UNDERSTAND DATA CENTERS
Data Centers Explained in Plain English
Clear, independent information about the infrastructure powering AI, cloud computing, streaming, business, and much of our digital world.
Understand the technology. Understand the numbers. Decide for yourself.
THE BASICS
What Exactly Is a Data Center?
A data center is a specialized facility built to house the computers, networking equipment, storage systems, electrical infrastructure, and cooling equipment that keep digital services running.
Every time you stream a movie, save something to the cloud, make an online purchase, use a search engine, or interact with artificial intelligence, data centers are working somewhere behind the scenes.
UNDERSTANDING THE BIG QUESTIONS
Data Centers Touch More Than Computers
AI
AI & Computing
Understand why artificial intelligence is increasing demand for powerful computing infrastructure.
⚡
Electricity & Power
Explore electrical capacity, energy use, substations, transmission, and the systems that keep facilities operating.
◉
Cooling & Water
See how heat is removed, when water is used, and why cooling approaches vary from one facility to another.
▥
Economics & Jobs
Consider construction spending, tax revenue, employment, infrastructure investment, and incentives.
●●●
Community Impact
Understand questions surrounding land use, utilities, noise, development, infrastructure, and local decision-making.
WHY NOW?
Why Are Data Centers Growing So Quickly?
Cloud computing, streaming, online commerce, digital storage, and connected services have increased demand for data-center capacity for years. Artificial intelligence is accelerating that trend.
Training and operating advanced AI systems can require enormous amounts of computing power. That growth is bringing new questions about electricity, water, infrastructure, jobs, taxes, and community development.
Questions worth asking
- How much electricity could a project require?
- Where will that electricity come from?
- How much water might be used?
- Who pays for new infrastructure?
- What jobs and tax revenue may result?
- How could nearby communities be affected?

INDEPENDENT INFORMATION
Not Pro-Data-Center. Not Anti-Data-Center.
Data centers can create benefits. They can also create legitimate questions and concerns.
The purpose of Understand Data Centers is to explain the technology, resources, economics, potential benefits, potential impacts, and uncertainties as clearly as possible. Where the answer depends on the particular facility, utility system, technology, location, or development agreement, that distinction matters.
The goal is simple: give you enough understandable information to reach your own conclusions.
