EIA predicts: In 2050, data center electricity consumption will be 16 times that of 2020.

The latest report from the U.S. Energy Information Administration (EIA) shows that data center power demand will experience explosive growth over the coming decades, becoming a core variable reshaping the U.S. energy landscape.

Under a high power demand scenario, the EIA predicts that by 2050, electricity consumption by data center servers will reach 818 billion kilowatt-hours, more than 16 times the 2020 level. This means that by then, data center servers will account for 22% to 33% of total commercial building electricity consumption.

This forecast has direct implications for energy infrastructure investors and power market participants. The continuously rising data center load will drive overall U.S. electricity consumption to grow at an annual rate of 0.9% to 1.6% through 2050, far exceeding the nearly stagnant demand trend of the past 15 years.

AI Server Expansion Drives High Demand Scenario

In its April release of the "2026 Annual Energy Outlook," the EIA constructed multiple scenario models for the medium- and long-term impact of data center demand.

Under the high power demand scenario, the EIA assumes that "AI server installed capacity will grow exponentially through 2050" and makes no additional assumptions about improvements in computing efficiency beyond historical trends. This combination of assumptions drives server electricity consumption to peak at 818 billion kilowatt-hours under this scenario.

The EIA also points out that its baseline counterfactual scenario simulates "the operating status of the U.S. and global energy markets under laws and regulations in place as of December 2025," but clearly states that this scenario "should not be regarded as the most likely outcome."

Commercial Building Electricity Intensity to Break Historic Highs

The EIA report shows that in all modeling scenarios, energy consumption in commercial buildings increases faster than in the residential and industrial sectors, a trend closely related to the concentration of data center activity in commercial buildings.

In a statement on Tuesday, the EIA noted that servers alone already account for about 7% of electricity consumption in the commercial sector in 2025.

In both high demand and baseline counterfactual scenarios, the electricity intensity of the commercial sector — measured in kilowatt-hours per square foot — is expected to surpass the historic high of 14.9 kWh/sq ft set in 2003 for the first time in either 2031 or 2032.

Efficiency Gains Difficult to Offset Scale Expansion

Although technological advances are expected to yield some degree of energy efficiency improvement, the EIA’s baseline scenario shows that efficiency dividends will be offset by continuing expansion of installed capacity.

In the baseline counterfactual scenario, the EIA predicts that "after 2040, server efficiency will continue to improve, with average operating power consumption dropping by 10% every three years, exceeding the historical trend in efficiency improvements." However, the report also notes, "continuous growth in server deployments will still push total power consumption higher."

This judgment indicates that, for power infrastructure investors, efficiency improvements are not sufficient to fundamentally change the long-term trend of increasing grid load from data centers. Against the backdrop of an average annual U.S. power demand growth rate of 2.1% over the past five years, data centers will be the main structural driver of electricity demand growth in the coming decades.
