The rush to power data centers is weakening the Clean Air Act

The Environmental Protection Agency's new guidance on the Clean Air Act has significant implications for the regulation of pollution from power plants, particularly in the context of the rapidly growing data center industry. By taking away a key tool for tracking pollution, the EPA is making it more challenging for communities to hold power plants accountable for their emissions. This development is concerning, given the critical role that the Clean Air Act has played in reducing air pollution from power plants over the years.

The guidance appears to be a response to the increasing demand for electricity to power data centers, which are essentially large warehouses filled with computer servers that store and process data. As data centers proliferate, they are driving a surge in electricity demand, much of which is being met by fossil fuel-fired power plants. The EPA's decision to allow data centers to build their own power plants, rather than requiring them to rely on the grid, could lead to a proliferation of smaller, less-regulated power sources that are more difficult to track and monitor.

What's next to watch is how this guidance plays out in practice and what impact it has on air quality, particularly in communities already burdened by pollution from power plants. Will the EPA's move lead to an increase in emissions of pollutants like particulate matter, sulfur dioxide, and nitrogen oxides? How will state and local regulators respond to the new guidance, and will they find ways to fill the regulatory gaps created by the EPA's action? As the data center industry continues to grow, it's essential to ensure that the need for electricity is met in a way that prioritizes public health and environmental protection.
