After Dulles, the suburbs begin to lose their gentleness as you drive west from Washington. The strip malls get smaller. The trees return. Then, out of nowhere, the warehouses show up. They are long, windowless, fenced, and arranged like massive shoeboxes that were dropped by something that didn’t give a damn where they ended up. The hum you hear in Loudoun County is the result of about 200 data centers performing the unseen labor that keeps your AI chatbot responding and your inbox loading. The hum is initially faint but eventually becomes constant.
It’s difficult to ignore how peculiar the scenery has become. Ten years ago, cornfields were server farms. Before anyone truly understood what it would be like to live next to five square kilometers of warehouses, locals will tell you that the change took place covertly, in the language of zoning hearings and tax incentives. On paper, the trade-off appeared clear. Tax money came in. Jobs came, but not as many as anticipated. Subsequently, bills for electricity, water, and air that the locals claim no longer smells quite right began to come in.

Speaking with people in communities like Haymarket and Gainesville gives the impression that something has recently gone wrong. Perhaps it was the diesel generators, which started up more frequently when the grid was having trouble. Perhaps it was the knowledge that one large facility can consume as much water annually as thirty thousand households. Perhaps Julie Bolthouse of the Piedmont Environmental Council made the observation that Virginia’s 285 million square feet of authorized or pending data center space equates to about 1,500 Walmart Supercenters. Conversations are usually cut off by that figure.
The figures themselves are overwhelming. The only industry in Virginia where demand is still rising is data centers, which accounted for 21% of Dominion Energy’s electricity sales in 2022. According to projections, if the build-out continues unchecked, power consumption could increase by 183% by 2040. The increase would be a meager 15% without it. The entire fight is depicted by those two figures side by side.
The collision of histories is what sets Loudoun’s case apart. Proposed gigawatt-scale developments are located a few miles away from the Wilderness Battlefield, Manassas, and the Civil War site that took generations to protect. Lawsuits have been filed by the American Battlefield Trust. The Virginia Data Center Reform Coalition, which was formed by more than 25 organizations, is advocating for transparency that lawmakers had previously seemed hesitant to provide.
Whether any of this slows the momentum is still up in the air. Big Tech has lobbyists, money, and an AI race that no one in Washington wants to lose. There are lawsuits, signs on the lawn, and the hum among the locals. Observing the cranes ascend along Route 7 gives the impression that the nation is making a decision here without fully acknowledging it: how much landscape, water, and air quality is the digital future worth?
By 2050, Virginia pledged to use only renewable energy sources. Additionally, the warehouses that might make that promise mathematically impossible are being approved by the state. There must be a compromise. America learns what in Loudoun County.
