The $25 Billion Bill: The Hidden Environmental Cost of America's Data Center Boom

A $25 Billion Hidden Tax on America

Data centers cost the United States about $25 billion in pollution and health costs last year alone, according to an analysis by Carnegie Mellon economist Nicholas Muller, who examined data from roughly 2,800 data centers operating across the U.S. in 2025.

Drawing on figures from S&P Global Insights, the U.S. Department of Energy, and the Environmental Protection Agency, Muller estimated the monetary impact of the air pollution and greenhouse gas emissions these facilities generate. His warning is stark: as more data centers are built and energy demand climbs, pollution and health-related costs could rise by up to 85% in the near term.

Powering AI at the Public's Expense

Muller's analysis found that in 2025, data centers consumed about 5% of the nation's total electricity output — much of it to power AI activities. That share is only set to grow. According to International Energy Agency estimates, data centers worldwide have increased their energy consumption by 12% every year over the last five years, with AI driving the surge.

The Damage Is Concentrated — and Lopsided

The environmental costs varied dramatically by location. In some states, the damage from air pollution actually outweighed the data centers' contribution to regional GDP. Just ten states produced 70% of all pollution and health-related costs in 2025.

In Virginia and Texas alone, combined environmental costs made up 30% of the nation's total monetary damage from data centers — both states also host the most data centers operating or under construction, according to Aterio. Unlike Texas, Virginia is one of 11 states that have proposed restrictive legislation on further data center development.

A Growing Legislative Backlash

At least 11 states have proposed legislation since late 2025 to "restrict or ban data center development," Axios reports. Maine lawmakers passed an 18-month moratorium on large data centers in April, but Gov. Janet Mills vetoed the bill, and legislators failed to override the veto.

In Mississippi, the NAACP filed a lawsuit accusing xAI, Elon Musk's AI company, of operating "dirty turbines that emit pollution and known carcinogens" in violation of the Clean Air Act at a power plant used to run data centers near Memphis and Southaven, The Guardian reports.

Public Opinion Has Turned

The mood has shifted sharply. In Virginia, the share of voters comfortable with new data center construction plunged to 35% in March, down from 69% in 2023, according to a Washington Post poll. A March Pew Research Center survey found Americans hold mostly negative views, with pluralities considering data centers "mostly bad" for the environment, home energy costs, and quality of life for nearby residents.

The boom that promises to power our digital future is quietly handing the public a $25 billion bill — paid in polluted air, higher energy costs, and damaged health.
