits at the end for the investment but hope with better solution this situation will change or this will become a major issue for the environment if majority of the population starts to use bitcoin
