The Department of Energy is committed to developing alternative fuels and the infrastructure to support their commercialization.  Through the FreedomCAR and Fuel Initiative, DOE works with industry to develop and deploy advanced transportation technologies that reduce the nation's use of imported oil and improve air quality.

The U.S. Department of Energy's Clean Cities Program supports public-private partnerships that deploy alternative fuel vehicles and build supporting alternative fuel infrastructure. The program features information about local coalitions and clean corridors, alternative fuel news and events, fleet success stories, support and funding, tips for starting a coalition in your area, available alternative fuel vehicles, and more.

Additionally, DOE maintains the Alternative Fuels Data Center, a one-stop shop for all your alternative fuel and vehicle information needs. This site has more than 3,000 documents in its database, an interactive fuel station mapping system, listings of available alternative fuel vehicles, and much more.

The EPAct State & Alternative Fuel Provider Program requires certain fleets to acquire alternative fuel vehicles (AFVs). Compliance is required by state government and alternative fuel provider fleets that operate, lease, or control 50 or more light-duty vehicles (LDVs) within the United States. The Office of Hearings and Appeals (OHA) decides appeals from decisions of the Office of Energy Efficiency and Renewable Energy that deny exemptions from, or assess penalties pursuant to, the Alternative Fuel Transportation Program (AFTP).

Further, the Energy Information Administration compiles data about household vehicle use by consumers.
