As of recent data, nuclear power contributes approximately 20% of the electricity generated in the United States. This figure has been relatively stable over the years, though the exact percentage can vary slightly based on annual changes in energy production and consumption.
Nuclear power plays a significant role in the U.S. energy mix, providing a substantial portion of the country's low-carbon electricity. Despite the overall percentage, the actual share of total electricity generation can fluctuate due to various factors, including changes in other energy sources, regulatory policies, and the performance of existing nuclear plants.
For the most current and specific figures, consulting the U.S. Energy Information Administration (EIA) or similar authoritative sources would provide the latest statistics.
