In brief
As the world's internet traffic passes through Northern Virginia, local campaigners like Julie Bolthouse call for immediate reforms to mitigate the environmental impacts caused by the surge in data centres, which are contributing to climate concerns and resource strain.
Julie Bolthouse, a dedicated environmental campaigner, is leading the charge against the rapid proliferation of data centres in Northern Virginia, which currently hosts the largest concentration of such facilities in the world. Known as the "Wall Street of the data centre industry," this area is not a title that Bolthouse takes pride in. As the director of the Piedmont Environmental Council, she highlights the environmental consequences of these expansive warehouses that house countless computers dedicated to processing data for websites, corporations, and government entities.The growth of data centres in Virginia has been catalyzed since the 1990s due to its strategic location close to Washington, D.C., coupled with historically low energy costs and affordable land. The city of Ashburn, approximately 35 miles west of the capital, is now at the epicenter of "Data Centre Alley," hosting over 477 data centres—far surpassing Texas and California, which hold second and third place, respectively, for the most data centres in the U.S.The burgeoning demand for data storage, particularly due to the rise of artificial intelligence (AI) requiring increased computing resources, has spurred an expected doubling of data centre capacity in the coming years, as reported by Moody's. As a result, residents like Ms. Bolthouse are becoming increasingly concerned about the impacts this growth is having on their surroundings, citing the construction of new electricity lines over protected lands, the rising consumption of water, and the pollutants emitted from diesel generators degrading air quality.Furthermore, local households are now faced with the burden of financing the necessary upgrades to electricity infrastructure, necessary to meet the growing demand from these data centres. In response to these challenges, Bolthouse and her fellow activists are taking action: "We’re working directly on the ground, opposing each data centre application, and educating local planning commissions about the pressing issues at hand," she explains.The discontent with data centre expansions is not isolated to Virginia; parallels can be drawn in other countries such as Ireland, where the energy demands of data centres are straining the national grid. Irish environmental groups like Friends of the Irish Environment are vocal about their opposition, advocating for renewable energy use and scrutinizing new data centre developments with an eye towards sustainability.As the industry faces mounting scrutiny, major tech companies are attempting to ease concerns. This summer, Microsoft made commitments through its Data Center Community Pledge, promising to source 100% renewable energy globally by next year and eliminate waste by 2030. Amazon Web Services has similarly pledged to become "water positive" by 2030 while currently using recycled water in numerous facilities.The ongoing opposition tactics are also showing results internationally: in Uruguay, protests led Google to redesign a facility to use air-cooled systems instead of relying on substantial water resources—an essential change considering the country's recent drought conditions.Bolthouse remains hopeful for the future, emphasizing the long-term necessity for data centre firms to prioritize environmental sustainability. She warns, "If we maintain the current trajectory, electricity prices will continue to escalate, affecting the data centre industry itself along with everyone else."
