Opposition to AI data centers in the United States is no longer linked solely to general concerns about electricity consumption or rising utility bills. In Philadelphia, the new debate intersects with the memory of communities that lived for decades next to heavy industrial facilities, making promises of jobs and economic growth less convincing to residents who associate the former industry with ongoing health and environmental harms.
One focal point of this debate is the Grays Ferry neighborhood in southwest Philadelphia, where activist Shawmar Pitts grew up next to an oil refinery that was the largest on the East Coast of the United States. The refinery closed after an explosion in 2019, but its social and health effects remain present in residents’ accounts. Pitts, as co-director of the organization Philly Thrive, is leading a campaign calling for a temporary pause on the construction of data centers in the city.
No formal proposals to build a data center in Philadelphia have been submitted so far, but city officials have identified two potential sites, one in Northeast Philadelphia and the other in the Grays Ferry neighborhood. The No Data Centers in Philly movement says residents do not want to add another source of noise and pollution to an area that already bears a heavy industrial legacy.
Why does this news matter?
The case of Philadelphia reveals a problem that goes beyond choosing the site of a single facility. The data centers needed by artificial intelligence companies depend on large amounts of electricity and may require backup diesel generators and additional water sources, while companies are seeking sites capable of accommodating rapidly expanding demand.
According to BloombergNEF, by 2035 U.S. data centers may consume more natural gas than Germany and Japan combined, a forecast that is nearly twice a previous estimate issued nine months earlier. The source states that burning one cubic foot of natural gas releases the equivalent of 60 grams of carbon dioxide, and it estimates that additional demand from data centers could lead to an extra one million metric tons of greenhouse gas emissions per day, or about 12% of current U.S. emissions. These figures are attributed to the sources cited in the report and do not mean that every individual data center will produce the same impact.
The backup infrastructure of the centers adds another layer to the debate. Annie Fox, an attorney at the Clean Air Council, said that a typical data center planned in Pennsylvania could contain hundreds of diesel engines, even if their operation is intended for emergencies. According to what she reported, these engines could be used instead of drawing electricity from an overburdened grid during some heat waves, raising questions about how to balance service reliability with air quality.
What is changing in practice?
Some officials are moving toward temporarily freezing projects rather than approving them quickly. New York Governor Kathy Hochul signed an executive order temporarily preventing the state from approving permits for large projects, saying that data centers should be built in places where they are genuinely wanted. Temporary pauses have also been approved in Denver, Indianapolis, Asheville, Charlotte, and Reno, with the aim of giving authorities time to gather information about the effects of these facilities.
For local communities, the assessment is not limited to the number of jobs announced. Donna Greenberg, a Philadelphia resident, raised concerns about pollution, water, and electricity, as well as access to information and monitoring. Sonya Sanders, chair of Philly Thrive’s board, rejected promises of jobs and linked her position to the experience of her husband, who died in 2020 of a rare bone cancer, which she believes was contributed to by emissions from the refinery. This belief is a personal account, not medical evidence provided by the source.
certi.news’s reading
The actual change here is not the launch of a new project, but the shift of AI data centers from infrastructure that is distant from the public into a local issue of planning, public health, and energy. Philadelphia shows that acceptance of a project will not be decided by economic promises alone, especially in areas that have borne the costs of previous industries.
Basic questions remain open: How much water and electricity would the proposed facility consume? How many permanent jobs would it provide? And what measures would monitor emissions, noise, and the operation of emergency generators? Moreover, according to the article, Philadelphia has no formal construction plan that can yet be evaluated. The current debate is therefore a battle over rules and information preceding the project, not a final judgment on a specific facility.
