A plain walk through the questions people ask most, from the meter on your house to the budget at the county courthouse.
A data center is a secure building full of computers that store and move information. When you check a bank balance, a hospital pulls up a chart, a dispatcher answers 911, or a forecaster updates the radar, the work happens inside one of these facilities.
They are less a mystery box and more like a utility: the quiet infrastructure that keeps modern life running, the way water towers and substations do.
In 2023, data centers accounted for 4.4% of all electricity used in the United States.2 That is a real load, and it comes with real investment: operators typically help pay for the new plants, substations, and transmission lines built to serve them.
A study from a federal laboratory found the opposite effect. Electricity rates would be roughly 6% higher today without the data centers built between 2019 and 2024, because large customers spread the fixed cost of the grid across more users.3
Sites are usually chosen where the grid is already strong. Regional utilities such as Georgia Power, Duke Energy, and Florida Power & Light then add substations and lines to serve them, and those upgrades make service more reliable for every household on the system.19 Many operators also sign long-term contracts that finance new solar farms across Georgia, Florida, and the Carolinas.
They are insurance, not a power source. Backup generators run about 100 hours a year, mostly for required testing, and must meet strict EPA emissions rules.4
Every U.S. data center combined used about 17 billion gallons in 2023. Spread across the country, that equals roughly 0.02% of daily freshwater withdrawals.5
Newer facilities fill their cooling systems once and recirculate the same water for years. Microsoft reports its newest AI data centers use about as much water in a year as one restaurant.6 Google, Meta, and Microsoft have each pledged to return more water than they consume by 2030.7
Where older open-loop designs are still used, discharged water has to pass through the same municipal treatment required of any hospital or factory. Releasing untreated water into local streams is not allowed.
Typical sound at the property line8

Less light at night than older designs10
Modern sites are engineered to sit around the level of a normal conversation or a running dishwasher at the fence line. Sound barriers and variable-speed fans trim another 5 to 15 decibels, and a growing number of facilities use immersion cooling, which needs no fans at all.
Shielded fixtures that point down, paired with automatic dimming, reduce nighttime light by 80 to 90% compared with older builds, which means far less glow on the horizon.
U.S. jobs supported nationwide1
Construction jobs on a typical project
Local jobs supported per direct job1
A typical project employs 1,000 to 2,000 people during construction, then keeps 100 to 200 permanent staff on site once it opens. Those roles include electricians, HVAC technicians, network and IT specialists, security officers, and facility managers.
Many of these positions are filled through partnerships with nearby technical and community colleges that train local residents for exactly these careers.20
Each direct job supports about four and a half more in the surrounding economy: the diner down the road, the electrical contractor, the landscaping crew, the parts supplier. That spending lasts well beyond the facility's own payroll.
In 2024 the industry paid $204 billion in federal, state, and local taxes and added $927 billion to U.S. GDP.1 Unlike a one-time construction project, a data center pays property tax year after year, often for decades, which gives schools, roads, and first responders a steady source of funding.
No place hosts more data centers than Loudoun. They occupy just 4% of the county's commercial land yet supply 38% of its general fund, an expected $1.3 billion in fiscal 2027. Without that revenue, a 2026 analysis estimates the average homeowner would owe about $5,800 more in property tax each year.11

Beyond taxes, operators are putting money directly into the places they build. Microsoft has backed more than 75 water and wastewater projects. Meta's community grants included $5.6 million in New Albany, Ohio. Amazon's campus in Montgomery County, Missouri brings new roads, new water lines, and more than 400 jobs.14 Google's fund aims to help over a million Americans build AI skills.
Affordable land, strong fiber networks, and a dependable power grid have turned the region into a national hub.

At the high end, a single approved campus in Pittsylvania County, Virginia represents a $100 billion investment and about 2,000 permanent jobs, one of the largest private investments any U.S. host community has seen.16 Most projects in the region are smaller, but the pattern holds: construction work now, steady jobs and tax revenue for years after.
Georgia and the Carolinas are also moving toward carbon-free generation, and Southeast facilities are leaning into closed-loop and water-free cooling.
