The internet is not a cloud. It has a body — concrete, steel, copper, and water. Every message you send, every song you stream, every AI model you query runs through a physical building full of servers. These buildings are called data centers. They are the infrastructure on which the digital world depends. And they are not distributed evenly, cheaply, or without cost.
This page is a factual resource. It does not argue for or against data centers. It maps where they are, what they consume, how communities have responded, and what may change if the technology they're built for becomes more efficient — or obsolete.
A data center is a building — often a warehouse-scale facility — filled with servers, networking equipment, and cooling systems. They store and process digital information. Some are hyperscale (run by Amazon, Google, Microsoft, or Meta), some are colocation facilities (multiple companies rent space), and some are enterprise (built by a single company for its own use).
As of 2026, the United States has approximately 5,400 data centers. Northern Virginia alone — known as "Data Center Alley" — houses over 200 facilities and carries more than 70% of global internet traffic. A single modern hyperscale data center can consume as much electricity as 100,000 homes.
Loudoun County, Virginia, is the densest concentration of data centers on earth. Approximately 30 million square feet of data center space — the equivalent of ten Nashville downtowns — sits in a county of 440,000 people. For decades, the county offered generous tax incentives that made it the default location for internet infrastructure.
In March 2025, the Loudoun County Board of Supervisors eliminated by-right development for data centers. New facilities now require a special exception — a legislative review process with mandatory public hearings. The county's goal, in its own language, is "balancing the economic advantages of data centers with the concerns of its residents."
Fairfax County and Prince William County, adjacent to Loudoun, have also adopted new size limits, noise study requirements, and residential setback rules. Multiple projects have been halted or withdrawn due to community opposition.
Data centers use approximately 7.4% of Arizona's total electricity. New facilities have concentrated in the Phoenix metro area, where water is already scarce and summer temperatures push cooling demands to extremes. Arizona Public Service reported 7,000 megawatts of data center interconnection requests in its pipeline as of 2024 — enough to power over a million homes at peak.
Data centers consume 11.4% of Oregon's electricity — the highest share of any state. In June 2026, Governor Kotek signed House Bill 4084, barring new data centers from accessing Oregon's Enterprise Zones property tax incentive program. The moratorium gives a state advisory committee time to study environmental, energy, and economic impacts before the 2027 legislative session.
The City of Hillsboro has also opened work sessions to evaluate land use changes for data centers, including potential requirements for environmental and economic development assessments.
In September 2025, Jerome Township trustees imposed a nine-month moratorium on new data center construction. Residents had raised concerns about noise, energy use, and the fact that existing facilities received tax breaks negotiated by county officials — meaning the township itself saw little commercial tax revenue.
According to Data Center Watch's Q3–Q4 2025 report, community opposition to data centers is now active in 42 U.S. states. Hundreds of local groups have formed. Projects representing an estimated $152 billion in potential investment were blocked or delayed by local opposition during 2025. What began as scattered resident complaints has consolidated into a national political force.
Modern data centers can consume 4.5 million gallons of water per day — equivalent to a small city's daily usage. Bloomberg News analyzed data from the World Resources Institute and found that more than 160 new AI-focused data centers have opened in the past three years in regions already facing high competition for scarce water resources. The water is used primarily for cooling: server rooms generate enormous heat, and evaporative cooling systems pull water from local supplies.
In drought-prone regions of the American West, this has created direct competition between data centers and residential water supplies. When a community in a water-stressed area is asked to choose between drinking water and server cooling, the result is predictable: organized opposition.
Data centers and data transmission networks have a larger carbon footprint than the airline industry and account for more than 1% of total greenhouse gas emissions nationally, according to the International Energy Agency.
In Washington County, Oregon, residents report residential electricity rates rising by nearly 50% while data centers pay less than half the rate per kilowatt-hour that households do. New substations are built to serve data centers, and the costs are spread across all ratepayers. One Oregon organizer described the dynamic bluntly: "families are subsidizing corporate infrastructure."
Data centers are typically windowless concrete buildings surrounded by generators and cooling equipment. They create persistent low-frequency noise — the hum of cooling fans and backup generators running continuously. When built adjacent to residential neighborhoods, they become a 24-hour presence. Residents of Briarfield Estates in Loudoun County report the hum as a constant, inescapable feature of daily life.
Heat island effects have also been documented: large facilities can warm surrounding land by up to 16 degrees Fahrenheit, altering local microclimates.
The following is a partial list of communities where data center development has been challenged, paused, or reversed:
The same questions recur across every contested development: Who decided this should be built here? What are the long-term costs, and who pays them? How much water and power does it use? Is the tax revenue worth what we're giving up? And — increasingly — will this building still be needed in ten years?
Data centers are built on 30-year bonds, designed for a specific technical architecture: large clusters of power-hungry GPUs running transformer-based models at scale. This architecture is not guaranteed to remain dominant.
Several forces point toward dramatic efficiency gains over the next three to ten years:
The industry is not blind to this. As of mid-2026, approximately half of the data center projects planned for the year have been canceled or delayed. Some of this is community opposition. Some is financial: investors recognize that building for today's compute model carries risk when the model is evolving rapidly.
This page describes physical infrastructure and community response. It does not argue that data centers are good or bad. They are infrastructure — necessary for the digital services people rely on. The question is whether we are building them thoughtfully: in the right places, at the right scale, with community consent, and with an honest accounting of long-term costs versus the risk that the technology they serve will outgrow them.
