A study by the University of Munich reveals that Bitcoin mining requires significant computing power, leading to carbon emissions comparable to major cities like Las Vegas. The process involves solving complex mathematical problems, consuming large amounts of electricity. As of November 2018, Bitcoin mining used about 46 terawatt hours of energy, equivalent to over 5.6 million tons of coal. The study found that 68% of mining occurs in Asia, 17% in Europe, and 15% in North America, generating over 22 million tons of carbon emissions annually, similar to emissions from countries like Sri Lanka or cities like Vienna.
