Researchers behind the well-known Cambridge Bitcoin Electricity Consumption Index (CBECI) have officially revised its methodology to enhance the accuracy and reliability of the Index’s estimates for the first time since its inception in 2019.
The CBECI was launched in July 2019 in an effort to provide reliable data-driven insights to questions about Bitcoin mining’s energy-intensive nature and associated environmental impact.
CBECI looked at U.S. import records on Bitcoin mining equipment (left) and estimated computing power derived from import data (right). Researchers used the hash rate (in TH/s) and gross weight stated by the manufacturer and applied an equally weighted mix of the following models from Canaan’s Avalon A1246, Avalon A1266, Avalon A1346 and Avalon A1366
