Clean Cities 2010 Annual Metrics Report
10/1/2012
Each year, the U.S. Department of Energy (DOE) asks Clean Cities coordinators to submit an annual report of their activities and accomplishments for the previous calendar year. Data and information are submitted to an online database that is maintained as part of the Alternative Fuels and Advanced Vehicles Data Center (AFDC) at the National Renewable Energy Laboratory (NREL). Coordinators submit a range of data that characterizes 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 initiatives, fuel economy activities, and programs to reduce vehicle miles traveled (VMT). NREL analyzes the data and translates them into gasoline use reduction impacts, which are summarized in this report.

Plug-In Electric Vehicle Deployment in the Northeast; A Market Overview and Literature Review
9/1/2012
Electric vehicles have the potential to decrease our nation's dependence on oil and drastically reduce greenhouse gas emissions from the transportation sector. In an effort to stimulate economic growth, decrease the United States' dependence on oil, and lessen the operating cost of personal transportation, the federal government issued a final rule in 2012 requiring new cars to average 54.5 miles per gallon by 2025. This goal is ambitious and will be difficult to accomplish without significant numbers of alternative fuel vehicles. Several alternative fuels are currently available, but electric vehicles (EVs) are emerging as the predominant alternative for passenger vehicles. While EVs are hitting the market and offer numerous advantages, such as zero tailpipe emissions, lower fuel costs, and the convenience of filling up at home, a number of barriers stand in the way of wide-scale EV deployment.
This literature review, prepared by the Center for Climate and Energy Solutions, provides an overview of plug-in electric vehicle (PEV) deployment in the Northeast and Mid-Atlantic states. The report assesses current electric vehicle and electric vehicle charging station technology, looks at the state of PEV markets, reviews the benefits of PEV deployment, and identifies the barriers and challenges to PEVs in gaining market acceptance. The literature review is intended to serve as a resource for consumers and policy makers who seek to better understand the nature of electric vehicle deployment in this region and related challenges.

The U.S. Environmental Protection Agency (EPA) is adopting changes to the regulations found in 40 CFR part 85 subpart F for clean alternative fuel conversion manufacturers. This action affects regulations applicable to manufacturers of light-duty vehicle and heavy-duty highway vehicle and engine clean alternative fuel conversion systems. The revisions will streamline the compliance process while maintaining environmentally protective controls.
Experiences with Compressed Natural Gas in Colorado Vehicle Fleets; Case Study Analysis
8/1/2012
This series of case studies is the product of in-person and telephone interviews with three Colorado fleet managers who use compressed natural gas (CNG) as a vehicle fuel and interviews with other CNG stakeholders. The fleets were selected using criteria that are intended to increase the usefulness of the overall product, including geographic diversity, length of CNG experience, diversity of vehicles, and ownership model. The case studies are based on a framework constructed with broad stakeholder input, designed to provide detailed information on fleet manager experiences with CNG vehicles and fueling infrastructure.
Featured fleets include the following: Republic Services (Republic), a private sector waste and environmental management firm with a CNG fleet based in the Denver metro area; Denver International Airport (DIA), an airport with more than 15 years of experience with CNG and proven success as a CNG hub; and City of Grand Junction, a Western Slope municipality with a public/private partnership to provide public CNG fueling.
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.
Clean Alternative Fuel Vehicle and Engine Conversions; Final Rule
4/8/2011
EPA is streamlining the process by which manufacturers of clean alternative fuel conversion systems may demonstrate compliance with vehicle and engine emissions requirements. Specifically, EPA is revising the regulatory criteria for gaining an exemption from the Clean Air Act prohibition against tamperingfor the conversion of vehicles and engines to operate on a clean alternativefuel. This final rule creates additional compliance options beyond certification that protect manufacturers of clean alternative fuel conversion systems against a tampering violation, depending on the age of the vehicle orengine to be converted. The new options alleviate some economic and proceduralimpediments to clean alternative fuel conversions while maintainingenvironmental safeguards to ensure that acceptable emission levels from converted vehicles are sustained.
Blueprint for a Secure Energy Future
3/30/2011
The Blueprint for a Secure Energy Future outlines a three-part strategy: 1) Develop and secure America's energy supplies; 2) provide consumers with more choices of alternative fuels and advanced and fuel-efficient vehicles, alternative means of transportation; and 3) innovate our way to a clean energy future by creating markets for innovative clean technologies that are ready to deploy and by funding cutting edge research to produce the next generation of technologies.

Electric Vehicle Infrastructure: A Guide for Local Governments in Washington State
7/1/2010
In 2009 the Washington State Legislature enacted a new law designed to encourage electric vehicles. To create a consistent regulatory framework that would help this industry grow across Washington State, the legislature required the Puget Sound Regional Council and Department of Commerce to develop guidance for local governments. To meet this requirement, a broad-based technical advisory committee made up of local governments, charging equipment vendors, utilities, ports, state agencies, and consumer interests was formed. The state's new electric vehicle law requires that all local governments in Washington State allow electric vehicle charging stations in most of their zoning categories. Allowing charging stations creates the need to address a number of issues beyond zoning. These include on-street and off-street signage, charging station design standards, parking enforcement, accessibility for all users, SEPA exemptions, and more. These issues are addressed in this document.

An Action Plan for Cars: The Policies Needed to Reduce U.S. Petroleum Consumption and Greenhouse Gas Emissions
12/1/2009
Reducing petroleum consumption and GHG emissions from cars and light?]duty trucks in the United States over the next several decades requires that we implement a clear and coordinated set of policies now. This report describes a portfolio of policies which, in the view of the authors, is needed to put personal vehicle transportation on the road to sustainability in the longer term. To incentivize adoption of more fuel efficient vehicles, we propose coupling existing near?]term fuel economy standards with a feebate incentive program and gradual increases in fuel taxes. We further propose driver education initiatives that would give vehicle owners information on how to maximize fuel savings in their purchase and driving decisions. Finally, we underscore the need for a long?]term strategy for fuels that evaluates fuels?]related programs based on their contribution to reducing life?]cycle petroleum consumption and greenhouse gas (GHG) emissions. Together, these policies offer a robust plan of action that will focus and streamline current efforts to achieve these two important national goals. Perhaps most importantly, this plan lays a much?]needed foundation for a comprehensive, adaptable long?]term policy effort. A more detailed summary of the recommended set of policy measures can be found in Section 2.

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.

Energy Use and Emissions Comparison of Idling Reduction Options for Heavy-Duty Diesel Trucks
11/15/2008
Pollution and energy analyses of different idling reduction (IR) technologies have been limited to localized vehicle emissions and neglected upstream energy use and regional emissions. In light of increasing regulation and government incentives for IR, we analyzed the full-fuel-cycle effects of contemporary approaches. Our analysis incorporates direct impacts at the truck and upstream energy use and emissions estimates from the GREET model with published climate and vehicle operation data. We compared emissions, energy use, and proximity to urban populations for nine alternatives, including idling, electrified parking spaces, auxiliary power units, and several combinations of these.
