What percentage of electrical energy generated in the US is approximately produced by nuclear power plants?

Nuclear power plants are a significant source of energy in the United States, contributing approximately 20% of the nation's electrical energy generation. This percentage has remained relatively stable over the years, reflecting the reliance on nuclear energy as a component of the overall energy portfolio. Nuclear power is favored for its ability to produce large amounts of electricity without emitting greenhouse gases during operation, making it a crucial player in discussions about energy sustainability and climate change. Understanding this percentage is essential for environmental health specialists as it relates to energy policies, infrastructural considerations, and the environmental impacts associated with various energy sources in their work.
