Is an AI Energy Crisis Looming?

The AI and cloud revolution is triggering an unprecedented surge in electricity demand, exposing the physical limits of current power grids. While data centers were already expanding, AI’s high-intensity compute requirements accelerate this growth, necessitating a shift away from the recent trend of decommissioning reliable power sources. Because efficiency gains have largely plateaued, meeting this demand requires a return to baseload generation, including nuclear, coal, and natural gas. Mark P. Mills, Executive Director of the National Centre for Energy Analytics, argues that the cloud’s physical infrastructure—measured in billions of miles of network and massive square footage—is currently in its infancy. Consequently, the immediate future will likely see a reliance on gas turbines and a strategic pivot toward nuclear energy, as the economic necessity of reliable power outweighs the current political focus on episodic, weather-dependent energy sources.
