Climate Pollution on the Rise: New Power Plants for Data Centers Threaten Pennsylvania’s Environment
A staggering 24 percent increase in greenhouse gas emissions is looming over Pennsylvania, courtesy of at least seven new natural gas-fired power plants designed to supply electricity directly to data centers. This alarming projection, according to a recent report from the Environmental Integrity Project, would place Pennsylvania’s climate pollution on par with adding 14 million cars to the state’s roads every year.
The report, titled “The Power Behind AI,” highlights the urgent need for a reassessment of the data center industry’s reliance on fossil fuels. Data centers, the backbone of the digital revolution, are driving the construction of massive behind-the-meter power plants across the United States. In Pennsylvania, the Marcellus Shale’s vast reserves of natural gas have become a magnet for tech companies seeking to build data centers near an abundant fuel supply. However, this rush towards development has serious consequences for the environment and public health.
The planned power plants in Pennsylvania would generate a combined 14 gigawatts of power, with some of the largest behind-the-meter plants capable of producing over 17.5 million tons of CO2 equivalent annually. The Homer City Generating Station, for instance, would become one of the country’s biggest generators if fully converted to natural gas, emitting over 17.5 million tons of greenhouse gases every year. This is a stark reminder that the data center industry’s insatiable demand for electricity is pushing the world closer to climate disaster.
The national trend is equally alarming, with at least 74 gas-fired power plants planned to fuel the data-center industry, generating a staggering 662 million tons of greenhouse gases annually. This would be equivalent to the annual emissions of Australia or placing 140 million cars and trucks on the road, according to the report. In aggregate, the plants identified by the study would generate three times as much power as California uses.
The report’s lead author, Griffin Bird, cautions that these estimates are likely to understate the problem, as the survey only covered large behind-the-meter plants. Pennsylvania, for instance, has 66 data center projects proposed, approved, or under construction, with some of these projects involving behind-the-meter power plants that were not captured by the survey.
The implications of this trend are far-reaching and devastating. Alex Bomstein, executive director of the Clean Air Council, warns that the proposed Homer City plant would be the largest single pollution source in the state, posing significant risks to public health and the environment. “That’s 250 new toxic intrusions into neighborhoods across Pennsylvania, Ohio, and West Virginia, on and on, for as long as the plant is running,” Bomstein said during a recent press conference.
The data center industry, however, is not oblivious to the concerns surrounding its environmental impact. Aaron Tinjum, vice president of energy at the Data Center Coalition, claims that the industry is making significant investments in clean energy and next-generation technologies. “Data centers accounted for half of the contracted wind and solar capacity in 2024,” Tinjum said, quoting research by S&P Global. While this is a step in the right direction, it is far from enough to mitigate the climate pollution caused by the industry’s reliance on fossil fuels.
As the world grapples with the devastating consequences of climate change, it is imperative that governments and industries take immediate action to reduce greenhouse gas emissions. The planned power plants for data centers in Pennsylvania are a stark reminder that the clock is ticking, and the consequences of inaction will be catastrophic. As the report’s authors so aptly put it, “Investments in artificial intelligence are driving the construction of a huge wave of data centers and dirty gas power plants across the U.S.”
The Human Cost of Climate Pollution
The human cost of climate pollution is impossible to ignore, particularly in communities that bear the brunt of fossil fuel extraction and burning. The risks to public health are well-documented, from respiratory problems to increased cancer rates. The proposed Homer City plant, for instance, would pose significant risks to nearby communities, with the potential for aquifer contamination and increased air pollution.
The economic impact of climate pollution is equally devastating, with the costs of climate-related disasters and health impacts far exceeding the economic benefits of fossil fuel extraction. The report highlights the urgent need for a transition to clean energy sources, not just to mitigate climate pollution but also to ensure a more sustainable and equitable future for all.
The Road Ahead
As the data center industry continues to grow, it is imperative that governments and industries take immediate action to reduce greenhouse gas emissions. This includes investing in clean energy sources, implementing policies to reduce energy consumption, and promoting sustainable practices throughout the supply chain. The proposed power plants for data centers in Pennsylvania are a stark reminder that the clock is ticking, and the consequences of inaction will be catastrophic.
The people of Pennsylvania, Ohio, and West Virginia deserve better than to be saddled with the risks and consequences of fossil fuel extraction and burning. It is time for governments and industries to take responsibility for their actions and work towards a more sustainable future. The road ahead is fraught with challenges, but with collective action and determination, it is possible to create a better future for all.
