In Northern Virginia—the world’s largest data center hub—an analysis of 132 facilities found they are backed by more than 10,500 industrial diesel generators.

Although intended for emergency backup power, these units undergo regular maintenance testing that discharges hazardous emissions, such as fine soot and nitrogen oxides.

Research from Virginia Commonwealth University and the University of Washington indicates that running these generators for under an hour each week generates air pollution equivalent to five large gas-fired power plants, aggravating respiratory ailments and leading to premature deaths.

Similar health and air quality concerns are emerging across states like Maryland, Delaware, Utah, and Oregon as server infrastructure expands.

While regulatory bodies and industry operators state that facilities comply with environmental limits, residents frequently report visible soot, black smoke, and acute irritation.

The issue is further compounded as grid operators receive authorization to utilize backup diesel capacity to meet peak electrical grid demands.

Data centers are large because they house thousands of server racks, power supplies, and cooling systems for internet and AI services—not to store or “steal” water.
​While evaporative-cooled data centers do consume water, all U.S. data centers combined account for less than 0.5% of national freshwater use (compared to agriculture, which uses over 75%). Furthermore, tech companies are rapidly switching to dry cooling, closed-loop liquid systems, and recycled wastewater to eliminate direct water consumption entirely.

Environmental activist Erin Brockovich has highlighted community reports of wildlife disappearing around some large data-center developments in the United States. Residents have reportedly contacted her with concerns about fewer birds, disappearing wildlife and dead animals, including concerns involving areas used by bald eagles. These reports are being collected through her data-center tracking initiative.

Brockovich has linked residents’ concerns to the broader environmental footprint of hyperscale data centers, including land clearing, tree removal, constant cooling-system noise, heavy water use and construction of supporting power infrastructure. However, these potential impacts can vary significantly from one project to another and require site-specific environmental studies.

Importantly, the reported wildlife impacts are community observations and allegations, not established scientific evidence that data centers are causing wildlife populations or migration patterns to change.

Lisäksi jenkeissä kukaan ei halua investoida siirtoverkkoon, koska se ei tuota tarpeeksi, eli Suomen siirtoverkko on vahva, verrattuna jenkkeihin, Hollantiin, tai vaikka Ruotsiin.

While the heat was more concentrated in the Midwest during the Dust Bowl, all 48 lower states experienced excessive heat this summer — at least one degree Fahrenheit warmer than the 20th century average.

And instead of focusing on ways to fight the effects of climate change, much of the country is moving in the opposite direction. The Trump administration is closely aligned with the fossil fuel industry and is actively seeking to reopen coal-burning plants. AI data centers powered by gas generators are compounding a major uptick in greenhouse gas emissions.

The result is a country literally on fire, while suffering the second-worst July drought conditions on record for the contiguous US, according to Yale Climate Connections. Per the US Drought Monitor, a whopping 71 percent of the contiguous US experienced abnormal dryness or drought during the first week of August, coming on top of billions of dollars in direct damages during the first half of 2026.

Meanwhile, major wildfires continue to burn across both the US and Canada, exposing millions to dangerous levels of air pollution and causing an estimated 4,000 premature deaths across the continent within a single week last month, according to The Economist.

“This may be one of the coolest years we’re gonna experience for the rest of our lives,” Masters told the AP.

To give humanity a fighting chance we need to “stop burning so many fossil fuels,” he added. “We also need to be spending money to adapt to the new climate that we’ve put in place.”

Where the claim is EXAGGERATED (The National Level):
​Minor Share of Total Water: All U.S. data centers combined consume less than 0.5% of national freshwater.
​The Real Consumers: By comparison, irrigated agriculture (mostly growing feed crops like alfalfa and hay) consumes over 75% of water in the American West, and residential lawn watering uses over 10 times more water annually than every data center in the country.

Because water availability has become a bottleneck for local approvals, tech companies are actively phasing out traditional water-evaporating cooling towers.

Summary
​Data centers aren’t “killing life,” but they do consume substantial resources in specific towns where they are built. The solution isn’t hyperbole—it’s enforcing strict local zoning that mandates zero-water dry cooling and clean energy grid connections.

Data centers are not toxic waste dumps. At their core, they are massive, highly secure warehouses filled with computer servers, networking equipment, and heat exchangers.

​No direct toxic runoff: Unlike chemical plants or industrial manufacturing, data centers do not generate toxic chemical effluent or pollute surrounding soil during normal operation.
​Primary outputs: Their main physical outputs are electricity consumption, mild heat, and noise (from large cooling fans).

Local impact: The main environmental footprint is indirect—driven by where their electricity comes from (e.g., fossil fuel power plants vs. clean energy) and how much land they occupy.

The cooling tower that uses evaporation is just one heat transfer method. There are also several other heat transfer methods that do bot use water consuming cooling towers.

Dry Air Cooling (Air-Cooled Chillers): Uses fans to blow ambient outdoor air across finned fluid coils (like a giant car radiator).

Geothermal & Deep Water Cooling (SWAC): Passes internal server fluid through titanium heat exchangers submerged in naturally cold ocean, lake, or ground loops.

Adiabatic Hybrid Systems: Runs as a 100% dry air cooler for most of the year, using only light water misting on extreme high-heat days.

District Heating Heat Recovery: Captures warm server fluid (30^\circ\text{C}–45^\circ\text{C}) and uses commercial heat pumps to boost its temperature (70^\circ\text{C}–90^\circ\text{C}+) to deliver zero-water waste heat directly into municipal heating networks.

“Almost every watt of power that goes into a computer data center eventually ends up as heat.”

True.

“My point is these installations are very simple and very environmentally friendly when compared to the steel mills, chemical plants, and ship yards”

I would agree with this.

“They are jumbo electric loads but utilities can engineer solutions to serve them without impacting other customer’s electric service.”
