Rapidly rising gas prices across the country are shining a spotlight on the dire consequences of America’s dependence on oil. Our continued use of oil puts our environment, our health, and our national security at risk, and with prices across the country exceeding $4 per gallon, it is putting an incredible burden on our economy and on American families.

Dirty energy pollutes the air we breathe, threatening our health and our environment. 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.
