AI expends a lot o 投稿者：VincentCouth 投稿日：2025/07/17(Thu) 19:31 No.673997 
AI expends a lot of energy being polite, especially if the user is polite, saying please and thank you,

Dauner explained. But this just makes their responses even longer, expending more energy to generate each word.
For this reason, Dauner suggests users be more straightforward when communicating with AI models. Specify the length of the answer you want and limit it to one or two sentences, or say you dont need an explanation at all.
Most important, Dauners study highlights that not all AI models are created equally, said Sasha Luccioni, the climate lead at AI company Hugging Face, in an email. Users looking to reduce their carbon footprint can be more intentional about which model they chose for which task.
Task-specific models are often much smaller and more efficient, and just as good at any context-specific task, Luccioni explained.

If you are a software engineer who solves complex coding problems every day, an AI model suited for coding may be necessary. But for the average high school student who wants help with homework, relying on powerful AI tools is like using a nuclear-powered digital calculator.
Even within the same AI company, different model offerings can vary in their reasoning power, so research what capabilities best suit your needs, Dauner said.
When possible, Luccioni recommends going back to basic sources online encyclopedias and phone calculators to accomplish simple tasks.
Why its hard to measure AIs environmental impact
Putting a number on the environmental impact of AI has proved challenging.
The study noted that energy consumption can vary based on the users proximity to local energy grids and the hardware used to run AI models.
Thats partly why the researchers chose to represent carbon emissions within a range, Dauner said.
Furthermore, many AI companies dont share information about their energy consumption or details like server size or optimization techniques that could help researchers estimate energy consumption, said Shaolei Ren, an associate professor of electrical and computer engineering at the University of California, Riverside who studies AIs water consumption.
You cant really say AI consumes this much energy or water on average thats just not meaningful. We need to look at each individual model and then (examine what it uses) for each task, Ren said.
One way AI companies could be more transparent is by disclosing the amount of carbon emissions associated with each prompt, Dauner suggested.
