Summary
To run complex computations quickly, AI systems require powerful chips, multiple GPUs, and expansive data centers, all of which consume power when you ask ChatGPT a question.

Still, even as an estimate, 45 minutes of LED bulb use seems anecdotally high, which puts the energy used by much more complex, multi-step prompts into perspective. Only AI companies know how much energy their systems really use, but studies estimate that, based on demand trends, it's only increasing.
