In 2015, U.S. consumption of biodiesel exceeded 2 billion gallons. A newly revised document from the U.S. Department of Energy’s Clean Cities program—Biodiesel Handling and Use Guide (Fifth Edition)—serves as a handbook for those who blend, distribute, and use biodiesel and biodiesel blends. (Biodiesel, in this guide, refers to the fuel produced from renewable sources that meets ASTM International Standard D6751-15cƐ1.) The guide provides basic information on the proper and safe use of biodiesel and biodiesel blends in engines and boilers. It is intended to help fleets, individual users, blenders, distributors, and those involved in related activities understand procedures for handling and using biodiesel fuels.
In addition to covering the basics of biodiesel for newcomers to the subject, the guide also provides current considerations for handling and blending B100, B6 to B20 blends, the BQ-9000 program for supply chain management, and taxes and incentives, among other topics.

Last month we learned about how the U.S. Environmental Protection Agency (EPA) determines and reports conventional light-duty vehicle fuel economy ratings. While alternative fuel vehicle (AFV) fuel economy testing is largely similar to that of conventional fuels, the EPA makes some adjustments to account for different vehicle technology and fuel energy content. By tailoring AFV fuel economy testing and reporting, the EPA is able to provide apples-to-apples comparisons and allow consumers to make informed decisions.
What’s Reported:The fuel economy label for all-electric vehicles (EVs) includes all of the same information as that listed for gasoline vehicles (fuel economy, fuel cost savings, annual fuel cost, and emissions). However, EV labels list fuel economy using miles per gallon of gasoline-equivalent (MPGe), sometimes referred to as miles per gasoline gallon equivalent (MPGGE). MPGe represents the number of miles a vehicle can go using a quantity of fuel with the same energy content as a gallon of gasoline. MPGe is a useful way to compare gasoline vehicles with vehicles that use fuel not dispensed in gallons. EV labels also include the following information:
Vehicle Charge Time: Indicates how long it takes to charge a fully discharged battery using Level 2, 240-volt electric vehicle supply equipment.
Driving Range: Estimates the approximate number of miles that a vehicle can travel in combined city and highway driving before the battery must be recharged.
Fuel Consumption Rate: Shows how many kilowatt-hours (kWh) of electricity an EV would use to travel 100 miles. Like gallons per 100 miles, the kWh per 100 miles relates directly to the amount of fuel used. It is an estimated rate of consumption rather than economy (measured in miles per gallon [MPG] or MPGe), which allows for more accurate energy usage comparisons between vehicles.
What’s Tested: To test EV fuel economy, the vehicle battery is fully charged and the vehicle is parked overnight. The next day, the vehicle is tested over successive city cycles until the battery is depleted. The battery is then recharged and the energy consumption of the vehicle is determined by dividing the kWh of energy needed to recharge the battery by the miles traveled by the vehicle. MPGe is based on this figure. The process is repeated for highway driving cycles, and the combined city and highway fuel consumption, and MPGe, is based on the standard ratio of 55% city and 45% highway driving.
Plug-in Hybrid Electric Vehicles
What’s Reported: Like EVs, plug-in hybrid electric vehicle (PHEV) fuel economy labels include fuel cost savings, annual fuel cost, and emissions information. For PHEVs that can use either electricity or gasoline (but only one fuel at a time), also known as non-blended or series PHEVs, labels include information for the fuel economy of both fuel modes. The electricity information is identical to that of EVs, listing charge time, fuel economy in MPGe, and fuel consumption rate in kWh per 100 miles. The gasoline information provides fuel economy in MPG and fuel consumption information in gallons per 100 miles. PHEV fuel economy labels also include electricity only, gasoline only, and combined electricity and gasoline driving range estimates. For PHEVs that use electricity and gasoline at the same time, also known as blended or parallel PHEVs, fuel economy labels reflect the fuel economy, fuel consumption, and range of the vehicle when it uses its standard electricity and gasoline mix.
What’s Tested: Because series PHEVs can use either electricity or gasoline, the EPA determines a vehicle’s fuel economy and fuel consumption based both on its use of only electricity and only gasoline. To determine a PHEV’s electric fuel economy, the EPA issues testing methodology nearly identical to that of EVs. If the gasoline engine is required to complete the test cycle, the EPA methodology uses both the electric energy consumption and the gasoline consumption to calculate the MPGe values for the electric operation only. Vehicle testing for the gasoline operation of the vehicle is similar to any other conventional hybrid electric vehicle. Parallel PHEVs are tested using their standard mix of electricity and gasoline.
Other Alternative Fuels
What’s Reported: The EPA also requires fuel economy information for original equipment manufacturer (OEM) vehicles that use alternative fuels. This includes dedicated natural gas, propane, and hydrogen vehicles, as well as bi-fuel vehicles, such as bi-fuel natural gas, propane, and flexible fuel vehicles (vehicles that may use 51%-83% ethanol-gasoline blends). Note that the EPA does not require fuel economy testing of vehicles converted to run alternative fuels after they are purchased. While the EPA does not list fuel economy information for vehicles that use biodiesel, all diesel vehicles may use fuel blends of up to 5% biodiesel. These vehicles achieve fuel economy very similar to conventional diesel.
For vehicles that use exclusively alternative fuels (e.g., natural gas or hydrogen), the EPA lists fuel economy in MPGe in order to accurately reflect the fuel’s energy content and make easy comparisons with conventional fuel vehicles. Vehicles that can use either alternative fuels or conventional fuel, such as bi-fuel natural gas, bi-fuel propane, and flexible fuel vehicles, have fuel economy, fuel consumption, and range estimates for both the alternative and conventional fuel listed on their fuel economy labels. Fuel economy for alternative fuel use in bi-fuel and flexible fuel vehicles is listed in MPGe, while fuel economy for conventional fuel use is listed in MPG.
What’s Tested: For vehicles that run exclusively on alternative fuels, fuel economy testing methods are similar to those of conventional vehicles. For bi-fuel and flexible fuel vehicles, the vehicle fuel economy is tested as it runs exclusively on each fuel, similar to PHEVs.

United Site Services (USS), the nation’s leading provider of portable restrooms and temporary fence, recently joined Clean Cities’ National Clean Fleets Partnership (NCFP), a public-private initiative within the U.S. Department of Energy (DOE) program to help large private fleets reduce petroleum consumption. The NCFP provides fleets with resources, expertise, and support to incorporate alternative fuels and fuel-saving measures into company operations.
USS provides services to nearly 140,000 customers across the United States through carefully planned aggregate routes. The company’s decision to join the NCFP will positively affect the planning of those routes and lead to reduced petroleum use in service and delivery vehicles. In the past year, USS has also acquired several other companies, including Johnny On The Spot, Progressive Waste Solutions, Readilite & Barricade, and NSC Restrooms, which has given the company the opportunity to expand its already large fleet of vehicles.
The company has already invested several years in industry-leading sustainability practices across its more than 80 operations. Jim Cashman, the company’s senior vice president and chief operating officer, said USS’ decision to partner with Clean Cities is coupled with the company’s standing commitment to make sensible choices that reduce environmental impact.
“As an industry leader, we feel a responsibility to work with DOE to tackle our energy challenges,” Cashman said. “USS has a sizeable fleet of service and delivery vehicles and, through this partnership, can generate better, more efficient ways to operate.”
