Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity. Ninety-four nuclear reactors in 29 states generate nearly 20 percent of the nation’s electricity, all without carbon emissions because reactors use uranium, not fossil fuels. These plants are always on: well-operated to avoid interruptions and built to withstand extreme weather, supporting the grid 24/7.
All that power and potential from a tiny atom.
Benefits of Nuclear Energy
Nuclear energy offers many advantages as the emissions-free workhorse of our energy grid. Its unique value cannot be found in any other energy source.
Nuclear protects national security. U.S. leadership in nuclear energy maintains safety and nonproliferation standards globally, supports a resilient electrical grid at home, and fuels a strong navy.
Nuclear fights climate change. Nuclear energy provides large amounts of 24/7 carbon-free electricity now, which is irreplaceable in protecting the environment.
Nuclear ensures U.S. leadership in technology. The United States pioneered nuclear energy for the world and, with continued leadership, can respond to growing clean energy demand worldwide with advanced reactors.
Nuclear produces electricity reliably. Around-the-clock electricity is a must for our nation to prosper in the 21st century. Clean, reliable nuclear energy is a critical part of U.S. infrastructure because it runs nonstop for 18-24 months at a time.
Nuclear generates jobs. Nuclear energy provides more than 100,000 well-paid, long-term jobs and supports local economies with millions of dollars in state and local tax revenues.
Nuclear protects our air. Nitrogen oxide, sulfur dioxide, particulate matter and mercury: all things you don’t want in the air you breathe. Nuclear energy provides power 24/7 without a trace of those pollutants.
Nuclear boosts international development. Nuclear energy helps developing nations meet sustainable development goals.
Nuclear powers electric vehicles. Electrified transportation promises to reduce carbon emissions. When powered by carbon-free nuclear energy, electric vehicles can reach their full potential.
