Since 1993, Clean Cities coalitions have steadily increased their energy use impact each year for a cumulative of more than 7.8 billion gasoline gallon equivalents (GGEs). Clean Cities coalitions have helped to place hundreds of thousands of alternative fuel vehicles on the road and establish the fueling infrastructure to serve this growing market. They have also aided in the elimination of millions of hours of vehicle idling and helped accelerate the entry of new transportation technologies into the marketplace.
Since 1993, the U.S. Department of Energy (DOE) has funded nearly 600 transportation projects nationwide through a competitive application process and has distributed close to $400 million in project awards. These funds have leveraged nearly $800 million in additional matching funds and in-kind contributions from the public and private sectors.
