Clean Cities Alternative Fuel Price Report, January, 2013
2/1/2013
The Clean Cities Alternative Fuel Price Report for January 2013 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 10, 2013 and January 25, 2013, 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 decreased 53 cents from $3.82 to $3.29; diesel has decreased 17 cents from $4.13 to $3.96; CNG price has decreased 2 cents from $2.12 to $2.10; ethanol (E85) has decreased 30 cents from $3.47 to $3.17; propane has increased 12 cents from $2.56 to $2.68; and biodiesel (B20) has decreased 13 cents from $4.18 to $4.05.
According to Table 2, CNG is about $1.19 less than gasoline on an energy-equivalent basis, while E85 is about $1.19 more than gasoline on an energy-equivalent basis.

Consumer Convenience and the Availability of Retail Stations as a Market Barrier for Alternative Fuel Vehicles, Preprint
1/1/2013
The availability of retail stations can be a significant barrier to the adoption of alternative fuel light-duty vehicles in household markets. This is especially the case during early market growth when retail stations are likely to be sparse and when vehicles are dedicated in the sense that they can only be fuelled with a new alternative fuel. For some bi-fuel vehicles, which can also fuel with conventional gasoline or diesel, limited availability will not necessarily limit vehicle sales but can limit fuel use. The impact of limited availability on vehicle purchase decisions is largely a function of geographic coverage and consumer perception. In this paper we review previous attempts to quantify the value of availability and present results from two studies that rely upon distinct methodologies. The first study relies upon stated preference data from a discrete choice survey and the second relies upon a station clustering algorithm and a rational actor value of time framework. Results from the two studies provide an estimate of the discrepancy between stated preference cost penalties and a lower bound on potential revealed cost penalties.

Transitions to Alternative Vehicles and Fuels
1/1/2013
For a century, almost all light-duty vehicles (LDVs) have been powered by internal combustion engines (ICEs) operating on petroleum fuels. Energy security concerns over petroleum imports and the effect of greenhouse-gas (GHG) emissions on global climate are driving interest in alternatives. This report assesses the potential for reducing petroleum consumption and GHG emissions by 80% across the U.S. LDV fleet by 2050, relative to 2005. It examines the current capability and estimated future performance and costs for each vehicle type and non-petroleum-based fuel technology as options that could significantly contribute to these goals. By analyzing scenarios that combine various fuel and vehicle pathways, the report also identifies barriers to implementation of these technologies and suggests policies to achieve the desired reductions. Several scenarios are promising, but strong, effective, and sustained but adaptive policies such as research and development (R&D), subsidies, energy taxes, or regulations will be necessary to overcome barriers such as cost and consumer choice.

Biofuels Issues and Trends
10/1/2012
Biofuels is a collective term for liquid fuels derived from renewable sources, including ethanol, biodiesel, and other renewable liquid fuels. This report focuses on ethanol and biodiesel, the most widely available biofuels. From 2009 to the middle of 2012, the U.S. biofuels industry increased its output and prepared to meet an expanded Renewable Fuel Standard (RFS2), which requires increasing volumes of biofuels use. In 2011, the biofuels industry transitioned away from tax incentives for non-cellulosic biofuels, which expired at the end of 2011. Annual ethanol and biodiesel consumption, production, imports, and exports during 2009-11 are summarized in Table 1.

Annual Energy Outlook 2012; with Projections to 2035
6/1/2012
The projections in the U.S. Energy Information Administration's (EIA's) Annual Energy Outlook 2012 (AEO2012) focus on the factors that shape the U.S. energy system over the long term. Under the assumption that current laws and regulations remain unchanged throughout the projections, the AEO2012 Reference case provides the basis for examination and discussion of energy production, consumption, technology, and market trends and the direction they may take in the future. It also serves as a starting point for analysis of potential changes in energy policies. But AEO2012 is not limited to the Reference case. It also includes 29 alternative cases (see Appendix E, Table E1), which explore important areas of uncertainty for markets, technologies, and policies in the U.S. energy economy. Many of the implications of the alternative cases are discussed in the "Issues in focus" section of this report.
Key results highlighted in AEO2012 include continued modest growth in demand for energy over the next 25 years and increased domestic crude oil and natural gas production, largely driven by rising production from tight oil and shale resources. As a result, U.S. reliance on imported oil is reduced; domestic production of natural gas exceeds consumption, allowing for net exports; a growing share of U.S. electric power generation is met with natural gas and renewables; and energy-related carbon dioxide emissions remain below their 2005 level from 2010 to 2035, even in the absence of new Federal policies designed to mitigate greenhouse gas (GHG) emissions.

E15 Misfueling Mitigation Plan
3/2/2012
The purpose of this Misfueling Mitigation Plan (MMP) is to set forth how the plan submitter will comply with the misfueling mitigation conditions established by the U.S. Environmental Protection Agency (EPA or the Agency) in its October 13, 2010, and January 21, 2011, partial waivers allowing fuel and fuel additive manufacturers to introduce into U.S. commerce ethanol blends containing greater than 10 volume percent and no more than 15 volume percent ethanol (E15) for use in model year 2001 and newer light duty motor vehicles. The MMP, which is intended to reduce the potential of E15 being used in all engines, vehicles and equipment for which waivers have not been granted by the Agency, addresses the following required elements: E15 pump labeling, tracking of E15 through the supply chain through product transfer documentation, and implementation surveys of E15 content and labeling compliance.
Because this plan has been developed as a model plan, a company that wishes to use it must notify EPA in writing that the company seeks approval of the plan for the company's use in meeting the requirements for an MMP. Before deciding whether to approve a plan, EPA may seek additional information and/or misfueling mitigation measures as appropriate in view of the company's circumstances. EPA must approve a company's submission of this MMP before the company may use it to demonstrate its compliance with the partial waiver conditions.

Life-Cycle Analysis of Shale Gas and Natural Gas
12/1/2011
The technologies and practices that have enabled the recent boom in shale gas production have also brought attention to the environmental impacts of its use. Using the current state of knowledge of the recovery, processing, and distribution of shale gas and conventional natural gas, we have estimated up-to-date, life-cycle greenhouse gas emissions. In addition, we have developed distribution functions for key parameters in each pathway to examine uncertainty and identify data gaps - such as methane emissions from shale gas well completions and conventional natural gas liquid unloadings - that need to be addressed further. Our base case results show that shale gas life-cycle emissions are 6% lower than those of conventional natural gas. However, the range in values for shale and conventional gas overlap, so there is a statistical uncertainty regarding whether shale gas emissions are indeed lower than conventional gas emissions. This life-cycle analysis provides insight into the critical stages in the natural gas industry where emissions occur and where opportunities exist to reduce the greenhouse gas footprint of natural gas.
