Hard to find the original numbers since China, which accounts for ~70% of mining, cracked down in summer of 2021. But according the US Energy Information Administration, crypto mining in 2024 accounted for 0.6% to 2.3% of all US electricity consumption. https://www.eia.gov/todayinenergy/detail.php?id=61364 https://www.eia.gov/todayinenergy/detail.php?id=61364 According to the UN, China's share of mining dropped from 73% in 2020 to 21% in 2022. They also state > The greenhouse gas emissions of Bitcoin mining alone could be sufficient to push global warming beyond the Paris Agreement's goal of holding anthropogenic climate warming below 2 degrees Celsius. https://unu.edu/press-release/un-study-reveals-hidden-environmental-impacts-bitcoin-carbon-not-only-harmful-product https://unu.edu/press-release/un-study-reveals-hidden-enviro... In 2024 the percent of global energy usage for crypto mining has dropped to around 2% according to the IMF https://www.imf.org/en/Blogs/Articles/2024/08/15/carbon-emissions-from-ai-and-crypto-are-surging-and-tax-policy-can-help https://www.imf.org/en/Blogs/Articles/2024/08/15/carbon-emis... Someone less lazy than me could probably take some of these statistics to get an estimate of global energy consumed by crypto mining at its peak in 2020
