How to Use

Scenario arithmetic only: every rate, lifecycle factor, and boundary is entered explicitly; no regional defaults or hidden datasets are used.

Use Cases

Compare AI model deployment scenarios

Use this calculator to compare the environmental impact of different AI models or deployment strategies by adjusting the energy per request and other parameters.

Example: Compare a lightweight model (0.001 kWh/request) vs. a heavy model (0.01 kWh/request) for 1 million requests.

Estimate data center resource needs

Plan for water and energy resources in data centers by estimating the total consumption of AI workloads, helping with sustainability reporting and capacity planning.

Example: Estimate water usage for 10 million requests with 0.005 kWh/request and 2 L/kWh.

Frequently Asked Questions

What does this calculator estimate?
This calculator estimates the total energy consumption, water usage, and carbon dioxide equivalent emissions for a specified AI workload. You provide the number of requests, energy per request, water per kWh, and electricity emissions factor, and it calculates the totals.
How is water usage calculated?
Water usage is calculated by multiplying the total energy consumption (in kWh) by the water intensity factor (in liters per kWh). This gives an estimate of the water used for cooling and power generation associated with the AI workload.
What is the electricity emissions factor?
The electricity emissions factor represents the amount of carbon dioxide equivalent (CO₂e) emitted per kilowatt-hour of electricity consumed. It varies by region and energy mix. This calculator uses it to estimate the carbon footprint of the AI workload.

Tips & Common Mistakes

Tips

  • Use realistic values for energy per request based on your hardware and model size. You can find benchmarks or measure it directly.
  • Adjust the water per kWh factor based on your data center's cooling technology and local climate. Evaporative cooling uses more water than air cooling.
  • Choose an electricity emissions factor that matches your region's grid mix. Many countries publish average values annually.
  • Run multiple scenarios to see how changes in request volume or efficiency affect the total footprint.

Common Mistakes to Avoid

  • Using the same energy per request for all requests without considering variations in model complexity or input size.
  • Forgetting to convert units, such as using megawatt-hours instead of kilowatt-hours, leading to incorrect totals.
  • Using a generic emissions factor without accounting for the specific energy mix of the region where the AI workload runs.
