As of recent data, nuclear power accounts for about 20% of the total electricity generated in the United States. There are approximately 93 commercial nuclear reactors operating across the country, contributing around 800 billion kilowatt-hours of electricity annually. This makes nuclear energy a significant part of the U.S. energy mix, second only to natural gas and ahead of coal and renewables. If you need the most current statistics, itβs a good idea to check the latest reports from the U.S. Energy Information Administration (EIA).
