Addressing common misconceptions about data centers

The technology world is often filled with myths and misconceptions. This isn’t surprising, given that much of the technology we depend on works behind the scenes. Lately, I’ve heard many discussions about data centers, and it’s clear that some of the ‘facts’ circulating aren’t as accurate as they seem.

Today, I aim to clarify some of these misconceptions, not to spark debates, but to provide accurate information about common myths surrounding technology and AI.

Myth #1: Data centers use excessive water, depleting public resources

Water usage by data centers is a hot topic, yet few understand how these facilities actually utilize water for cooling. While I can’t speak for all data centers, I can share insights from visits to two Meta data centers over recent months.

• Traditional air-cooled compute data center: These centers use water to cool air entering the building, but only for a few months each year.
• AI-optimized closed-loop liquid cooled data center: These facilities use a water-glycol mixture in a closed-loop system, continuously circulating the coolant over server equipment. The system recirculates the same liquid, cooling it down and sending it back around, using minimal water.

The water source for these centers can vary. One site used municipal water while another drew from a permitted on-site well. The well tapped into an aquifer unsuitable for drinking water. In regions with water scarcity, closed-loop systems are standard due to their minimal water use. As observed, these cooling methods mean Meta’s facilities often use less water annually than a typical US golf course.

Myth #2: More data centers lead to higher consumer energy bills

Although data centers consume significant energy, this does not directly increase energy bills for consumers. Meta bears the complete cost of its energy consumption, much like any household. They also fund necessary infrastructure upgrades to support their energy needs. This approach ensures that local communities aren’t burdened with the costs, as Meta collaborates with utility providers long before a data center becomes operational. For instance, in Louisiana, a deal with Entergy ensures Meta covers the costs of new generation and transmission, safeguarding existing customers from additional expenses.

Myth #3: Data centers do not generate employment

It’s crucial to recognize that data centers don’t construct or operate themselves. There are two phases in a data center’s lifecycle that significantly contribute to job creation in local communities:

• Construction: Building a data center involves thousands of skilled tradespeople working on-site, with numerous jobs supported through equipment purchases from various suppliers. These are often multi-year projects that extend with expansions or upgrades.
• Operation: Once operational, data centers require skilled engineers, technicians, IT professionals, and security staff to maintain and manage the facilities.

In many communities, Meta is a leading employer, and their recent launch of America’s Workforce Academy offers free training for careers in skilled trades, guaranteeing employment at a Meta-partner site upon completion.
