Very little. Viro AI runs in data centers cooled by cold outside air and closed-loop liquid systems that recirculate their water instead of evaporating it, so they consume only a small fraction of the water a typical data center does.
AI runs on servers that turn electricity into heat. Many data centers remove that heat with cooling towers that evaporate water, consuming around 1.8 liters of water for every kilowatt-hour of electricity they use. The more computing an AI does, the more water those data centers consume.
Every data center uses some water, so no AI uses none. What matters is how much is consumed: evaporated and lost, rather than returned or reused. Viro AI's data centers recirculate their cooling water in closed loops and lean on cold outside air, so what they consume is a small fraction of evaporative cooling. Viro AI also sends simple questions to small, efficient models, which means less computing, and less heat to remove, for each reply.
- Akureyri, Iceland: direct liquid cooling and cold Atlantic air. Its waste heat warms a community greenhouse.
- Blönduós, Iceland: the Arctic climate carries most of the cooling load all year.
- Glomfjord, Norway: fjord water cools the racks in a closed loop and is returned to the fjord, and about 85% of the waste heat is headed for nearby fish farms.
These sites run at a power usage effectiveness (PUE) of 1.03 to 1.31, so nearly all of their electricity goes into computing rather than cooling and other overhead. See Our Data Centers.
They run in their providers' own data centers, so their cooling and water use are set by those providers. To use the model that runs in Viro's low-water, clean-energy data centers, choose Viro AI, which is the default.
Not yet. The ⚡ estimate under each reply covers electricity. Viro plans to add water as reliable, comparable research on it matures. See Energy & Impact and Is Viro AI Eco-Friendly?
Does Viro AI use water?
Very little. Viro AI's data centers are cooled by cold outside air and closed-loop liquid systems that recirculate their water instead of evaporating it, so they consume only a small fraction of the water a typical data center does.
Is there an AI that doesn't use water?
Every data center uses some water, so no AI uses none. What matters is how much is evaporated and lost. Viro AI runs in data centers that recirculate their cooling water in closed loops and rely on cold outside air, so they consume only a small fraction of what evaporative cooling does.
Which AI uses the least water?
Look for AI that runs in data centers cooled by outside air and closed-loop systems rather than evaporative cooling towers, which consume around 1.8 liters of water per kilowatt-hour. Viro AI runs in data centers like that, in Iceland, Norway, Ireland, and Finland.
