How do increased coal emissions in Iowa affect the American Lung Association?
Increased coal emissions in Iowa may worsen lung health risks for the American Lung Association. The increased reliance on coal power by Iowa utilities, such as Alliant Energy's subsidiary Interstate Power and Light, has led to a significant rise in air pollutants. From 2024 to 2025, emissions of sulfur dioxide and nitrogen oxide increased by over 50% from these utilities. These pollutants, along with fine particulate matter, exacerbate asthma and underlying lung and heart disease, posing a direct threat to the health concerns monitored by the American Lung Association.

-
Iowa utilities reported generation and emissions data to the Federal Energy Regulatory Commission and the Environmental Protection Agency on September 20, 2026. This reporting confirms that coal power generation has been increasing in the state, despite previous shifts toward wind power.
The full event1independent outlet -
From 2024 to 2025, Iowa's two largest electric utilities, MidAmerican Energy and Interstate Power and Light (a subsidiary of Alliant Energy), increased their coal power generation. MidAmerican increased its coal mix from 21% in 2024 to 27% in 2025, while IPL jumped from 12% to 20% in the same period.

Everything about Alliant Energy -
The aging coal fleet in Iowa emits significant amounts of nitrogen and sulfur oxide gases, toxic heavy metals, and fine particulate matter. The increase in coal combustion from 2024 to 2025 resulted in a more than 50% increase in sulfur dioxide and nitrogen oxide emissions from Alliant and MidAmerican, leading to corresponding increases in particulate matter concentrations in air quality monitoring locations.

Everything about Iowa -
These pollutants are known to exacerbate asthma and underlying lung and heart disease, and air pollution is recognized as a significant contributor to cancer risk. The American Lung Association monitors these specific health threats in the state, which already has the second-highest rate of new cancer cases.

Why it matters
The American Lung Association is concerned with the severe public health consequences of air pollution, particularly the exacerbation of asthma and lung disease. The increase in coal generation in Iowa, driven by rising electricity demand from data centers and manufacturing, directly correlates with higher levels of toxic pollutants like sulfur dioxide and particulate matter.
This trend is occurring despite the state's history as a wind-powered leader and the utilities' stated net-zero goals. The reliance on older, less efficient coal technology to meet growing demand highlights the challenges of integrating large-scale renewables, as cleaner alternatives are not being built out quickly enough.
What we don't know yet
- Will the utility-scale wind and solar development slow down further due to rising materials costs and opposition?
- Can advanced energy-storage infrastructure effectively meet demand without requiring a return to coal?
