Adoption of Plug-in Electric Vehicles: Local Fuel Use and Greenhouse Gas Emissions Reductions Across the U.S

2/1/2024

This report aims to fill a research gap in the local effects of the benefits of electric vehicle (EV) adoption. The report estimates the fuel cost savings and pollution reductions at the state and local zip code levels, considering local fuel prices, vehicle class preferences, vehicle model years, fuel efficiencies, and driving intensities. The report found that EV adoption can result in annual savings up to $2,200. Additionally, the report found that in over 99% of U.S. zip codes, EVs result in overall savings in fuel use and pollution.

Electric Vehicle Charging Infrastructure Trends from the Alternative Fueling Station Locator: Third Quarter 2023

2/1/2024

Electric vehicle (EV) charging infrastructure continues to rapidly change and grow. Using data from the U.S. Department of Energy’s Alternative Fueling Station Locator, this report provides a snapshot of the state of EV charging infrastructure in the United States in the third calendar quarter of 2023 by charging level, network, and location. Additionally, this report measures the current state of charging infrastructure compared with a federal infrastructure requirement scenario. This information is intended to help transportation planners, policymakers, researchers, infrastructure developers, and others understand the rapidly changing landscape of EV charging infrastructure. This is the fifteenth report in a series.

The Future of Biofuels in the United States Transportation Sector

12/29/2023

This article analyses conversion options for biomass to fuels in the U.S. transportation sector, particularly for heavy duty transportation and aviation, based on regional carbon dioxide transportation and injection costs and U.S. tax credits at the time of publication. The article found that that under current credits biofuels play a role only in some regions of the U.S., but a range of policy scenarios, including combining biofuel production with carbon-capture and storage, can lead to biofuels playing a significant role nationally.

AFLEET Assesses Vehicle, Fuel, and Infrastructure Impacts

12/13/2023

AFLEET is a free tool from the U.S. Department of Energy (DOE) that fleet managers can use to quantify the environmental and economic impacts of new fuels and vehicle technologies. The AFLEET fact sheet explains how the tool works and how to access it.

Conceptos básicos sobre los vehículos eléctricos (Electric Vehicles)

12/5/2023

Los vehículos eléctricos (EV, por su sigla en inglés) usan la electricidad como combustible principal o para mejorar la efciencia de los diseños de vehículos convencionales. Los EV incluyen vehículos todo eléctrico, también denominados vehículos eléctricos de batería (BEV, por su sigla en inglés), y vehículos eléctricos híbridos enchufables (PHEV, por su sigla en inglés).

Guidelines to Determine Well-to-Gate Greenhouse Gas (GHG) Emissions of Hydrogen Production Pathways using 45VH2-GREET 2023

12/1/2023

This publication outlines how Argonne National Laboratory’s 2023 GREET model can be used to calculate lifecycle emissions of hydrogen production under a well-to-gate system boundary. The paper outlines the methodology used to calculate the well-to-gate emissions of each of the hydrogen production pathway technologies currently represented in the tool, instructions for how users can run the GREET model, and the annual update process for the tool.

Charging Ahead: How Government Agencies Can Support the Electrification of Private Fleet Vehicles

12/1/2023

This toolkit is a resource for government agencies seeking ways to teach private fleet operators and private sector stakeholders about electric vehicles. It is designed to help government agencies consider, plan, coordinate, and support this adoption. Government agencies can use the toolkit to identify key partners, advance high-impact policy tools, and assist firms in pursuing fleet electrification.

Clean Cities Alternative Fuel Price Report, October 2023

11/29/2023

The Clean Cities Alternative Fuel Price Report for October 2023 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 1, 2023 and October 15, 2023, 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 2 reports that the nationwide average price (all amounts are per gallon) for regular gasoline has increased 13 cents from $3.59 to $3.72; diesel increased 64 cents from $3.88 to $4.52; CNG decreased 1 cent from $2.86 to $2.85; ethanol (E85) increased 10 cents from $2.95 to $3.05; propane increased 4 cents from $3.25 to $3.29; and biodiesel (B20) increased 65 cents from $3.77 to $4.42.

According to Table 3, CNG is 87 cents less than gasoline on an energy-equivalent basis and E85 is 24 cents more than gasoline on an energy-equivalent basis.

The Current State of Light-Duty Electric Vehicle Supply Equipment Costs: An Assessment of Contemporary Understanding

11/28/2023

This technical study combines a hybrid meta-analysis with a literature review to assess the current state of knowledge regarding electric vehicle supply equipment (EVSE) costs. The study presents a novel convention for analyzing EVSE costs that includes EVSE application type (commercial or residential), power level (Level 1, 2, or direct current (DC) fast charging), and type of cost measure (hardware, installation, operation, and total cost). These measures are intended to be used as a new standard to make EVSE cost assessments more accessible, and to make cost tracking more ubiquitous.

Charge Up Your Town: Best Management Practices to Ensure Your Town is EV Ready

11/1/2023

With a goal of reducing statewide pollution by 80% below 2006 levels by 2050, the State of New Jersey is making a concerted effort to electrify its transportation sector, which currently produces over 40% of the state’s pollution. This paper provides a case study on how state governments can support local municipalities in successfully converting to light-duty electric vehicle (EV) fleets and installing adequate electric vehicle supply/service equipment (EVSE). As municipalities are often in charge of installing EVSE across New Jersey, local government understanding of statewide ordinances, EV charging station installation requirements, and available financial incentives is imperative towards achieving statewide pollution reduction targets. Other state and local governments can adapt this guide to meet their own parameters.
