AI Data Center Power Demand
Artificial intelligence has changed the scale of data center power. Training and serving large models takes racks of GPUs that draw far more power than traditional servers, and the biggest planned campuses are measured in gigawatts rather than megawatts. That growth is a major reason utilities and grid operators have raised their load forecasts, and why technology companies are signing deals for gas, nuclear and grid supply.
The numbers are easy to misread, so this section focuses on how they are built. It explains how much power a single GPU, a rack and a campus use, what share of U.S. electricity data centers consume, and why forecasts for the coming years disagree so widely. It looks at how hyperscalers and newer GPU cloud providers are securing power, how much energy a single query uses according to published estimates, and whether chips, models and cooling are getting more efficient. The guides link to their sources so you can check the figures. Use the PUE calculator to turn an IT load into facility power and yearly energy cost.
