It is hereby declared to be the public policy of the state that, in order to safeguard life, health, property, and public welfare of its citizens, the production, sale, and use of motor fuel and the pollution caused by certain components of motor fuel are matters affecting the public interest and that a statewide emphasis on the production and use of motor fuel containing agricultural ethyl alcohol as a substitute for polluting components is necessary for the reduction of pollution and will further serve as an incentive for the agricultural economy in this state. The Legislature further recognizes that a fuel crisis is pending in the nation and that the development of an additional source of fuel will provide an energy and environmental benefit to the citizens of this state and to the future economic growth of Nebraska.
