Data Center Concerns

Data centers can create significant environmental and public health risks for nearby communities. Their construction and operation generate constant noise from heavy equipment, generators, and cooling systems, sometimes exceeding levels that disrupt both residents and wildlife. Alongside noise, these facilities often rely on diesel backup generators and large energy systems that contribute to air pollution, raising concerns about respiratory health and long-term exposure for people living close by.

Beyond immediate pollution, data centers place heavy demands on local resources and infrastructure. They require large amounts of electricity and water to operate, which can strain local supplies, increase costs to residents, and impact ecosystems. These burdens are often unevenly distributed, with surrounding communities facing environmental and health impacts while receiving limited economic benefit, raising broader concerns about sustainability and environmental impacts.

New Albany, Ohio Data Center - Before and After
💧 Water Consumption

Concern: Data centers require significant water resources to keep servers cool, creating pressure on local water supplies.

  • A 1 MW data center using traditional evaporative cooling can consume approximately 25.5 million liters (6.7 million gallons) of water per year, or roughly 18,000 gallons per day.

  • A large hyperscale facility operating at 100 MW could require millions of gallons of water annually, depending on cooling design.

  • Research estimates that U.S. data centers could require 697 million to 1.45 billion gallons of additional water capacity per day by 2030 if current water-use patterns continue.

  • More than 60% of a data center’s total water footprint can come indirectly from electricity production, not just onsite cooling.

  • Water demand can be especially concerning in drought-prone regions where communities already face water restrictions.

⚡ Electricity Consumption

Concern: Data centers are among the fastest-growing sources of electricity demand due to cloud computing and AI.

  • Data centers consumed approximately 415 terawatt-hours (TWh) of electricity globally in 2024, about 1.5% of worldwide electricity consumption.

  • Global data center electricity use is projected to reach approximately 945 TWh by 2030, comparable to the current electricity consumption of Japan.

  • AI-focused servers are significantly increasing energy demand because they require far more computing power than traditional workloads.

  • A single large data center campus can require 100+ megawatts of continuous power, equivalent to the electricity demand of tens of thousands of homes.

🔌 Strain on Local Power Grids

Concern: Large data centers can create sudden increases in local electricity demand and require major infrastructure upgrades.

  • Some regions are experiencing grid constraints because data center demand is growing faster than new generation and transmission capacity can be built.

  • AI data centers are increasingly seeking dedicated power sources because grid availability has become a limiting factor for expansion.

  • New facilities may require:

    • New electrical substations

    • Transmission upgrades

    • Expanded natural gas or renewable generation capacity

    • Long-term utility commitments

🏗️ Real Estate and Land Use Impacts

Concern: Data centers consume large amounts of land while creating relatively few permanent jobs.

  • Hyperscale data centers often require hundreds of acres for buildings, substations, backup generators, and security infrastructure.

  • Large campuses can replace agricultural land, forests, or undeveloped areas with industrial-scale facilities.

  • Industrial zoning changes may permanently alter rural or suburban landscapes.

  • Large facilities can increase demand for industrial land, potentially raising property values and changing local development patterns.

🔊 Noise Pollution

Concern: Cooling equipment and backup systems can create continuous industrial noise.

  • Sources include:

    • Cooling fans

    • HVAC equipment

    • Chillers

    • Mechanical systems

    • Diesel generator testing

  • Unlike traditional factories, data centers operate 24/7, meaning noise can be continuous.

  • Nearby residents may experience:

    • Sleep disruption

    • Reduced quality of life

    • Loss of rural or residential character

🌫️ Air Pollution

Concern: Backup power systems and electricity generation can contribute to air emissions.

  • Large data centers often maintain dozens of diesel generators for emergency backup power.

  • Generator testing can release:

    • Nitrogen oxides (NOx)

    • Particulate matter

    • Carbon monoxide

    • Greenhouse gases

  • A facility relying heavily on fossil fuel-generated electricity can have a larger carbon footprint than one powered by renewable energy.

🌊 Water Pollution and Ecosystem Impacts

Concern: Cooling systems and infrastructure can affect surrounding water systems.

Potential risks include:

  • Heated water discharge affecting aquatic ecosystems

  • Chemical additives used in cooling systems entering wastewater streams

  • Stormwater runoff from large paved sites carrying pollutants

  • Increased demand on municipal water treatment infrastructure

🏘️ Local Community Impacts

Concern: Communities hosting data centers may experience infrastructure and quality-of-life changes.

Potential impacts include:

  • Increased construction traffic and heavy equipment

  • Road wear and infrastructure costs

  • Visual impact from large industrial buildings

  • Reduced availability of agricultural or open land

  • Community debates over tax incentives and economic benefits

💼 Economic Benefit vs. Community Cost

Concern: Data centers can provide investment but often create fewer long-term jobs than their size suggests.

  • Construction may create hundreds or thousands of temporary jobs.

  • Permanent staffing is typically much smaller because facilities are highly automated.

  • Communities must weigh:

    • Tax revenue

    • Infrastructure costs

    • Resource consumption

    • Environmental impacts

🫁 Potential Health Risks

Concern: Nearby residents may face increased exposure to environmental stressors.

Potential concerns include:

  • Long-term exposure to diesel emissions

  • Increased particulate matter exposure

  • Chronic industrial noise exposure

  • Stress and sleep disruption from persistent noise

  • Air quality concerns for vulnerable populations
