A single, large-scale AI data center campus can now demand several gigawatts of power — enough electricity to run a small city. This staggering consumption is no longer a distant forecast; it is the new reality of the digital economy, and it is sending shockwaves through the global energy system. The AI revolution has ignited a voracious and unprecedented demand for electricity. Projections indicate that U.S. data center grid-power demand will nearly triple by 2030, a trend mirrored globally, where demand is expected to double in the same timeframe.
