So bitcoin, which still has almost no practical use for anyone in the real world, consumes as much energy as a country with a GDP of $98B and population of $16M.

It used to be that this was acceptable because bitcoin was going to solve our inequality problems and make money more egalitarian and all internet transactions smoother (or something). Yet, with a price of $7K per coin I still struggle to find anyone I know who has ever made a real purchase with it.

So what exactly are we getting from this energy demand? Does there exist a pie chart for where all the miners source their energy and maybe a metric for tons of CO2 per coin/transaction?
