Auf einen Blick AI’s computational needs are growing more than twice as fast as Moore’s law, pushing toward 100 gigawatts of new demand in the US by 2030. Meeting this demand could require $500 billion in annual spending on new data centers. But even an aggressive reinvestment of IT and AI savings leaves a big gap. Technological and algorithmic breakthroughs could help, but supply chain shortages or insufficient power supply could also thwart progress. This article is part of Bain’s Technology Report 2025 Explore the report Of all the breathtaking observations about AI, few exceed this one: The growth rate for AI’s compute demand is more than twice the rate of Moore’s law (see Figure 1). For decades, Moore’s law—that is, the number of transistors on an integrated circuit doubles about every two years—has been the unrivaled measure of technological progress. If you apply its rate of progress to other fields of endeavor, the results are equally mind-blowing and amusing. For example, an automobile with Moore’s law applied would travel at 300,000 miles per hour, achieve 2 million miles per gallon of gas, and cost four cents. Now, AI’s compute demand—that is, the number of computations that must be performed to support evolving models—has grown at twice that rate over the past decade. With continued growth of these models and more adoption of AI by enterprises, Bain’s analysis suggests that the total global compute requirements could reach 200 gigawatts by 2030. In the US alone, total demand could reach 100 gigawatts by that time, which would increase new electricity demand on a grid that has seen relatively flat load growth for the past 20 years.

Technological and algorithmic breakthroughs could help, but supply chain shortages or insufficient power supply could also thwart progress.

Of all the breathtaking observations about AI, few exceed this one: The growth rate for AI’s compute demand is more than twice the rate of Moore’s law (see Figure 1).

For decades, Moore’s law—that is, the number of transistors on an integrated circuit doubles about every two years—has been the unrivaled measure of technological progress. If you apply its rate of progress to other fields of endeavor, the results are equally mind-blowing and amusing. For example, an automobile with Moore’s law applied would travel at 300,000 miles per hour, achieve 2 million miles per gallon of gas, and cost four cents.

Now, AI’s compute demand—that is, the number of computations that must be performed to support evolving models—has grown at twice that rate over the past decade. With continued growth of these models and more adoption of AI by enterprises, Bain’s analysis suggests that the total global compute requirements could reach 200 gigawatts by 2030. In the US alone, total demand could reach 100 gigawatts by that time, which would increase new electricity demand on a grid that has seen relatively flat load growth for the past 20 years.
