The EIA notes that different vehicle technologies have different impacts on the energy sector. Fully electric and plug-in hybrid vehicles increase electricity demand because they charge from the grid, while conventional hybrids continue to rely on liquid fuels. Although electric vehicles are gaining market share, they remain a small portion of the overall US vehicle fleet, accounting for only about 2% of registered light-duty vehicles in 2024. The data shows that the transition toward electrified transportation is continuing but has shifted toward hybrids as consumers respond to changing incentives and market conditions.
