Vehicles

Vehicles, and the fuel it takes to power them, are an essential part of our American infrastructure and economy, moving people and goods across the country. From funding research into technologies that will save Americans money at the pump to increasing the fuel economy of gasoline-powered vehicles to encouraging the development and deployment of electric and alternative fuel vehicles, the Energy Department is committed to providing consumers with a full range of vehicle choices while decreasing our dependence on foreign oil and reducing impacts on the environment.

Vehicles are essential to the movement of people and goods across the United States and play a major role in the nation’s energy use. Cars, trucks, buses, and other transportation systems rely on a range of energy sources to support daily travel, commerce, and economic activity. Understanding how vehicles use energy helps inform decisions about efficiency, technology, and transportation infrastructure.

The Department of Energy supports research, innovation, and programs that advance vehicle technologies, improve fuel economy, and expand transportation options. These efforts help strengthen mobility, support economic growth, and encourage a more efficient and resilient transportation system.

Energy Use in Vehicles

Vehicles use energy in different ways depending on their design, fuel source, and purpose. From gasoline and diesel to electricity and other alternative fuels, transportation technologies continue to evolve to meet changing needs. Improvements in vehicle performance and energy use can help reduce costs, support innovation, and expand options for consumers and industry.
