Calculator

Your AI footprint

Estimate the water, energy and carbon behind your AI use, with sources for every number.

Type it the way you'd say it. The dials below follow.

Model

What gets counted

The same prompt can be “five drops” or “a bottle of water” depending on what you count: just data-center cooling (Low), the water behind the electricity (Mid), or training and hardware too (High).

  1. 01

    Say it or set it

    Describe your use in a sentence, or set the model, usage and timeframe by hand. Both drive the same dials.

  2. 02

    Tokens become energy

    Each model sits in a benchmarked energy class, or uses its official figure where one is published.

  3. 03

    Energy becomes water

    Multiplied by the factor for the boundary you pick: cooling only, plus electricity, or the full lifecycle.
