Question of the Month: What are state and local governments doing to incentivize alternative fuels and alternative fuel vehicles (AFVs)?
March 01, 2017
There are many notable incentive activities at the state and local levels. Many states offer incentives for alternative fuels that advance specific environmental and energy security goals, while cities provide even more localized support.
States are targeting vehicles, infrastructure, and other means to encourage AFV adoption

Question of the Month: How is fuel economy determined and reported for alternative fuel vehicles?
Answer: 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.

Question of the Month: How are conventional light-duty vehicle fuel economy ratings determined and reported?
Answer: It’s important to understand the who, what, when, where, and why (and how!) of fuel economy testing and labeling. In particular, you may be interested in the recent changes described below (see “When” section).
October Question of the Month: What idle reduction technologies are available for heavy-duty vehicles?
October 21, 2016
Heavy-duty vehicle idling, or running a vehicle’s engine while it is not in motion, occurs for a number of reasons, including temperature control during required rest stops, powering electronic equipment, and to avoid cold starting the vehicle. According to Argonne National Laboratory (Argonne), more than 6 billion gallons of diesel and gasoline fuel are wasted by vehicle engine idling—with half from medium- and heavy-duty vehicles alone.
