Cambridge Bitcoin Energy Consumption Index lowers estimate by 14%, revises methodology

The Cambridge Bitcoin Electricity Consumption Index (CBECI), which tracks global Bitcoin energy consumption, has undergone its first major update since 2019, influenced by evidence pointing to frequent overestimating Bitcoin’s electricity usage.

A new report is said to shed light on the evolution of Bitcoin mining and to clarify the rationale behind the changes in CBECI’s methodology, providing an in-depth analysis of the transition of Bitcoin mining hardware – from CPUs to GPUs, then FPGAs, and finally to the current state-of-the-art ASIC miners.
