Clean Air, Healthy Families Reports

When power plants burn coal, oil or gas, they create the ingredients for ground-level ozone pollution, one of the main components of “smog” pollution. Especially on hot summer days, across wide areas of the United States, ozone pollution reaches levels that are unhealthy to breathe, putting our lives at risk. In 2009, U.S. power plants emitted more than 1.9 million tons of ozone-forming nitrogen oxide pollution into the air.
