Sustainable transportation refers to energy-efficient, affordable modes of transport, including electric and alternative-fuel vehicles, as well as domestic fuels.
The benefits of sustainable transportation in the United States include:
- Cost savings on fuel and vehicles
- Reduced air pollution
- Job creation through increased vehicle and battery manufacturing and fuel production
- Improved accessibility to reliable, affordable transportation options for all Americans
- Enhanced energy security and independence with less reliance on foreign sources of materials and fuels
- Lower net carbon emissions.
Advancing Transportation Innovation in the United States
The transportation sector is critical to the American economy. The Office of Energy Efficiency and Renewable Energy (EERE) offers funding for research and development (R&D) to advance technologies that improve the sustainability, affordability, and efficiency of all modes of transport, including aviation, maritime, rail, and road vehicles. EERE also invests in R&D to advance the use of renewable fuels and feedstocks, such as hydrogen and sustainably sourced biomass, that will position the United States as a global leader in new technologies and sectors. Find open funding opportunities and learn how to apply for funding.
Three EERE offices support R&D to expand access to alternative transportation fuels and improve the energy efficiency, convenience, and affordability of transporting people and goods:
EERE also partners with other agencies to advance sustainable transportation. For example, the U.S. National Blueprint for Energy and Emissions Innovation in Transportation is a landmark strategy for modernizing the transportation sector, developed in partnership with the departments of Transportation and Housing and Urban Development, and the Environmental Protection Agency.
Alternative Fuels and Advanced Batteries
Sustainable transportation options run on alternative fuels, batteries, or both. Alternative fuels can be used in flexible-fuel and dual-fuel vehicles, as well as vehicles with advanced technology, such as hybrid power systems and fuel cells. Alternative fuels help conserve fuel and reduce emissions. They include:
Advanced vehicle battery technologies have a longer driving range and a reduced charging time. Their costs are declining with ongoing R&D. Learn about EERE's work to improve batteries for electric vehicles and support the domestic battery supply chain.
Fuel-Efficient Driving and Vehicles
Fuel-efficient vehicles require less fuel to operate compared with older vehicles. They save fuel costs and emit fewer pollutants. Consumers can save money on gas with Energy Saver tips to improve gas mileage and reduce fuel use. Comparison tools are available on FuelEconomy.gov to find a fuel-efficient vehicle.
Hybrid electric vehicles, plug-in hybrid electric vehicles, and all-electric vehicles use electricity to improve vehicle efficiency. Visit the Alternative Fuels Data Center and FuelEconomy.gov for information on efficient and alternative-fuel vehicles, as well as strategies to save money and fuel, locations of alternative fueling stations, and laws and incentives for alternative fuels and vehicles.
The Joint Office of Energy and Transportation was created through the Bipartisan Infrastructure Law to facilitate collaboration between the U.S. Department of Energy and the U.S. Department of Transportation.
