New research reveals that AI reasoning models demand significantly more energy, raising concerns about their impact on power grids. These models consume, on average, 100 times more power than simpler counterparts, with one model from DeepSeek needing 308,186 watt-hours to respond to prompts with reasoning enabled. Sasha Luccioni, of Hugging Face, emphasizes the need for smarter model selection. Microsoft CEO Satya Nadella stresses the importance of earning social permission for AI's energy consumption.
