Assuming the share of global activity in the United States remains approximately 38%, we estimate electricity usage from Bitcoin mining based in the United States to range from 25 TWh to 91 TWh. That estimate represents 0.6% to 2.3% of all United States electricity demand in 2023, which was 3,900 TWh.13 This estimate of U.S. electricity demand supporting cryptocurrency mining would equal annual demand ranging from more than three million to more than six million homes.14 The low end of the range would equal annual electricity usage for entire states such as Utah and West Virginia, among others.15 Note that the CBECI-based estimates provided here are only based on Bitcoin and do not include other proof of work cryptocurrencies.
