In it, we discuss how transparency around the environmental impacts of AI has been declining over the years, resulting in a total lack of disclosure about the most popular models that we use now, precluding us from making informed choices. 💻

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! arxiv.org/abs/2506.15572

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).

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!

There aren't enough GPUs in enough regions in order to make this possible - they're mostly concentrated in e.g. Iowa, Ireland, Taiwan. There are some partially solar-powered datacenters, but they aren't the hyperscaler ones needed for distributed inference.
