Electricity consumption from the manufacture of artificial intelligence (AI) chips has soared by more than 350 percent worldwide between 2023 and 2024, according to new research from Greenpeace East Asia. In East Asia, the global hub for AI semiconductor production, growing electricity demand from AI chipmaking has been met primarily by fossil fuels, the research finds. To assess the global climate impact of AI chipmaking, this research estimates the electricity consumption of the dominant AI chip models (Nvidia A100, H100, H200, B100/200 and AMD MI300X) in 2023 and 2024 and emissions from their electricity consumption using a bottom-up approach.
