The Cambridge Bitcoin Electricity Consumption Index (CBECI), which tracks planetary Bitcoin vigor consumption, has undergone its archetypal large update since 2019, influenced by grounds pointing to predominant overestimating Bitcoin’s energy usage.
A caller report is said to shed airy connected the improvement of Bitcoin mining and to clarify the rationale down the changes successful CBECI’s methodology, providing an in-depth investigation of the modulation of Bitcoin mining hardware – from CPUs to GPUs, past FPGAs, and yet to the existent state-of-the-art ASIC miners.
Mining ratio evolution.
The CBECI noted that the ratio of ASICs experienced a accelerated surge initially but has since seen a tapering successful maturation arsenic we scope the limitations of semiconductor technology. This slowdown has nonstop implications connected the lifespan of miners, affecting the assumed replacement cycles, with estimates ranging from 1.5 years (academia) to 3-5+ years (industry).
Its methodology has been revised to relationship for this accrued computing powerfulness of newer models, specified arsenic the Antminer S19 XP, which boasts a 140 TH/s capableness compared to the 11.5 TH/s of the 2016 Antminer S9.
CBECI further asserted that the instauration of ASICs triggered an exponential maturation successful Bitcoin’s hashrate, from little than 1 EH/s successful 2010 to implicit 300 EH/s successful aboriginal 2023, revolutionizing mining from a location machine enactment to a nonrecreational endeavor.
Hashrate growth.
While a higher hashrate enhances Bitcoin’s security, it besides escalates mining trouble and the computing powerfulness indispensable to gain artifact rewards. Comprehending these drivers of hashrate maturation was reportedly important to reevaluating the CBECI methodology.
According to the report, investigations into hashrate maturation factors revealed a beardown correlation betwixt the summation successful imported mining hardware to the US and the wide web hashrate growth. Additionally, income information from Canaan Creative indicated that their latest models accounted for astir 45% of their hashrate income successful 2021, suggesting that these much businesslike models apt lend much to hashrate maturation than antecedently assumed by the CBECI methodology.
Upon applying the caller CBECI methodology, the 2021 estimation was importantly reduced by 15 TWh, oregon 14% (from 104 TWh down to 89 TWh), and the 2022 estimation was chopped by 9.8 TWh, oregon 9% (from 105.3 TWh down to 95.5 TWh).

The existent energy usage of Bitcoin continues to beryllium a analyzable issue, with much information required connected the geographic organisation of mining and the sources of energy to physique a implicit picture. The study besides addresses different elements, specified arsenic e-waste and the imaginable for methane mitigation, which power Bitcoin’s biology interaction and request further examination.
The update to the CBECI illustrates their committedness to fine-tuning estimates arsenic caller grounds emerges. This study serves arsenic a stepping chromatic towards a much close and elaborate knowing of the biology implications of Bitcoin mining.
