Northern Virginia’s Knowledge Middle Alley lives as much as its nickname. Huge, windowless buildings proliferate beside suburban neighborhoods, looming over cul-de-sacs. Dwelling amongst these imposing buildings—warehouses filled with servers, the bodily embodiment of the web world—seems like “residing inside a pc,” says Julie Bolthouse, director of land use on the nonprofit Piedmont Environmental Council.
The realm has been a hub for digital infrastructure for many years, however lately, improvement has exploded. In 2016 Loudoun County hosted 8.8 million sq. toes of data-center flooring house. By 2020 that determine had greater than doubled, and it has since doubled as soon as once more, with yet one more doubling on the horizon.
Synthetic intelligence is one main cause for the growth. The know-how powers all kinds of on-line experiences, from packages that predict your search question to apps that identify birds. However some consultants are particularly involved concerning the newer progress of generative AI. These instruments, which might write emails, conjure images, and compose music based mostly on a person’s immediate, require intense computing energy—and huge portions of electrical energy. Specialists warn that AI’s insatiable urge for food may derail efforts to ditch fossil fuels and confront local weather change. “Decarbonization is in danger,” says College of Chicago laptop scientist Andrew A. Chien. “Progress is in danger.”
“Decarbonization is in danger. Progress is in danger.”
Loudoun County epitomizes these tensions. Energy demand grew within the county by 340 p.c between 2018 and 2023. To feed information facilities, the regional grid operator plans to maintain working coal vegetation in West Virginia and Maryland that had been beforehand scheduled for retirement. Dominion Power is constructing a pure fuel plant 100 miles to the south for a similar objective, regardless of native opposition.
Generative AI requires large power as a result of it churns by means of terribly advanced math. Each line of textual content from a chatbot requires billions of calculations, says Shaolei Ren, affiliate professor {of electrical} and laptop engineering on the College of California, Riverside. Writing a single e-mail with ChatGPT can use as a lot power as driving a two-ton electrical automobile half a mile, Ren says.
“AI is a basically completely different computing paradigm,” Chien says. “It has this type of limitless potential for progress which means it’s a must to pay additional consideration to it.” In 2022 information facilities accounted for about 4.5 p.c of U.S. power demand. By 2030 that determine may attain 17 p.c, due largely to generative AI, per a Bloomberg analysis.
AI supporters say that, with the rise of carbon-free energy sources, the know-how doesn’t must be an environmental drawback. Nevertheless, in america renewable power manufacturing has grown by solely about 1 p.c per 12 months since 2010, notes Chien. To offset worst-case power demand forecasts for information facilities alone, that charge would abruptly must greater than double.
In response, firms are in search of out different sources of carbon-free power. Constellation Power and Microsoft are working to reopen the notorious Three Mile Island nuclear plant, with the help of taxpayer {dollars}, solely to energy information facilities. Google plans to depend on small modular nuclear reactors, which have but to be constructed. In the meantime, Microsoft’s and Google’s embrace of information facilities and AI has prompted each firms’ carbon emissions to spike, in response to their 2024 sustainability stories.

To place AI on a extra accountable trajectory, regulators ought to require transparency and company accountability, says Priya Donti, an MIT laptop scientist and cofounder of the nonprofit Local weather Change AI. Loudoun County has moved in that course, giving the county board extra discretion over mission approval. Congressional Democrats launched laws in 2024 to guage AI’s environmental affect, which additionally consists of important water consumption to maintain servers from overheating. Working 10 ChatGPT queries requires as much as 2 liters of water, Ren estimates.
Some confirmed options may additionally assist, akin to constructing information facilities in locations with loads of water and carbon-free power. Including power storage eases pressure on the electrical grid when the solar isn’t out and the wind isn’t blowing, and firms can go additional by shifting their most energy-intensive duties to instances when there’s surplus.
But for companies to undertake sustainability measures, they’ll want exterior prodding: tax breaks for reducing emissions, extra oversight on new improvement, or outright restrictions on when, the place, and the way information facilities may be constructed. At this stage, all choices must be on the desk, Ren says. In any other case, “I’m not hopeful that the tech trade will have the ability to resolve this drawback by itself.”
