Data Centers vs Golf Courses: Which Wastes More Water?

Data center vs golf course water usage: nationally, golf courses use far more water than data centers, by a factor of roughly 2 to 30 depending on how you count it. But that comparison, pushed heavily by the AI industry, hides two things that matter more to the people affected: data center water use is growing about 20% a year and concentrates in a handful of drought-prone counties, while golf's water use is flat or falling. This guide breaks down both sides with sourced numbers so you can judge the claim yourself.

The short answer

Golf courses currently use more water than data centers do, nationwide, no matter how you slice the numbers. The Golf Course Superintendents Association of America puts total U.S. golf irrigation at roughly 1.63 million acre-feet in 2024, or about 531 billion gallons applied to turf. U.S. data centers used about 17.4 billion gallons directly on-site in 2023, according to research backed by the Lawrence Berkeley National Laboratory. That is roughly a 30-to-1 ratio in golf's favor.

AI companies and data center trade groups cite this stat constantly to deflect water criticism. It is technically true. But a national aggregate tells you nothing about what happens in the specific county where a hyperscale campus lands, and it says nothing about which industry is growing. Both of those gaps matter more than the headline ratio. See our broader explainer on how much water AI uses for the energy side of this story.

Data centers vs golf courses: the numbers

Here is the comparison across the dimensions that actually determine who is telling the truth.

The national totals, and where they come from

The golf number comes from the United States Golf Association and GCSAA's fourth Golf Course Environmental Profile survey, which measured applied irrigation water across thousands of U.S. courses in 2024. Applied water is what sprinklers put on the turf; a portion returns to the groundwater table rather than evaporating outright.

The data center number comes from Lawrence Berkeley National Laboratory's December 2024 federal report on U.S. data center energy and water use, which found about 17.4 billion gallons of direct, on-site water consumption in 2023 for cooling. That figure does not include the water used to generate the electricity data centers draw from the grid, since roughly half of U.S. power still comes from thermoelectric plants that also consume water to cool turbines.

Add that hidden power-plant water back in and the data center total climbs toward 228 billion gallons, per the same research, which narrows golf's lead to roughly 1.9-to-1 instead of 30-to-1. Which number is "correct" depends entirely on whether you count water used to make the electricity a data center buys. Most industry talking points quote the smaller, on-site-only figure.

Why the comparison is misleading

The Lincoln Institute of Land Policy has specifically flagged the golf-vs-data-center comparison as a distraction, noting that putting one water-heavy industry next to another does not make either one less wasteful. Three real gaps explain why the ratio understates the problem communities actually face:

• Applied water isn't consumed water. Golf's 531 billion gallons is water sprayed on grass; some percolates back into the aquifer. Data center water is largely evaporated in cooling towers and gone for good, so the two totals are not measuring the same thing.
• Golf is flat; data centers are exploding. Golf water use has slipped about 3% since 2020 as courses adopt drought-tolerant turf. Data center water demand is rising roughly 20% a year on the back of AI training and inference growth, a pace no other water user in the country is matching.
• National totals hide local damage. Golf's water use spreads across roughly 14,000 courses nationwide. AI data centers cluster into a small number of metro areas, so a single county can absorb the water footprint of dozens of golf courses at once from one shared local supply.

Local impact: where it actually hurts

Loudoun County, Virginia, the largest data center market in the world, supplied close to a billion gallons of water to data centers in a single recent year, almost all of it treated, drinking-quality water, not the treated wastewater some newer facilities use. That is a local utility system carrying a data center burden most counties will never see from golf.

Arizona shows the same pattern in reverse scale. Research from the University of Arizona's Water Resources Research Center found Phoenix-area golf courses use about 99,500 acre-feet a year across roughly 174 courses, versus about 2,777 acre-feet for operating data centers in the same county, a 35-to-1 golf lead locally. But a single hyperscale campus changes that math fast: Meta's Mesa, Arizona campus is projected to use about 1,400 acre-feet a year at full build-out, nearly three times the water of an average Phoenix golf course, from one property. You can track proposed and operating facilities near you on our data center map.

This is the core problem with citing a national ratio: it tells a Loudoun County or Mesa resident nothing about their own water bill, well levels, or drought restrictions. For the broader fight communities are waging over these facilities, see our guides on how to stop a data center in your community and data centers built on farmland.

When will data centers overtake golf?

Even on the smaller, on-site-only measure, data centers are closing the gap fast. EPA-backed projections put U.S. data center water consumption at 38 to 73 billion gallons by 2028, up from 17.4 billion in 2023, more than double even at the low end. Golf, meanwhile, is not growing; new course construction in the U.S. has been essentially flat for two decades, and existing courses are cutting water use, not raising it.

Run both trend lines forward and the central-case crossover point lands around 2026 to 2028, the same window the industry is racing to build new AI training capacity. Once that crossover happens, the "golf uses more water" talking point stops being true even in its most favorable framing.

Verdict: who's right?

Both sides are citing real numbers, but neither tells the whole story on its own. The industry is right that golf currently uses more water nationally. Critics are right that the comparison is a distraction from what is actually happening: fast, geographically concentrated growth that is landing on specific water systems, in specific counties, right now.

A national ratio cannot tell a resident of Loudoun County or Mesa whether their tap water is at risk. Only local permitting data, utility disclosures, and the facility's actual contract can do that. Check your own area on our data center map before accepting either side's talking point.

If you live near a proposed or existing data center, the national golf comparison is not the number that matters. The number that matters is how much water your specific utility has already promised away, and how fast that promise is growing.

Frequently asked questions

Do golf courses really use more water than data centers?

Yes, nationally. U.S. golf courses use about 531 billion gallons of applied irrigation water a year, versus about 17.4 billion gallons used directly by U.S. data centers, a roughly 30-to-1 ratio. Including the water used to generate data centers' electricity narrows that gap to under 2-to-1.

Why do AI companies compare data centers to golf courses?

AI and data center trade groups use the golf comparison to reframe water criticism as overblown, since the national totals favor them. The comparison is accurate as far as it goes, but it leaves out that data center water use is growing about 20% a year while golf's is flat, and that data centers concentrate their water demand in a handful of already water-stressed counties instead of spreading it across 14,000 courses nationwide.

How much water does a single data center use per day?

It varies widely by size and cooling design. A medium-sized data center can use roughly 100 million gallons a year, while a large hyperscale campus can consume 1 to 5 million gallons per day during peak cooling conditions, according to federal research. Meta's Arizona campus is projected to use about 1,400 acre-feet a year at full build-out, roughly 1.25 million gallons a day.

Will data centers use more water than golf courses in the future?

Likely yes, within a few years. EPA-backed estimates project U.S. data center water use reaching 38 to 73 billion gallons by 2028, more than double 2023 levels, while golf course water use has declined about 3% since 2020. Trend lines suggest data centers could overtake golf's on-site water use around 2026 to 2028.

Is data center water use worse for drought-stricken areas than golf?

It can be, locally, even where it is smaller nationally. About 40% of U.S. data centers operate in regions already facing high or extreme water stress, and a single hyperscale facility can use several times the water of one golf course from the same local supply. A national ratio does not reflect what happens to one county's water system when a large campus moves in.
