One 2019 study in technology journal Joule concluded that Bitcoin mining produced enough carbon emissions in 2018 to rank its footprint between the countries of Jordan and Sri Lanka. Researchers from MIT and the Technical University of Munich concluded that Bitcoin mining alone accounted for 0.2 percent of global electricity consumption. Add in the effects from other cryptos and electricity usage more than doubled. For example, Bitcoin’s purpose is to send money, enabling the crypto to function as a currency.
