Tackling Environmental Issues? How Bitcoin's Energy Consumers Are Tackling AI's Carbon Footprint
In Brief
Bitcoin miners are contemplating modifications to their operational strategies to align with the growth of AI and offer distinct advantages, despite ongoing criticism regarding their substantial energy consumption.
The constant demand for electricity by AI systems poses risks to power grid stability and undermines climate change mitigation efforts. Bitcoin miners, long criticized for their high energy usage, are identifying chances to adapt their operations in ways that would be beneficial for the AI sector.
A Bitcoin mining company Core Scientific has recently emerged from bankruptcy . With the intention of boasting a 200-megawatt data center infrastructure to accommodate CoreWeave's advanced computing facilities and the energy-intensive GPUs essential for AI model training; this Austin-based company has inked a significant 12-year deal with the AI cloud provider CoreWeave.
Throughout the duration of the original contract, Core Scientific expects that its partnership with CoreWeave alone will generate over $3.5 billion in revenue. Yet, this marks just the start; within the next three to four years, the company plans to convert 500 megawatts of its current Bitcoin mining operation into facilities that will support AI. Core Scientific’s CEO, Adam Sullivan, emphasizes that their objective is to become a leader in the market by providing digital infrastructure designed for high-performance computing.
Following the latest Bitcoin 'halving' event in April, which slashed mining incentives in half, it's estimated that the industry saw a staggering $10 billion drop in annual revenues based on pricing trends at that time.
Alarming Figures for Climate and Sustainability
Microsoft, a major investor in OpenAI, witnessed a 30% increase experienced significant increases in greenhouse gas emissions last year due to its AI ambitions, jeopardizing its pledge to achieve carbon neutrality by 2030 alongside a doubling of its data center footprint.
In a drought-stricken area, one of Microsoft’s new data centers located in Arizona is predicted to utilize over 50 million gallons of drinking water annually. Local communities are also raising objections to the establishment of data centers within residential zones, which are being converted into industrial landscapes to accommodate these facilities.
Delegate from Virginia, Ian Lovejoy, There have been raised concerns regarding the current generation and distribution capability of power utilities, indicating they may fall short of powering the planned data centers. Although it is commonly believed that infrastructure will evolve over time, significant uncertainty endures.
Worries regarding the water usage of data centers are also increasingly being voiced. As per research conducted by UC Riverside, data centers might require over 1 trillion gallons of freshwater for cooling purposes by 2027 due to the surging global demands for AI.
AI researcher Sasha Luccioni mentioned that companies were previously more transparent about their data sources, training durations, hardware specifications, and energy consumption. However, over the past 18 months, there has been a noticeable shift towards greater opacity.

Renewable Energy and Efficient Hardware Revealed
Recently, Nvidia has unveiled new top-tier GPUs boasting an astounding 25-fold enhancement in energy efficiency compared to older models.
While many emerging facilities heavily rely on fossil fuels at their inception, AI corporations also position themselves as advocates for crucial investments in renewable energy sources such as wind, solar, and nuclear, to support their data center expansions. Transparency and environmental guidelines for data centers are beginning to take shape.
Nevertheless, the ecological concerns associated with AI’s energy consumption extend beyond a mere desire for technological solutions. Experts warn that any improvements in efficiency could be negated by the Jevons Paradox Jevon's Paradox, which posits that when a resource becomes more efficient, it leads to an overall increase in consumption due to its relative affordability.
Unlike stationary data centers, crypto mining firms can rapidly adjust their energy demands, providing them with a unique advantage in this energy-intensive field. This flexibility enables Bitcoin miners to engage in 'load balancing' on power grids, aligning their energy consumption with fluctuations in energy supply, especially those stemming from variable renewable sources.
According to the data analytics firm Hashworks, Bitcoin miners can swiftly adjust their energy consumption, creating a real-time responsive mechanism that grid management can utilize to maintain balance. This stabilizing function strengthens the commercial viability of renewable energy projects, which often face challenges due to mismatched supply and demand.

In times of crisis, such as the Texas freeze of 2021 Unique to Bitcoin miners, the ability to dynamically balance load has prevented numerous significant grid failures as they are capable of rapidly powering down to alleviate stress on overloaded systems.
Sensible policymakers are taking notice. Recently, a measure was approved in Oklahoma tax exemption has been established for commercial Bitcoin miners providing flexible load services to power suppliers. Texas is increasingly welcoming cryptocurrency miners operating during off-peak hours to take advantage of surplus wind energy.
Moreover, in regions like Iceland, which boasts abundant geothermal and hydroelectric resources, Bitcoin miners have become essential contributors by maintaining consistent energy demand and generating additional revenue streams that boost the viability and profitability of such projects.
A Harmonious Relationship Between AI and Mining?
While AI data centers lack the ability to quickly scale resources without interrupting user workloads, in theory they could operate in harmony with local, adaptable Bitcoin mining activities. The energy-hungry AI facilities create consumption spikes, yet miners can quickly adjust their intake to mitigate any issues.
Hashworks maintains that Bitcoin mining remains a scalable and economically viable variable load solution. With this new load-balancing framework in place, larger, less flexible AI energy consumers can now leverage it.
Additional synergies exist. The capacity of grid operators to utilize dynamic load balancing becomes essential as they embrace more renewable energy sources. Bitcoin miners are motivated collaborators in the growth of renewables as they seek to discover the most profitable energy sources available.
At the same time, as AI data centers move away from fossil fuel energy sources, they will need vast sustainable alternatives capable of meeting their ambitious expansion requirements. Bitcoin miners can play a supportive role for the grid in this regard.
Of course, merging Bitcoin mining with AI data centers is not a guaranteed path to ecological conservation or a profitable opportunity for cryptocurrency miners.
Significant expenses will arise, and retrofitting outdated mining operations to handle the high-performance AI requirements, which require ultra-reliable power and cooling, won't be feasible for every miner. AI's cooling demands are notably higher due to increased rack density (40 kW/rack for H100s) compared to mining and other computer tasks. as noted by Core Scientific.
According to Jamie McAvity, CEO of Cormint Data Systems, the financial outlay per megawatt for equipping an HPC data center, not including GPUs, could reach as high as $8–10 million, which stands in stark contrast to the $300,000–$800,000 per megawatt needed for Bitcoin mining locations. Furthermore, the total grid stabilization that load balancing can reasonably sustain through Bitcoin mining is not limitless. While mining activities play a role in addressing AI's energy demands, they are not a standalone remedy for the mounting stress on the energy infrastructure, which may necessitate prohibitively expensive capacity enhancements.
