Estimate the electricity consumption of training or serving an AI model.
Total data center energy consumption exceeds the raw power draw of GPUs alone because of cooling, power distribution losses, and other facility overhead — captured by the PUE (Power Usage Effectiveness) metric. This calculator computes GPU energy use directly from TDP × count × hours, then applies the facility's PUE multiplier to estimate total energy drawn from the grid, which feeds directly into carbon emissions estimation.
total_kwh = (gpu_tdp_watts × gpu_count × hours / 1000) × PUE
Modern hyperscale data centers achieve PUE values around 1.1-1.2, while older or less efficient facilities can run 1.5-2.0 or higher.
TDP is a manufacturer rating that approximates peak sustained draw; real-world average utilization during training is often 70-95% of TDP, so this is a reasonable upper-bound estimate.
Feed the totalKwh result into the Carbon Emission Calculator (AI) along with your grid's carbon intensity to get a CO2 estimate.
