Rising crypto adoption had previously led to concerns about their impact on the environment. Bitcoin mining is an energy-intensive process, built upon the Proof of Work mechanism. Crypto mining firms all around the world have been addressing these concerns over the years, and the results are visible. The Bitcoin Mining Council(BMC), in its Q2, 2022 report revealed that 59.50% of the electricity used for BTC mining. It is currently being derived from sustainable sources.
In its latest report, the BMC network revealed worldwide Bitcoin mining industries increased their use of renewable energy by 6% during the second quarter of the previous year(2021), and 2% in the previous year. The total mix ratio reached almost 60% in the previous quarter, placing itself among the top sustainable industries around the world.

BMC in its report also noted a significant increase in operational efficiency, coinciding with the rise in sustainable energy adoption. The mining hash rate for Bitcoins in the second quarter rose 137%, with a 63% increase in energy consumption. This resulted in a 46% increase in the operational efficiency in Bitcoin mining farms. Microstrategy CEO Michael Saylor highlighted a combined 5,814% increase in energy efficiency among crypto miners over a period of 8 years.
In a stark contrast to common perceptions, Bitcoin mining nowadays accounts for a meager 0.09% contribution to global carbon emissions. Estimates suggest global carbon emissions amount to 34.8 billion metric tons at present. Bitcoin mining also consumes a mere 0.15% of the world’s total energy supply.

The BMC reports prove the so-called concerns of crypto detractors are illogical and inaccurate. Saylor notes:
“People have been predicting that Bitcoin was going to use up all the energy in the world for quite a while. That’s not happening and it’s not going to happen because of the efficiency dynamics.”
Fred Thiel, the CEO of Marathon Digital Holdings, acknowledged the merits of increased mining efficiency and how the industry strives to continue the progress, stating:
“The efficiency gains are 100% focused on energy consumption because energy is our key input cost. As energy prices go up, it forces us to become more efficient.”
Analysts believe the surge in Bitcoin valuations has driven the network’s energy efficiency. This is evident from the almost-proportional increase in valuations and efficiency throughout the last 8 years. The increased price drives the valuation of ASIC mining devices upwards, which in turn accelerates device innovation. Devices labeled “efficient” are cost-effective and help in profit optimization. This leads to the extinction of less-efficient devices from the marketplace, contributing to an increase in the overall efficiency of the crypto mining industry.
The BMC report utilizes data from its member organizations, which combine a total of 50.5% of BTC’s mining hash power worldwide. US lawmakers have been expressing interest in the cryptocurrency’s mining consumption across the nation, sending letters to the Department of Energy(DOE) and the Environment Protection Agency(EPA), asking them to enforce requirements on mining organizations to report energy consumption and emissions.
