In an article published on November 7 by Nature magazine, researchers at the Oak Ridge Institute in Cincinnati, Ohio, noted that Bitcoin mining consumes more than three times more energy than gold mining.
According to the Oak Ridge Institute report: "From the beginning of 2016 to the middle of the same year, the energy required for Bitcoin mining was: 1 US dollar to 17 megajoules. At the same time, the energy required for gold mining of equivalent value in dollars was 5 megajoules."
According to the report, other cryptocurrencies, such as Litecoin, Ethereum and Monero, also required more energy for mining than gold with equivalent value.
The only metal whose extraction process consumed more energy than the equivalent dollar value of Bitcoin was aluminum, which required 122 megajoules for rare earth oxides (REOs), for which 9 megajoules were required.
