Every AI prompt has a power cost most people ignore.
Training one large AI model like GPT-4 can use as much electricity as about 100 US homes consume in a year.
That is just training it once.

ChatGPT alone handles over one billion queries per day.
Each query pulls about half a watt of energy.
That is like running your microwave for two to three seconds.
For every single prompt.
AI feels invisible.

The real conversation is not just about innovation.
It is about scale, power demand, and long term infrastructure.
If you are building in AI, factor energy into the equation.
