Clean Cities Alternative Fuel Price Report, October 2009
10/1/2009
The Clean Cities Alternative Fuel Price Report for October 2009 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 October 16 and October 26, 2009, 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 for regular gasoline has risen 20 cents per gallon from $2.44 per gallon to $2.64 per gallon; CNG has risen 13 cents from $1.73 to $1.86; and ethanol (E85) has risen 14 cents from $2.13 to $2.27 per gallon. CNG is about 78 cents less than gasoline on an energy-equivalent basis, while E85 is about 57 cents more per gallon than gasoline on an energy-equivalent basis.

Advancing New Vehicle Technologies and Fuels
5/1/2009
The Vehicle Technologies Program under the U.S. Department of Energy is actively developing and accelerating the deployment of clean and efficient vehicle technologies, as well as renewable fuels. The Vehicle Technologies program works with industry, universities, and state and local governments to strengthen the economy, create jobs, and reduce the U.S. demand for petroleum.
Impact of Ethanol Use on Food Prices and Greenhouse-Gas Emissions
4/8/2009
The production and use of ethanol in the U.S. have been steadily increasing since 2001, boosted in part by production subsidies. That growth has exerted upward pressure on the price of corn and, ultimately, on the retail price of food, affecting both individual consumers and federal expenditures on nutritional support programs. It has also raised questions about the environmental consequences of replacing gasoline with ethanol. This analysis examines the relationship between increasing production of ethanol and rising prices for food. It estimated how much of the rise in food prices between 4/07 and 4/08 was due to an increase on the production of ethanol and how much that increase in prices might raise federal expenditure on food assistance programs.

Effects of Intermediate Ethanol Blends on Legacy Vehicles and Small Non-Road Engines, Report 1 - Updated
2/1/2009
In summer 2007, the U.S. Department of Energy (DOE) initiated a test program to evaluate the potential impacts of intermediate ethanol blends on legacy vehicles and other engines. The purpose of the test program is to assess the viability of using intermediate blends as a contributor to meeting national goals in the use of renewable fuels. Through a wide range of experimentalactivities, DOE is evaluating the effects of E15 and E20?gasoline blended with 15% and 20% ethanol?on tailpipe and evaporative emissions, catalyst and engine durability, vehicle driveability, engine operability, and vehicle and engine materials.
The purpose of this initial study was to quickly investigate the effects of adding up to 20% ethanol to gasoline on regulated tailpipe emissions for 16 popular late-model vehicles on a drive cycle similar toreal-world driving and 28 small non-road engines (SNREs)? under certification or typical inuse procedures;exhaust and catalyst temperatures of the same vehicles under more severe conditions; temperature of key engine components of the same SNREs under certification or typical in-use conditions; and observable operational issues with either the vehicles or SNREs during the course of testing.

Clean Cities Alternative Fuel Price Report, January 2009
2/1/2009
The Clean Cities Alternative Fuel Price Report for January 2009 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 January 12 and January 30, 2009, and then averaged in order to determine regional price trends by fuel and variability in fuel price within regions and among regions.

Biofuels, Land Use Change, and Greenhouse Gas Emissions: Some Unexplored Variables
1/1/2009
Greenhouse gas release from land use change (the so-called ?carbon debt?) has been identified as a potentially significant contributor to the environmental profile of biofuels. The time required for biofuels to overcome this carbon debt due to land use change and begin providing cumulative greenhouse gas benefits is referred to as the ?payback period? and has been estimated to be 100−1000 years depending on the specific ecosystem involved in the land use change event. Two mechanisms for land use change exist: ?direct? land use change, in which the land use change occurs as part of a specific supply chain for a specific biofuel production facility, and ?indirect? land use change, in which market forces act to produce land use change in land that is not part of a specific biofuel supply chain, including, for example, hypothetical land use change on another continent. Existing land use change studies did not consider many of the potentially important variables that might affect the greenhouse gas emissions of biofuels. We examine here several variables that have not yet been addressed in land use change studies. Our analysis shows that cropping management is a key factor in estimating greenhouse gas emissions associated with land use change. Sustainable cropping management practices (no-till and no-till plus cover crops) reduce the payback period to 3 years for the grassland conversion case and to 14 years for the forest conversion case. It is significant that no-till and cover crop practices also yield higher soil organic carbon (SOC) levels in corn fields derived from former grasslands or forests than the SOC levels that result if these grasslands or forests are allowed to continue undisturbed. The United States currently does not hold any of its domestic industries responsible for its greenhouse gas emissions. Thus the greenhouse gas standards established for renewable fuels such as corn ethanol in the Energy Independence and Security Act (EISA) of 2007 set a

National Survey of E85 and Gasoline Prices
10/1/2008
The objective of this study was to compare the retail prices of E85 (fuel containing 85% ethanol and 15% gasoline) and regular gasoline nationally and regionally over time for one year between July 2007 and June 2008. The United States was divided into six sampling regions. A sampling plan of the approximately 1,200 E85 stations that were operating nationwide at the time was devised to allow statistically significant regional and temporal comparisons of the data to be made within the limited data collection budget available. Results indicate that the price of E85 appears to closely track that of gasoline, and the gap between E85 and gasoline appears to widen somewhat as the price of gasoline increases beyond about $3 per gallon.

National Biofuels Action Plan
10/1/2008
The Biomass Research and Development Board was created by Congress in the Biomass Research and Development Act of 2000, "to coordinate programs within and among departments and agencies of the Federal Government for the purpose of promoting the use of bio-based fuels and bio-based products by (1) maximizing the benefits deriving from Federal grants and assistance; and (2) bringing coherence to Federal strategic planning." This National Biofuels Action Plan is the result of that effort at coordination among Federal departments and agencies.
