AI’s carbon footprint is bigger than you think

World leaders are currently in Dubai for the UN COP28 climate talks. As 2023 is set to become thehottest year on record, this year's meeting is amoment of reckoning for oil and gas companies. There is also renewed focus and enthusiasm onboosting cleantech startups. The stakes could not be higher.

But there's one thing people aren't talking enough about, and that's the carbon footprint of AI. One part of the reason is that big tech companies don't share the carbon footprint of training and using their massive models, and we don't havestandardized ways of measuringthe emissions AI is responsible for. And while we knowtraining AI models is highly polluting, the emissions attributable tousingAI have been a missing piece so far. That is, until now.

I justpublished a storyon new research that calculated the real carbon footprint of using generative AI models. Generating one image takes as much energy as fully charging your smartphone, according to the study from researchers at the AI startup Hugging Face and Carnegie Mellon University. This has big implications for the planet, because tech companies are integrating these powerful models into everything from online search to email, and they get used billions of times a day.If you want to know more, you can read the full story here.

Cutting-edge technology doesn't have to harm the planet, and research like this is very important in helping us get concrete numbers about emissions. It will also help people understand that the cloud we think that AI models live on is actually very tangible, says Sasha Luccioni, an AI researcher at Hugging Face who led the work.

Once we have those numbers, we can start thinking about when using powerful models is actually necessary and when smaller, more nimble models might be more appropriate, she says.

Vijay Gadepally, a research scientist at the MIT Lincoln lab who did not participate in the research, has similar thoughts. Knowing the carbon footprint of each use of AI might make people more thoughtful about the way they use these models, he says.

Luccioni's research also highlights how the emissions related to using AI will depend on where it's being used, says Jesse Dodge, a research scientist at the Allen Institute for AI, who was not part of the study. The carbon footprint of AI in places where thepower grid is relatively clean, such as France, will be much lower than it is in places with a grid that is heavily reliant on fossil fuels, such as some parts of the US. While the electricity consumed by running AI models is fixed, we might be able to reduce the overall carbon footprint of these models by running them in areas where the power grid consists of more renewable sources, he says.

While climate change is extremely anxiety inducing, it's vital we better understand the tech sector's effect on our planet. Studies like this one might help us come up with creative solutions that allow us to reap the benefits of AI while minimizing the harm.

After all, it's hard to fix something you can't measure.

Deeper Learning

Google DeepMind's new AI tool helped create more than 700 new materials

From EV batteries to solar cells to microchips, new materials can supercharge technological breakthroughs. But discovering them usually takes months or even years of trial-and-error research. A new tool from Google DeepMind uses deep learning to dramatically speed up the process of discovering new materials.

What's the big deal:Called graphical networks for material exploration (GNoME), the technology has already been used to predict structures for 2.2 million new materials, of which more than 700 have gone on to be created in the lab and are now being tested. GNoME can be described as AlphaFold for materials discovery. Thanks to GNoME, the number of known stable materials has grown almost tenfold, to 421,000.Read more from June Kim here.

ChatGPT is leaking its secrets
Two new stories show how vulnerable AI chatbots are to leaking data, putting personal and proprietary information at risk. The first story, byWired, shows how easily OpenAI's custom ChatGPT bots spill the initial instructions they were given when they were created. Another one, by 404 Media, shows how researchers at Google DeepMind were able to get a chatbot to reveal its data by asking it to repeat specific words over and over.
