Key Points

• Nuclear energy plays a vital role in meeting our nation’s electricity needs, protecting the environment and preserving the fuel and technology diversity that is the strength of the U.S. electric supply system. 
• The 104 nuclear power plants in 31 states operate 24/7, producing nearly 20 percent of U.S. electricity while emitting no carbon dioxide, sulfur dioxide or nitrogen oxide (a precursor to ground-level ozone). Nuclear energy produces more electricity than any other source in Connecticut, New Hampshire, New York, New Jersey, South Carolina and Vermont. Nationwide, nuclear plants generated 806 billion kilowatt-hours of electricity in 2008. 
• Only 27 percent of U.S. electricity comes from carbon-free sources, and nuclear power plants generate almost three-fourths of it. 
• The U.S. Department of Energy projects that U.S. electricity demand will rise 21 percent by 2030. Even with conservation and efficiency measures, the U.S. will need hundreds of new power plants from a diverse portfolio of fuel sources to supply electricity for a high standard of living and to promote domestic economic growth. 
• The energy industry is planning to build new, advanced nuclear plants to meet growing electricity demand while enhancing U.S. energy independence and reducing greenhouse gases.
