The Data Center Debate

Non-partisan. Every claim linked to its source.

The data center debate, from both hills.

Data centers are being built faster than power plants, and the fight over who pays, who benefits, and who gets asked is playing out in county meetings across the country. This site lays out what each side actually says, the evidence behind it, and who paid for that evidence. Then you decide.

The one rule of this site

Do not take anyone's word for it, including ours. Every number here links to the document it came from, and every document is labeled with who wrote it and who paid for it. A study funded by the industry's lobbying group and a study from a state's nonpartisan auditor are both worth reading. They are not worth the same weight, and you should know which is which before you repeat either one.

How we keep this even-handed

What both sides already agree on

  • 192 TWh. Electricity US data centers used in 2024, about 4.7% of the national total.1
  • 649 TWh by 2030 is the best estimate, with a range of 578 to 782.1
  • 74,000 jobs a year in Virginia, mostly during initial construction.22
  • Costs "will likely increase" for all electricity customers, per the same study.22

The debate is not about these facts. It is about what to do about them. Read the full table

The case against
  1. Regular families are paying part of the bill, and the deals are kept secret so nobody can check.
  2. The grid's own watchdog blames data centers for billions in higher costs.
  3. The jobs do not show up, and states are paying enormous amounts for the few that do.
  4. Virginia studied this honestly, and the permanent half of the verdict is bad.
  5. The water use is real and largely hidden, and the pollution lands on the same neighborhoods it always does.
  6. Communities across the country are saying no, and the industry's own tracker proves it.
  7. They are enormous, they hum all night, and they change what a place is.

The case for
  1. These buildings get built no matter what. The only question is where.
  2. The tax money is real, it is already proven, and it is lowering people's bills right now.
  3. The jobs argument, told honestly. And the construction workers are not a footnote.
  4. The cost-sharing problem is real, it has a known fix, and the fix is being installed.
  5. The grid has far more room than people think, if the load will bend.
  6. This industry has actually gotten more efficient before, and the scary forecasts have been wrong before.
  7. The noise and the looks are real complaints with engineering answers, and the answers are being written into law.

Virginia federal lawmakers pile on data center bills as Fauquier plans key vote

Sen. Mark Warner and Rep. Suhas Subramanyam rolled out a slate of federal bills including the Data Center Fair Share Act, which would push states to adopt tariffs so data centers cover their own energy infrastructure or forfeit federal highway funds. The push comes as Fauquier County's Planning Commission is set to review the 900 MW, 2.2 million square foot Remington Innovation Campus on September 17.

Virginia Mercury Whether the bills have Republican co-sponsors and any Senate committee movement, and whether the highway-funds enforcement mechanism is likely to survive legislative markup.

Lima, Ohio council passes unanimous 18-month data center moratorium

Lima City Council approved an 18-month moratorium on new data center construction and on new city water requests from outside municipalities, so that staff can study siting, water and power standards. Mayor Sharetta Smith cited Ohio's rapid data center growth. The moratorium does not affect the existing water agreement for a Google data center under development in American Township.

San Francisco supervisors introduce 45-day data center moratorium

Supervisor Shamann Walton, joined by Connie Chan, Chyanne Chen and Jackie Fielder, introduced a 45-day urgency ordinance to freeze new data center approvals, with an eye toward a permanent citywide ban. Under state law the interim ordinance needs a four-fifths vote and can be extended to nearly two years if the planning commission finds a public-welfare threat. The proposal follows expansion plans at NOVVA's 400 Paul Avenue project in Bayview.

Hoodline Whether the four-fifths supermajority is secured for the interim ordinance and how the moratorium treats projects that already have entitlements.

Hayward City Council directs staff to draft data center ban

The Hayward City Council took up a legislative referral from Mayor Mark Salinas and two colleagues directing staff to begin amending the zoning code to prohibit new data centers, following pushback against an approved 76.6-megawatt facility with 28 diesel backup generators. Hayward had already amended its code in April 2026 to require major conditional use permits for such projects.

City of Hayward Whether the referral produces an actual ordinance and how it treats data centers that already hold permits, including the 76.6 MW project.

Loudoun County supervisors advance 12-month pause on new data center applications

In a 7-1-1 vote, the Loudoun County Board of Supervisors directed staff to draft a resolution pausing new data center applications for up to 12 months while it develops new rules. Board Chair Phyllis Randall framed the pause as temporary; the county attorney said an indefinite moratorium would likely be illegal. A final vote is expected in October.

Data Center Dynamics Whether the final October vote adopts the 12-month pause, whether by-right grandfathering is preserved, and how many pending applications would be captured.

Virginia DEQ orders Microsoft to pay about $2.5 million over Leesburg generator emissions

Virginia's Department of Environmental Quality issued a consent order requiring Microsoft to pay roughly $2.5 million over air-quality violations at its Compass Creek Parkway data center in Leesburg during a June 27 to July 1, 2025 substation outage. The agency says the site exceeded permitted limits for nitrogen oxides, particulate matter and volatile organic compounds; Microsoft says it has invested about $31 million in reliability upgrades. The order is subject to public comment through October 14.

NewsBreak / WJLA Whether this is the largest DEQ air-quality penalty on record, whether the consent order becomes final after public comment, and how backup generator runtime rules apply during grid outages.
