As tech firms keep adding the largest and most compute-intensive AI models into more and more aspects of our digital lives, they are increasingly dependent on a growing share of existing energy and natural resources, leading to rising costs for everyone else, write Sasha Luccioni and Yacine Jernite.

In our commentary, @yjernite.bsky.social and I explain how AI & data center expansion is making energy bills rise in the US, what the mechanisms driving this are, and why it matters.

I am so grateful that this paper is out!
It so eloquently describes so many of the issues I've seen with a lot of AGI experimentation that concludes that LLMs are scheming, ill-intentioned, or malicious, and the chimp language metaphor is the cherry on the cake 🍰

Does a ChatGPT query really use ten times more energy than a Google search? Does training any AI model emit as much CO2 as 5 cars? and can AI help us reduce global GHG emissions by 10%? 🤔
We tracked down the origins of these numbers 🕵♀️ and wrote a paper about it!

How Much Energy Does AI Use? The People Who Know Aren’t Saying

One of the biggest frustrations I have is the lack of transparency around AI's energy use and environmental impacts. I know the numbers are out there... but somehow we're not seeing them 🫠

People saying "thank you" to ChatGPT is apparently costing OpenAI tens of millions of dollars -- but how does that translate to energy? ⚡
We ran some experiments where we show that the total energy consumed is ~0.245 Wh (roughly equivalent to powering a 5 W LED bulb for approximately 3 minutes).

Also - SHOW 👏 US 👏 THE 👏 DAMN 👏 RECEIPTS
Finally some numbers about ChatGPT's energy and water use? ⚡
Even if this is the true amount of energy used for a query (and that's a big if!), multiplied by the billions of queries a day, this adds up massively.
And that's not counting image generation, which is much more energy-intensive!
