Bitcoin Is Greener Than Its Critics Think

``... it's important to put things in perspective. A recent report suggests that at current prices, Bitcoin miners will consume an estimated 8.27 terawatt-hours per year. That might sound like a lot, but it's actually less than an eighth of what U.S. data centers use, 1 and only about 0.21 percent of total U.S. consumption. It also compares favorably to the currencies and commodities that bitcoin could help replace: Global production of cash and coins consumes an estimated 11 terawatt-hours per year, while gold mining burns the equivalent of 132 terawatt-hours. And that doesn't include armored trucks, bank vaults, security systems and such. So in the right context, bitcoin is positively green.''
