Dirty Data Centers

Data centers are often described as “clean” infrastructure because they don’t produce smokestacks like factories, but they can create several types of environmental and community pollution, especially when large hyperscale facilities are located near residential areas. The impacts typically fall into the five main categories listed below:

1. Air Pollution

Large data centers maintain dozens of diesel and / or natural gas generators to keep servers running. Data centers often start out on public utilities until they outgrow supply and then switch to full generator power. Each data center generator (as seen in the mage) is roughly the same size as the engines that power locomotives.

Pollutants produced by data center generators:

  • Nitrogen oxides (NOx)
  • Particulate matter (PM2.5)
  • Carbon monoxide
  • Volatile organic compounds (VOCs)

Community concerns include:

  • air quality impacts
  • noise pollution
  • cumulative emissions if multiple facilities cluster in one area
data center generators produce pollution 24/7

2. Noise Pollution

Data centers operate 24/7 cooling systems that can produce constant background noise.

Sources of noise:

  • large rooftop chillers
  • evaporative cooling towers
  • massive air intake fans
  • 24/7 generator noise

Noise levels near large facilities can reach 50–85 dB, similar to continuous highway traffic noise can be heard for two miles away which causes significant disruption for nearby residents. Spring Hill High School, Forest Spring Middle School, Wolf Creek Elementary School and hundreds of homes are within the area of impact.

Residents report:

  • Low-frequency humming
  • Constant generator hum
  • Nighttime noise from cooling equipment
  • Humming heard inside their homes

3. Water Consumption

Many modern data centers use evaporative cooling systems, which consume large volumes of water.

Typical usage:

  • 1 to 5 million gallons per day for a large hyperscale campus
  • Water is used to remove heat from servers

Concerns include:

  • Strain on local water supplies
  • Competition with municipal or agricultural use
  • Wastewater discharge from cooling systems
  • Aquaphor depletion and contamination

4. Energy Consumption & Power Infrastructure

Data centers are extremely energy intensive.

Typical data center power demand:

  • 50–150 megawatts for a single large facility

  • Some campuses exceed 500 MW

Impacts may include:

  • New electrical substations

  • Additional high-voltage transmission lines

  • Increased regional power demand

  • Local brownouts as the data center outgrows service
  • Conversion to 24/7 locomotive size generators

5. Heat Discharge

Servers convert nearly all electricity they consume into heat. Handling the heat requires a lot of water and very large cooling equipment that runs 24/7 on the exterior of buildings.

That heat is removed through evaporative cooling towers, large ventilation systems and heat exchangers. Large cooling systems can discharge 7-12MW of heat into the atmosphere.

While heat pollution is usually localized, communities sometimes raise concerns about:

  • Thermal plumes
  • Evaporative pollution
  • Increased ambient heat near large facilities
