What Happens When A Data Center Comes To Town?

Data centers have long supported everyday digital services such as mapping, banking, streaming, and data storage, yet recent AI developments are accelerating their construction and scale. Mark Mills, founder of the National Center for Energy Analytics and author of The Cloud Revolution, explains the practical realities of this expansion for communities where new facilities are sited. The discussion separates established patterns from newer pressures while noting where public concerns often outpace current evidence.

Prior Scale and Recent Acceleration

The United States already operated roughly five thousand data centers before the current wave of attention. The first opened in Santa Clara in 1998. These facilities have powered routine online activity for more than two decades. The change now underway stems from AI workloads that require denser clusters of chips and therefore greater electricity per square foot. Construction activity has shifted from adding many smaller buildings to adding hundreds of substantially larger ones. The total new floor space expected in the next few years exceeds the cumulative additions of the preceding twenty years.
