Key quotes
AI energy consumption is the electricity used to train and run AI models, from the computing clusters that build a model to the servers that answer your questions in real time.
A single AI response typically uses a small fraction of a watt-hour, but the exact figure depends heavily on which model answers your question.
By 2028, AI-related demand is projected to climb to between 165 and 326 terawatt-hours a year,
You can't control how a data center is powered, but you can lower your own footprint.
This EcoFlow article examines the energy consumption of popular AI models like ChatGPT, Claude, and Gemini in 2026. It highlights how individual queries require fractional watt-hours, but collective usage strains data centers, potentially changing grid demand and utility costs. The piece also suggests ways to mitigate personal energy footprints, such as using portable power stations or solar generators, and compares AI energy use to household electricity consumption.
