Facts first. Then the debate.
What data centers really use, cost and change — with sources for every number.
An independent, non-partisan resource. Facts are sourced and dated. Opinion is clearly labeled. Debate is moderated and always shows both sides.
Each issue shows the strongest sourced fact on both sides.
Electricity & power bills
Supporters point to
$7–9/mo saved
An Indiana utility (NIPSCO) estimates its data center agreements could eventually lower residential bills — though Berkeley Lab warns savings aren’t guaranteed.

Critics point to
+8% by 2030
Estimated average U.S. household bill increase from data centers and crypto mining — over 25% in central and northern Virginia.

Water
Supporters point to
~39× less
A closed-loop data center uses about 2.9 million gallons a year — roughly 1/39th of a typical 18-hole golf course.

Critics point to
3–5M gal/day
A single hyperscale site using evaporative cooling can use this much — and not every new build is closed-loop.

Jobs & taxes
Supporters point to
74,000 jobs
Virginia’s data center industry supports about 74,000 jobs and drew over $24 billion of investment in FY2023.
Source: Virginia JLARC, 2024–2025
Critics point to
$1B in one year
Virginia’s data center sales tax exemption cost about $1 billion in FY2024 alone. Most industry jobs are temporary construction work.

Noise
Supporters point to
50–65 dB
At 100 feet, a new data center is about as loud as a dishwasher. At a quarter mile it fades to quiet-suburb background.

Critics point to
Constant hum
Residents near sites in Virginia and Arizona report a 24/7 low-frequency drone that standard decibel meters struggle to measure.

Water use per year, typical
Millions of gallons. Closed-loop data center vs. common land uses.
100-acre irrigated cornfield
Caveat: closed-loop cooling trades some water for slightly higher energy use, and not every new build uses it. Sources: Microsoft Mount Pleasant (Daily Reporter), GCSAA, California Avocado Commission, Texas Tech.
How loud is it?
Decibels by distance. +10 dB sounds about twice as loud.
Data center at 1 mile is usually below ambient background noise.
