The Growth of AI and Its Energy Demands

The rapid expansion of artificial intelligence (AI) has led to more than one and a half billion global users since the introduction of chatbots like chat GPT, highlighting the technology's growing prevalence. However, this surge in AI usage is coinciding with significant challenges for the U.S. electricity grid, which is already under strain from rising electricity demands. The data centers powering AI operations are notoriously energy-intensive, requiring a mix of carbon-free and fossil fuel-generated electricity, complicating efforts to decarbonize. The increase of AI workloads in data centers currently accounts for approximately 12% of their total energy consumption, and as AI continues to grow, managing its energy impact becomes increasingly critical.
