Cambridge Revises Bitcoin Mining Index, Lowers BTC’s Estimated Power Use

Cambridge Centre for Alternative Finance has importantly revised its Bitcoin Electricity Consumption Index, lowering its estimates of the cryptocurrency’s vigor usage aft uncovering its erstwhile exemplary greatly overstated powerfulness consumption.

Cambridge Centre Revises Bitcoin Energy Estimates Downward: Corrected Index Reflects More Accurate Power Consumption

In a report published this week, the probe halfway said its anterior methodology, successful spot since 2019, worked good during periods of debased mining profitability but exhibited “shortcomings” erstwhile profits surged, peculiarly successful 2021. The erstwhile scale arsenic weighted each profitable mining machines successful use, which led to an overrepresentation of older, little businesslike models erstwhile mining was highly lucrative.

“Evidence suggests this bottleneck resulted successful adjacent next-generation hardware being stored successful warehouses owed to a deficiency of abstraction successful information centers,” the study stated. “Given that adjacent caller machines were being stored, it is tenable to infer that mining operators would person already replaced each aged machines with newer models, exploiting each imaginable means to heighten the wide ratio of their mining operations.”

Cambridge said it has present integrated a weighting origin into its calculations to amended relationship for the disproportionate interaction of new, much almighty mining rigs connected Bitcoin’s full computing powerfulness and vigor draw. It besides added a two-month lag betwixt the merchandise and cognition of caller equipment.

The changes chopped Cambridge’s 2021 estimation by 15 TWh, from 104 TWh down to 89 TWh. Its 2022 calculation fell by 9.8 TWh, from 105.3 TWh to 95.5 TWh.

“We are assured astir our estimates and respect each update arsenic a progressive measurement toward enhancing their reliability,” the study stated. “As transparency is simply a cornerstone of our work, we volition showcase however this update has altered past estimates.”

Cambridge noted its scale provides lone a unsmooth approximation of Bitcoin’s existent energy usage owed to the decentralized quality of the network. It said further enhancements to its methodology are needed, on with greater information of mining’s clime risks and opportunities to mitigate these issues.
