The U.S. Department of Energy’s (DOE) Clean Cities program advances the nation’s economic, environmental, and energy security by supporting local actions to deploy alternative and renewable fuels, idle-reduction measures, fuel economy improvements, and new transportation technologies, as they emerge.
Every year, each Clean Cities coalition submits an annual report of its activities and accomplishments for the previous calendar year. Coalition coordinators, who lead the local coalitions, provide information and data via an online database managed by the National Renewable Energy Laboratory (NREL). The data characterize membership, funding, projects, and activities of the coalitions. The coordinators also submit data on the sales of alternative fuels, deployment of alternative fuel vehicles and hybrid electric vehicles, idle-reduction initiatives, fuel economy activities, and programs to reduce vehicle miles traveled. NREL and DOE analyze the data and translate them into petroleum-use and greenhouse gas reduction impacts for individual coalitions and the program as a whole. This report summarizes those impacts for Lone Star Clean Fuels Alliance (Central Texas).
Most of the data shows that there is an decrease in use of alternative fuel vehicles in central Texas. Between 2012 and 2013 as a whole Lone Star Clean Fuels Alliance reported a reduction in usage in alternative fuels, the central texas areas used 407,375 gallons less than the previous year. Although LSCFA reported less alternative fuel use in 2013 most tenured organizations increased consumption of cleaner fuels like CARTS, Ft. Hood, UT Austin, and with the most dramatic increase in use Diesel Green Fuels starting from 1000 GGE’s to over 7,000 gallons of biodiesel! The new stakeholders Clean Fuels USA, R&R Limousine and Tx DOT, have displaced a total of 118,000 gallons of gasoline (GGE’s).
For the most part the reduction of use is attributed mainly from the City of Austin. Only reporting 791,338 gallons of use in 2013, mainly from CNG and LPG heavy-duty trucks and busses. The 2012 report shows an equivalent of 1,111,039 gallons of alternative fuel being used. The decrease of usage could be attributed to the loss of a 3 fleets of light-duty E85 vehicles. In 2012 the city had roughly 2500 alternatively fueled vehicles. In 2013 only 2300 vehicles remained. This accounts to a loss of 319,000 gallons of gasoline being used.
Not all municipalities are behind in clean fuel initiatives. The City of San Marcos in 2012 had used 3305 gallons of gasoline worth of ethanol, but in 2013 implemented light-duty electric vehicles and within each year, each vehicle drove over 1000 miles!
