The resource footprint
Modelled averageIn one day, this campus consumes about
2.6950-metre swimming pools
Filled with the volume of water consumed by the campus and its electricity supply.
The actual estimate1,777,032 US gallons consumed
Power-plant water may come from a different watershed. This is a volume comparison, not a claim that households lose this water.
At current operating capacity · Annual model spread evenly over time, not a live meter. Site estimates may differ by roughly ±40%.
Comparison sizes & sources
One pool = 50 × 25 × 2 metres = 2.5 million litres (about 660,430 US gallons). Pool depths vary; this is a defined comparison size.
One home-year = 10,791 kWh, the EIA’s 2022 average US residential electricity purchases. This excludes electricity generated at home and is a fixed US benchmark for all sites.
One car-year = 4.6 tonnes CO₂, the EPA’s typical passenger vehicle tailpipe estimate. The campus model is in CO₂e; the comparison expresses approximate climate scale, not equal mixtures of pollutants.
Monthly values are annual totals ÷ 12; daily values are annual totals ÷ 365. Actual demand varies. Comparisons cover the whole campus, including non-AI uses.
Water: see the numbers and sources
This is water used up, mainly through evaporation. Power-generation water may be used in a different watershed.
- Pressure on local water
- High — a regional measure of demand compared with available water
- Where the water comes from
- Surface water — river, lake or canal
- Cooling
- Evaporative with adiabatic assist; irrigation-canal water rights
- Basis
- Fitted to a published figure of 200 million gallons a year
Air: see the numbers and sources
The totals include nitrogen oxides, sulphur dioxide and fine particles. They cover both this site and the power plants supplying it.
- Health range
- $5.38–15.3 million a year. Lower bound is EASIUR national mid-range; upper is EPA benefit-per-ton at a ~$12M VSL.
- Statistical deaths
- 1.27 a year at that VSL — a national-average conversion from tons, not a local concentration study.
- Equals
- 212,211 cars of NOx
- Where it burns
- Spain — Red Eléctrica
- Generation mix
- Wind 24 · Nuclear 20 · Solar 21 · Gas 18
- Diesel backup
- Diesel backup is not yet counted for this campus, so on-site air figures are a floor.
- CO₂e
- 310 kt/yr — climate, not air quality
The project, approvals and community concerns
- Who asked for it
- AWS — self-build and European cloud customers
- Who approved it
- Government of Aragón authorised abstractions totalling roughly 755,000 m³/yr from the Ebro basin; regional incentives supported a €15.7B expansion announced in 2025
- What it serves
- AWS eu-south-2 region
- IT capacity
- 250 MW current capacity / 900 MW full-build scenario
Farmers' associations in the Ebro valley have objected to water being allocated to cooling in a basin already under drought restriction. Aragón is now the biggest single cloud investment in southern Europe.
