# Fuel Economy

The State of California has supported the development of alternative transportation fuels (fuels other than gasoline or diesel) since the creation of the Energy Commission in 1975. Earlier programs included demonstration programs with vehicles using "neat" ethanol and methanol; infrastructure development for methanol/gasoline blends - M85; support for flexible fuel, natural gas and electric vehicles.

Nearly 100 percent of the state's transportation system is fueled currently by fossil fuels. Moving toward a more diversified approach to fuels and supporting the advancement of higher efficiency vehicles is one of the goals of the State's programs.
