The rapid advancement of artificial intelligence (AI) technology has brought forth a pressing concern regarding the energy consumption associated with large AI modelsThese complex and data-hungry creations have transformed from simple algorithms to powerful players in various industries, yet their insatiable appetite for energy has raised questions about sustainability and the long-term viability of AI development.

AI models, particularly those in natural language processing, are notorious for their energy consumptionFor instance, according to the 2023 AI Index Report from the Stanford Institute for Human-Centered AI, training the AI language model GPT-3 required an astonishing 1287 megawatt-hours of electricityTo put this into perspective, that amount of energy is equivalent to what it would take to power about 3,000 Tesla electric vehicles over a distance of 200,000 miles each

Furthermore, this training process produced an estimated 552 tons of carbon dioxide emissions—an alarming figure that underscores the environmental implications of such technology.

To appreciate the energy demands of AI models, it's crucial to compare them with more familiar activitiesResearch reveals that a standard Google search consumes approximately 0.3 watt-hours of power, while a single query processed by the AI model ChatGPT uses about 2.96 watt-hoursRemarkably, a Google search powered by AI can consume up to 8.9 watt-hoursThe numbers continue to climb when we consider water usage, particularly during the development and training phasesThe GPT-3 model requires close to 700 tons of water over its training period, with a consumption of roughly 500 milliliters per every 20 to 50 responses generated.

The ramifications of increasing energy and water consumption extend beyond the initial training of models

As the next generation, GPT-4, is set to be 20 times larger than GPT-3 in parameter size and 10 times in computational power, its energy usage is expected to rise sharply, escalating concerns regarding the overall sustainability of AI technologies.

Looking forward, a research report by Huatai Securities anticipates that data center electricity consumption in China and the United States will dramatically increase by 2030, potentially reaching between 0.65 to 0.95 trillion kilowatt-hours and 1.2 to 1.7 trillion kilowatt-hours respectively, indicating growth rates of 3.5 to 6 times the figures recorded in 2022. Such increases suggest that AI-related energy consumption could account for up to 31% of total electricity usage in these countriesThe crucial question is, why are these AI models so demanding in terms of energy? The rapid technological advancements have spiked the demand for high-performance chips, which in turn has significantly elevated electricity consumption.

Moreover, the need for powerful computational resources means that data centers operate continuously, generating substantial heat that necessitates complex cooling mechanisms

Statistics indicate that about 60% of the operational costs of data centers arise from electricity bills, a significant portion of which is primarily incurred for cooling solutionsIn fact, a staggering 60% of a cooling-focused data center's electricity is dedicated to maintaining ideal temperature levels, leaving less than 40% for the actual processing tasksOver the past decade, the energy consumption of data centers has surged nearly tenfold, signaling an unsustainable trend.

Despite these challenges, leaders in the tech industry, such as NVIDIA's CEO Jensen Huang, remain optimistic about the future of AI, asserting that while AI systems are energy-intensive, the rapid advancement in computer performance could lead to more energy-efficient calculationsIn China, strict energy consumption regulations could mitigate some of the impacts as industries are prompted to improve energy efficiency metrics.

As renewable energy gains traction and China's energy policies shift from addressing consumption limits to focusing on carbon emissions, the case for sustainable AI development can be strengthened considerablyThe country possesses unique advantages in resources for developing AI while simultaneously addressing energy sustainability.

To successfully navigate these energy challenges, experts suggest proactive planningForecasts indicate that by 2025, AI-related functions will account for 10% of total energy use in global data centers, up from just 2% todayThis brings the need for strategic infrastructure developments into sharp focus, emphasizing the importance of adequate water supply and electrical resources to sustain burgeoning AI operations.

Recognizing the intricate connection between future AI developments and energy storage, stakeholders are encouraged to look beyond mere processing power

OpenAI's co-founder Sam Altman posits that significant advancements in AI technology may hinge on breakthroughs in clean energy—particularly in nuclear fusion and more affordable solar energy technologies, as well as enhanced battery storage capabilitiesThese factors are integral to ensuring the steady progress of artificial intelligence.

Companies have begun exploring innovative cooling solutions to offset the extensive energy and water needs of data centersMicrosoft has experimented with underwater data centers, while Facebook strategically placed its facilities near the Arctic CircleSimilarly, Alibaba Cloud turned to utilizing deep lake water for cooling at its Qiandao Lake data centerFurthermore, many companies have opted to establish data centers in regions rich in hydropower resources, allowing them to leverage natural advantages.

Currently, a multifaceted approach involving algorithm optimization, the design of more efficient AI-specific hardware, and refining the training processes of neural networks may significantly lower energy usage in large AI models

Utilizing innovative cooling methods such as natural cooling, liquid cooling, trigeneration systems, and waste heat recovery can also enhance energy efficiency within data centersFrom a technological standpoint, the emergence of photonic intelligent chips presents new possibilities for addressing the pressing issues of energy and water use associated with AI advancements.

As the development of large AI models progresses, it becomes imperative that these advancements adhere not only to standards of sophistication and intelligence but also fulfill criteria for sustainability and ecological consciousnessThus, it is crucial for both national and local governments to consider integrating the data center sector into a high-energy consumption management framework while ensuring proper strategic planning is in placeConsolidating resources and enhancing the effective use of AI models will help mitigate the impact on power and water resources
