Electricity generation involves the conversion of primary energy sources into electrical power, commonly achieved at power plants. In the United States, fossil fuels like natural gas, coal, and petroleum dominate the generation mix, although renewable energy sources such as wind, solar, and hydropower have seen significant growth. As of 2022, approximately 24 percent of U.S. electricity came from renewable sources, and about 20% was nuclear generated (US EIA). Advancements in renewable technologies and supportive policies aim to further increase their share, reducing dependency on non-renewable resources and mitigating environmental impacts.
