Motor fuel taxes were established to finance our nation's transportation infrastructure, yet evolving economic, political, and technological influences are constraining this ability. At the federal level, the Highway Trust Fund (HTF), which is primarily funded by motor fuel taxes, has become increasingly dependent on general fund contributions and short-term reauthorizations to prevent insolvency. As a result, there are discussions at both the federal and state levels in which stakeholders are examining the future of motor fuel excise taxes as well as the role of electric and alternative fuel vehicles in that future. On July 1, 2015, six states increased their motor fuel tax rates.
A new report from the National Renewable Energy Laboratory (NREL) explores the role of alternative fuels and energy efficient vehicles in motor fuel taxes. Throughout the United States, it is common practice for federal, state, and local governments to tax motor fuels on a per gallon basis to fund construction and maintenance of our transportation infrastructure. In recent years, however, expenses have outpaced revenues creating substantial funding shortfalls that have required supplemental funding sources. While rising infrastructure costs and the decreasing purchasing power of the gas tax are significant factors contributing to the shortfall, the increased use of alternative fuels and more stringent fuel economy standards are also exacerbating revenue shortfalls. The current dynamic places vehicle efficiency and petroleum use reduction polices at direct odds with policies promoting robust transportation infrastructure. Understanding the energy, transportation, and environmental tradeoffs of motor fuel tax policies can be complicated, but recent experiences at the state level are helping policymakers align their energy and environmental priorities with highway funding requirements.

A wide array of federal incentives support the development and deployment of alternatives to conventional fuels and engines in transportation. These incentives include tax deductions and credits for vehicle purchases and the installation of refueling systems, federal grants for conversion of older vehicles to newer technologies, mandates for the use of biofuels, and incentives for manufacturers to produce alternative fuel vehicles. The current array of incentives for alternative fuels and related technologies do not reflect a single, comprehensive strategy, but rather an aggregative approach to a range of discreet public policy issues, including goals of reducing petroleum consumption and import dependence, improving environmental quality, expanding domestic manufacturing, and promoting agriculture and rural development. Current federal programs are administered by five key agencies: Department of the Treasury, Department of Energy, Department of Transportation, Environmental Protection Agency, and the U.S. Department of Agriculture. The incentives and programs described in this report are organized by the responsible agency. Treasury (through the Internal Revenue Service, IRS) administers tax credits and deductions for alternative fuel and advanced technology vehicle purchases, expansion of alternative fuel refueling infrastructure, and incentives for the production and/or distribution of alternative fuels. Many of these incentives have expired in recent years and may or may not be reinstated. DOE (mainly through the Office of Energy Efficiency and Renewable Energy, EERE) administers research and development (R&D) programs for advanced fuels and transportation technology, grant programs to deploy alternative fuels and vehicles, and a loan program to promote domestic manufacturing of high efficiency vehicles. DOT (mainly through the Federal Highway Administration, FHWA, and Federal Transit Administration, FTA) administers grant programs to deploy “clean fuel” buses and other alternative fuel vehicles. DOT (through the National Highway Traffic Safety Administration, NHTSA) also administers federal Corporate Average Fuel Economy (CAFE) standards, which include incentives for production of alternative fuel vehicles. EPA (mainly through the Office of Transportation and Air Quality, OTAQ) administers the Renewable Fuel Standard, which mandates the use of biofuels in transportation. EPA also administers grant programs to replace older diesel engines with newer technology. USDA (mainly through the Rural Business-Cooperative Service, RBS) administers grant, loan, and loan guarantee programs to expand agricultural production of biofuel feedstocks, conduct R&D on biofuels and bioenergy, and establish and expand facilities to produce biofuels, bioenergy, and bioproducts.
Written primarily for fleet management personnel with purchasing, maintenance, or operations responsibilities, Alternative Fuels: Emissions, Economics, and Performance provides essential information for those who are considering adding alternatively-fueled vehicles to their fleets. Readers will gain a solid understanding of the fundamentals of alternative fuels and the factors that need to be considered when evaluating their use. No prior knowledge of alternative fuels is necessary. Basic information on the various alternative fuels and objective data on the costs of converting, fueling, and operating alternatively-fueled vehicles is covered in this book. Fuel cost, performance, reliability, and availability are addressed. The book also discusses the 1990 amendments to the Clean Air Act and the 1992 Comprehensive National Energy Policy Act. A summary of Texas' state law, considered to be representative of state legislation on alternative fuels and a glossary of key terms, are also included. Eight chapters cover: Review of Engine Technology; Characteristics of Alternative Fuels; Conversion of Spark Ignition Engines; Conversion of Compression Ignition Engines; Refueling Facilities; Legislation and Policies; and Cost Considerations. The book is also an ideal introduction to the topic for legislators, administrators, educators, and anyone interested in learning more about alternate fuels.
An overview of alternative fuel vehicles. Includes chapters on: regulations and requirements in the U.S. and California; electric vehicles; ethanol-powered/flexible fuel vehicles; methanol-powered/flexible fuel vehicles; natural gas -powered vehicles; propane/LPG-powered vehicles; heavy-duty vehicles and engines; other alternative and clean fuels; locations of alternative fuel facilities; and the future of alternative fuel research. Glossary and bibliography. Tables, contact lists and maps.
