Pros and cons
What do you actually get, and what does it cost?
It depends on where you are standing. The deal looks different for the town that hosts the building, the state that writes the tax rules, and the country in a technology race. Pick your level.
This is the level where the debate is most personal, and where both sides have the most receipts. A data center pays taxes like a large industrial property but consumes services like a small office, so host counties can come out well ahead on the budget. It is also the level where every cost that is diffuse nationally becomes concrete: the hum you can hear from your porch, the well that runs dry, the trucks through downtown. Everything below is a named place you can look up.
The property tax money is real, and it funds schools first
The famous case is Loudoun County, Virginia, where data centers pay about $1.2 billion a year and the county cut its property tax rate ten years running.4 But it is not only Loudoun. Fayette County, Georgia turned land paying about $11,000 a year in taxes into a bill projected to pass $40 million a year at build-out, based on current millage rates.32 Mesa, Arizona projects about $156 million over 25 years across city, county and state from one approved Google campus, after $16 million in tax breaks.34
Infrastructure gets built that residents also use
In Botetourt County, Virginia, Google is paying the full cost of the new substations and lines its campus needs, and the county's own materials say the same grid work improves reliability for existing homes and businesses.35 West Des Moines, Iowa has done about $300 million of sewers, water lines, roads and bridges through bonds repaid from Microsoft's property tax revenue rather than by residents, work that opened about 4,500 acres for other development.33
Operators run real community grant programs
Meta reports over $94 million across roughly 3,700 local projects in its host communities. Amazon's InCommunities program reports millions more, county by county, and QTS committed a minimum of $50 million to Dane County, Wisconsin. These are the companies' own numbers, not audited, and they are a fraction of what the buildings cost, but the money reaches named local nonprofits, schools and fire departments.36
The construction trades win, and the credentials last
Electricians' union hours in the DC-area market doubled over a decade to 28 million a year, with data centers at least half of that, and 600 new apprentices in one year.7 A DC-area IBEW apprentice starts around $26 an hour and can reach about $106,000 a year plus benefits on completing the apprenticeship, and Northern Virginia Community College now runs a dedicated data center operations credential program.37
On average, spreading grid costs can push rates down, not up
A study by EPRI, the electric utility industry's research institute, estimates that state residential electric rates in 2024 would have averaged about 6 percent higher without the data center growth of 2019 to 2024, because big new customers spread the grid's fixed costs across more sales.38 Industry-funded, and a national average, not a promise: in the tight mid-Atlantic market, standby costs pushed bills up instead, which is documented by the grid's own watchdog in the state tab.17
The noise is real, documented, and constant
Chandler, Arizona residents have reported a constant hum since 2014, and the city now requires developers to fund a noise-complaint liaison. Prince William County HOAs formally complained of round-the-clock industrial noise, and the county added enforcement for steady tonal noise effective May 2026. And when a Loudoun County campus lost utility power in July 2026, a day of diesel backup generators produced a flood of resident complaints about noise and fumes.39
Water use can crowd a town's supply
In The Dalles, Oregon, Google's share of the city's water grew from 12 percent in 2012 to about a third by 2024, roughly a million gallons a day.40 A projection by the sustainability nonprofit Ceres has Phoenix-area data center cooling water growing as much as tenfold, from about 385 million to 3.8 billion gallons a year; the environmental outlet reporting it notes the estimate is a worst case that may run high, and the basin is already short of water either way.41 In Newton County, Georgia, homeowners near Meta's facility report wells running dry since construction and have sued; the facility draws about a tenth of county water use, and the county projects a supply deficit by 2030. A lawsuit is allegations, not a verdict, but the wells and the deficit projection are on the record.42
Land use fights are about farmland, viewsheds, and consent
Prince William County's Digital Gateway rezoned about 2,133 acres of rural land for more than 20 million square feet of data centers, approved 4 to 3 with one abstention after a 27-hour public hearing. A Virginia appeals court later voided the rezoning because public-notice requirements were not met.43
Construction is loud, heavy, and years long
Saline, Michigan residents report gravel-truck traffic rattling downtown for the Oracle and OpenAI build; Spartanburg, South Carolina residents report construction noise as early as 1 a.m.46 The construction phase is also where most of the economic benefit is, which is the trade at the heart of this debate.22
Diesel backup generators are lightly policed
Every data center keeps a fleet of diesel generators for outages. Operators largely decide for themselves what counts as emergency use and self-report their emissions, with limited outside oversight, and environmental groups have petitioned regulators over the health effects of diesel exhaust near homes.44
Few permanent jobs, and no promise for nearby home values
Virginia's legislative auditor found a typical 250,000-square-foot data center employs about 50 people, roughly half contractors.22 The best national study measured 100 to 200 permanent jobs per county over a decade.6 The realtors' association's 2026 report found no single effect on nearby home values: 25 percent of agents reported a positive effect, 22 percent negative, and residents' top worries were energy costs and water, not prices.45
Whether the deal is good for a community mostly comes down to three things you can check before the vote: does the operator pay for its own grid and water infrastructure, does the county tax the building at full industrial rates or give them away, and are noise and siting standards binding before the permit is issued rather than promised after. The places with the receipts on the pro side did those three things. The places in the cons column mostly did not.
The state writes the two rule books that decide who wins: the tax code and the utility rules. The remarkable thing at this level is that the best evidence on both sides often comes from the same document. Virginia's legislative auditor produced the strongest pro numbers and the strongest con numbers in the same body of work, and Georgia's utility regulator appears in both columns below. That is not a contradiction. It is what an honest ledger looks like.
The jobs and economic activity are measured, not modeled
Virginia's nonpartisan legislative auditor credits data centers with 74,000 jobs, $5.5 billion in annual wages, and $9.1 billion a year in economic activity, and found they made up 84 percent of all capital investment the state's economic development agency tracked from 2022 to 2024, with $24 billion in fiscal 2023 alone.22
As tax breaks go, this one performs better than the rest
The same auditor measured a decade of the sales tax exemption and found 48 cents of new state revenue per dollar given up, nearly three times the 17-cent average of Virginia's other exemptions, and a 2026 state incentive evaluation ranked it the state's second-best incentive at $6.10 of labor income per exempted dollar.22 28 Losing money, but losing less than everything else in the drawer, and generating real paychecks along the way.
Big users can be made to push residential bills down
Georgia's utility regulator approved a fuel and storm-cost deal that its coverage projects saving the typical household about $50 a year, roughly $285 million a year across customers, with large energy users' growth helping carry the fixed costs. The structure matters: when regulators make giant customers pay in more than they cost, everyone else's share of the grid shrinks.48
States hosting the buildout are hosting the growth engine
Analysts applying federal GDP data found data center and related high-tech spending drove roughly 80 percent of the rise in final private domestic demand in the first half of 2025. Across the full year consumption was still the bigger engine, with AI capital spending second, but states that host the clusters capture the construction wages, utility investment and property tax of the biggest investment story in the country.49
The exemptions blow past every forecast
Ohio's data center exemption cost more than $1.5 billion in 2025 against an official forecast of $136 million, more than eleven times the projection, on the Department of Taxation's own numbers.50 20 Most of these exemptions have no caps and no annual vote, so the cost grows on autopilot as the buildout grows.
Even the best-case state is losing real money
Virginia, the state with the best measured return, gave up about $1 billion in fiscal 2024 alone, up from $685 million the year before, with cumulative exemptions of $2.7 billion over the decade, more than half of everything the state spent on economic incentives in that period.51 The 48-cent return means the flip never came: ten years of income taxes, corporate taxes and non-exempt sales taxes were already counted, and the state still got back less than half.
The money concentrates in very few hands
Indiana's newly required disclosures show $655 million in exemptions since 2019, with over 93 percent of the most recent two years' total going to a single company, Amazon.52
Ratepayers are carrying measurable costs
The grid watchdog for 13 states attributed $6.3 billion, 38 percent, of one capacity auction's cost to data centers, and 46 percent of $63.6 billion across the last four auctions.17 New Jersey households saw increases of 17 to 20 percent take effect in June 2025.27 And Georgia's commission staff estimate the current rate structure could raise residential fuel costs 5 to 11 percent by 2028 if large users' costs keep spilling over.48
Demand could outrun what the state can build
Virginia's auditor projects that unconstrained data center growth would double the state's electricity needs within ten years, requiring solar buildout at twice the record pace plus more offshore wind than every secured site combined.22
States are already legislating for the risks
Texas passed authority to force loads over 75 megawatts to curtail during grid emergencies, a marked policy shift in the most buildout-friendly state in the country.53 During a drought year, projects in Georgia and Arizona were found drawing more water than disclosed or authorized.54 And after more than 7,000 public comments, Ohio scrapped a proposed streamlined statewide wastewater permit for data centers, keeping case-by-case review of every project instead.54 Laws and rulings like these are what it looks like when states stop taking the industry's word for it.
The state-level question is not really for or against. Virginia's own auditor produced both columns' best numbers, which tells you the honest fight is about terms: caps on the exemptions, annual disclosure of what they cost, rate structures that make giant users pay their own way, and reliability and water rules written before the buildings arrive rather than after. States that set terms keep the upside. States that do not are discovering the costs from their own auditors, twelve-fold forecast misses at a time.
At the national level the debate stops being about a county budget and becomes about strategy. The pro case is that these buildings are where America's chip advantage becomes usable capability in a technology race. The con case is that the same buildout is straining the grid, the climate ledger, and, by the account of the world's central bankers, possibly the financial system. Both cases rest on the same underlying fact: the scale is enormous.
America leads the AI race in exactly one pillar, and this is it
An independent research group that measures global computing puts about 75 percent of the world's AI supercomputer capacity in the United States against roughly 15 percent in China, measured by where the hardware physically sits.47 Even pro-buildout advocates frame it starkly: of the four pillars of AI strength, energy, compute, talent and adoption, compute is the one America still clearly leads.30 A chip only becomes capability once it is racked in a powered building; the data center is where the advantage gets converted.
Security analysts want frontier AI on US soil
Brookings analysts argue that where frontier AI facilities are built is now a strategic choice, not a commercial one, and that building them overseas creates national security exposure that ordinary siting decisions do not capture.30
Federal policy across administrations treats this as critical infrastructure
The July 2025 national AI plan and its companion executive order put data centers over 100 megawatts on accelerated permitting, opened federal land, and named four federal sites for public-private AI energy development.2 3 Whatever one thinks of the policy, the United States government has formally decided this infrastructure is strategic.
The buildout is the current growth engine of the US economy
Analysts applying federal GDP data attribute roughly 80 percent of the rise in first-half 2025 private domestic demand to data center and related high-tech spending; over the full year, consumption still led and AI capital spending came second.49 The industry's own commissioned study models 5.5 million supported jobs and over $200 billion in annual tax contributions; treat that one with its label on, industry-funded and modeled rather than counted.31
The bills reached tens of millions of households
The capacity price spike in the 13-state PJM region reached electric bills for roughly 65 to 67 million people, depending on which count of the region is used, with reported average increases around 30 percent, and the grid's independent watchdog attributes nearly half of four auctions' $63.6 billion in charges to data center demand.59 17
Emissions are rising to meet the demand
The International Energy Agency projects data center emissions peaking around 320 million tonnes of CO2 by 2030, under 1 percent of the global total, but rising, and specifically projects US power-sector emissions increasing in 2026 as natural gas, currently the largest single power source for US data centers, expands to meet the load.55
The water footprint is national, and mostly invisible
The federal energy laboratory puts US data centers' direct cooling water at about 17 billion gallons in 2023, heading for 38 to 73 billion by 2028, plus roughly 211 billion gallons a year consumed indirectly at the power plants that feed them. The indirect share rarely appears in any company's disclosure.56
The grid's own referee calls this a top reliability risk
The federally certified reliability regulator raised its ten-year peak demand projection by 224 gigawatts, 69 percent, with data centers the largest single contributor, found 13 of 23 grid regions at elevated or high risk, and has issued formal alerts after events where sudden data center disconnections disturbed grid frequency.57
The world's central bankers are officially nervous
The five largest technology companies plan over $1 trillion in AI spending across 2025 and 2026, increasingly financed with debt and private credit. The Bank for International Settlements, the central banks' own bank, has formally warned that some of the financing structures may mask leverage and that the system is exposed if the spending slows.58 The IMF is more measured, judging the financial stability impact modest so far but worth monitoring.58 Either way, the institutions whose job is worrying about the next crisis are now watching this buildout by name.
The growth engine is also the concentration risk
The strongest federal pro and the strongest federal con are the same sentence: the buildout is enormous. If AI delivers what its builders expect, this is the next economy's grid, bought early, with America holding the lead. If it disappoints, the country will have concentrated its growth statistics, its grid planning, and a trillion dollars of increasingly debt-financed spending on one bet. That is why the serious argument at the national level is rarely build-or-do-not-build. It is about pace, terms, and who is left holding which risk if the bet sours.
