Is AI really using up our water and electricity?
You've probably heard something like it: a single AI question uses a bottle of water, or the new datacenters are draining the local reservoir. Maybe from a friend, maybe on the news. This page doesn't take a side. It does the arithmetic with things you already have at home: a teaspoon, a phone charger, a shower, and the TV in your living room. Every number is a link to where it came from.
The short version
A day of asking AI questions uses about a teaspoon of water and as much electricity as a minute and a half of television. Your shower, your coffee and your lunch each use years' worth of that. The questions worth asking about a new datacenter are how it's cooled and who pays for the power lines.
Part 1
First, the ruler
Four words you'll see, in plain English.
- Watt
- How fast something uses electricity, right now. The television on this page uses about 96 W.
- Watt-hour
- One watt, kept up for an hour. Your electric bill counts them by the thousand, as kilowatt-hours.
- Token
- What an AI counts instead of words. About three-quarters of a word each.
Water is in kitchen units throughout: teaspoons, cups and gallons.
Google says one AI question is "less than nine seconds of TV." So let's use a TV.
Google measured its own AI and published that comparison. Nine seconds of TV, at the energy they reported, works out to a television that draws about 96 W: an ordinary living-room set. That's the ruler for this whole page: one minute of that television. A minute of it uses a little electricity, and making that electricity uses a little water. The clock that just appeared in the corner counts how long you've been reading, and what your TV would have used in that time. It keeps running until the end.

Part 2
One day
Say you ask an AI four questions today.
A recipe, a work email, a homework check, something you were curious about at night. Behind those four answers the computer reads and writes about 8,000 tokens, including the thinking you never see. That's the day this page is built on.
One teaspoon = a minute and a half of TV.
Remember the television from the top of the page? Here is a whole day of AI, measured against it.
One teaspoonAll the water for the whole day: 1.1 teaspoons, counting the datacenter and the electricity it uses.
91 seconds of TVAll the electricity for the whole day: 2.42 Wh, including keeping the building cool. Run the 96-watt television for a minute and a half and you've used the same.
Hold on to both: one teaspoon, and a minute and a half of TV. Everything that follows is measured in days of this.
Where it actually goes.
The water: 81% of it evaporates at the power plant that makes the electricity, often hundreds of miles away. 19% cools the building. The electricity: about 83% goes to the chips themselves; 17% runs the cooling and the lights.
Water. Four drops in five evaporate at the power plant. One cools the building.
Electricity. Five parts in six reach the chips. One runs the cooling and the lights.
Part 3
Things you did today
Now compare that with things you did today without thinking.
Each one is counted the same way the AI was: everything it took to make it, from the field or the power plant to your hand. The numbers are in days or years of your daily AI use. Nobody is holding a hearing about your shower.

Charging your phone = five days of AI.
One full charge is about 13 Wh, 5.4 days of your AI. Making that electricity used about a tablespoon and a half of water, 23 mL, four days of your AI. Nobody thinks twice about the charger.
That's the electricity and the water it took to make it. The phone and the charger themselves aren't counted; both would make this bigger.
Tonight's phone charge is five days of AI questions.
5.4 daysof your AI, in electricity
4.3 daysof your AI, in water at the plant
One flush = three years of AI.
About 1.6 gallons per flush on a modern toilet, and 3.1 years of your daily AI use. Every flush, every day.
That's the water in the tank. Cleaning it and pumping it to your house aren't counted; both take electricity and would make this bigger.
One flush uses more water than three years of asking AI questions.
3.1 yearsof your AI, in water
No sourced electricity figure for a flush. It's mostly water, and this page doesn't guess.
Your coffee = 72 years of AI.
About 37 gallons to grow the beans for one cup, seventy-two years of your daily AI. Boiling the water for it is about 23.7 Wh, 9.8 days of your AI. The beans are the story, not the kettle.
That's growing the beans, rain included (only about 4.2 cups of it was pumped from a river or well), and boiling the water. The cup, the shipping and the milk aren't counted; each would make this bigger.
One cup of coffee is seventy-two years of AI questions.
72 yearsof your AI, in water
9.8 daysof your AI, to boil the water
Your shower = 33 years of AI.
An eight-minute shower is about 17 gallons, thirty-three years of your daily AI. If that number sounds familiar, it's the one from the meme: 17 gallons is a shower, not a question. Heating the water takes about 2,270 Wh, two and a half years of your AI.
That's the water and heating it. Cleaning it and pumping it to your house aren't counted; both would make this bigger.
This morning's shower was thirty-three years of AI questions in water, and two and a half years in electricity.
33 yearsof your AI, in water
2.6 yearsof your AI, to heat it
Your lunch = 256 years of AI.
About 132 gallons of water for a small fast-food hamburger, nearly all of it raising the beef: two and a half centuries of your daily AI. The energy to grow, process and cook it is ≈1,100 Wh, 1.2 years of your AI.
That's raising the beef and growing the bun, rain included. The restaurant, the packaging and the drive to get it aren't counted; each would make this bigger.
One hamburger is more water than a lifetime of asking AI questions.
256 yearsof your AI, in water
1.2 yearsof your AI, in energy
Tuesday's delivery = three years of AI.
Getting one parcel sorted at the depot and driven to your door takes about 2.81 kWh of energy, most of it diesel in the truck: 3.2 years of your daily AI. The depot's electricity also used about 2.7 cups of water back at the power plant, 4 months of your AI. Nobody is holding a hearing about Tuesday's delivery.
That's the depot and the drive to your door. The warehouse that stored the item, the box, and the truck that brought it across the country aren't counted, and every one of them would make this bigger.
One parcel to your door is three years of AI questions.

Part 4
Your screen day
Electricity, in phone charges.
Now the things you do on a screen: email, social media, streaming. Each is counted the whole way through, your device, the internet in between, and the datacenter at the far end. AI is counted exactly the same way, on the same rows. One phone icon is one full charge.
An evening of streaming is four months of AI questions.
One charge is 13 Wh. Every row is counted the whole way through.
The same four things, in measuring cups of water.
One icon is one measuring cup, the kind in a kitchen drawer. Three hours of streaming is three cups. Your four AI questions are about a teaspoon and a half. Almost all of this water evaporated at a power plant, not at a datacenter, and nobody wrote a headline about the streaming.
Part 5
The country
Fair question: a teaspoon times 340 million people is a lot of teaspoons.
So count the whole country the same way, in water pumped from rivers and wells. Every US datacenter, counting the electricity they use and everything they do, your email and your bank as well as AI: about 211 billion gallons a year. The country's golf courses use twice that. California's almond orchards use three times it, and beef about eight times (684 billion gallons and 1,786 billion gallons; the sources page has the full table). Datacenter water use is projected to roughly triple by 2030 (≈3×), which would put it past golf and still below almonds.
LBNL, GCSAA The datacenter figure is understated by about 8%; the source note says why.
And the electricity: about four cents on every dollar.
Every US datacenter together used about 176 TWh in 2023, roughly 4.4% of the country's electricity, and again that's everything they do, not just AI. Home air conditioning alone uses more; electric water heaters use about the same (156 TWh); clothes dryers about a third of it (56 TWh). Nobody proposes to switch any of those off. Datacenter electricity is projected to reach about 649 TWh by 2030, which is the number a grid planner works with.
All of it on one shelf.
Everything on this page, biggest to smallest. Each one equals this much of your daily AI use.

Part 6
The payoff
A full day of AI costs under two minutes of television. In electricity, and in water.
91 seconds of electricity. 112 seconds of water. Count your device and the internet too, on both sides, and it's 92 and 105. However you count it, between a minute and a half and two minutes. That is what the name of this page means.
The only way to make AI look worse is to count everything for the AI and only the set for the TV; the sources page shows why this page doesn't.
You've been reading for 0:00.
If your TV had been on that long, it would have used about 0 of your AI. That's the clock in the corner. Now pick the one that sounds like you.
Five minutes of television is ≈3 days of AI use. Your year, for the typical day:
For the typical day: AI, about nine cents of electricity and about 11 cups of water. Streaming, about ten dollars and four showers' worth. Social, about two dollars. The heavy user's AI line reads about $1.79 a year and 45 minutes of TV a day, and says so.
Part 7
If you've heard datacenters are a problem, here's the part that's true.
If you've been avoiding AI because of what you've heard about datacenters, here is what's true in it and what isn't.
Which AI you use matters. The simplest answers cost a fraction of a watt-hour; a long answer from the heaviest "reasoning" models can cost ≈18 Wh. Someone who uses those all day is at 45 minutes of TV, not two. Still a quarter of the three hours most people watch, but a real difference, and the two minutes is the typical day.
The total is growing fast, even as each person's share is tiny: 176 TWh of electricity in 2023, heading for about 649 TWh by 2030. Both things are true at once, and the people who plan the power grid work with the total.
Your electric bill can go up, and it depends on where you live. A building this size needs new power lines and sometimes new power plants, and your state's utility commission decides who pays. Virginia's own auditor found datacenters pay their full costs today, and projected a typical household's bill could be $14 to $37 a month higher by 2040, which is $168 to $444 a year. For proportion, household electricity prices across the country rose about 32% from 2020 to 2025, mostly to pay for aging power plants and lines. In the mid-Atlantic power grid, the independent monitor ties about 46.2% of recent charges for keeping enough power plants available to datacenter demand. Yet a national lab found that, so far, states where electricity use grew fastest generally saw prices fall after inflation (0.6 cents/kWh for every tenth more use). Since 2025, Ohio, Indiana, Georgia and Virginia have adopted rules that make very large customers pay their own way.
A national average says nothing about your town. Nothing on this page tells you what one building does to one well, one substation or one county's taxes. If there's a datacenter proposed near you, ask for that building's numbers. That's a fair question, and the next page shows what the answer depends on: mostly how the building is cooled.
Part 8
Nobody's asking you to give up your shower.
Or your coffee, your phone charger, Tuesday's delivery, or tonight's three hours of TV. A day of AI questions belongs on that shelf, at the small end: a teaspoon, and under two minutes of the television.
So the question worth asking about a datacenter isn't whether it uses water. It's how the building is cooled, and who pays for the new power lines. Those are real questions with real answers.
0:00 reading. 0 of your AI.
Five minutes of reading with the TV on would have been ≈3 days of your AI.
