Clean Cities 2013 Annual Metrics Report

10/20/2014

Each year, the U.S. Department of Energy asks its Clean Cities program coordinators to submit annual reports of their activities and accomplishments for the previous calendar year. Data and information are submitted via an online database that is maintained as part of the Alternative Fuels Data Center (AFDC) at the National Renewable Energy Laboratory (NREL). Coordinators submit a range of data that characterize the membership, funding, projects, and activities of their coalitions. They also submit data about sales of alternative fuels, deployment of alternative fuel vehicles (AFVs) and hybrid electric vehicles (HEVs), idle-reduction (IR) initiatives, fuel economy activities, and programs to reduce vehicle miles traveled (VMT). NREL analyzes the data and translates them into petroleum-use reduction impacts, which are summarized in this 2013 Annual Metrics Report.

National Clean Fleets Partnership

9/16/2014

Clean Cities' National Clean Fleets Partnership establishes strategic alliances with large fleets to help them explore and adopt alternative fuels and fuel economy measures to cut petroleum use. The initiative leverages the strength of nearly 100 Clean Cities coalitions, nearly 18,000 stakeholders, and more than 20 years of experience. It provides fleets with top-level support, technical assistance, robust tools and resources, and public acknowledgement to help meet and celebrate fleets' petroleum-use reductions.

Costs Associated with Compressed Natural Gas Vehicle Fueling Infrastructure

9/9/2014

This document is designed to help fleets understand the cost factors associated with fueling infrastructure for compressed natural gas (CNG) vehicles. It provides estimated cost ranges for various sizes and types of CNG fueling stations and an overview of factors that contribute to the total cost of an installed station. The information presented is based on input from professionals in the natural gas industry who design, sell equipment for, and/or own and operate CNG stations.

Clean Cities Alternative Fuel Price Report, July 2014

7/31/2014

The Clean Cities Alternative Fuel Price Report for July 2014 is a quarterly report on the prices of alternative fuels in the U.S. and their relation to gasoline and diesel prices. This issue describes prices that were gathered from Clean Cities coordinators and stakeholders between July 1, 2014 and July 15, 2014, and then averaged in order to determine regional price trends by fuel and variability in fuel price within regions and among regions. The prices collected for this report represent retail, at-the-pump sales prices for each fuel, including Federal and state motor fuel taxes.

Table 1 reports that the nationwide average price (all amounts are per gallon) for regular gasoline has increased 5 cents from $3.65 to $3.70; diesel decreased 6 cents from $3.97 to $3.91; CNG price increased 2 cents from $2.15 to $2.17; ethanol (E85) decreased 18 cents from $3.41 to $3.23; propane decreased 24 cents from $3.31 to $3.07; and biodiesel (B20) has decreased 3 cents from $4.01 to 3.98.

According to Table 2, CNG is $1.53 less than gasoline on an energy-equivalent basis, while E85 is $0.86 more than gasoline on an energy-equivalent basis.

Clean Cities Alternative Fuel Price Report, April 2014

6/3/2014

The Clean Cities Alternative Fuel Price Report for April 2014 is a quarterly report on the prices of alternative fuels in the U.S. and their relation to gasoline and diesel prices. This issue describes prices that were gathered from Clean Cities coordinators and stakeholders between April 1, 2014 and April 15, 2014, and then averaged in order to determine regional price trends by fuel and variability in fuel price within regions and among regions. The prices collected for this report represent retail, at-the-pump sales prices for each fuel, including Federal and state motor fuel taxes.

Table 1 reports that the nationwide average price (all amounts are per gallon) for regular gasoline has increased 31 cents from $3.34 to $3.65; diesel increased 8 cents from $3.89 to $3.97; CNG price increased 6 cents from $2.09 to $2.15; ethanol (E85) increased 37 cents from $3.04 to $3.41; propane increased 19 cents from $3.12 to $3.31; and biodiesel (B20) has increased 5 cents from $3.97 to $4.01.

According to Table 2, CNG is $1.50 less than gasoline on an energy-equivalent basis, while E85 is $1.17 more than gasoline on an energy-equivalent basis.
