According to a study by the analytical company CoinShares, in 2021, bitcoin miners generated 42 million tons of CO2, which is 0.08% of the total amount of carbon dioxide emitted into the atmosphere.
A report published on the company’s website states that in 2021, bitcoin miners generated 42 million tons of CO2. Considering that 49,360 million tons of carbon dioxide were emitted into the Earth’s atmosphere in just a year, bitcoin miners generated 0.08% of CO2. Note that the researchers took into account the efficiency of devices, the hashrate of the network of the first cryptocurrency and energy consumption. Therefore, the actual CO2 emissions of bitcoin miners may vary slightly.
Analysts also reported that Bitcoin miners consumed 89 TWh in a year, which is significantly less than the University of Cambridge analysts estimated.
According to CoinShares, miners in Russia consume 268 MW of electricity, while mining farms in Kazakhstan consume 787 MW. The United States is the leader in energy consumption by miners, where 1,380 MW are spent on farms. CoinShares analysts estimate the number of working devices at 5.9 million units.
Earlier, the American rating agency Fitch Rating reported that mining companies may pose risks to the stability of energy supply in the United States.
