Eric Holthaus writes for Grist:
Bitcoin’s energy footprint has more than doubled since Grist first wrote about it six months ago. It’s expected to double again by the end of the year... And if that happens, Bitcoin would be gobbling up 0.5 percent of the world’s electricity, about as much as the Netherlands.
I can't be the only one paying attention to Bitcoin's rise in energy usage...
That’s a troubling trajectory, especially for a world that should be working overtime to root out energy waste and fight climate change. By late next year, Bitcoin could be consuming more electricity than all the world’s solar panels currently produce — about 1.8 percent of global electricity... That would effectively erase decades of progress on renewable energy.
