Plug-In Electric Vehicle Handbook for Workplace Charging Hosts
8/1/2013
Plug-in electric vehicles (PEVs) have immense potential for increasing the country's energy, economic, and environmental security, and they will play a key role in the future of U.S. transportation. By providing PEV charging at the workplace, employers are perfectly positioned to contribute to and benefit from the electrification of transportation. This handbook answers basic questions about PEVs and charging equipment, helps employers assess whether to offer workplace charging for employees, and outlines important steps for implementation.
Clean Cities Alternative Fuel Price Report, July, 2013
8/1/2013
The Clean Cities Alternative Fuel Price Report for July 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 July 12, 2013 and July 26, 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 increased 6 cents from $3.59 to $3.65; diesel has decreased 8 cents from $3.99 to $3.91; CNG price has increased 4 cents, from $2.10 to $2.14; ethanol (E85) has decreased 7 cents from $3.30 to $3.23; propane in unchanged at $2.73; and biodiesel (B20) has decreased 22 cents from $4.11 to $3.89.
According to Table 2, CNG is about $1.51 less than gasoline on an energy-equivalent basis, while E85 is about $0.92 more than gasoline on an energy-equivalent basis.

Case Study - Liquefied Natural Gas
6/1/2013
As a part of the U.S. Department of Energy's broad effort to develop cleaner transportation technologies that reduce U.S. dependence on imported oil, this study examines advanced 2011 natural gas fueled trucks using liquefied natural gas (LNG) replacing older diesel fueled trucks. The trucks are used 6 days per week in regional city-to-landfill long hauls of incinerator waste with two fills per day. This is a workable fit for the limited range LNG trucks. Reduction of fuel costs and harmful emissions relative to the replaced trucks are significant.

Which is Greener: Idle, or Stop and Restart? Comparing Fuel Use and Emissions for Short Passenger-Car Stops
2/11/2013
The argument against parking and going into a business, rather than using a drive-through window, has been that the emissions and fuel use associated with restarting your car are greater than those incurred by idling for that time. Argonne National Laboratory undertook a series of measurements to determine whether this was true, by comparing actual idling fuel use and emissions with those for restarting. This work seeks to answer the question: Considering both fuel use and emissions, how long can you idle in a queue before impacts from idling are greater than they are for restarting? Fuel use and carbon dioxide emissions are always greater for idling over 10 seconds; the crossover times are found to vary by pollutant.

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.
