The environmental impact of artificial intelligence (AI) computing, particularly with regard to water and energy consumption, is an increasingly pressing concern that tech companies may prefer to keep under wraps. Each query made through AI platforms like ChatGPT reportedly demands at least ten times the electricity required for a standard Google search. If generative AI were deployed across all Google searches, it could potentially consume as much electricity as an entire nation, such as Ireland, as calculated by Alex de Vries, founder of Digiconomist, a platform dedicated to highlighting the unforeseen repercussions of digital advancements.
Users of AI applications remain largely unaware of the energy implications associated with their inquiries, as the processing occurs within the expansive data centers maintained by technology firms. According to de Vries, the tremendous surge in energy requirements from AI systems will inevitably lead to increased reliance on fossil fuels like oil, gas, and coal. “Even if AI operations transition to renewable energy, the supply remains limited, forcing a greater consumption of fossil fuels in other sectors,” he warns, predicting that the outcome will be an uptick in carbon emissions.
AI technologies are also significant consumers of water. According to Shaolei Ren, an associate professor at the University of California, Riverside, each session of approximately ten queries on ChatGPT could consume up to 16 ounces of water. The escalating demand for both energy and water has raised alarms across California and beyond. Experts predict that this growing consumption could impede the region’s efforts to shift towards renewable energy sources while simultaneously elevating electric bills for consumers and heightening the risk of power outages.
Experts, including de Vries and Ren, are advocating for increased transparency from technology firms regarding the environmental costs associated with AI usage. Ren suggests that AI companies should inform users about the power and water usage tied to their queries, paralleling the manner in which Google presently displays carbon emissions generated from airline flight searches. “Arming users with this information would enable them to make more educated choices,” he emphasized.
The nature of data centers, which house extensive networks of computer servers to sustain internet functionality, has made them substantial energy consumers. However, the chips designed explicitly for generative AI operations require an even greater amount of electricity, given their capability to sift through vast quantities of data. This specialized hardware generates considerable heat, necessitating additional energy and water to ensure proper cooling.
Despite the undiscovered range of benefits and risks posed by AI, corporations are hastily integrating this technology into existing products. A recent example is Google’s announced implementation of AI-generated Overviews within its search engine. This feature, which presents AI-curated answers at the top of search results, has come under scrutiny for inaccuracies but cannot currently be opted out of by users who wish to minimize their energy and water footprint.
In November, California voters will be presented with the opportunity to determine whether the state will authorize borrowing $10 billion for climate and environmental initiatives. Inquiries to Google regarding its energy expenditures have not been answered, but OpenAI, the creator of ChatGPT, acknowledged the energy-intensive nature of AI. The organization stated, “We are consistently working towards improving our efficiencies and are dedicated to supporting the sustainability goals of our partners.”
Three years prior, Google pledged to achieve net-zero greenhouse gas emissions by 2030; however, its carbon emissions have escalated by 13% in 2023 and increased by 48% since 2019. In their report, Google noted that the integration of AI into their services could complicate efforts to reduce emissions due to rising energy demands. Furthermore, the company’s 2023 data centers consumed a staggering 6.1 billion gallons of water—an increase of 17% from the previous year—indicating a concerning trend.
Ultimately, the technology sector must work toward greater accountability and transparency regarding the energy and water usage associated with AI operations. Without distinguishing the specific demands of AI technologies from other processes, it becomes difficult to ascertain the true environmental cost of incorporating AI into everyday applications. In the opinion of experts, open communication is necessary for consumers to fully grasp and mitigate the environmental impact of their digital inquiries.
In conclusion, the implications of AI on energy and water consumption are substantial, and it is imperative that tech companies adopt a more forthright approach regarding the environmental ramifications of their innovations. Transparency is not merely a recommendation but a necessity as we navigate the complexities of merging technology with ecological sustainability.
