Dubai, UNITED ARAB EMIRATES — A global rush for the next wave of generative artificial intelligence is increasing public scrutiny on an often-overlooked but critically important environmental issue: Big Tech’s expanding water footprint.
Tech giants, including the likes of Microsoft and Alphabet-owned Google, have recently reported a substantial upswing in their water consumption and researchers say one of the main culprits is the race to capitalize on the next wave of AI.
Shaolei Ren, a researcher at the University of California, Riverside, published a study in April investigating the resources needed to run buzzy generative AI models, such as OpenAI’s ChatGPT.
Ren and his colleagues found that ChatGPT gulps 500 milliliters of water (roughly the amount of water in a standard 16-ounce bottle) for every 10 to 50 prompts, depending on when and where the AI model is deployed.
The study’s authors warned that if the growing water footprint of AI models is not sufficiently addressed, the issue could become a major roadblock to the socially responsible and sustainable use of AI in the future.

ChatGPT creator OpenAI, part owned by Microsoft, did not respond to a request to comment on the study’s findings.
“In general, the public is getting more knowledgeable and aware of the water issue and if they learn that the Big Tech’s are taking away their water resources and they are not getting enough water, nobody will like it,” Ren told CNBC via videoconference.
“I think we are going to see more clashes over the water usage in the coming years as well, so this type of risk will have to be taken care of by the companies,” he added.
‘A hidden cost’
Data centers are part of the lifeblood of Big Tech — and a lot of water is required to keep the power-hungry servers cool and running smoothly.
In July, protesters took to the streets of Uruguay’s capital to push back against Google’s plan to build a data center. The proposal sought to use vast quantities of water at a time when the South American country was suffering its worst drought in 74 years.
Google reportedly said at the time the project was still at an exploratory phase and stressed that sustainability remained at the heart of its mission.

In Microsoft’s latest environmental sustainability report, the U.S. tech company disclosed that its global water consumption rose by more than a third from 2021 to 2022, climbing to nearly 1.7 billion gallons.
It means that Microsoft’s annual water use would be enough to fill more than 2,500 Olympic-sized swimming pools.
For Google, meanwhile, total water consumption at its data centers and offices came in at 5.6 billion gallons in 2022, a 21% increase on the year before.
Both companies are working to reduce their water footprint and become “water positive” by the end of the decade, meaning that they aim to replenish more water than they use.
It’s notable, however, that their latest water consumption figures were disclosed before the launch of their own respective ChatGPT competitors. The computing power needed to run Microsoft’s Bing Chat and Google Bard could mean significantly higher levels of water use over the coming months.
“With AI, we’re seeing the classic problem with technology in that you have efficiency gains but then you have rebound effects with more energy and more resources being used,” said Somya Joshi, head of division: global agendas, climate and systems at the Stockholm Environment Institute.
“And when it comes to water, we’re seeing an exponential rise in water use just for supplying cooling to some of the machines that are needed, like heavy computation servers, and large-language models using larger and larger amounts of data,” Joshi told CNBC during the COP28 climate summit in the United Arab Emirates.
“So, on one hand, companies are promising to their customers more efficient models … but this comes with a hidden cost when it comes to energy, carbon and water,” she added.
How are tech firms reducing their water footprint?
A spokesperson for Microsoft told CNBC that the company is investing in research to measure the energy and water use and carbon impact of AI, while working on ways to make large systems more efficient.
“AI will be a powerful tool for advancing sustainability solutions, but we need a plentiful clean energy supply globally to power this new technology, which has increased consumption demands,” a spokesperson for Microsoft told CNBC via email.
“We will continue to monitor our emissions, accelerate progress while increasing our use of clean energy to power datacenters, purchasing renewable energy, and other efforts to meet our sustainability goals of being carbon negative, water positive and zero waste by 2030,” they added.

Separately, a Google spokesperson told CNBC that research shows that while AI computing demand has dramatically increased, the energy needed to power this technology is rising “at a much slower rate than many forecasts have predicted.”
“We are using tested practices to reduce the carbon footprint of workloads by large margins; together these principles can reduce the energy of training a model by up to 100x and emissions by up to 1000x,” the spokesperson said.
“Google data centers are designed, built and operated to maximize efficiency – compared with five years ago, Google now delivers around 5X as much computing power with the same amount of electrical power,” they continued.
“To support the next generation of fundamental advances in AI, our latest TPU v4 [supercomputer] is proven to be one of the fastest, most efficient, and most sustainable ML [machine leanring] infrastructure hubs in the world.”

Elon Musk‘s xAI Holdings is in discussions with investors to raise about $20 billion, Bloomberg News reported Friday, citing people familiar with the matter.
The funding would value the company at over $120 billion, according to the report.
Musk was looking to assign “proper value” to xAI, sources told CNBC’s David Faber earlier this month. The remarks were made during a call with xAI investors, sources familiar with the matter told Faber. The Tesla CEO at that time didn’t explicitly mention any upcoming funding round, but the sources suggested xAI was preparing for a substantial capital raise in the near future.
The funding amount could be more than $20 billion as the exact figure had not been decided, the Bloomberg report added.
Artificial intelligence startup xAI didn’t immediately respond to a CNBC request for comment outside of U.S. business hours.
The AI firm last month acquired X in an all-stock deal that valued xAI at $80 billion and the social media platform at $33 billion.
“xAI and X’s futures are intertwined. Today, we officially take the step to combine the data, models, compute, distribution and talent,” Musk said on X, announcing the deal. “This combination will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach.”

Alphabet‘s stock gained 3% Friday after signaling strong growth in its search and advertising businesses amid a competitive artificial intelligence environment and uncertain macro backdrop.
“GOOGL‘s pace of GenAI product roll-out is accelerating with multiple encouraging signals,” wrote Morgan Stanley‘s Brian Nowak. “Macro uncertainty still exists but we remain [overweight] given GOOGL’s still strong relative position and improving pace of GenAI enabled product roll-out.”
The search giant posted earnings of $2.81 per share on $90.23 billion in revenues. That topped the $89.12 billion in sales and $2.01 in EPS expected by LSEG analysts. Revenues grew 12% year-over-year and ahead of the 10% anticipated by Wall Street.
Net income rose 46% to $34.54 billion, or $2.81 per share. That’s up from $23.66 billion, or $1.89 per share, in the year-ago period. Alphabet said the figure included $8 billion in unrealized gains on its nonmarketable equity securities connected to its investment in a private company.
Adjusted earnings, excluding that gain, were $2.27 per share, according to LSEG, and topped analyst expectations.

Alphabet shares have pulled back about 16% this year as it battles volatility spurred by mounting trade war fears and worries that President Donald Trump‘s tariffs could crush the global economy. That would make it more difficult for Alphabet to potentially acquire infrastructure for data centers powering AI models as it faces off against competitors such as OpenAI and Anthropic to develop largely language models.
During Thursday’s call with investors, Alphabet suggested that it’s too soon to tally the total impact of tariffs. However, Google’s business chief Philipp Schindler said that ending the de minimis trade exemption in May, which created a loophole benefitting many Chinese e-commerce retailers, could create a “slight headwind” for the company’s ads business, specifically in the Asia-Pacific region. The loophole allows shipments under $800 to come into the U.S. duty-free.
Despite this backdrop, Alphabet showed steady growth in its advertising and search business, reporting $66.89 billion in revenues for its advertising unit. That reflected 8.5% growth from the year-ago period. The company reported $8.93 billion in advertising revenue for its YouTube business, shy of an $8.97 billion estimate from StreetAccount.
Alphabet’s “Search and other” unit rose 9.8% to $50.7 billion, up from $46.16 billion last year. The company said that its AI Overviews tool used in its Google search results page has accumulated 1.5 billion monthly users from a billion in October.
Bank of America analyst Justin Post said that Wall Street is underestimating the upside potential and “monetization ramp” from this tool and cloud demand fueled by AI.
“The strong 1Q search performance, along with constructive comments on Gemini [large language model] performance and [AI Overviews] adoption could help alleviate some investor concerns on AI competition,” Post wrote in a note.

For 10 years, Aaron Cordovez has been selling kitchen appliances on Amazon. Now he’s in a bind, because most of his products are manufactured in China.
Cordovez, co-founder of Zulay Kitchen, said his company is moving “as fast as we can” to move production to India, Mexico and other markets, where tariffs are increasing under President Donald Trump, but are mild compared with the levies imposed on goods from China. That process will likely take at least a year or two to complete, he said.
“We’re making our inventory last as long as we can,” Cordovez said in an email.
Zulay is alsotemporarily raising the price of some of its milk frothers, smores roasting sticks and other products. The company’s popular kitchen strainer now costs $12.99, up from $9.99 before Trump announced his sweeping tariff proposal earlier this month.
Amazon merchants are hiking prices for everything from diaper bags and refrigerator magnets to charm necklaces and other top-selling items as they confront higher import costs. E-commerce software company SmartScout tracked 930 products on Amazon that have seen increased prices since April 9, with an average jump of 29%.
The price hikes affect a range of categories, including clothing, jewelry, household items, office supplies, electronics and toys.
The trade war with China has threatened to upend sellers on Amazon’s third-party marketplace, which accounts for about 60% of the company’s online sales. Many merchants are based in China or rely on the world’s second-largest economy to source and assemble their products.
Sellers are now faced with the conundrum of raising prices or eating the extra costs associated with Trump’s new tariffs. It’s an existential threat for many sellers, who subsist on razor-thin margins and have, for the last several years, dealt with rising costs on Amazon tied to storage, fulfillment, shipping and advertising fees along with pricing pressure from increased competition.
CEO Andy Jassy told CNBC earlier this month that the company was “going to try and do everything we can” to keep prices low for shoppers, including renegotiating terms with some of its suppliers. But he acknowledged some third-party sellers will “need to pass that cost” of tariffs on to consumers.
Amazon’s stock price is down 15% so far this year, sliding along with the broader market. The company reports first-quarter earnings next week.
Goods imported from China now face import duties of 145%, though Trump said Wednesday his administration is “actively” talking with China about a potential deal to lower tariffs. Chinese officials on Thursday denied that trade talks are taking place.
About 25% of the price increases observed by SmartScout were initiated by sellers based in China, said Scott Needham, the company’s CEO. Last week, stainless steel jewelry maker Ursteel hiked prices on four of its products by $6.50, while apparel brand Chouyatou raised the price of some of its dresses by $2. Both businesses are based in China’s Zhejiang province.
Anker, a Chinese electronics brand and one of Amazon’s largest sellers, has raised prices on one-fifth of its products sold in the U.S., including a portable power bank, which went up to $135 from $110, SmartScout data shows.
Representatives from Anker, Ursteel and Chouyatou didn’t respond to requests for comment.
Zulay, headquartered in Florida, is one of many U.S.-based sellers raising prices. The company is also cutting costs. Cordovez said he’s been forced to lay off 19% of his workforce and slash online ad spending by 85%.
Desert Cactus, based in Illinois, is also taking action. Joe Stefani, the company’s president, has been looking to move production of some of his brand’s college-themed merchandise out of China and into Mexico, India and Vietnam. About half of Desert Cactus’ goods come from China, while the rest are made in the U.S., Stefani said.

One of the company’s top products is a customizable license plate frame that’s manufactured in China. At the start of Trump’s first term in 2016, Stefani’s company paid import and shipping fees of 4% on the license plates. That rate has since skyrocketed to 170%, he said.
“The tariffs can’t stay this high,” Stefani said. “There’s so many people that just aren’t going to make it.”
Stefani said he expects Desert Cactus will end up raising prices on some products, though he’s worried shoppers might be put off by sticker shock.
“Will someone be willing to pay $50 for a hat on Amazon?” Stefani said. “You know it’s going to be expensive at the ballpark, but on Amazon we don’t know.”
Dave Dama, co-founder of health and beauty business Pure Daily Care, said the price to manufacture one of his skin-care products in China jumped to $25 from $10. Most Amazon sellers will have no choice but to raise prices, he said.
“If you were selling something for $40 and making a $7 or $8 profit at the end of the day, with these tariffs, those days are gone,” Dama said. “You can’t do that anymore. It’s unsustainable.”
Pure Daily Care plans to stagger price increases over several weeks, and only on products “we absolutely need to,” to keep Amazon’s algorithms from ranking it lower in search results or losing the valuable buy box, he said. The buy box determines which listing pops up first when a shopper clicks on a particular product, and the one that gets purchased when they tap “Add to Cart.”
An Amazon spokesperson said the company’s pricing policies continue to apply.
“As always, sellers set their own prices, and we regularly monitor how we highlight great prices as Featured Offers to provide customers with low prices across a wide selection,” the spokesperson said in a statement.
Dama said his company has enough inventory for some products to last up to six months, which it aims to “stretch as long as possible” in the hope that China and the U.S. can reach a trade deal. The company is also forgoing some sales promotions and discounts, while pausing spend on some display and video ads.
Regarding his inventory, Dama said, “We can try to stretch that seven, eight, nine months, which buys us a lot more time for this thing to work out, hopefully.”
