Unlike many other electricity sources, nuclear power produces no air emissions during daily operations.

Since 1990, the net megawatt hours produced by FirstEnergy Nuclear Operating Company plants – the Perry Plant in Perry, Ohio, Davis-Besse Nuclear Power Station in Oak Harbor, Ohio and Beaver Valley Power Station in Shippingport, Pennsylvania – have resulted in more than 720 million tons of avoided carbon dioxide emissions.  (See chart below)

According to the Nuclear Energy Institute (NEI), nuclear generated electricity avoided almost 595 million metric tons of carbon dioxide in the U.S. in 2014. Without nuclear plants, all of the nation’s 135 million passenger cars would have to be eliminated to keep U.S. carbon dioxide emissions from increasing. More than 400 nuclear power plants worldwide produce nearly 11 percent of the world’s electricity, while reducing carbon dioxide emissions by more than 2.5 billion metric tons per year.

In addition, nuclear power plants require less land area than all other energy sources – which aids conservation and wildlife efforts across the U.S.  Many nuclear plants actually have wildlife sanctuaries on site, because of the negligible impact on the surrounding area.

Carbon Dioxide Emissions Avoided

  • In 2014, nuclear energy accounted for 62.9 percent of emission-free generation in the United States.

  • Worldwide nuclear energy avoids on average the emissions of about 2.5 billion metric tons of carbon dioxide per year.
