The main sources of energy in the U.S. include natural gas, which has become the dominant source due to its abundance and lower emissions compared to coal. Renewable energy sources, such as wind and solar, have been rapidly growing and contribute significantly to the energy mix. Coal usage has declined markedly, while nuclear power remains a stable source of low-carbon energy. Overall, the U.S. energy landscape is increasingly diversifying toward cleaner and more sustainable options.
