At the end of 2021, US President Joe Biden approved an executive order that among other goals included only buying emissions-free vehicles. For light-duty cars and trucks, that has to happen by 2027, with a deadline of 2035 for medium- and heavy-duty vehicles. …One of the latest arms of the federal government to get electrocurious is the US Forest Service, which last week started a yearlong experiment with a trio of Ford F-150 Lightnings. …Over the course of the next 12 months, USFS staff will use the vehicles in day-to-day operations, providing weekly feedback in the form of surveys that record how the vehicles are used, the weather conditions, the kinds of roads, and any bugs that crop up or maintenance that’s required. The USFS’s Northern Research Station in Madison, Wisconsin will compare them to data from forest districts that use conventional trucks.
