How Much Energy Do Data Centers and Artificial Intelligence Use?

I explore the global electricity consumption of data centers, which currently account for 1.5% of the world's supply, with AI specifically using about 0.5%. While global demand remains manageable, the geographic concentration of these facilities creates significant strain on local grids in places like the US and Ireland. I also break down the surprisingly low energy cost of individual AI queries, offering clarity on the environmental impact of using tools like ChatGPT and Gemini.
