Coal use in the U.S. contributes to air pollution by releasing sulfur dioxide (SO2) and nitrogen oxides (NOx), which are harmful to the environment and human health.

Burning coal for electricity generation in the U.S. produces harmful pollutants like sulfur dioxide (SO2) and nitrogen oxides (NOx). These emissions contribute to air pollution by forming smog and acid rain, which can damage ecosystems, forests, and water bodies. Sulfur dioxide can lead to respiratory issues, while nitrogen oxides are linked to asthma and other respiratory diseases. These pollutants also play a significant role in climate change by contributing to the formation of particulate matter. Despite a shift towards cleaner energy sources, coal remains a major source of these harmful emissions, impacting both public health and the environment.
