Explosive Growth of Data:
- New data created, captured, copied, and consumed globally has risen from 1.2 ZB in 2010 to 149 ZB in 2024
- Data is growing at a compound annual growth rate of 20–43% in the U.S. (27% globally), with doubling of data creation occurring every two years within many of the largest organizations
- 100 million+ servers now operate worldwide
- Drivers include cloud adoption, mobile devices, streaming, e‑commerce, and AI
Rapidly Rising Energy Consumption
- Energy consumption by US data centers grew from 60 TWh (2016) to 366 TWh (2025)
- The electrical load is projected to triple again by 2028, reaching 6.7–12% of U.S. electricity consumption
- On a global scale, data centers were estimated to account for about 1.5% of electricity consumption in 2024 and projected to be about 3% in 2030
- Data center impact on national electricity consumption is geographically concentrated — VA, CA, TX, OH, IL, NY
Water Demand & Infrastructure Impacts
- Water is consumed at two points in data center operation: 1) in cooling of data centers and the servers within them 2) in generating the electricity that data centers consume
- Average data center uses 450,000 gallons/day
- Hyperscale centers can use millions of gallons/day
- Data centers primarily draw upon potable water from municipal or regional water utilities which can strain existing infrastructure or require expensive upgrades
AI As A Major New Load Driver
- AI is reported to require more energy than traditional internet uses, tapping potentially hundreds or thousands of servers in far flung locations to generate answers
- AI training clusters can each require 10,000 watts
- AI applications accounted for 10-20% of data center power consumption in 2024 and by 2028, AI may represent over half of data center electricity use
- A Chat GPT query requires 10-12% more energy than a Google search , while the least efficient image generation model consumes over 500 times the power as the most efficient
Cooling Technology Shifts
- While evaporative cooling dominates data center operations, it demands substantial water use and produces contaminated runoff that can exceed standard municipal treatment capabilities.
Direct-to-Chip Liquid Cooling
- Liquid-cooled plates placed directly on processors
- Heat carried away through circulating coolant
- Reduces both energy and water use compared to air cooling
Immersion Cooling
- Servers submerged in non-conductive cooling fluids
- Highest cooling efficiency and lower energy use
- Eliminates need for traditional cooling water
Cost & Infrastructure Tradeoffs
- Liquid cooling systems are significantly more expensive
- Immersion cooling can cost ~50%+ more than direct-tochip systems
- Advanced systems (boiling fluids) increase costs further
Environmental & Safety Risks
- Risk of fluid leaks or spills Some cooling fluids contain hydrocarbon oils or PFAS chemicals
- Requires biocontainment and spill protection systems
- Some fluids are flammable, adding fire safety concerns
Reducing Environmental Impacts of Data Centers
Data Centers are Here to Stay
- Why they matter: Create jobs, economic growth, and tax revenue. Enable cloud services, streaming, global connectivity, and secure data storage.
- The Challenge: Extremely high energy and water use. Can strain local utilities and infrastructure. Contribute to higher electricity costs and water stress.
Who Can Reduce the Impact?
- Businesses & Large organizations, Local governments, individual users
- Reducing data centers requires action at every level
Impact Reducing Strategies
Businesses & Large Organizations:
Choose sustainable data center providers
- Powered by renewable energy
- High energy efficiency (PUE close to 1.0)
- Low water use (lower WUE)
- Uses advanced cooling, energy, and water-saving technology
- Transparent & independently monitored water and power use
Improve data storage practices
- Use tiered data retention
- Delete outdated, duplicate, or unnecessary data
- Move rarely used data to lower‑energy storage (tape or cold storage) Compress files to reduce storage needs
Local Government Units:
Key questions for data center proposals
- What is the scale and purpose (AI? crypto mining?)
- Expected annual energy and water use
- Will renewable energy be used?
- What cooling technology will be employed?
- Water sources, wastewater volume, and discharge plans
- Energy & water efficiency measures
- Commitment to transparent, independent monitoring
- Backup power plans (generators, batteries)
- Spill containment (for liquid cooling)
- Noise mitigation plans
Individuals
Everyday choices matter
- Streaming uses energy beyond your home—turn it off when not in use
- HD streaming = 8× more carbon emissions than standard definition
- Downloading frequently viewed content uses ~75% less energy than re‑streaming
- Open browser tabs continuously consume data and energy
- Cloud storage consumes 24/7 energy and water—more than local storage
Reduce digital waste
- Think before uploading files or sharing with multiple recipients
- Compress files before emailing or storing
- Don’t automatically include entire email threads when replying
Big Picture Takeaway
Smarter data use + better policies + sustainable infrastructure = lower environmental impact
