Bloombergโs Optimistic Take on Bitcoinย (BTC) Miningโs Green Energy Mix
A recent research note from Bloomberg Intelligence analyst Jamie Coutts impliesย that the energy used by the Bitcoinย (BTC) mining industry is now over 50% green. Coutts based this conclusion on data showing a decline in Bitcoinโs carbon emissions since 2021, along with an increase in its hash rate. Nonetheless, industry expert Daniel Batten argues that this claim is only partially correct.
Batten describes that the decline in emissions intensity, which refers to the amount of carbon dioxide emitted per unit of electricity consumed by the Bitcoinย (BTC) network, can be attributed to both a more sustainable energy mix and increased machine efficiency. Other factors contributing to the reduction in coal-powered Bitcoinย (BTC) usage include Chinaโs mining ban, Kazakhstanโs loss of miners, and Marathonโs reduced mining activity in Montana.
Estimating Bitcoinโs Carbon Emissions
Estimating Bitcoinโs carbon emissions and overall power consumption is still an evolving field. Cambridge recently updated its Bitcoinย (BTC) Mining Index to account for the growing efficiency of ASIC machines, resulting in a 14% decrease in Bitcoinโs electricity consumption figures for 2021. Inย addition, off-grid mining poses a challenge for measurement.
Batten attempts to consider off-grid miners in his estimates of Bitcoinโs energy mix and believes that more than 53% of the industry is powered by sustainable sources. He identifies four main factors contributing to the greening of Bitcoinย (BTC): an increase in off-grid renewable miners, miners transitioning to sustainable sources, more mining utilizing the Texas grid, and a decrease in mining activities in Kazakhstan.
Hot Take: The Complexity of Bitcoinโs Green Energy Mix
The debate surrounding Bitcoinย (BTC) miningโs environmental impact continuesย as specialists analyze its energy mix. Althoughย while Bloomberg impliesย that over 50% of the industry uses green energy, industry expert Daniel Batten argues that this claim overlooks the role of increased machine efficiency. Estimating Bitcoinโs carbon emissions remains a developing science, and the presence of off-grid mining further complicates measurements. Nonetheless, Batten outlines the positive contributions of factors such as off-grid renewable miners, transitions to sustainable sources, and shifts in mining locations. As the industry evolves, achieving a truly sustainable energy mix for Bitcoinย (BTC) remains an ongoing challenge.
