Northern Virginia has the largest

collection of data centers in the nation, according to DatacenterHawk and Data Center Frontier, which analyze the industry. Loudoun County officials assert that up to 70 percent of the world’s Internet traffic passes through that county alone. Among the companies storing and distributing data in Northern Virginia are Amazon.com (founder Jeffrey P. Bezos owns The Washington Post), Microsoft, Google, Facebook and Uber. DatacenterHawk and Data Center Frontier attribute the region’s popularity to factors such as proximity to the federal government, high density of fiber, a business-friendly environment, rare natural disasters and low commercial electricity rates. In a report called “Clicking Clean,” however, Greenpeace contends that Dominion Energy, which powers most of the Northern Virginia data centers, relies on “dirty” sources of generation for 99 percent of the electricity it produces. Dominion responds that it produced 73.5 percent of its electricity through “clean-burning, non-coal fuel sources in 2016.” Here is a map of the 59 Northern Virginia data centers that have publicly shared locations, according to the Virginia Economic Development Partnership.
