   "The physical money we use today requires a total of 11 terawatt-hours
   per year to produce. Gold mining, another very labor-intensive process,
   requires as much as 132 terawatt-hours. These numbers make Bitcoin and
   its 8.27 terawatt-hours look like a science fair project."

   Not if the point is a dead planet.
   That's ALL I care about. Cars, which you mention, are another much
   thornier issue because they've been made a social necessity and that
   will take time to undo. As with another not often acknowledged source
   of carbon based pollution due to humans... The factories that make damn
   near everything consumer industrial societies have.
   But unlike those things, bitcoin generates huge amounts of pollution
   due to its electric demands, and, bluntly, it isn't necessary in any
   way shape or form.
