Inside America’s Data Centers

America’s data center story reaches back to the 1940s. ENIAC, developed at the University of Pennsylvania during World War II, helped establish the foundation of modern electronic computing. IBM opened its first commercial data center in 1960. What began with room sized machines has become a national infrastructure hidden behind ordinary screens.

A data center is not simply a warehouse filled with computers. The industry standard, ANSI/TIA 942, defines requirements covering the facility’s site, architecture, electrical systems, cooling, telecommunications, fire protection, security and monitoring. The standard applies to everything from start-up facilities to massive hyperscale campuses and small facilities.

The U.S. now leads the world by an enormous margin. Stanford’s 2026 AI Index, using Cloudscene data, counted 5,427 U.S. data centers in 2025. Germany had 529, the United Kingdom 523 and China 449. The exact number varies because there is no single federal registry and databases use different definitions, but America’s lead is indisputable.

And the number is rising.

The Department of Energy estimates U.S. data centers consumed 176 terawatt hours of electricity in 2023, approximately 4.4% of national electricity use. Its 2024 report projected consumption could reach 325 to 580 TWh by 2028, representing 6.7% to 12% of U.S. electricity. Berkeley Lab’s later analysis projects data centers could account for 11.8% of U.S. electricity consumption by 2030, with a possible range of 9.5% to 15.3%.

Those numbers deserve scrutiny, but so do the assumptions behind them. Texas recently confronted more than 474 gigawatts of data center power requests, while proposed demand elsewhere reached another 270 GW. Much of that is speculative “ghost demand,” not electricity that confirmed facilities will necessarily consume. Texas, Pennsylvania and other states are tightening requirements because exaggerated projections can distort grid planning and potentially shift costs onto consumers.

Environmental imacts are another concern. Data centers consume electricity and some consume substantial quantities of water. Cooling systems vary. Newer closed loop systems can repeatedly circulate water, while evaporative systems consume more. Electricity sources also matter. In 2024, U.S. data centers were powered by roughly 40% natural gas, 24% renewables, 20% nuclear and 15% coal. The mix is changing, with renewables expanding and coal declining, while natural gas remains the largest source of new power for data center growth. 

The contradiction is everywhere. We may oppose a massive facility near our homes while carrying a miniature gateway to thousands of them in our pockets. Every search, streamed movie, cloud photograph, online purchase, social media post, video call and AI prompt creates computing demand. We are not merely watching the data center revolution. We are financing its growth with our daily habits.

Then comes AI.

Pew found in 2026 that 52% of Americans were more concerned than excited about increasing AI use. Workers have another reason to worry. In Pew’s 2025 research, 32% said AI could eventually mean fewer opportunities for them, compared with only 6% who expected more opportunities. Fear of a technology that can alter careers, wages and entire industries is not irrational. It is a recurring response to technological upheaval.

America has faced that fear before.

The Manhattan Project was authorized by President Franklin Roosevelt on January 19, 1942. Scientists achieved the first controlled nuclear chain reaction on December 2, 1942. Trinity produced the first nuclear explosion on July 16, 1945. In less than 4 years, an experimental scientific effort became a weapon that changed world history.

The comparison has limits, but the strategic lesson remains. Computing capacity, electricity, advanced chips, engineers and infrastructure are now national assets. China understands this. So does America.

That is why information warfare is escalating. Foreign actors can exploit genuine public concerns about electricity, water, jobs and AI, then amplify them online. The danger is not that every criticism is foreign propaganda. The danger is that legitimate concerns can be manipulated by people who want Americans fighting each other instead of competing with them.

America needs more computing infrastructure if it intends to remain competitive, but communities deserve transparent power contracts, credible construction plans, responsible water management and protection against speculative projects and hidden costs. The industry needs scrutiny without hysteria and expansion without deception. 

We may not want data centers in our backyards. But every day, we help create the demand for them through the devices we conveniently hold in our hands. The question is not whether we need this infrastructure. It is whether we are willing to be honest about what it takes to power the convenience we have come to expect.
