Oil, natural gas, and coal provide over 80% of the United State's energy needs, though their share is gradually decreasing.

Oil, natural gas, and coal are the primary sources of energy in the United States, together accounting for over 80% of the nation’s energy consumption. These fossil fuels are crucial for electricity generation, transportation, and industrial production. However, their dominance is slowly declining due to the rise of renewable energy sources like wind, solar, and hydropower. Despite this shift, fossil fuels still play a significant role in the U.S. energy mix. Natural gas, in particular, has gained importance due to its lower carbon emissions compared to coal. The transition to cleaner energy is ongoing but gradual.
