The cryptocurrency mining industry has faced numerous challenges, but debates around energy consumption remain contentious. During a 2023 World Economic Forum fireside chat in Davos, Hut 8 CEO Jaime Leverton highlighted how Bitcoin miners are leveraging wasted energy to drive innovation. She emphasized that miners increasingly utilize abandoned methane, landfills, and flare gas for power generation.
A key advantage of these operations is their ability to operate off-grid, directly at energy waste sources. Leverton, a founding member of the Bitcoin Mining Council (BMC), noted that over 50% of Bitcoin mining now relies on renewable energy.
Crypto Advocates Assert Bitcoin’s Sustainable Energy Use Exceeds 50%
Sustainability expert David Batten recently demonstrated that Bitcoin’s sustainable energy mix has grown annually by 6.2% since mid-2020. China’s 2021 mining ban accelerated this shift, though Cambridge Centre for Alternative Finance (CCAF) data revealed that 20% of Bitcoin’s hash rate during 2021–2022 originated from clandestine Chinese operations.
A September 2022 CCAF study indicated Bitcoin’s emissions intensity is rising, with 62% of its energy derived from fossil fuels—a claim Batten disputes. He argues emissions have declined over 3.5 years, contrasting Bitcoin’s unique ability to reduce emissions as market capitalization grows. Batten estimates sustainable mining at 52.6%, aligning closely with BMC’s 58.9% figure.
Signs of Recovery Amid Adversity
Leverton reflected on North America’s peak of 40 publicly listed Bitcoin mining firms, acknowledging significant market consolidation. She remains optimistic about industry resilience, citing diversification strategies and reduced leverage among surviving operators.
Sabre56 Secures $35 Million to Expand Hosting Sites
Digital asset consultancy Sabre56 announced $35 million in private funding this week to develop a 150 MW hosting facility. Initial phases include sites in Wyoming and Texas, totaling 115 MW capacity. CEO Phil Harvey confirmed competitive power rates ($0.068–$0.072/kWh) under flexible contracts, with plans to add 150 MW annually through 2027.

Luxor Mining Capitalizes on Ordinals Trend
Luxor Mining acquired OrdinalHub, betting on Bitcoin-based NFTs (Ordinals) as a nascent use case. Despite community polarization, Luxor sees strategic value in early adoption. The firm also partnered with Thailand’s Cryptodrilling to penetrate Southeast Asia’s mining market, integrating its hashOS.app platform with Luxor’s technology.
Earlier this month, Luxor launched a miner marketplace to enhance secondary market liquidity via a request-for-quote (RFQ) system—a response to increased equipment inventory during bear markets.
Hive Blockchain Posts Q4 Profit Despite $4 Million Net Loss
Hive Blockchain reported $14.3 million revenue with $3.6 million gross mining margin (25% of crypto-mining income), down from 67% year-over-year due to falling asset prices. The firm mined 787 BTC (+13% YoY) while pivoting GPUs to Hive Performance Cloud (HPC) services, yielding 25x traditional mining profits. CEO Aydin Kilic highlighted HPC’s potential for tenfold growth.
Montana Joins Pro-Mining U.S. States
Montana’s Senate passed a bill safeguarding home miners from utility discrimination, mirroring efforts in Mississippi and Missouri. Sponsored by legislators backed by the Satoshi Action Fund, the bill also proposes tax exemptions for crypto payments.
Kazakhstan Tightens Rules Amid Grid Strain
Kazakhstan introduced laws restricting mining to surplus grid periods, exempting private/renewable-powered operations. Miners must sell 50–75% of holdings through registered exchanges by 2025, reflecting state efforts to balance industry growth with energy stability.
