The University of Rhode Island’s AI lab estimates that GPT-5 averages just over 18 Wh per query, so putting all of ChatGPT’s reported 2.5 billion requests a day through the model could see energy usage as high as 45 GWh.
A daily energy use of 45 GWh is enormous. A typical modern nuclear power plant produces between 1 and 1.6 GW of electricity per reactor per hour, so data centers running OpenAI’s GPT-5 at 18 Wh per query could require the power equivalent of two to three nuclear power reactors, an amount that could be enough to power a small country.
Me, personally, we have trees and shade. So many subdivisions don’t, and they have dark colored roofs, and then homeowners do bone-headed things like adding “sun rooms” - lots of those in Houston.
We get upset when our electric bill passes $300 for the month, but our neighbors with the 3500 sq ft? They never see it under $400.
