As artificial intelligence expands, the demand for larger and more powerful data centers continues growing rapidly. Supporters often point to economic growth, investment, and job creation. However, residents across America are increasingly asking difficult questions about electricity demand, water usage, infrastructure, noise, environmental impacts, and long-term community effects.
The following sections explain, in plain language, how large-scale data center development could potentially affect residents across Southwestern Pennsylvania.

Modern AI data centers consume extraordinary amounts of electricity because servers, cooling systems, networking equipment, security infrastructure, and backup systems operate continuously.
Unlike factories or businesses that reduce operations overnight, data centers generally run 24 hours per day, 365 days per year.
Some modern AI facilities may consume electricity comparable to tens of thousands or even hundreds of thousands of homes depending on scale. Researchers increasingly warn that rapid AI expansion is creating new challenges for power generation and grid planning.
Supporting large facilities may require:
• New substations
• Transmission line expansion
• Additional power generation
• Utility infrastructure upgrades
While utilities increasingly explore mechanisms to charge large industrial users for expansion costs, many experts worry residents could still experience higher rates if costs are not properly allocated. Recent analyses suggest electricity demand growth is already contributing to higher utility costs nationally.
Greater demand can create:
• More infrastructure projects near communities
• Increased dependence on additional power generation
• Greater competition for available electricity resources
• Larger transmission corridors and substations
Communities may eventually see more industrial utility infrastructure built closer to homes and neighborhoods.
Servers generate substantial heat.
That heat must be removed continuously.
Many facilities use water-intensive cooling systems to keep equipment operating safely.
Large facilities may consume millions of gallons per day depending on cooling design and facility size. Researchers estimate future AI-related water demand could increase dramatically over the next decade.
Water used by industrial facilities may compete with:
• Homes
• Farms
• Businesses
• Municipal systems
• Streams and ecosystems
Communities experiencing:
• Dry periods
• Aging infrastructure
• Limited supply capacity
may experience additional challenges during high-demand periods.
Large industrial users may require:
• Larger water lines
• Additional treatment capacity
• Sewer upgrades
• Storage expansion
These upgrades may create additional public costs.
Data centers are not silent buildings.
Major noise sources may include:
• Cooling fans
• HVAC equipment
• Transformers
• Backup generators
• Mechanical equipment
• Construction activity
Because facilities operate continuously, noise can also be continuous.
Residents living near existing facilities have reported:
• Persistent humming sounds
• Sleep disruption
• Increased stress
• Reduced quality of life
Some generator systems and industrial equipment may exceed noise levels associated with hearing concerns when measured close to equipment. Researchers increasingly recognize industrial noise as an important quality-of-life concern.
Large campuses may require years of:
• Earthmoving
• Heavy equipment operation
• Truck traffic
• Utility construction
Construction impacts may last significantly longer than many residents expect.
Large data centers frequently maintain extensive backup power systems.
Many facilities rely upon:
• Diesel generators
• Fuel storage systems
• Expanded utility infrastructure
• Additional power generation capacity
Backup systems may produce:
• Nitrogen oxides
• Fine particulate matter
• Carbon emissions
• Volatile organic compounds
Some studies suggest diesel backup systems may create significant localized emissions despite operating intermittently. Researchers increasingly study potential public health impacts associated with large-scale AI infrastructure growth.
Communities may also experience:
• More truck traffic
• Construction emissions
• Utility infrastructure expansion
• Greater industrialization
Job creation is frequently the primary argument used to support data center development.
However, construction jobs and permanent jobs are often very different.
Projects may create:
• Construction jobs
• Trade work
• Engineering opportunities
• Temporary economic activity
Many large facilities employ relatively small permanent workforces compared to their physical size.
Research reviewing more than one thousand facilities found many large facilities employ fewer than 150 permanent workers and sometimes far fewer.
Residents should ask:
• How many permanent jobs exist?
• Are positions local?
• What skills are required?
• Are incentives justified by employment numbers?
Large projects frequently require:
• Tax incentives
• Infrastructure improvements
• Utility expansion
• Public investment
Communities may require:
• Road upgrades
• Utility improvements
• Water expansion
• Emergency service expansion
Infrastructure often remains decades after construction.
If facilities shrink, automate further, or relocate, communities may remain responsible for maintaining infrastructure originally sized for industrial demand. Researchers increasingly warn communities to examine long-term cost recovery carefully.
Modern hyperscale campuses require substantial land.
Some projects exceed hundreds or thousands of acres.
Communities may experience:
• Loss of farmland
• Industrial expansion
• Increased traffic
• More utility corridors
• Visual impacts
Large projects frequently require:
• Substations
• Transmission corridors
• Water infrastructure
• Supporting roads
Communities increasingly question whether industrial-scale infrastructure aligns with long-term planning goals.
Property value impacts remain debated.
However, nearby residents frequently express concerns regarding:
• Industrial appearance
• Noise
• Traffic
• Future expansion
Potential concerns include:
• Reduced buyer interest
• Uncertainty regarding future growth
• Visual impacts from industrial infrastructure
• Increased proximity to utility equipment
Property effects often depend heavily on location and distance from facilities.
Large data centers contain:
• High-voltage equipment
• Backup generators
• Fuel storage
• Battery systems
• Complex electrical infrastructure
Communities may require:
• Additional training
• New equipment
• More emergency planning
• Greater coordination between agencies
Volunteer departments may experience additional burdens responding to specialized infrastructure incidents.
Environmental impacts extend beyond the physical building.
Supporting infrastructure also creates demand.
Communities may experience:
• Higher electricity demand
• More water consumption
• Greater land development
• Larger infrastructure footprints
Growth may require:
• More substations
• More transmission lines
• Additional generation capacity
• Expanded industrial development
Researchers increasingly warn that community impacts extend beyond the building itself and include the entire supporting infrastructure network.
Communities should not simply ask:
“Will this create jobs?”
Communities should also ask:
“What are the long-term costs, benefits, and tradeoffs for residents?”
Transparency, public input, and independent analysis become increasingly important when projects may shape communities for decades.
These concerns do not automatically occur with every project. However, residents deserve transparency, independent analysis, and meaningful public input before developments with impacts of this scale are approved.
Supporters argue data centers:
✓ Create construction jobs
✓ Generate tax revenue
✓ Increase local investment
✓ Support supporting industries such as construction, steel, natural gas, utilities, and trades
✓ Bring economic activity into communities
Large-scale investment can absolutely generate economic activity and new tax revenue in some communities. Some states point to billions in investment and thousands of jobs tied to data center growth.
Many states use incentives to attract data centers.
Examples can include:
• Sales tax exemptions
• Property tax incentives
• Equipment tax exemptions
• Infrastructure incentives
• Utility agreements
At least 36 states have adopted special incentives aimed at attracting data centers. These incentives can significantly reduce tax revenue depending on project structure.
Even if companies pay for buildings themselves, large projects may still create demand for:
• Grid expansion
• Transmission lines
• Substations
• Road improvements
• Water infrastructure
• Emergency service expansion
Researchers increasingly warn that infrastructure expansion may become one of the largest public policy questions surrounding AI growth. Some experts warn costs may eventually be shifted into utility systems or rate structures.
Recent examples show communities are increasingly questioning whether incentives provide sufficient return.
Ohio recently paused new tax exemptions after projected losses increased dramatically from roughly $136 million to nearly $1.6 billion. Policymakers cited the need to evaluate overall costs and impacts before approving additional incentives.
Investigations into some projects found incentives reaching extremely large levels relative to permanent job creation. One investigation found some projects effectively received tax savings approaching millions of dollars per permanent job depending on the project structure.
Economic benefits may include:
✓ Temporary construction employment
✓ Trade work
✓ Supply chain demand
✓ Permanent operational jobs
Residents should ask:
• How many permanent jobs remain after construction?
• How many jobs are local?
• What are the wages?
• How long do benefits last?
Critics increasingly argue permanent employment numbers may be much smaller than construction numbers presented during project announcements.
The question is not:
“Do data centers create money?”
The better question is:
“After incentives, infrastructure costs, utility expansion, and public investment, what is the long-term net benefit for residents?”
Communities deserve numbers, transparency, and clear answers before major infrastructure decisions are made.
