As the AI industry booms, what toll will it take on the environment?

One question that ChatGPT can't quite answer: how much energy do you consume? "As an AI language model, I don't have a physical presence or directly consume energy," it'll say, or: "The energy consumption associated with my operations is primarily related to the servers and infrastructure used to host and run the model." Google's Bard is even more audacious. "My carbon footprint is zero," it claims. Asked about the energy that is consumed in its creation and training, it responds: "not publicly known".
