More than 4,500 active data centers across the United States consume about 176 terawatt-hours of electricity each year, equal to roughly 4.4% of total national power use, according to industry data. Another 700 or more facilities are under construction across 38 states, pointing to sustained growth in the sector's energy footprint.

The figures illustrate how quickly computing infrastructure has become a significant driver of electricity demand. Data centers now sit alongside traditional industrial users as a major category of consumption, and their share is rising faster than most other segments of the grid.

Regional concentration is a defining feature of the map. A handful of states account for an outsized portion of capacity, while permitting, land, and power availability shape where new projects can proceed. The distribution is shifting as developers seek regions with accessible generation and shorter interconnection queues.

The scale of current consumption sets a baseline that is expected to grow substantially. With hundreds of facilities in the construction pipeline and demand for artificial intelligence workloads rising, the sector's electricity use is positioned to expand well beyond the current 176 terawatt-hour level, adding to the load that utilities must plan to serve in the years ahead.
