Cows drink rain. Data centers drink your tap.
The Commerce Secretary told CNBC that data centers “don't use water” and pointed at cattle instead. The comparison hides the one thing that matters to your town: where the water comes from.
We grade what is documented — the quote, the water numbers, and his own earlier pitch that said the opposite. Then we mark clearly the part we can't prove: why he said it.
What this page is about
On CNBC, Commerce Secretary Howard Lutnick said data centers “don't use water” and that the biggest water user in America is cattle. He called worry about data-center water use “propaganda.” Both parts are wrong in a way that matters. Data centers do use water — about 66 billion liters in the US in 2023 — and most of it is the treated tap water and groundwater a town drinks. The cattle comparison hides where the water comes from: more than 90% of a cow's water is rain that fell on its grass and feed, not water pumped from a well or a reservoir.
A year before calling the concern “propaganda,” Lutnick had sold states on data centers partly by pointing to how much water they use. This page grades the documented facts and marks clearly where we stop.
The quote, the water, and the reversal
Lutnick said data centers 'don't use water' and pointed at cows instead.
FACTOn CNBC, Commerce Secretary Howard Lutnick said 'data centers don't use water' and that 'the No. 1 product in America that uses water is cattle.' In a separate 2026 appearance he called concern about data-center water use 'propaganda.' The clips exist and he said this on the record.
“One of my favorite things is when people talk about data centers using water. The No. 1 product in America that uses water is cattle.”
Data centers do use water — a lot of it, and the kind that comes from a tap.
FACTUS data centers used about 66 billion liters of water in 2023, most of it at the largest sites, according to a 2024 report from the Lawrence Berkeley National Lab. That water is mostly treated drinking water and local groundwater used to cool the servers — the same supply a town pulls from its reservoirs and wells. Communities have fought new data centers over exactly this.
The cow comparison hides the one thing that matters: where the water comes from.
FACTMore than 90% of the water counted against a cow is rain that fell on the grass and feed it eats. Researchers call this 'green water,' and it was never in a pipe, a reservoir, or a well. Only a small slice — about 4% in the US — is 'blue water,' the surface water and groundwater people actually drink. A data center's cooling water is almost all blue water, drawn straight from the drinking supply. Comparing the two treats rain on a field as if it were the same as pumping a town's wells.
This is not an honest mistake — he said the opposite himself a year earlier.
FACTIn a May 2025 interview, Lutnick pitched states on data centers partly by pointing to how much water they use — describing jobs for people to monitor the 'huge amounts of water being sucked into the center' to cool it. In 2026 he flipped, calling the same water use 'propaganda' and saying data centers 'don't use water.' His own earlier words are the evidence that he knows better: you cannot forget that data centers use water when you spent 2025 selling states on exactly that. This is a knowing reversal, not confusion about cows.
The false claim serves the data-center industry, not the public.
PROBABLY TRUEBeing wrong this way carries a political cost and no political reward: it puts a top official on the side of a water grab that voters dislike. So the lie is not for the public. It has one clear beneficiary — the data-center buildout the administration is racing to expand, and the companies behind it. A false 'they don't use water' clears an objection that stands between those companies and a town's water. We grade the direction of the benefit — industry over public — as the strong reading. We stop short of naming the private motive (see §3).
At the same time, the administration is sharply raising beef imports from Argentina.
FACTIn February 2026 the administration quadrupled the low-tariff limit on Argentine beef, from 20,000 to 100,000 metric tons for the year. On August 21, 2026 the president announced letting in 300,000 metric tons of 'product for ground beef' to lower US prices. Argentina's president, Javier Milei, is one of Trump's closest allies. This is FACT about the trade policy; any link to the water remark is a separate question we do not answer here.
What's solid, and what we won't claim
- The facts are documented. The quote, the water numbers, the green-water math, and his own 2025 pitch are all on the record. That is why they grade to FACT.
- It's a knowing lie, not a slip (FACT).He sold states on data-center water use in 2025, then said they “don't use water” in 2026. His own earlier words are the proof he knows better, so “he got confused about cows” does not survive.
- Who it serves is clear; his private motive isn't (SOME SMOKE). That the lie helps the data-center industry and not the public is the strong reading (PROBABLY TRUE) — there is no voter upside to being wrong about a water grab. What we can't separate is the private why: is he doing a favor for investors and donors, or protecting his own drive to build AI fast? Both fit the record; the evidence does not pick one, so we don't.
- The beef angle is thin smoke, not nothing (SOME SMOKE).He reached for cattle in particular, at the same moment the administration is pushing a large and contested expansion of Argentine beef imports. Praising cattle while quadrupling beef imports is a real thread worth naming. But cattle is also just the obvious water comparison — it genuinely is a huge water user — so the overlap could be coincidence. We flag it as SOME SMOKE: some reason to wonder, not a claim.
Towns are being asked to hand over their water
Across the country, towns are being asked to give a data center a cheap deal on land, power, and water. When a top official tells them the water use is “propaganda,” it gets harder to ask the plain question: how much of our drinking supply are we handing over, and for what? That is the same trade we tracked in The Data-Center Giveaway, and it is why this sits in Looting the American Public: a public resource handed to private interests, with the public told not to worry about it.
Questions worth taking seriously
Don't cows really use a huge amount of water?
Yes, the total number is large — but almost all of it is rain that grew the grass and feed, not water from a tap or a well. The figure sounds enormous because it counts the rain. That is the exact part the comparison leaves out.
Do data centers really use drinking water?
Yes. Many cool their servers with treated tap water and pull from local groundwater — the same supply a town drinks from. US data centers used about 66 billion liters in 2023.
Are you saying the beef imports and the water comment are connected?
Not as a proven link — we can't show one, so we don't claim it. But it's fair to wonder: he reached for cattle in particular while the administration is expanding Argentine beef imports. We flag that as thin smoke worth naming and stop there. The documented part is the misleading water comparison and the reversal of his own earlier pitch.
