Data centers power everyday life, and their energy use is rising fast. Trane Technologies' Scott Smith explains what drives data center energy consumption, why cooling matters and how smarter systems cut costs and risk.
NORTHAMPTON, MA / ACCESS Newswire / December 9, 2025 / This article is authored by Scott Smith, Director of Mission Critical Offerings, Trane Technologies.
When people ask what I do as the director of Mission Critical Offerings, the conversation often turns to data centers. Most know these facilities exist somewhere "out there," quietly supporting everything from Spotify playlists to fraud detection in financial systems. Fewer realize how central they've become to daily life - or the scale of the energy and engineering required to keep them running.
Data center energy consumption accounts for over 4% of total U.S. power use, according to the U.S. Department of Energy. That number keeps climbing, and much of the money spent on powering data centers goes to cooling those high-powered computers. Understanding what drives data center energy consumption, and why cooling and reliability matter so much, starts with understanding the very nature of a data center.
What is a data center?
At its heart, a data center is a facility that houses hundreds, thousands or even tens of thousands of servers. Think of them as supercharged computers. These servers are responsible for "computational horsepower" - the ability to process complex transactions, store vast amounts of data, and keep the digital world spinning. When you upload a photo to the cloud, get a recommendation from an AI chatbot, or stream a movie online, your request is being processed somewhere inside a data center.
Before, we used to conduct relatively simple searches and transactions. Now, with the meteoric rise of AI and machine learning, the complexity and demand for computational power have exploded. Much of this new digital intelligence depends on vast "computational horsepower," and that horsepower generates heat.
The growing energy burden of data centers as digital infrastructure
Chips inside server racks can execute billions of calculations per second. This processing also creates heat, and as chip densities and computational needs rise, so does the energy consumed and heat produced. If this heat isn't effectively managed, chips can overheat and shut down, threatening the reliability of digital services for millions of users.
