Bloomberg Analyst: Bitcoin Mining Emissions Decline
Bloomberg analyst Jamie Coutts argues that carbon dioxide equivalent emissions from Bitcoin mining have declined by 37.5% since peaking in mid-2021. This decline is attributed to the China ban, which drove miners to switch to renewable energy sources. Coutts challenges the narrative that Bitcoin burdens decarbonization efforts, suggesting that it can actually accelerate the transition to renewables. The energy consumption of mining machines, often criticized for its environmental impact, has been revised downward by the Cambridge Centre for Alternative Finance. Additionally, including off-grid power sources and miners’ shift to off-grid sources reveals that carbon emissions have only risen by 6.9% despite a 400% increase in Bitcoin’s hashrate since 2019.
Climate-Tech VC Questions Bitcoin’s Contribution to Fossil Fuels
Critics of Bitcoin often highlight its excessive energy consumption and contribution to fossil fuels. However, WattTime, an organization favored by climate experts for accurate analysis, can determine the reliance of miners on fossil fuels. An analysis of Bitcoin miner Applied Digital found that it used fossil fuels 90% of the time and accounted for approximately 54% of all power generated. While climate experts emphasize this data, industry players prefer to focus on the mix of power sources used by miners. Miners also play a role in incentivizing the development of renewable energy plants.
Hot Take: Bitcoin Mining Emissions Overstated?
Contrary to popular belief, recent analysis suggests that concerns about Bitcoin’s carbon footprint may be overstated. Carbon dioxide equivalent emissions from mining have actually decreased by 37.5% since China banned mining in 2021. Furthermore, the shift to renewable energy sources and inclusion of off-grid power sources have resulted in a modest increase of only 6.9% in carbon emissions despite a significant increase in Bitcoin’s hashrate. This indicates that Bitcoin mining can potentially contribute to international decarbonization efforts by accelerating the adoption of renewable energy. While the energy consumption of mining machines remains a concern, efforts are being made to transition to more sustainable practices.
