Few things spark a neighbourhood argument quite like the arrival of a data centre. The promise of high-tech jobs and digital infrastructure clashes with fears about noise, water use, and property values — and across the United States, locals are increasingly saying no.

The trade-off

For a network operator like Propagate Networks, data centre buildout means faster peering and lower latency — but community resistance can stall projects for years. The gap between tech ambition and local reality is widening.

Who are the big 5 in data centers?

Five companies dominate the colocation space by revenue and square footage. Data Centre Magazine’s 2025 Top 100 ranking places Equinix, Digital Realty, NTT, CyrusOne, and QTS at the top. These firms lease rack space and power to thousands of businesses, from startups to Fortune 500 enterprises.

What are the big 3 data centers?

  • AWS (Amazon Web Services) — the largest cloud provider by revenue, ranked first in the industry for hyperscale operations (Data Centre Magazine)
  • Microsoft Azure — a close second, with aggressive global expansion
  • Google Cloud — third, with a focus on AI workload infrastructure

These three hyperscalers build and operate their own data centres, but they also lease space from colocation providers at scale.

Which company owns the largest data center?

The single largest data centre facility by floor space is China Telecom’s Inner Mongolia data centre, spanning 10.5 million square feet. For comparison, that is roughly the size of 182 American football fields. Among colocation providers, Equinix holds the most global capacity by active IT load, according to ABI Research.

Six major operators, one clear pattern: the market splits between colocation landlords (Equinix, Digital Realty) and cloud hyperscalers (AWS, Azure, Google Cloud). NTT bridges both categories. The implication: for a smaller operator like Propagate Networks, the choice between colocation and cloud shapes everything from capex to latency strategy.

What is the biggest issue with data centers?

Environmental impact tops the list. Data centres consume roughly 1% of global electricity, according to the International Energy Agency, and a single hyperscale facility can draw as much power as a medium-sized town. Water use for cooling adds another layer of tension, especially in drought-prone regions.

Environmental impact of data centers

  • Electricity consumption: ~1% of worldwide use, projected to grow as AI workloads multiply
  • Water usage: traditional cooling towers can consume millions of gallons per year per facility
  • Carbon emissions: while many operators buy renewable credits, actual grid dependency remains high

Energy and water consumption

A typical data centre operates at an average Power Usage Effectiveness (PUE) of 1.3 — meaning 30% more energy is consumed than what the IT equipment uses directly. The rest powers cooling, lighting, and security. Fortune Business Insights projects the global market to reach USD 699.13 billion by 2034, which means more facilities — and more strain on local resources.

The catch

Energy efficiency improvements (better UPS systems, liquid cooling) are cutting PUE, but total power consumption rises because the number of facilities grows faster than efficiency gains. Communities see the strain on their grid but not the offsetting benefits.

The pattern: the industry’s growth solves one problem (data demand) but creates another (local resource competition). For residential neighbours, that competition feels immediate and personal.

Why are people saying no to data centers?

Community opposition has become a major headwind for data centre development. A Gallup poll found that 56% of Americans oppose AI data centres being built near their homes. That is not a fringe sentiment — it is a clear majority.

Americans oppose AI data centers in their area

  • 56% oppose, only 24% support (Gallup)
  • Top reasons: noise from backup generators and cooling fans, property value concerns, and health worries
  • Organised community groups have delayed projects in Virginia, Arizona, and Oregon

The opposition is not ideological. It is practical: residents worry about 24/7 industrial noise, electromagnetic fields (EMFs), and changes to the character of their neighbourhood. Representatives from the Environmental Health Project have raised questions about long-term health risks, though peer-reviewed studies remain inconclusive.

Bottom line: For local governments, the data centre approval process demands transparent impact assessments before permits are issued. For developers, investing in soundproofing, landscaping, and community benefit agreements upfront can prevent years of delays from organised opposition.

Is it safe to live next to a data center?

Most health studies find no serious risks from living near a data centre, but the evidence is not complete. Noise and electromagnetic fields are the two main concerns cited by opponents.

How to protect your home from data center impacts

  • Soundproofing: double-glazed windows and solid-core doors reduce generator and HVAC noise by 20-30 dB
  • Landscaping: earthen berms and dense evergreen plantings buffer sound
  • Monitoring: independent noise meters and EMF readers can provide data for community discussions
  • Setback requirements: many local governments now require 200-500 feet between data centres and homes

A well-designed data centre with modern cooling and noise mitigation is unlikely to cause measurable health harm. But poorly designed facilities — especially those with outdoor diesel generators — can create genuine quality-of-life issues.

Who actually pays for data centers?

Data centres are expensive to build and operate. A single hyperscale facility can cost $500 million to $1 billion. The money comes from a mix of sources.

Who pays to power a data center?

  • Tech companies foot the capital costs for cloud and colocation facilities
  • Private equity funds a growing share of speculative builds
  • Public subsidies include tax abatements, utility rate discounts, and infrastructure grants — often shifting some cost to local governments and ratepayers
  • Power costs are ultimately passed to customers through rack space fees or cloud service pricing

Researchers at Warrington College of Business note that the exact breakdown varies by region. In some US states, data centres receive 10-20 year property tax exemptions, meaning schools and municipal services may see no direct revenue for the first decade of operation.

The consequence: local residents bear noise and grid strain, while the tax benefits flow to corporations. For smaller network operators like Propagate Networks, the buildout of nearby data centres lowers peering costs — but only if the community actually approves the project.

What to watch

The subsidy game is shifting. Some US states are tightening data centre tax breaks after public backlash. If subsidies shrink, buildout slows — and network operators lose projected connectivity gains.

Frequently asked questions

What are the different types of data centers?

Enterprise data centres, colocation centres, hyperscale cloud data centres, edge data centres, and modular data centres. Each serves a different scale and purpose.

How big are data centers typically?

Enterprise data centres range from 1,000 to 10,000 square feet. Hyperscale facilities exceed 100,000 square feet; the largest, China Telecom’s Inner Mongolia site, spans 10.5 million square feet.

What is a hyperscale data center?

A facility designed to support massive cloud and AI workloads, typically owned by AWS, Microsoft, or Google, with 100,000+ servers and custom networking.

Do data centers create local jobs?

Construction jobs are temporary (12-24 months). Permanent operations staff are small — often 20-50 people per facility — because data centres are highly automated.

How are data centers cooled?

Methods include air cooling, liquid cooling, immersion cooling, and free air cooling. Liquid cooling is becoming standard for high-density AI racks.

What is the difference between a data center and cloud computing?

A data centre is the physical building with servers and networking. Cloud computing is the service layer that runs on top of those data centres, abstracting hardware from users.

Are there benefits to having a data center nearby?

Lower latency for local businesses, potential tax revenue (though often deferred), and faster internet backbone connectivity for the region.

For Propagate Networks and operators like it, the data centre landscape is a double-edged sword: cheaper interconnection if the facility gets built, but the timeline depends on local politics as much as on engineering. The choice is clear: engage communities early with transparency and concrete mitigation plans, or watch projects get stalled by organised opposition.
