1. NUCLEAR POWER PLANTS PRODUCED 809 BILLION KILOWATT HOURS OF ELECTRICITY IN 2019
The United States is the world’s largest producer of nuclear power. It generated 809 billion kilowatt hours of electricity in 2019—the highest total ever. Commercial nuclear power plants have supplied around 20% of the nation’s electricity each year since 1990.
2. NUCLEAR POWER PROVIDES 55% OF AMERICA’S CLEAN ENERGY
Nuclear energy provided 55% of America’s carbon-free electricity in 2019, making it by far the largest domestic source of clean energy.
Nuclear power plants do not emit greenhouse gases while generating electricity.
They produce power by boiling water to create steam that spins a turbine. The water is heated by a process called fission, which makes heat by splitting apart uranium atoms inside a nuclear reactor core.
3. NUCLEAR ENERGY IS THE MOST RELIABLE ENERGY SOURCE IN AMERICA
Nuclear power plants operated at full capacity more than 93% of the time in 2019—making it the most reliable energy source in America. That’s about 1.5 to 2 times more reliable as natural gas (57%) and coal (48%) plants, and roughly 2.5 to 3.5 times more reliable than wind (35%) and solar (25%) plants.
Nuclear power plants are designed to run 24 hours a day, 7 days a week because they require less maintenance and can operate for longer stretches before refueling (typically every 1.5 or 2 years).
4. NUCLEAR HELPS POWER 29 U.S. STATES
There are currently 96 commercial reactors helping to power homes and businesses in 29 U.S. states. Illinois has 11 reactors—the most of any state—and joins South Carolina and New Hampshire in receiving more than 50% of its power from nuclear.
5. NUCLEAR FUEL IS EXTREMELY DENSE
Because of this, the amount of used nuclear fuel is not as big as you think.
All of the used nuclear fuel produced by the U.S. nuclear energy industry over the last 60 years could fit on a football field at a depth of less than 10 yards.
