The BBC recently published an article discussing data centers — specifically, how Northern Virginia is leading the charge. What does this mean for you? Let’s find out.

What are data centers?

Let’s begin with the basics. According to Amazon Web Services, “a data center is a physical location that stores computing machines and their related hardware equipment.” These centers first cropped up in the 1940s, when early computers required larger components.

Now, tech companies are using these data centers for a variety of computing needs, including training and operating artificial intelligence. Watch this video for a brief explanation.

Data centers in Northern Virginia

Nicknamed “Data Center Alley,” Loudoun County — particularly Ashburn — has become a global leader in data center development. Currently, there are 199 operating data centers in Loudoun County, operating on approximately 49 million sqft of land. According to a graph from Synergy Research Group, Northern Virginia accounts for 14% of the world’s operational data center capacity, while Beijing, China, and the state of Oregon follow, each representing 6%.

Why is this? Shane Greenstein, a Harvard professor who writes about the economic geography of data centers, states that the reason for so many being here can be attributed to how cheap the land was, specifically outside of the Dulles Airport.

Fairfax County is home to 20 data centers according to a report from December 2024, and Prince William County is home to 44 data centers with 15 more on the way.

Benefits of data centers

According to the Northern Virginia Technology Council, there are four main benefits for implementing data centers in your area: economic growth, jobs + skills, cross-sectoral growth, and innovation.

Loudoun County officials explain that these data centers contribute to $1 billion in annual tax revenue, which is one-third of the budget. Officials have lowered the residential tax rate — see how much this is saving Loudoun residents.

Concerns regarding data centers

At the same time, these data centers have brought a continuous humming sound to Loudoun County and led and to rising electricity bills for residential customers.

Additionally, data centers come with an environmental impact, including water consumption. According to the Environmental and Energy Study Institute, “a medium-sized data center can consume up to roughly 110 million gallons of water per year for cooling purposes.”
