Electricity, water, carbon & cost of your AI usage โ€” sourced, adjustable estimates

Your AI usage

Pick a model and how much you use it โ€” everything else has sensible, sourced defaults

Longer, harder tasks use more energy per request

The window your request count covers

Assumptions โ€” adjust if you like

Carbon depends on where the data center's power comes from

Water use varies enormously by site and season

US residential average is about 19ยข/kWh (EIA)

Spread the one-time training run across all queries the model ever serves

How the numbers are made

Every figure is energy first โ€” water, carbon and cost are derived from it using the assumptions you pick

  • Energy per requestmodel estimate ร— task multiplier
  • Waterenergy ร— cooling intensity (L/kWh)
  • COโ‚‚energy ร— grid intensity (kg/kWh)
  • Electricity costenergy ร— price ($/kWh)
  • Training share (optional)training energy รท lifetime queries ร— your queries

โšก What one request costs

The best public anchors:

  • Google (official): median Gemini text prompt = 0.24 Wh, 0.26 mL water, 0.03 g COโ‚‚
  • OpenAI (official): average ChatGPT query โ‰ˆ 0.34 Wh
  • IEA: standard AI-agent request โ‰ˆ 1.1 Wh; agentic reasoning task โ‰ˆ 50 Wh
  • Univ. of Rhode Island lab: GPT-5 in reasoning mode โ‰ˆ 18 Wh average, up to 40 Wh
  • Epoch AI: long prompts (7,500 words in) โ‰ˆ 2.5 Wh; very long โ‰ˆ 40 Wh

๐Ÿ’ง Why water at all?

Data centers shed heat, often by evaporating water. UC Riverside researchers estimate roughly 500 mL per 5โ€“50 prompts depending on site and season. Efficient hyperscalers run near 1.1 L/kWh; hot-climate evaporative sites plus the water behind power generation can reach ~4 L/kWh, while closed-loop liquid cooling cuts direct use by 70โ€“90%.

๐ŸŽฌ Images & video are different

An image costs about as much as a long text answer (1โ€“3 Wh). Video is another world: independent measurements put an 8โ€“12 s clip anywhere from ~90 Wh to ~1,300 Wh (Sora 2 Pro at 1080p). OpenAI shut its Sora social app down partly because of exactly these compute costs.

๐Ÿ‹๏ธ Training vs. inference

Training a frontier model is a one-time run estimated at tens of GWh โ€” but amortized over the ~trillion requests a popular model serves, it adds only ~0.05โ€“0.1 Wh per query. Inference (usage), not training, now dominates AI's total footprint.

Honesty note: apart from Google's Gemini disclosure and OpenAI's single average figure, no provider publishes per-request energy. Everything else here is an independent estimate assembled from research (IEA, Epoch AI, Hugging Face AI Energy Score, ML.Energy, UC Riverside, Univ. of Rhode Island) with data-center overhead (PUE โ‰ˆ 1.2) included. Treat results as fair order-of-magnitude figures, not invoices. Bigger picture, for context: the IEA estimates data centers draw roughly 1.5% of the worldโ€™s electricity, with AI-focused facilities growing ~50% year over year.
